  • A 24-year follow-up of root filled teeth and periapical health amongst middle aged and elderly women in Göteborg, Sweden.
  • 2005
  • Ingår i: International endodontic journal. - : Wiley. - 0143-2885 .- 1365-2591. ; 38:4, s. 246-54

    • AIM: To describe the endodontic status amongst middle-aged and elderly women longitudinally and cross-sectionally over 24 years. METHODOLOGY: A random sample of 1462 women 38, 46, 50, 54 and 60 years old, living in Göteborg, Sweden, were sampled in 1968 for medical and dental examinations with a participation rate of 90.1%. The same women were re-examined in 1980 and 1992 together with new 38- and 50-year-old women. The dental examination consisted of questionnaires, clinical and panoramic radiological survey (OPG). The number of teeth, number of root filled teeth (RF) and number of teeth with periapical radiolucencies (PA) were registered. The RF and PA ratios were calculated. Cross-sectional data were analysed by means of anova and longitudinal data by a general linear model for repeated measures. Sample prevalences were compared and statistical inferences were made with the chi-squared test. In all analysis, the confidence interval (CI) regarded mean difference between groups (95% CI). RESULTS: The RF and PA ratio decreased over time as well as the frequency of edentulous subjects. Cross-sectional analysis revealed a minor increase in frequency of RF and PA and loss of teeth with age. Longitudinally, loss of teeth was evident in all cohorts. In addition, there was a trend of lower number of teeth with PA, and the RF ratio increased with age. CONCLUSIONS: The prevalence of periapical disease did not increase with age, probably as a result of root canal treatment and extractions. Data showed that the prevalence of RF teeth and teeth with PA decreased for comparable age cohorts during the 24-year follow-up.

  • Endodontic variables and coronary heart disease.
  • 2003
  • Ingår i: Acta odontologica Scandinavica. - : Taylor & Francis. - 0001-6357 .- 1502-3850. ; 61:5, s. 257-62

    • This cross-sectional study was designed to explore a possible association between endodontic disease variables and coronary heart disease (CHD). Dental infections are hypothesized to be linked to atherosclerosis and could be a cause of vascular changes crucial for the development of CHD. Most studies have focused on periodontal disease. To our knowledge, no one has specifically studied endodontic variables as risk factors for the development of CHD. In 1992-93, a representative sample (n = 1056) of women in Göteborg, Sweden, aged between 38 and 84 years, took part in a combined dental and medical survey. The dependent variable was CHD, i.e. subjects with angina pectoris and/or a history of myocardial infarction (n = 106). The independent variables were number of root-filled teeth (RF), number of teeth with periapical radiolucencies (PA), tooth loss (TL), age, life situation, marital status, smoking, alcohol habits, body mass index, waist-hip ratio, serum cholesterol and triglyceride concentrations, hypertension and diabetes. The multivariate logistic regression analysis did not prove the endodontic variables to be predictive of CHD. Only age and tooth loss were significantly associated with CHD, with OR = 1.07 (CI = 1.03-1.12) and OR = 2.70 (CI = 1.49-4.87), respectively. The bivariate logistic regression analysis showed a positive significant association between subjects with RF = 2 and CHD, but for PA the bivariate analysis did not support an association with CHD. This cross-sectional study did not reveal a significant association between endodontically treated teeth and CHD nor between teeth with periapical disease and CHD.

  • Pulp exposures in adults--choice of treatment among Swedish dentists.
  • 2013
  • Ingår i: Swedish dental journal. - : Sveriges tandläkarförbund. - 0347-9994. ; 37:3, s. 153-60
  • Tidskriftsartikel (refereegranskat)abstract
    • This study comprises a survey of Swedish dentists'treatment preferences in cases of carious exposure of the dental pulp in adults.The survey was conducted as part of a comprehensive report on methods of diagnosis and treatment in endodontics, published in 2010 by the Swedish Council on Health Technology Assessment. A questionnaire was mailed to a random subsample of 2012 dental offices where one dentist at each office was requested to answer all questions. Each questionnaire contained one of three sets of questions about endodontic practice routines.Thus around one-third of the subsample received case-specific questions about treating carious exposure. Only general practitioners aged below 70 years were included.The final study sample comprised 412 participants.The dentists were presented with two case scenarios. In Case 1 a 22-year old patient had a deep carious lesion in tooth 36 and in Case 2 a 50-year old patient had a deep carious lesion in tooth 14.The participants were asked to nominate their treatment of choice: pulp capping, partial pulpotomy or pulpectomy. For Case 1, 17 per cent of the respondents selected pulpectomy; the corresponding rate for Case 2 was 47 per cent. Female gender and age group 25-49 years were predictive of selection of less invasive treatment options. However, according to recent guidelines (2011) from the National Board of Health and Wellfare, Swedish dentists are recommended to elect pulpectomy prior to pulp capping/partial pulpotomy when confronted with a tooth having a cariously exposed pulp in adults.

