- Background To achieve good and equal oral health in children, interdisciplinary preventive oral health actions, directed toward disadvantaged areas, can be an important means. Staff play a crucial role in the implementation of these actions. The aim of the present study was to analyze circumstances of importance for conducting an interdisciplinary public preventive oral health project for children, directed toward parents in areas with low socioeconomic status from the interdisciplinary perspective of the involved staff. Method The present study consisted of a qualitative content analysis with an inductive approach, based on interviews with interdisciplinary staff who had participated in a public preventive oral health project directed toward parents in areas with low socioeconomic status. The interviews were analyzed using text-driven analysis. Results The main category concerned the staff members prerequisites and understanding necessary to perform their tasks in interdisciplinary public preventive oral health project. To have the right prerequisites and understanding regarding the oral health project enabled staff to be committed, able and willing to perform in it. Important aspects of this are to have knowledge, motivation and to experience a supportive professional context, to have good leadership and for certain resources to fulfilled. A crucial aspect was to reach the targeted mothers. Conclusions For interdisciplinary cooperation in preventive oral health care to be achieved, it is essential for the involved disciplines and professions to embrace a common view on the projects aim, their duties, and oral health, from the leadership to the individual level. Staff require competent leadership but also allocated time and adapted method support to be successful in this context. When allocating preventive health actions directed at low SES areas, it is important to acknowledge the risk of stigmatization and for staff to understand that families might be facing social challenges that prevent them from taking part in health-promoting actions. An important conclusion is that to be able to reach people, it is important for both those who design preventive programs for oral health and the staff who administer them to have sufficient knowledge about the target group.

- Background The aim of the study was to describe prevalence, severity and distribution of periodontal disease as well as associated risk factors in an indigenous Sami population in Northern Norway, and to investigate differences between the indigenous Sami and the non-Sami population. Methods This cross-sectional study included data from the Dental Health in the North study (N = 2078; 18-75 years). Data on Ethnicity, household income, education, smoking habits, dental attendance, and tooth brushing habits were collected by a questionnaire. Periodontal conditions were assessed by clinical examination. A modified version of the new AAP/EFP classification system of periodontal disease was used to estimate the severity of periodontitis. Three stages were used: 'Non-severe periodontitis', 'Stage II', and stage 'III/IV'. Results Of the total study population 66.5% reported Sami affiliation. The total prevalence of periodontitis was 49.7%, with 20.1% in Stage III/IV, but no differences between Sami and non-Sami. When controlled for sex, age, education, smoking and dental attendance the Sami had higher probability of having more severe stages of periodontitis; Odds Ratio(Stage II) (OR) = 1.3; 95% CI: 1.1-1.7; and ORStage III/IV (OR) = 1.6; 95% CI: 1.1-2.2) compared to non-Sami. The Sami had higher prevalence of periodontal pocket depth (PD) >= 4 mm (t = 1.77; p < 0.001) and PD >= 6 mm (t = 1.08; p = 0.038) than the non-Sami. Conclusions The prevalence of periodontitis was high in communities in the core area of Sami settlement in Northern Norway, regardless of ethnicity. People with Sami ethnicity had more deep periodontal pockets and an increased odds of having severe stages of periodontitis. Future studies should address possible explaining factors behind the potential higher risk of having more severe periodontitis among indigenous people in Sami settlements.

- BackgroundTooth decay and periodontal diseases are the main oral pathologies in the world. The prevalence of overweight in children has increased worldwide. Overweight children have alterations in the composition of saliva and excessive consumption of saturated fatty acids tend to slow the metabolism of carbohydrates in the oral cavity leading to tooth decay, periodontal disease and others oral disorders. The aim of this study was to assess the relationship between oral pathologies and overweight in pupils of primary schools of Cameroon.MethodsA cross-sectional study was carried out from June to August 2020 in four government primary schools selected through cluster sampling in Yaounde. 650 pupils aged between 6 and 11 years were enrolled. Data collected included anthropometric, oral pathologies, quality of oral hygiene and feeding habits. Data were analysed with the SPSS 26.0 statistical software and binary logistic regression was used to determine the risks of oral pathologies in overweight pupils. P-value of 0.05 was considered statistically significant.ResultsThe prevalence of overweight was 27% (95% CI: 23.5-30.5). The main oral pathologies was tooth decay (60.3%). Binary logistic regression revealed that overweight pupils were significantly 1.5 times more likely to develop tooth decay than non-overweight pupils (95% CI: 1.1-2.4).ConclusionOverweight, tooth decay are prevalent among pupils. Overweight pupils have a higher risk of developing tooth decay compared to non-obese pupils. An integrated package of oral and nutritional health promotion activities is necessary in primary schools in Cameroon.

