- The aim of the this study was to present data on oral care habits and knowledge of oral health in 2013, and to compare these data with results from a series of four previous cross-sectional epidemiological studies. All these studies were carried out in the city ofionkoping, Sweden, in 1973,1983,1993, 2003, and 2o13.The 1973 study constituted a random sample of L000 individuals evenly distributed in the age groups 3, 5,10,15, 20, 30,40, 50, 6o, and 7o yea rs.The same age groups with addition of a group of 8o-year-olds were included in the 1983,1993, 2003, and 2013 studies, which comprised 1,104;1,078; 987; and 1,010 individuals, respectively. A questionnaire about dental care habits and knowledge of oral health was used. The questionnaire contained the same questions in all the five studies, although some had to be slightly modernised during the 40-year period. During the period 1973-2013, a continous increase of individuals in the age group 20-6o years were treated by the Public Dental Service amounting to about 5o%. Almost 7o% of the 70- and 80-year-olds were treated by private practitioners. In 2013,10-20% of the individuals in the age groups 30-40 years did not regularly visit neither Public Dental Service nor a private practitioner.The corresponding figures for the individuals 50-80 years old were 4-7%. Similar number of avoidance was reported in the previous studies. In the survey 2013, about 20-30% of the individuals in the age groups 20-50 felt frightened, sick, or ill at ease at the prospect of an appointment with the dentist.These findings were in agreement with the results from the surveys 1973-2003. Among the younger age groups, 10-15 years, a reduction in self-reported "ill at ease" was found in the surveys 2003 and 2013 compared to the previous surveys in this series. In 2013, the knowledge of the etiology of caries was known by about 6o% of the individuals which was similar to that reported 1973 zoo3.Twenty per cent of the individuals stated that they did not know which etiological factors that causes caries.This percentage was equivalent during the period 1973-2013. About 85% of the individuals in all age groups brushed their teeth with fluoride tooth paste at least two times a day.These frequencies have gradually increased during the 40-year period. Around 40% in the age groups 50-8o years used toothpicks regularly in 2013.This is a about 1/3-1/2 less compared to 2003. In the age groups 20-40 years 3-14% used toothpicks for proximal cleaning in 2013. In 2013, about 35% of the individuals never consumed soft drinks, in comparison with 20% in 2003. In the age groups 3-20 years about 20% were consuming soft drinks every day or several times a week, which is a reduction by half compared to 2013

- The aim of this epidemiological study performed in 2013 was to analyze various clinical and radiographic data on oral health and compare the results to those of four cross-sectional studies carried out 1973-2003. In 1973,1983,1993,2003, and 2013 random samples of 1,000;1,104;1,078; 987; and 1,010 individuals, respectively, were studied. The individuals were evenly distributed in the age groups 3,5,10,15, 20,30,40,50, 60,70, and 8o years. Eighty-year-olds were not included in 1973. All subjects were inhabitants of the city of Jonkoping, Sweden.The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations, oral hygiene, calculus, periodontal status, and endodontic treatment.The frequency of edentulous individuals aged 40-70 years was 16,12, 8,1, and 0.3% in 1973,1983,1993, 2003, and 2013, respectively. No complete denture wearer younger than 80-years old was found in 2013. During the 40-year period, the mean number of teeth in the age groups 30-80 years increased. In 2013, the 60-year-olds had nearly complete dentitions. Implants were found in all age groups from 30 years of age. The total number of individuals with implants was 36 in 2013.This was higher than earlier surveys,4 in 1993, and 18 in 2003.The percentage of children and adults without caries and restorations increased during the 40-year period. It was found that the percentage of caries-free 3- and 5-year-olds were 79% and 69%, respectively, of the individuals in 2013. In the age groups 10-20 years, the percentage of caries-free individuals increased between 2003 and 2013. In 2013,43% of the 15-year-olds were completely free from caries and restorations compared to 20% in 2003. In all age groups 5-60 years, DFS was lower in 2013 compared to the earlier examinations. There was no major change in DFS between 2003 and 2013 in the age groups 70 and 80 years. The most obvious change was the decrease in number of FS over the 40 year period of time. Regarding crowned teeth the most clear changes between 1973 to 2013 were the decrease in percentage of crowned teeth in the age goups 4o and 50-year-olds. The percentage of endodontically treated teeth decreased between 1973 and 2013 in all age groups.In age groups-Jo-30-year-olds a major reduction from about 3o% to 15% in mean plaque score was seen between 1973-2003. Only a minor change in plaque score was seen during the last decade. For the age groups 40 years and older, a decrease in the percentage of surfaces with plaque was observed between 2003-2o13.The percentage of tooth sites with gingivitis was for zo years and older about 4o% in 1973. In 2013, the percentage was about15%. The frequency of sites with gingivitis was generally lower in 2013 compared with the other years:1973-1993.The percentage of individuals with probing pocket depths >4mm increased with age. Between 2003-2013 a clear reduction was seen in all age groups in frequency of individuals with probing pocket depth >4mm. Over the 40-year period an increase in the number of individuals with no marginal bone loss and a decrease in the number of subjects with moderate alveolar bone loss were seen.The continuous improvement in oral health and the reduced need of restorative treatment will seriously affect the provision of dental helath care and dental delivery system in the near future.

