- OBJECTIVE: To evaluate the effect of grafting with strontium (Sr)-loaded deproteinized bovine bone (DBB) on bone healing in calvarial critical size defects (CSD) in rats. MATERIAL AND METHODS: Two circular bone defects (5 mm in diameter) were created in the calvaria of 42 rats. One of the defects, randomly chosen, was grafted with (a) DBB, (b) DBB loaded with 19.6 mug/g of Sr (DBB/Sr1), or (c) DBB loaded with 98.1 mug/g of Sr (DBB/Sr2). The other defect was left empty as negative control. Groups of seven animals from each of the groups were euthanized 15 and 60 days post-op. Bone healing in the CSD was evaluated by micro-CT and histology/histomorphometry and immunohistochemistry. RESULTS: DBB/Sr2-grafted sites showed statistically significantly shorter radiographic residual defect length compared with DBB/Sr1- and DBB-grafted sites, and with empty controls at 60 days. Further, the amount of new bone formation in the DBB/Sr1- and DBB/Sr2-grafted sites was significantly higher compared with that in the DBB-grafted sites at 60 days. A larger number of DBB/Sr1- and DBB/Sr2-grafted sites presented with no- or only limited to mild inflammation, compared with the DBB-grafted sites, especially at 60 days. Higher expression of osteocalcin was observed in DBB/Sr1- and DBB/Sr2-grafted sites as compared to DBB-grafted sites. CONCLUSION: Grafting with Sr-loaded DBB enhanced bone formation in CSD in rats, when compared with grafting with non-loaded DBB. CLINICAL RELEVANCE: Grafting with Sr-loaded DBB may enhance bone formation in bone defects.

- Objectives: The aims of this study were to quantify salivary concentrations of bisphenol A (BPA) and to assess if presence of dental composite fillings is associated with higher BPA levels in saliva. Materials and methods: Twenty individuals with six or more tooth surfaces filled with polymer-based dental materials (composite group) and 20 individuals without any polymer-based materials (control group) were included in the study. Saliva was collected in polypropylene tubes and stored at −80 °C before analysis. Concentration of free (unconjugated) and total bisphenol A was determined by liquid chromatography/mass spectrometry (LC/MS). Values below limit of detection (0.1 ng/mL) were set to one-half of the limit of detection. Mann-Whitney U test (one sided; the Exact Tests Option in IBM-SPSS version 21) was used for the statistical analyses. Results: The concentration of BPA in saliva was very low. In the composite group, 8 of 20 samples had detectable concentrations of BPA. In the control group, 3 of 20 samples had detectable concentrations of BPA. Statistical analysis indicated that the concentration of unconjugated BPA was slightly higher in the composite group (p = 0.044) than in the control group. Conclusions: Presence of dental composites may be associated with slightly higher concentration of unconjugated BPA in saliva. However, additional studies using sensitive analytical methods are needed before firm conclusions can be drawn. Influence from other factors, like food intake and time of the day for saliva sampling, must be considered. Clinical relevance: The relative contribution of existing polymer-based dental fillings to total BPA exposure seems to be low.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To perform a within-subject comparison of the cortical bone micro-architecture of the maxillary sinus floor (MSF) to that of the buccal aspect of the anterior and posterior maxilla. Methods: Micro-CT scans of the buccal aspect of the anterior and posterior maxilla and of the MSF in 14 human anatomical specimens were recorded. Within-subject comparisons were performed for cortical thickness (Ct.Th) and porosity (Ct.Po), average pore volume (AvgPo.V), and pore density (Po.Dn). Results: The MSF presented the lowest and the anterior maxilla the highest Ct.Th, while Ct.Po was significantly higher at the MSF compared to the posterior maxilla (p = 0.021). No relevant differences were recorded for AvgPo.V and Po.Dn among regions (p > 0.067). Further, an increased Ct.Th at the MSF was significantly associated with a lower Po.Dn, while a higher Ct.Th and an increased AvgPo.V in the anterior maxilla were associated with a higher Ct.Th and an increased AvgPo.V, respectively, in the posterior maxilla and MSF. Finally, within each region, the AvgPo.V was associated positively with Ct.Po and negatively with Po.Dn. Conclusions: The cortical bone of the MSF is slightly less thick and slightly more porous compared to the cortical bone at the buccal aspect of the anterior and posterior maxilla. Clinical relevance: During lateral and vertical bone augmentation procedures, the cortical recipient bone is perforated several times to open the bone marrow compartment to facilitate provision of osteoinductive cells and molecules in the augmented space. Whether it is meaningful to approach the MSF in a similar way during MSF augmentation procedures or whether the slightly more porous structure of the MSF observed herein reduces the cortical barrier function already sufficiently has to be assessed in future clinical trials.

- OBJECTIVES: This study aimed to assess the oral health status and dental care behaviours of patients treated for head and neck squamous cell carcinoma (HNSCC) in an Austrian tertiary hospital. MATERIALS AND METHODS: Dental care behaviours, oral hygiene level, caries, and periodontal parameters were assessed in 48 patients treated for HNSCC >6 months ago. RESULTS: Only 52 % requested a dental check-up after HNSCC diagnosis and prior to treatment, and of those, 80 % received some type of dental treatment. At time-point of clinical examination, 69 % of the patients had consulted a dentist within the last year, but 88 % still needed dental treatment; 75 % had at least one tooth with caries and 78 % had moderate to severe periodontitis. CONCLUSION: Although it was recommended, only half of the patients did consult a dentist prior to HNSCC treatment and oral health appeared, in general, low prioritized. CLINICAL RELEVANCE: About 90 % of the current group of head and neck squamous cell carcinoma cancer patients presented large treatment needs, both in regard with caries and periodontal disease, about 20 months after cancer treatment.