- BACKGROUND: To evaluate oral health-related quality of life (OHRQoL) over a period of five years using the Oral Health Impact Profile (OHIP-14) questionnaire in a population of Swedish adolescents born preterm and full term.METHODS: In a longitudinal study of adolescents aged 12-14 and 17-19, changes over time in OHRQoL were measured by using OHIP-14. The OHIP-14 score, self-reported chronic illness, temporomandibular disorder (TMD pain) and subjective orthodontic treatment need were compared between 98 extremely and very preterm born (< 32 gestational week) and 93 full-term controls (≥ 37 gestational week) at two ages. The chi-square test was used for comparisons within the extremely-, very-, and full-term control groups, and to contrast the differences of mean scores of OHIP-14, the ANOVA test was used for comparisons within the study groups of extremely preterm, very preterm and full term-born adolescents.RESULTS: All adolescents reported a good self-perceived OHRQoL. No significant differences in the comparisons of the total mean scores were revealed between the groups, between gender or in domain-specific scores over the 5-year period. Very preterm adolescents with reported chronic illness at 12-14 years of age showed significantly higher mean scores of OHIP-14 compared with those without chronic illness (p = 0.015). At age 17-19, significantly higher mean scores of OHIP-14 were reported by very preterm adolescents with TMD pain compared to those without TMD pain (p = 0.024). Significantly higher mean scores of OHIP-14 were found among the extremely preterm (p = 0.011) and very preterm born adolescents (p = 0.031) with a subjective need of orthodontic treatment compared with those without orthodontic treatment need.CONCLUSIONS: Poor OHRQoL measured with OHIP-14 in very preterm adolescents aged 12-14 was related to chronic illness and aged 17-19 to TMD pain. In addition, extremely and very preterm-born adolescents with subjective orthodontic treatment need at 17-19 years of age also reported poor OHRQoL. To improve the dentist-patient relationship and achieve more successful treatment results, it is important for dental clinicians to understand the impact that chronic illness, TMD pain and orthodontic treatment need has on OHRQoL in preterm-born adolescents.

Forskningsöversikt (refereegranskat)abstract
- Epidemiological data from countries worldwide show a consistent pattern implying that a fraction of around 10% of those over 40-50years in all populations will exhibit severe periodontitis with the potential risk of losing teeth during their life-time. The subgingival microbiota shows striking similarities between populations irrespective of disease severity and can only marginally explain the clinical pattern. It is also difficult to explain this pattern by genetic and acquired risk factors such as systemic disease (e.g. diabetes) or habits (e.g. smoking) even if they may have a confounding effect on the disease.Inflammation of the gingiva appears to be a normal and physiological response to the presence of commensal bacteria along the gingival crevice and in the dental biofilm. Over many years of exposure to the dental biofilm, the chronic inflammation in the gingiva gradually results in a loss of attachment and bone loss. Numerous laboratory and clinical studies have provided insight into the potential role of determinants that are associated with periodontitis. However, it has been difficult to relate the findings to the pattern of the distribution of the disease observed in epidemiological studies. We propose a simple and parsimonious model that considers all the multitude of potential determinants as creating effectively random noise within the dental biofilm to which the tissues react by accumulating the effects of this noise.We suggest that such a model can explain many of the epidemiological features of periodontal breakdown over time, and we discuss its clinical implications.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Dysbiosis in subgingival microbial communities, resulting from increased inflammatory transudate from the gingival tissues, is an important factor in initiation and development of periodontitis. Dysbiotic communities are characterized by increased numbers of bacteria that exploit the serum-like transudate for nutrients, giving rise to a proteolytic community phenotype. Here we investigate the contribution of interactions between members of a sub-gingival community to survival and development of virulence in a serum environment-modelling that in the subgingival pocket.METHODS: Growth and proteolytic activity of three Porphyromonas gingivalis strains in nutrient broth or a serum environment were assessed using A600 and a fluorescent protease substrate, respectively. Adherence of P. gingivalis strains to serum-coated surfaces was studied with confocal microscopy and 2D-gel electrophoresis of bacterial supernatants used to investigate extracellular proteins. A model multi-species sub-gingival community containing Fusobacterium nucleatum, Streptococcus constellatus, Parvimonas micra with wild type or isogenic mutants of P. gingivalis was then created and growth and proteolytic activity in serum assessed as above. Community composition over time was monitored using culture techniques and