A randomized controlled cross-over study of the effect of alcohol-free chlorhexidine and essential oils on interleukin-1 levels in crevicular fluid
- 2016
-
In: Swedish Dental Journal. - 0347-9994. ; 40:2, s. 143-152

Journal article (peer-reviewed)abstract
- Aim of the study was to determine the effect of an alcohol-free chlorhexidine mouth rinse and an essential oils containing mouth rinse on pro-inflammatory cytokine levels in gingival crevicular fluid in participants who continue to perform their regular mechanical oral hygiene regimes and normal dietary practice. Twenty adult volunteers (mean age: 59 years) participated in the double-blind randomised controlled cross-over study. Three mouth rinses were used during 16-day periods as an adjunctive to regular mechanical oral hygiene: a solution with alcohol-free chlorhexidine (CHX; Paroex (R)), a solution with essential oils (EO; Listerine (R)), and water (negative control).The mouth rinse periods were separated by 3-month washout periods. At days o (baseline) and 17 (end) of each mouth rinse period, gingival crevicular fluid (GCF) was collected at different tooth sites and analyzed with ELISA technique for IL-1 alpha, IL-1 beta and IL-1ra levels. No significant correlations between clinical parameters (OHI and GI) and cytokine concentrations were observed, regardless of mouth rinse regimen.The generalized linear models revealed that none of the mouth rinses had a statistically significant impact on IL-1 concentrations in GCF. Large inter-individual variations were observed for the levels of IL-1 alpha, IL-1 beta and IL-1ra. Also the changes in concentrations between day o and day17 for the mouthrinses showed large intra-individual variations. It can be concluded that neither the alcohol-free chlorhexidine nor the mouth rinse containing essential oils reduced the levels of IL-1 alpha, IL-1 beta and IL-1ra in GCF.

Protein and bacteria binding to exposed root surfaces and the adjacent enamel surfaces in vivo
- 2015
-
In: Swedish Dental Journal. - 0347-9994. ; 39:1, s. 11-22
-
Journal article (peer-reviewed)abstract
- Exposure of root surfaces due to inflammatory tissue breakdown is a clinical characteristic of periodontitis. The gingival margin may further recede during treatment. Pellicles and early dental plaque on enamel surfaces of periodontitis patients have previously been described.The binding properties of exposed root surfaces, which may affect the incorporation of proteins from especially the GCF into the enamel pellicle and thereby early dental plaque formation are largely unknown.The aim of this study was to examine if exposed root surfaces could affect pellicle and initial dental plaque formation on the enamel surface by the analysis of proteins and early adhering bacteria binding to the exposed root surfaces and to the adjacent, gingival enamel surface. Supragingival pellicle and plaque samples were taken from exposed root surfaces and the adjacent enamel surfaces in eleven surgically treated periodontitis patients. For comparison, samples were taken from enamel surfaces of teeth not in need of treatment. Additionally, subgingival bacterial samples were taken. Pellicle proteins were analysed by SDS-PAGE, immunoblotting and image analysis, and bacterial samples by culturing. Significantly more plasma proteins and bacteria were found on the exposed root surfaces than on the enamel.The depth of the gingival recessions was negatively correlated to the amount of plasma proteins in the enamel pellicle./Artv'nomyces spp.were most frequently found on the exposed root surfaces.The total viable counts and streptococci (%TVC) were positively correlated between subgingival samples and samples from the root surface and enamel of surgically treated teeth. A positive correlation was also found for the findings of Gram-negative anaerobes in subgingival samples and samples from the enamel surface. Our findings suggest that an exposed root surface has binding properties different from an enamel surface and could affect early biofilm formation on the adjacent enamel surface.