- Objectives The present systematic review compared the effec- tiveness of soft tissue substitutes (STSs) and autogenous free gingival grafts (FGGs) in non-root-coverage procedures to increase keratinized tissue (KT) width around teeth. Materials and methods Included studies fulfilled the follow- ing main eligibility criteria: (a) preclinical in vivo or human controlled trials using FGG as control, (b) non-root-coverage procedures, and (c) assessment of KT width. Meta-analysis was performed on the gain in KT width (primary outcome variable) and several secondary variables. Results Eight human trials with short observation time evalu- ating five different STSs were identified. FGG yielded consis- tently significantly (p < 0.001) larger increase in KT width irrespective whether the comparison regarded an acellular ma- trix or a tissue-engineered STS. Further, FGG yielded consis- tently ≥2 mm KT width postoperatively, while use of STS did not, in the few studies reporting on this outcome. On the other hand, STSs resulted in significantly better aesthetic outcomes and received greater patient preference (p < 0.001). Conclusions Based on relatively limited evidence, in non- root-coverage procedures, FGG (1) resulted consistently in significantly larger increase in KT width compared to STS and (2) yielded consistently ≥2 mm KT width postoperatively, while STSs did not. STSs yielded significantly better aesthetic outcomes, received greater patient preference, and appeared safe. Clinical relevance Larger and more predictable increase in KT width is achieved with FGG, but STSs may be considered when aesthetics is important. Clinical studies reporting rele- vant posttreatment outcomes, e.g., postop KT width ≥2 mm, on the long-term (>6 months) are warranted.

- OBJECTIVES: Impacted and transmigrated mandibular canines differ greatly in incidence, etiopathology, associated anomalies, and treatment prospects, when compared to their maxillary counterparts. The aim of this study was to provide a detailed analysis of 3D radiographic imaging data of impacted mandibular canines. MATERIALS AND METHODS: In a retrospective cross-sectional study, CT/CBCT data of 88 patients with a total of 94 impacted mandibular canines were analysed. Evaluated parameters included location, morphology, neighbouring structures, associated anomalies, the influence of those factors on mandibular canine transmigration, as well as applied treatment. RESULTS: Transmigration was found to occur in 40.4% of impacted mandibular canines. Transmigrated canines were located significantly more basally and horizontally angulated. Further, transmigration was significantly associated with a lack of contact to adjacent teeth and the canine's apex not contacting the mandibular cortical bone. The overall incidence of root resorptions of adjacent teeth related to impacted mandibular canines was 7.3% and was more likely, if the canine was lingually impacted. While about half of the non-transmigrated impacted canines were orthodontically aligned, half of the transmigrated canines were surgically removed. Monitoring was the second most applied treatment strategy for both groups, and no canines were autotransplantated. CONCLUSIONS: Root resorption of adjacent teeth and transmigration are commonly occurring phenomena related to impacted mandibular canines. CLINICAL RELEVANCE: Treatment often entails the surgical removal of the canine-especially in cases of transmigration. The findings emphasise the importance of early diagnosis and CT/CBCT imaging for further diagnostics and future research of impacted mandibular canines.

Tidskriftsartikel (refereegranskat)abstract
- Background: Feeding and swallowing impairment are present in up to 80% of oculo-auriculo-vertebral spectrum (OAVS) patients. Salivary gland abnormalities have been reported in OAVS patients but their rate, features, and relationship with phenotype severity have yet to be defined.Material and methods: Parotid and submandibular salivary gland hypo/aplasia was evaluated on head MRI of 25 OAVS patients (16 with severe phenotype, Goldenhar syndrome) and 11 controls.Results: All controls disclosed normal salivary glands. Abnormal parotid glands were found exclusively ipsilateral to facial microsomia in 21/25 OAVS patients (84%, aplasia in six patients) and showed no association with phenotype severity (14/16 patients with Goldenhar phenotype vs 7/9 patients with milder phenotype, p = 0.6). Submandibular salivary gland hypoplasia was detected in six OAVS patients, all with concomitant ipsilateral severe involvement of the parotid gland (p < 0.001). Submandibular salivary gland hypoplasia was associated to Goldenhar phenotype (p < 0.05). Parotid gland abnormalities were associated with ipsilateral fifth (p < 0.001) and seventh cranial nerve (p = 0.001) abnormalities. No association was found between parotid gland anomaly and ipsilateral internal carotid artery, inner ear, brain, eye, or spine abnormalities (p > 0.6).Conclusions: Salivary gland abnormalities are strikingly common in OAVS. Their detection might help the management of OAVS-associated swallowing and feeding impairment.

- The caries preventive effect of long-term use (1year) of low-dosage (2.5g/die) of xylitol chewing gum in a high-caries-risk adult population was evaluated.In this randomized clinical trial, 179 high-caries-risk adults were assigned to two experimental groups, xylitol and polyols. Caries status, salivary mutans streptococci (MS), and plaque pH were re-evaluated after 2years from baseline in 66 xylitol and 64 polyol subjects. Outcomes (the net caries increment for initial, moderate, and extensive caries lesions and for the caries experience) were evaluated using the nonparametric Mann-Whitney U test.The total caries experience increment was 1.25±1.26 in the xylitol group and 1.80±2.33 in the polyol group (p=0.01). Subjects treated with xylitol chewing gums had a reduction of risk rate at tooth level of 23% with respect to those treated with polyols with a number needed to treat of 55 teeth. The area under the curve at pH 5.7 was statistically significantly lower (p=0.02) during the experimental period in the xylitol group. A decrease of the concentration of salivary MS was noted in the xylitol group (p<0.01).Subjects using the low-dose xylitol chewing gum showed a significantly lower increment of initial and extensive caries lesions and overall a lower increment of caries experience.One-year use of chewing gums provides an effective means for the prevention of caries disease.NCT02310308.