qPCR.RESULTS: The P. gingivalis strains showed different growth rates in nutrient broth related to the level of proteolytic activity (largely gingipains) in the cultures. Despite being able to adhere to serum-coated surfaces, none of the strains was able to grow alone in a serum environment. Together in the subgingival consortium however, all the included species were able to grow in the serum environment and the community adopted a proteolytic phenotype. Inclusion of P. gingivalis strains lacking gingipains in the consortium revealed that community growth was facilitated by Rgp gingipain from P. gingivalis.CONCLUSIONS: In the multi-species consortium, growth was facilitated by the wild-type and Rgp-expressing strains of P. gingivalis, suggesting that Rgp is involved in delivery of nutrients to the whole community through degradation of complex protein substrates in serum. Whereas they are constitutively expressed by P. gingivalis in nutrient broth, gingipain expression in the model periodontal pocket environment (serum) appeared to be orchestrated through signaling to P. gingivalis from other members of the community, a phenomenon which then promoted growth of the whole community.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: To analyse via life cycle analysis (LCA) the global resource use and environmental output of the endodontic procedure.METHODOLOGY: An LCA was conducted to measure the life cycle of a standard/routine two-visit RCT. The LCA was conducted according to the International Organization of Standardization guidelines; ISO 14040:2006. All clinical elements of an endodontic treatment (RCT) were input into OpenLCA software using process and flows from the ecoinvent database. Travel to and from the dental clinic was not included. Environmental outputs included abiotic depletion, acidification, freshwater ecotoxicity/eutrophication, human toxicity, cancer/non cancer effects, ionizing radiation, global warming, marine eutrophication, ozone depletion, photochemical ozone formation and terrestrial eutrophication.RESULTS: An RCT procedure contributes 4.9 kg of carbon dioxide equivalent (CO2 eq) emissions. This is the equivalent of a 30 km drive in a small car. The main 5 contributors were dental clothing followed by surface disinfection (isopropanol), disposable bib (paper and plastic), single-use stainless steel instruments and electricity use. Although this LCA has illustrated the effect endodontic treatment has on the environment, there are a number of limitations that may influence the validity of the results.CONCLUSIONS: The endodontic team need to consider how they can reduce the environmental burden of endodontic care. One immediate area of focus might be to consider alternatives to isopropyl alcohol, and look at paper, single use instrument and electricity use. Longer term, research into environmentally-friendly medicaments should continue to investigate the replacement of current cytotoxic gold standards with possible natural alternatives. Minimally invasive regenerative endodontics techniques designed to stimulate repair or regeneration of damaged pulp tissue may also be one way of improving the environmental impact of an RCT.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThis study aimed to increase the understanding of emotions and coping strategies used by head and neck cancer patients before cancer treatment, and to explore their emotions and coping strategies in relation to symptoms and side effects after treatment. Furthermore, we aimed to investigate the patients' perceptions of received treatment and support.MethodsSemi-structured in-depth interviews were conducted with 10 patients who had been treated for head and neck cancer, which included radiotherapy, at the Department of Oncology and the Department of Oral and Maxillofacial Surgery at Sahlgrenska University Hospital in Gothenburg. The interviews were analyzed in accordance with the method for Qualitative Content Analysis.ResultsThe result picture revealed three head themes. The first theme "Management of simultaneously influencing mind-sets before cancer treatment" described the patients experiences of feeling "Scared and worried," "Lonely and disappointed," and "Relieved and confident", and how they tried to handle the diagnosis and preparations for treatment by "Applying a positive mind-set", "Searching for support," and "Trusting the healthcare system". The second theme "Experiences of becoming a pale shadow of oneself", illustrated experiences of affecting post-treatment symptoms and side effects. To which, the last theme "Handling contextual influencing experiences after cancer treatment" displayed post-treatment emotions of being "Shocked and disappointed" and "Concerned and unsupported" but also "Grateful and forward-thinking", where strategies such as "Appreciating Life", "Networking socially," and "Adapting to the new life" were used.ConclusionsThe results indicated the need for a more patient-centered care approach, with clearer structures and improved individual support both before and after treatment and in connection to rehabilitation. Patients' cognitive changes after cancer treatment should be considered in the aftercare, which should also include adaptation to situation and strengthening of patients' self-management as a goal.