Journal article (peer-reviewed)abstract
- Turner syndrome (TS) is a genetic disorder of females with a prevalence of 1/2000-3000 live female births. The aim of this study was to compare cephalometric variables from adult women diagnosed with TS to a standardized reference group of 31-year old healthy women, and to evaluate the possible effects of human growth hormone (hGH) therapy in women with TS. Registered TS subjects in the Southeast region of Sweden were invited to take part in the study. Twenty-one women aged 36 +/- 13(18-57) years accepted participation. Lateral radiographs of the head were analyzed using standard cephalometric methods (Hasund analysis) and with the commercially available soft-ware program FACAD. Comparisons were made with roentgen-cephalometric standards from a reference group of nineteen 31-year old Swedish women. Analysis of the cephalometric radiographs from the TS subjects showed a more retrognathic maxilla (SNA 80.3 +/- 5.4) (p=0.0460) and mandible (SNB 77.0 +/- 5.2) (p=0.0014), and a correspondingly backward position of the chin (SN/Pg 78.9 +/- 5.5) (p=0.0046) as compared to the reference values of 31-year old women (SNA 83.2 +/- 3.0, SNB 81.5 +/- 2.3 and SNPg 83.0 +/- 2.3, respectively). In addition there was an increased posterior inclination of the maxilla (SN/NL 8.6 +/- 4.1), as compared to the reference values (SN/NL 5,3 +/- 2.7) (p=0.0048). There were no significant differences regarding sagittal or vertical jaw relations, mandibular inclination or cranial base angle between the TS-group and the 31-year olds with the reference values. No significant difference was seen in jaw relationship, as measured by the ANB value, however the Wits(index) (3.3 +/- 3.5) was higher (p=0.0001) than the reference values (-0.1 +/- 1.8). Subjects with or without previous hGH administration did not show any significant differences in cephalometric values. In conclusion, women with TS had a significantly more retrognathic maxilla (SNA) and mandible (SNB) and a correspondingly significantly posterior position of the chin (SN/Pg), a significantly increased posterior inclination of the maxilla (SN/NL) and a significantly increased Witsindex as compared to the reference group of 31-year old women. No craniofacial variables differed significantly between previously hGH-treated and not hGH-treated women with TS.

Oral condition and background factors in Somali immigrant children newly arrived in Sweden
- 2016
-
In: Swedish Dental Journal. - : Sveriges tandläkarförbund. - 0347-9994. ; 40:2, s. 153-164
-
Journal article (peer-reviewed)abstract
- The aim of the present study was to obtain baseline information about oral health, oral health behaviours and knowledge about prevention of oral diseases in newly arrived Somali children. All 310 Somali children arriving in four municipalities in Kronoberg County, Sweden, during 2013 participated. We collected interview data (background factors related to oral health) and performed a clinical examination (oral hygiene, marginal bone loss, malocclusion, dental caries) within the first two months after arrival. The children were analysed in three age groups: 3-6 years (n=49),7-11 years (n=125), and 12-17 years (n=136). The interview revealed that 78-82% of the children in the three groups had never visited a dental clinic in Somalia.Toothache was reported by 18-28% of the children. In the youngest group, 71% of the parents did not assist with tooth -cleaning and children commonly used a Miswak stick for cleaning. About half the children had poor oral hygiene while 25-33% reported daily intake of sugary snacks. Malocclusion affected 4o% of the 7 -11 -year -olds and 5o% of the 12 -17 -year -olds. Bone loss affected 13% of the 12-17-year-olds.The 3 -6 -year -olds had a high prevalence (37%) of missing primary, lower cuspids.Their mean number of decayed, extracted and filled primary teeth (deft) was 2.3, and 43% were free from caries. In the 7 -11 -year -olds, mean decayed and filled permanent teeth (DFT) was o.8, while in the 12 -17 -year -olds DFT was 2.2 with 4o% caries -free. Comparison with resident children indicates substantially higher caries prevalence among the Somali children. The study has shown that newly arrived Somali children often present with oral diseases and are in urgent need of treatment and have great need for oral health promotion.

Vital root resection with MTA: a pilot study
- 2016
-
In: Swedish Dental Journal. - 0347-9994. ; 40:1, s. 43-51
-
Journal article (peer-reviewed)abstract
- Objectives. To investigate the outcome of vital root resection followed by immediate pulp capping with MTA in furcation involved maxillary molars. Material and methods. This pilot clinical study of 12 months duration was designed to evaluate the outcome of vital root resection in maxillary molars with degree II furcation involvement combined with conservative endodontic treatment by means of pulp capping with mineral trioxide aggregate (MTA). Seven teeth in six adult patients suffering from adult chronic periodontitis were included in this study. Results. At the final 12 month examination interval, one tooth had received root canal therapy subsequent to the 6-month evaluation. The remaining six teeth remained clinically vital for the duration of the study and required no further treatment at 12 months. Conclusion. Results of this study provide limited data that can be used in a further investigation with similar methodology and a sufficient sample size in a randomized clinical trial model.