- ObjectiveThis study aimed to investigate the presence of BRAF V600E mutation in mandible ameloblastomas by correlating clinical and imaging data on the cases studied.MethodsEighty-four cases diagnosed as mandibular ameloblastoma were selected for analysis. The specimens were submitted to immunohistochemistry for detection of BRAF V600E mutated protein. Clinical-pathological data such as age, gender, tumour size, mandibular location, radiographic aspects, histological type and sub-type, and tumour status were collected. The clinical-pathological parameters were categorised and analysed according to BRAF V600E detection.ResultsOf the 84 patients, 78.6% (66 cases) demonstrated positivity for anti-BRAF V600E antibody, whereas 18 were negative (21.4%). The correlation between BRAF expression and variables showed statistical significances for mandibular location (P=0.0353) and tumour size (P=0.008), whereas no statistical significance was observed for gender, age, radiographic aspect, histological pattern, histological sub-type and tumour status. Multivariate logistic regression revealed a significant risk for BRAF positivity in tumours with posterior mandibular location (OR=7.23, P=0.0451) and size >4cm (OR=7.29, P=0.0150).ConclusionBRAF V600E mutation is common in mandibular ameloblastomas, especially in cases of tumours larger than 4cm and in the posterior region of the mandible. In addition, this mutation can occur regardless of histological type of the tumour, age, gender, radiographic aspect and tumour status.Clinical significanceThe association between clinical-pathologic features and BRAF V600E mutation in ameloblastomas may provide directions for the treatment of this neoplasia. The use of BRAF inhibitors for targeted therapy could lead to an establishment of an alternative compared to the resective surgery.

- The observer score of the trabecular pattern on panoramic radiographs is known to be a strong predictor of bone fractures. The aim of this study was to enhance the predictive power of panoramic radiographs by means of texture analysis methods.The study followed 304 postmenopausal women during 26 years. At the beginning of the study, panoramic radiographs were obtained. One observer assessed the trabecular pattern in the premolar region as dense, sparse, or alternating dense and sparse. In addition, on each radiograph, a region of interest was selected in the molar/premolar region and analyzed with texture analysis procedures. During 26years of follow-up, 115 women suffered a fracture of the hip, spine, leg, or arm. Logistic regression was applied to test the predictive power of various variables with respect to fractures.Of all variables, the observer score of the trabecular pattern correlated strongest with the occurrence of fractures. By itself, the score yielded an ROC curve with an area of 0.80 under the curve. Combining the observer score with the texture analysis features increased the area under the ROC curve to 0.85.The trabecular pattern on panoramic radiographs provides a strong predictor of fractures, at least for postmenopausal women. The assessment by an observer combined with texture analysis procedures yields a predictive power that parallels best known predictions in literature.This study illustrates that panoramic radiographs are state of the art predictors of postcranial fractures.

- Objective The aim of the present study was to investigate the reproducibility of bacterial enumeration from subsequent subgingival samples collected from patients with peri-implant mucositis. Material and methods Duplicate microbial samples from 222 unique implant sites in 45 adult subjects were collected with paper points and analyzed using the checkerboard DNA-DNA hybridization technique. Whole genomic probes of 74 preselected bacterial species were used. Based on the bacterial scores, Cohen's kappa coefficient was used to calculate the inter-annotator agreement for categorical data. The percentage agreement was considered as "good" when the two samples showed the same score or differed by 1 to the power of 10. Results Moderate to fair kappa values were displayed for all bacterial species in the test panel (range 0.21-0.58). There were no significant differences between Gram-positive and Gram-negative species. The percentage of good agreement between the first and second samples averaged 74.7 % (n=74; range 56-83 %), while the proportion of poor agreement ranged from 1 to 19 % for the various strains. Conclusion While an acceptable clinical agreement was obtained in most cases, diverging bacterial scores may appear in subgingival samples collected at the same time point from patients with peri-implant mucositis. Clinical relevance The broad bulky base of implant crowns may present an obstacle for the collection of reproducible subgingival samples with paper points.

- OBJECTIVE: Hereditary gelsolin amyloidosis (AGel amyloidosis) is a rare, dominantly inherited systemic disease with worldwide distribution, caused by a gelsolin gene mutation. We studied the periodontal conditions and microbiological plaque composition of AGel amyloidosis patients.MATERIAL AND METHODS: A voluntary study group of 36 AGel amyloidosis patients (mean age 61) filled in a questionnaire. A thorough periodontal examination included periodontal pocket depth and attachment level measurements, registrations of visible plaque, bleeding on probing and panoramic radiographs. The presence of oral Candida was studied by fungal culture method. Bacterial samples from deepened pockets (≥4 mm) were analyzed with checkerboard DNA-DNA hybridization method.RESULTS: VPI (15.3 %) and BOP (11.2 %) of the patients were modest reflecting relatively adequate oral self-care. Still 89 % of the patients had at least one PPD of ≥4 mm; 78.5 % of the PPDs ≥6 mm were found in molars. Patients had lost one third of the molars due to periodontitis and/or tooth decay. Half of the patients (53 %) were Candida carriers. Bacterial analysis of subgingival plaque samples revealed bacterial species common to chronic periodontitis.CONCLUSION: AGel amyloidosis may increase the risk for periodontitis even when the oral self-care is adequate. Molar teeth appear to be mostly affected, leading to tooth loss.CLINICAL RELEVANCE: AGel amyloidosis as a systemic disease is related with a vast variety of symptoms with variable severity. Even though a causal relationship of the systemic disease and periodontitis has not yet been proven, increased risk for periodontal problems should be considered when examining AGel amyloidosis patients.