- BackgroundThe effect of rapid maxillary expansion (RME) on the upper airway (UA) has been studied earlier but without a consistent conclusion. This study aims to evaluate the outcome of RME on the UA function in terms of aerodynamic characteristics by applying a computational fluid dynamics (CFD) simulation.MethodsThis retrospective cohort study consists of seventeen cases with two consecutive CBCT scans obtained before (T0) and after (T1) RME. Patients were divided into two groups with respect to patency of the nasopharyngeal airway as expressed in the adenoidal nasopharyngeal ratio (AN): group 1 was comprised of patients with an AN ratio<0.6 and group 2 encompassing those with an AN ratio0.6. CFD simulation at inspiration and expiration were performed based on the three-dimensional (3D) models of the UA segmented from the CBCT images. The aerodynamic characteristics in terms of pressure drop (Delta P), maximum midsagittal velocity (V-ms), and maximum wall shear stress (P-ws) were compared by paired t-test and Wilcoxon test according to the normality test at T0 and T1.ResultsThe aerodynamic characteristics in UA revealed no statistically significant difference after RME. The maximum V-ms (m/s) decreased from 2.79 to 2.28 at expiration after RME (P=0.057).ConclusionThe aerodynamic characteristics were not significantly changed after RME. Further CFD studies with more cases are warranted.

- Background Children and adolescents with juvenile idiopathic arthritis (JIA) may suffer from temporomandibular disorder (TMD). Due to this, imaging diagnosis is crucial in JIA with non-symptomatic TM joint (TMJ) involvement. The aim of the study was to examine the association between clinical TMD signs/symptoms and cone-beam computed tomography (CBCT) findings of TMJ structural deformities in children and adolescents with JIA. Methods This cross-sectional study is part of a longitudinal prospective multi-centre study performed from 2015-2020, including 228 children and adolescents aged 4-16 years diagnosed with JIA, according to the International League of Associations for Rheumatology (ILAR). For this sub-study, we included the Bergen cohort of 72 patients (32 female, median age 13.1 years, median duration of JIA 4.5 years). Clinical TMD signs/symptoms were registered as pain on palpation, pain on jaw movement, and combined pain of those two. The severity of TMJ deformity was classified as sound (no deformity), mild, or moderate/severe according to the radiographic findings of CBCT. Results Of 72 patients, 21 (29.2%) had pain on palpation at and around the lateral pole, while 41 (56.9%) had TMJ pain upon jaw movement and 26 (36.1%) had pain from both. Of 141 TMJs, 18.4% had mild and 14.2% had moderate/severe structural deformities visible on CBCT. CBCT findings were not significantly associated with either the pain on palpation or the pain on jaw movement. A significant difference was found between structural deformities in CBCT and the combined pain outcome (pain at both palpation and movement) for both TMJs for the persistent oligoarticular subtype (p = 0.031). Conclusions There was no association between painful TMD and CBCT imaging features of the TMJ in patients with JIA, but the oligoarticular subtype of JIA, there was a significant difference associated with TMJ pain and structural CBCT deformities.