- Objectives Vitamin D plays an essential role in bone metabo- lism as well as in immunity. Hence, it might affect the devel- opment and extent of periodontal disease. The aim of this study was the assessment of 25-hydroxyvitamin D (25(OH)D) status in periodontal disease. Materials and methods Twenty-nine patients with severe periodontal disease and 29 healthy volunteers were recruited in this case-control-study. Serum 25(OH)D levels, Periodontal Probing Depth (PPD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP), Body Mass Index (BMI), and current smoking status and smoking history (packyears) were assessed in all participants. Serum 25(OH)D levels were com- pared between controls and cases. Multivariable logistic regression was used to determine the odds ratio (OR) and 95 % confidence interval (CI) for periodontal disease in 25(OH)D deficient probands. Results Patients with periodontal disease presented a signifi- cantly higher proportion of deficient 25(OH)D levels (i.e., <50 nmol/l) compared to healthy controls (48 vs. 14 % respec- tively). The adjusted OR for periodontal disease with vitamin D deficiency was 1.5 (95 % CI, 1.13–1.98). No correlation between serum 25(OH)D levels and CAL, PPD, and BOP in the group with periodontal disease was found. Conclusions In this case-control-study 25(OH)D deficiency is significantly associated with periodontal disease. Clinical relevance The assessment of vitamin D levels in pa- tients presenting with periodontal disease seems advisable, as vitamin D deficiency might be involved in the onset and pro- gression of periodontal disease.

- Objective: To systematically review the available histologic evidence on periodontal regeneration in class II and III furcations in animals and humans. Materials and methods: A protocol including all aspects of a systematic review methodology was developed including definition of the focused question, defined search strategy, study inclusion criteria, determination of outcome measures, screening methods, data extraction and analysis, and data synthesis. The focused question was defined as follows: What is the regenerative effect obtained by using or not several biomaterials as adjuncts to open flap surgery in the treatment of periodontal furcation defects as evaluated in animal and human histological studies? Search strategy: Using the MEDLINE database, the literature was searched for articles published up to and including September 2018: combinations of several search terms were applied to identify appropriate studies. Reference lists of review articles and of the included articles in the present review were screened. A hand search of the most important dental journals was also performed. Criteria for study selection and inclusion: Only articles published in English describing animal and human histological studies evaluating the effect of surgical treatment, with or without the adjunctive use of potentially regenerative materials (i.e., barrier membranes, grafting materials, growth factors/proteins, and combinations thereof) for the treatment of periodontal furcation defects were considered. Only studies reporting a minimum of 8weeks healing following reconstructive surgery were included. The primary outcome variable was formation of periodontal supporting tissues [e.g., periodontal ligament, root cementum, and alveolar bone, given as linear measurements (in mm) or as a percentage of the instrumented root length (%)] following surgical treatment with or without regenerative materials, as determined histologically/histomorphometrically. Healing type and defect resolution (i.e., complete regeneration, long junctional epithelium, connective tissue attachment, connective tissue adhesion, or osseous repair) were also recorded. Results: In animals, periodontal regeneration was reported in class II and III defects with open flap debridement alone or combined with various types of bone grafts/bone substitues, biological factors, guided tissue regeneration, and different combinations thereof. The use of biological factors and combination approaches provided the best outcomes for class II defects whereas in class III defects, the combination approaches seem to offer the highest regenerative outcomes. In human class II furcations, the best outcomes were obtained with DFDBA combined with rhPDGF-BB and with GTR. In class III furcations, evidence from two case reports indicated very limited to no periodontal regeneration. Conclusions: Within their limits, the present results suggest that (a) in animals, complete periodontal regeneration has been demonstrated in class II and class III furcation defects, and (b) in humans, the evidence for substantial periodontal regeneration is limited to class II furcations. Clinical relevance: At present, regenerative periodontal surgery represents a valuable treatment option only for human class II furcation defects but not for class III furcations.

- The aim of this study was to analyze the capacity of a new modified laser surface to stimulate calvarial osteoblasts isolated from neonatal mouse bones to differentiate and form mineralized nodules. Titanium discs were subjectezd or not to laser irradiation according to specific parameters and characterized. Osteoblasts isolated from neonatal mouse calvaria were cultured over the discs, and the capacity of these cells to proliferate (MTT assay), form mineralized nodules (Alizarin red assay), and enhance alkaline phosphatase activity (ALPase activity) was analyzed. Real-time PCR was used for quantification of gene expression. Laser-irradiated titanium discs (L) presented a rough nano-to-micrometric oxidized surface contrasting with the smooth pattern on polished discs (P). The R-a on the micrometric level increased from 0.32 +/- 0.01 mu m on P surfaces to 10.57 +/- 0.39 mu m on L surfaces. When compared with P, L promoted changes in osteoblast morphology, increased mineralized nodule formation in osteoblasts cultured on the surfaces for 14 days, and enhanced ALPase activity at days 7 and 14. Transcription factors triggering osteoblast differentiation (Runx2 and Sp7) and genes encoding the bone extracellular matrix proteins collagen type-1 (Col1a1), osteopontin (Spp1), and osteocalcin (Bglap) were upregulated in cells on L surfaces compared with those on P surfaces at days 1-14. Laser treatment of titanium surfaces created a rough surface that stimulated osteoblast differentiation. Laser treatment of titanium generates a reproducible and efficient surface triggering osteoblast differentiation that can be of importance for osteointegration.

- To investigate how heat development in the pulp chamber and coronal surface of natural teeth with and without cusps subjected to irradiance using light-emitting diode (LED)-light-curing units (LCUs) is associated with (i) irradiance, (ii) time, (iii) distance, and (iv) radiant exposure. Three different LED-LCUs were used. Their irradiance was measured with a calibrated spectrometer (BlueLight Analytics Inc., Halifax, Canada). An experimental rig was constructed to control the thermal environment of the teeth. The LED-LCU tip position was accurately controlled by a gantry system. Tooth surface temperature was measured by thermography (ThermaCAM S65 HS, FLIR Systems, Wilsonville, USA) and pulp chamber temperature with a thermocouple. LED-LCU tip distance and irradiation times tested were 0, 2, and 4 mm and 10, 20, and 30 s, respectively. Ethical permission was not required for the use of extracted teeth. Maximum surface and pulp chamber temperatures were recorded in tooth without cusps (58.1 A degrees C +/- 0.9 A degrees C and 43.1 A degrees C +/- 0.9 A degrees C, respectively). Radiant exposure explained the largest amount of variance in temperature, being more affected by time than irradiance. At all combinations of variables tested, repeated measurements produced consistent results indicating the reliability of the method used. Increased exposure time seems to be the factor most likely to cause tissue damage. Risk of superficial tissue damage at irradiances > 1200 mW/cm(2) is evident. There is a risk of pulp damage when only thin dentin is left at higher irradiances (> 1200 mW/cm(2)). Clinicians should be aware of LED-LCU settings and possible high temperature generated.

- Objectives: The aim was to study self-image and the level of psychological symptoms in patients with symptoms attributed to their dental restorative materials.Materials and methods: A questionnaire containing questions regarding dental and medical history was answered by 257 participants, one group with local oral symptoms only (LSO), and one group with multi-symptoms (M-S). A reference group was randomly selected from a research database at the Department of Psychology, Umeå University, Sweden. The self-image was assessed using the Structural Analysis of Social Behavior (SASB). Psychological symptoms such as somatization, depression, and anxiety were assessed using the Symptom Check List 90 (SCL-90) and the Global Severity Index (GSI) was used to determine the level of psychological symptoms.Results: SASB showed that the M-S group and the LSO-group scored significantly higher on the Bspontaneous^ and Bpositive self-image^ than the reference group. In the SCL-90, the M-S group scored significantly higher than the LSO-group and the references on the somatization subscales. On depression, anxiety, and the GSI scale, the M-S group scored significantly higher than the reference group.Conclusions: The two subgroups scored significantly higher on the SASB Spontaneous and Positive clusters which indicates that these patients have an excessively positive self-image, are very spontaneous and have an overconfidence in themselves compared to the reference group. In the M-S group there was a clear tendency to somatization, depression, and anxiety and they were more psychologically stressed than the reference group.Clinical relevance: Among the patients with illness attributed to their dental materials, the M-S-patients had a significantly higher level of general psychological distress and somatization than the control group which may lead to mental stress.

- Objective: This study aims to evaluate the potential association between periodontitis, the number of teeth and cognitive functions in a cohort of older adults in Sweden. Material and methods: In total, 775 individuals from 60 to 99 years of age were selected for the study. A clinical and radiographic examination was performed. The number of teeth and prevalence of periodontal pockets and bone loss was calculated and categorised. Cognitive functions were assessed using the Mini-Mental State Examination (MMSE) and clock test. The education level was obtained from a questionnaire. Data were analysed using chi-square tests and multivariate logistic regression. Results: Age and gender were associated with the prevalence of bone loss. Age and education were associated with lower number of teeth. Gender was also associated with the presence of pockets. The multivariate logistic regression analysis demonstrated a statistically significant association between prevalence of bone loss, the number of teeth and the outcome on MMSE test. This association remained even after adjustment for age, education and gender. Tooth loss was also associated with lower outcome on clock test. Presence of periodontal pockets ≥ 5 mm was not associated with cognitive test outcome. Conclusions: A history of periodontitis and tooth loss may be of importance for cognitive functions among older adults. Clinical relevance: Diseases with and inflammatory profile may have an impact on cognitive decline.

- ObjectiveThe study aims to assess the influence of oral health status and socio-behavioural variables on oral health-related quality of life (OHRQoL) in a sample of Iranian haemodialysis (HD) patients.Materials and methodsThe present case-control study included 512 patients undergoing HD and 255 healthy controls from Iran. A self-reported questionnaire was used to record socio-demographic variables. In addition, laboratory and clinical variables of each patient were extracted from clinical and patient’s electronic records. A closed-ended questionnaire was framed in order to assess oral health knowledge, attitudes and behaviour of each subject. The Short Form Health Survey (SF-36) and Oral Health Impact Profile-14 (OHIP-14) were used respectively to assess general health-related quality of life (GHRQoL) and OHRQoL. All subjects were clinically examined by two trained and experienced dentists for caries by decayed, missing and filled teeth index (DMFT), dental plaque by visible plaque index (VPI), gingival status by Loe and Silness gingival index (GI) and periodontal status by community periodontal index (CPI).ResultsStatistically significant differences were found between HD patients and control subjects for all oral health indices. Patients had significantly (p < 0.001) higher mean DMFT, VPI and GI values than controls. Periodontal pockets deeper than 4 mm were more frequently diagnosed in HD patients (p < 0.001). HD patients reported significantly poorer GHRQoL and also a higher impact of oral health (i.e. poorer OHRQoL) in comparison with the healthy controls (p < 0.01).ConclusionsOral health status, clinical variables, socio-behavioural factors and GHRQoL were significant predictors of OHRQoL in Iranian HD patients.Clinical relevanceThe study findings support the assumption that patient-reported measures can be used to predict treatment need since the objective clinical variables were significantly related to subjective self-reported quality of life in HD patients.

- OBJECTIVES: To evaluate tooth development and calculate dental maturity score in prematurely born children and to compare the findings with full-term born children. MATERIAL AND METHODS: Nine-year-old preterm children were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before week 29), and the other included 38 very preterm children (born during weeks 29 to 32). Panoramic radiography was performed on each child and the preterm children were compared with 42 full-term born children. Five observers independently assessed the tooth development stages for all teeth in the left mandible (31-37) on the panoramic radiographs according to the method described by Demirjian et al. (Hum Biol 45:211-227, 1973). Data from tooth development stages were compiled and converted into a dental maturity score for each group. Kappa values were calculated for intra- and inter-observer agreement. RESULTS: When the different development stages for each individual tooth were compared, all observers presented a significant delay in the maturity of tooth 37 for the extremely preterm group (p

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: The aims were to assess the impact of the number of years since dentists' graduation on appraisement of diagnostic needs and utilization of treatment options for temporomandibular disorders (TMD) and to investigate whether increased knowledge in TMD is sufficiently considered in today's dentist's undergraduate curricula and, therefore, represented in more evidence-based TMD management in dentists with less years since graduation. MATERIAL AND METHODS: A questionnaire regarding knowledge and management of TMD was developed and was subsequently applied in a random sample of 400 dentists in a region in Northern Germany. RESULTS: Of the 222 dentists (response rate 55.6 %), participating in the study, the frequency of TMD treatment need in the general population was estimated at 21.5 %, with lower values in dentists with more years passed since graduation. Measures regarding utilization of standardized examination forms, perceptions of insufficient specialization, and referrals of patients to TMD specialists indicated a lower quality and certainty in TMD management in participants with less time since graduation. While the provision of splints was a well-established treatment option in initial TMD management of all participants, additional TMD treatment options were mentioned less often, with lower proportions of participants making use of these options within the first decade since graduation. CONCLUSIONS: Evidence-based TMD management is not fully represented in dental practitioners in Germany. This might be due to an insufficient consideration of TMD management in the dentist's undergraduate curricula. CLINICAL RELEVANCE: Effective interventions to increase dentists' knowledge and to change dentists' practices in TMD management are required.

- OBJECTIVES: This study aims to assess mortality risk and its association to health aspects in dentate individuals 60 years of age and older.MATERIALS AND METHODS: Medical and periodontal data from 870 dentate individuals (age range 60-96) participating in the Swedish National Study on Aging and Care in Blekinge (SNAC-Blekinge) with survival statistics over 6 years were studied.RESULTS: During 6 years of follow-up, 42/474 of the individuals (8.9 %), who at baseline were between age 60 and 75, and 134/396 individuals of the individuals (33.9 %), who at baseline were ≥75 years, died. Surviving dentate individuals had more teeth (mean 19.3, S.D. ± 7.9) than those who died (mean 15.9, S.D. ± 7.3; mean diff 3,3; S.E. mean diff 0.7; 95 % CI 2.0, 4.6; p = 0.001). A self-reported history of high blood pressure (F = 15.0, p < 0.001), heart failure (F = 24.5, p < 0.001, observed power = 0.99), older age (F = 34.7, p < 0.001), male gender (F = 6.3, p < 0.01), serum HbA1c with 6.5 % as cutoff level (F = 9.3, p = 0.002) were factors associated with mortality. A medical diagnosis of heart disease, diabetes, any form of cancer, or periodontitis failed to predict mortality.CONCLUSIONS: A self-reported history of angina pectoris, chronic heart failure, elevated serum HbA1c, and few remaining teeth were associated with mortality risk. A professional diagnosis of cardiovascular disease, diabetes, cancer, or periodontitis was not predictive of mortality.CLINICAL RELEVANCE: Self-health reports are important to observe in the assessment of disease and survival in older individual.

- OBJECTIVES:Biomaterial surfaces are at high risk for initial microbial colonization, persistence, and concomitant infection. The rationale of this study was to assess the initial adhesion on novel implant surfaces of Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans upon incubation.MATERIALS AND METHODS:The tested samples were 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) samples with nitrogen-doped hydrogenated amorphous carbon (a-C:H:N) coating (A) and 3Y-TZP samples coated with ceria-stabilized zirconia-based (Ce-TZP) composite and a-C:H:N (B). Uncoated 3Y-TZP samples (C) and bovine enamel slabs (BES) served as controls. Once the surface was characterized, the adherent microorganisms were quantified by estimating the colony-forming units (CFUs). Microbial vitality was assessed by live/dead staining, and microbial-biomaterial surface topography was visualized by scanning electron microscopy (SEM).RESULTS:Overall, A and B presented the lowest CFU values for all microorganisms, while C sheltered significantly less E. faecalis, P. aeruginosa, and C. albicans than BES. Compared to the controls, B demonstrated the lowest vitality values for E. coli (54.12 %) and C. albicans (67.99 %). Interestingly, A (29.24 %) exhibited higher eradication rates for S. aureus than B (13.95 %).CONCLUSIONS:Within the limitations of this study, a-C:H:N-coated 3Y-TZP surfaces tended to harbor less initially adherent microorganisms and selectively interfered with their vitality.CLINICAL RELEVANCE:This could enable further investigation of the new multi-functional zirconia surfaces to confirm their favorable antimicrobial properties in vivo.

- OBJECTIVES: The objectives of this study were to assess orofacial profiles in 5- and 10-year-old children with cleft lip and/or palate (CL/P) compared to controls and to estimate a possible association between orofacial dysfunction and caries frequency.MATERIALS AND METHODS: A total of 133 children with CL/P (77 5-year-olds and 56 10-year-olds) and 308 controls (142 5-year-olds and 166 10-year-olds) were included in the study. Orofacial function was evaluated with Nordic Orofacial Test-Screening (NOT-S), and caries were scored according to the International Caries Detection and Assessment System (ICDAS).RESULTS: The total NOT-S score was higher in children with CL/P compared to controls (mean 3.2 vs 0.9, p < 0.001). The domains frequently scored in CL/P children were speech (82%), face at rest (72%), and facial expression (58%). There was a significantly positive correlation between NOT-S scores and caries frequency.CONCLUSIONS: Children with CL/P have impaired orofacial function compared to controls. There seems to be a correlation between orofacial function and caries.CLINICAL RELEVANCE: Impaired orofacial function seen in children with CL/P can be one of many risk factors for caries development, and it is suggested to be a part of caries risk assessment.

- Objective The aim of this study is to evaluate, in a randomized controlled cross-over study, the effect of daily intake of the alga Ascophyllum nodosum on supragingival calculus, plaque formation, and gingival health over a 6-month period. Material and methods Sixty-one adults with moderate to heavy calculus formation since their last yearly recall visit participated. In a randomized order over two 6-month periods, they swallowed two capsules daily, comprising a total of 500 mg dried marine alga powder (Ascophyllum nodosum, ProDen PlaqueOff (R)) or two negative control tablets. During the study, the participants maintained their regular oral habits. Their teeth were professionally cleaned at the start of each period and after the 6-month registrations. Awash out period of 1 month separated the two 6-month periods. Supragingival calculus (VolpeManhold), gingivitis (Loe and Silness), gingival bleeding (Ainamo and Bay), and plaque (Quigley-Hein) were registered at screening and at the end of the two periods. Differences in oral health between the test and control periods were analyzed using a paired t test and Wilcoxon signed rank test. Results Fifty-five participants completed the study. After the alga intake, the mean calculus reduction was 52% compared to the control (p<0.0001). Fifty-two participants showed less calculus formation in the alga group than in the control group. Plaque (p=0.008) and gingival bleeding (p=0.02) were also significantly less in the alga group. However, no significant difference was found between the groups for gingivitis (p=0.13). Conclusions The alga intake significantly reduced the formation of supragingival calculus and plaque and occurrence of gingival bleeding. The alga has a systemic effect on oral health. Clinical relevance Daily intake of the alga Ascophyllum nodosum as an adjunct to customary oral hygiene showed a major reduction of supragingival calculus formation and reduced plaque formation. In addition, the calculus in the alga group was characterized by a more porous and less solid structure and was easier to remove than the calculus in the control group.

- OBJECTIVES: The aim of this study is to observe the durability of Class II nanohybrid resin composite restorations, placed with two different adhesive systems, in an 8-year follow-up.METHODS: Seventy-eight participants received at random at least two Class II restorations of the ormocer-based nanohybrid resin composite (Ceram X) bonded with either a one-step self-etch adhesive (Xeno III) or a control two-step etch-and-rinse adhesive (Excite). The 165 restorations were evaluated using slightly modified United States Public Health Services (USPHS) criteria at baseline and then yearly during 8 years.RESULTS: One hundred and fifty-eight restorations were evaluated after 8 years. Three participants with five restorations (three Xeno III, two Excite) were registered as dropouts. Twenty-one failed restorations (13.3 %) were observed during the follow-up. Twelve in the one-step self-etch adhesive group (13.5 %) and nine in the two-step etch-and-rinse group (13.0 %). This resulted in nonsignificant different annual failure rates of 1.69 and 1.63 %, respectively. Fracture of restoration was the main reason for failure.CONCLUSION: Good clinical performance was shown during the 8-year evaluation and no significant difference in overall clinical performance between the two adhesives. Fracture was the main reason for failure.CLINICAL RELEVANCE: The one-step self-etch adhesive showed a good long-term clinical effectiveness in combination with the nanohybrid resin composite in Class II restorations.

- Objectives Medication-induced salivary gland dysfunction (MISGD) causes significant morbidity resulting in decreased quality of life. This systematic review assessed the literature on the prevalence, diagnosis, treatment, and prevention of MISGD. Materials and methods Electronic databases were searched for articles related to MISGD through June 2013. Four independent reviewers extracted information regarding study design, study population, interventions, outcomes, and conclusions for each article. Only papers with acceptable degree of relevance, quality of methodology, and strength of evidence were retained for further analysis. Results There were limited data on the epidemiology of MISGD. Furthermore, various methods were used to assess salivary flow rate or xerostomia. Preventive and therapeutic strategies included substitution of medications, oral, or systemic therapy with sialogogues, use of saliva substitutes or of electro-stimulating devices. Although there are promising approaches to improve salivary gland function, most studies are characterized by small numbers and heterogeneous methods. Conclusions Physicians and dentists should identify the medications associated with xerostomia and salivary gland dysfunction through a thorough medical history. Preferably, health care providers should measure the unstimulated and stimulated whole salivary flow rates of all their patients so that these values can be used as a baseline to rate the complaints of patients who subsequently claim to experience xerostomia or salivary gland dysfunction as well as the possibilities of effectively treating this condition. Clinical relevance MISGD remains a major burden for the population. This systematic review provides a contemporary in-depth description of the diagnosis and treatment of MISGD.

- The aim of the present investigation was to study if there is a reduced clinical effect and fluoride retention of a mouthrinse solution containing both chlorhexidine (CHX) and sodium fluoride (NaF). Two clinical trials were designed as double-blind, randomized, cross-over studies. In study I, 16 healthy subjects were asked to rinse twice daily for 1 min during 4 days of no tooth brushing with four solutions: (1) 0.12% CHX + 0.2% NaF, (2) 0.2% NaF, (3) 0.12% CHX, and (4) placebo. In study II, another 16 healthy subjects rinsed with the same four solutions twice daily after tooth brushing during a 6-week period. Plaque formation, gingivitis, and microbiological samples from plaque and saliva, as well as fluoride retention, were analyzed. Both studies showed that both CHX + NaF and CHX mouthrinses had the same clinical effect with regards to plaque formation and microflora in plaque and saliva. Similarly, fluoride retention was not altered by the CHX + NaF mouthrinse compared to the NaF solution. The combination of CHX and NaF in a mouthrinse showed the same clinical effect as the CHX solution. The retention of fluoride in the oral cavity was not affected by the combination of NaF and CHX. A mouthrinse solution containing a mixture of CHX and NaF may be an interesting product for risk patients for caries and periodontal disease. However, this should be verified in further long-term clinical studies.

- OBJECTIVES: Aims were to investigate and compare the validity and reliability of Oral Health Impact Profile (OHIP) scores referencing 7-day and 1-month recall periods in international prosthodontic patients.MATERIAL AND METHODS: A sample of 267 patients (mean age = 54.0 years, SD = 17.2 years, 58 % women) with stable oral health-related quality of life was recruited from prosthodontic treatment centers in Croatia, Germany, Hungary, Japan, Slovenia, and Sweden. These patients completed the OHIP on two occasions using a new 7-day recall period and the traditional 1-month recall period. OHIP score validity and reliability were investigated with structural equation models (SEMs) that included OHIP(past 7 days) and OHIP(1 month) latent factors and single indicator measures of global oral health status. The SEMs assessed measurement invariance and the relative validities of the two OHIP latent factors (representing the two recall periods).RESULTS: The SEMs provided cogent evidence for recall period measurement invariance for the two OHIP forms and equal validities (r = .48) with external measures of global oral health status.CONCLUSION: When assessed in international prosthodontic patients, OHIP scores using the new 7-day recall period were as reliable and valid as the scores using the 1-month recall period.CLINICAL RELEVANCE: Conceptual advantages make a 7-day recall period a preferred frame of reference in clinical applications of the OHIP questionnaire.

- OBJECTIVE: To assess if carotid calcifications detected in panoramic radiographs are associated with future events of stroke, and/or ischemic heart diseases over 10-13 years in individuals between 60 and 96 years.MATERIALS AND METHODS: Baseline (2001-2004) panoramic radiographs were assessed for evidence of carotid calcifications from individuals with no previous history of stroke and/or ischemic heart diseases. A radiopaque nodular mass adjacent to the cervical vertebrae, at or below the intervertebral space C3-C4, was interpreted as carotid calcification. Annual medical records were searched for ICD 10 codes through 2014.RESULTS: Signs of carotid calcification was demonstrated in 238/635 (37.5%) of the study individuals. Signs of carotid calcification was associated with future stroke and/or ischemic heart diseases (χ2 = 9.1, OR 1.6, 95% CI 1.2, 2.2, p < 0.002). In individuals 60-72 years, a significant association between radiographic signs of carotid calcification and stroke and/or ischemic heart diseases (χ2 = 12.4, OR 2.4, 95% CI 1.5, 4.0, p < 0.000) (adjusted for high blood pressure, diabetes type 2, BMI; OR 1.9, 95% CI 1.1, 3.5, p = 0.03). Individuals (60-72 years) with radiographic evidence of carotid calcifications had a mean cumulative stroke and/or ischemic heart diseases survival time of 12.1 years compared to those without such evidence (13.0 years) (log rank Mantel-Cox χ2 = 10.7, p = 0.001).CONCLUSIONS: Evidence of carotid calcifications in panoramic radiographs is associated with an event of stroke and/or ischemic heart diseases in 60-96-year-old individuals.CLINICAL RELEVANCE: Radiographic evidence of carotid calcifications is associated with stroke and/or ischemic heart diseases. Patients with signs of carotid calcifications should therefore be referred for medical examination.

- Objectives The aetiology of recurrent aphthous stomatitis remains unknown. In this study, we investigate the composition of oligosaccharides from mucin MUC7 in recurrent aphthous stomatitis as these heavily O-glycosylated mucins confer many of saliva's protective properties such as defence against mucosal pathogens. Materials and methods Unstimulated whole saliva samples were collected from six individuals, three with recurrent aphthous stomatitis and three corresponding sibling, without this condition. Oligosaccharides from salivary MUC7 were isolated and analysed by liquid chromatography-tandem mass spectrometry. Results The types of oligosaccharides identified in the patients and control subjects were similar; however, statistical evaluation indicated semi-quantitative differences between specific oligosaccharide classes. These changes focused on a reduction in terminal glycan residues including fucosylation, sialylation and sulfation on galactose. Conclusions This study was able to show differential MUC7 glycosylation in the patients suggesting functional changes to salivary mucins in this condition. The terminal glycans altered in disease have been shown to be important for a range of immunological and bacterial binding roles. Further investigation of these epitopes in a larger study may provide critical insights into the pathology of recurrent aphthous stomatitis. Clinical relevance MUC7 glycosylation is altered in recurrent aphthous stomatitis. This may change the protective properties of this mucin against mucosal pathogens, which may effect this condition.