  • Socio-economic risk indicators for apical periodontitis.
  • 2006
  • Ingår i: Acta odontologica Scandinavica. - : Informa UK Limited. - 0001-6357 .- 1502-3850. ; 64:2, s. 123-8
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The aim of this study was to reveal possible socio-economic risk indicators for apical periodontitis. MATERIAL AND METHODS: In 1992-93 a representative sample of women in Göteborg, Sweden, aged 38-84 years, participated in a medical and dental survey (n=981) which included dental and medical examinations and dental radiographic examination (OP). The dependent variable was apical periodontitis (AP=0, AP>0). The independent variables were age, number of teeth, number of restored teeth, number of root-filled teeth, number of teeth with carious lesions, satisfactory masticatory function, and dental esthetics as crude measures of self-reported dental health, dental anxiety, time elapsed since last visit to a dental office, regular dental visiting habits, smoking, alcohol habits, and marital status. A subjective evaluation of economy, health and life situation (acceptable or poor) was accounted for as socio-economic variables. The oldest age group, women born 1908, and edentulous individuals were omitted, leaving 844 subjects for analysis. Statistical analysis included multivariate logistic regression, chi-squared test, and independent t-test for comparison of group characteristics (AP=0 vs AP>0). RESULTS: For socio-economic variables there was a significant association between acceptable health and apical periodontitis (OR=1.72 (CI=1.09-2.70)). For oral-related variables, root-filled teeth (OR=1.17 (CI=1.10-1.23)) and teeth with carious lesions (OR=1.48 (CI=1.19-1.85)) were predictive of apical periodontitis. CONCLUSIONS: In the present study, socio-economic variables and dental visiting habits did not appear to have obvious implications for periapical health, whereas root-filled teeth and carious lesions were associated with apical periodontitis.

  • Technical quality of root fillings and periapical status in root filled teeth in Jönköping, Sweden.
  • 2008
  • Ingår i: International endodontic journal. - : Wiley. - 1365-2591 .- 0143-2885. ; 41:11, s. 958-68
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To study changes in technical quality of root fillings and periapical status in root filled teeth in random samples of 20 to 70 year-olds between 1973 and 2003. METHODOLOGY: Data from dentate subjects aged 20-70 years from examinations conducted in 1973 (n = 498), 1983 (n = 530), 1993 (n = 547) and 2003 (n = 491) were used for the analysis. Length of root fillings were measured on radiographs to the nearest 0.1 mm. Adequate seal was defined as a root filling without lateral and/or apical voids. Periapical status was assessed according to the periapical index. All observations were made by one calibrated observer registered from full mouth radiographic examinations. Teeth with root fillings ending within the canal without lateral or apical voids were considered adequate. The association between root filling quality and periapical status was analysed by means of the Chi-squared test and a multilevel logistic regression analysis. RESULTS: Adequately root filled teeth had a significantly lower frequency of apical periodontitis than inadequately root filled teeth (11.8% vs. 22.8%). The frequency of technically adequate root fillings increased statistically significant from 1973 (23.7%) to 2003 (36.4%) without a concomitant improvement of the periapical status in root filled teeth over time (24.5% vs. 24.6%). CONCLUSIONS: This study reports on an improving technical quality of root fillings over time, without a concomitant improvement of the periapical status in root filled teeth. A larger proportion of treated molars over time may be of importance for the result.

    • The radiographic trabecular pattern on dental radiographs may be used to predict fractures. The aim of this study was to analyze longitudinal changes in the mandibles of 145 females between 1980 and 2005.Panoramic radiographs were obtained in 1980 and 2005. On 290 radiographs, regions of interest (ROIs) were selected in the ramus, angle and body. In all ROIs, the orientation was measured in 36 directions with the line frequency deviation method. The effects of ageing were analyzed for the fracture and the non-fracture groups separately.During the follow-up, 61 females suffered fractures of the hip, wrist, spine, leg or arm. The fracture and non-fracture groups displayed dissimilar age changes in each investigated ROI. All significant changes pertained to increasing values of line frequency deviation. With increasing age, the trabecular network in the mandible lost details and the trabeculae became more aligned in their main direction. In the "ramus", the alignment was to the 110-120˚ axis, parallel to the posterior and anterior ramus border. In the "angle", the alignment was to the 135-150˚ axis, parallel to the oblique line, and in the "body" ROI to the 150-175˚ direction, approximately parallel to the occlusal plane and inferior cortex.Most changes were consistent with the notion that the bone aged less severely in the non-fracture group. In the fracture group, the findings indicate that bone loss leads to redistribution of the remaining bone tissue in such a way that the trabeculae are accentuated perpendicular to the principal loading.

  • Predicting fractures using trabecular patterns on panoramic radiographs.

    • 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 26 years 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.

  • Incidence of periapical lesions and clinical symptoms after pulpectomy--a clinical and radiographic evaluation of 1- versus 2-session treatment.
  • 2006
  • Ingår i: Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics. - : Elsevier BV. - 1528-395X .- 1079-2104. ; 101:3, s. 379-88

    • OBJECTIVE: Outcome of pulpectomy in 2 treatment sessions with calcium hydroxide as an intracanal dressing was compared to a procedure comprising instrumentation and root-filling in 1 session. STUDY DESIGN: Subjects with a vital pulp condition (N = 256) were recruited to a randomized clinical trial. Outcome parameters included radiographic signs of apical periodontitis and painful symptoms at clinical follow-ups 1 week and 1-3 years after treatment. RESULTS: Of 244 subjects available for final recall, 17 presented with periapical radiolucency. Lesions were evenly distributed among the 2 treatment groups. Postoperative pain recorded 1 week after permanent filling was significantly associated with overfilling (P = .001), with no difference between treatment groups. There was no association with presence of overfilling and radiographic lesion at end point of recall. CONCLUSIONS: Study confirms that pulpectomy may be carried out at a high rate of success if due attention is given to aseptic operating procedures, proper instrumentation and filling. Under these conditions an interappointment dressing with calcium hydroxide does not seem to influence outcome.

  • Dietary intake and meal patterns among young adults with high caries activity : a cross-sectional study
  • 2022
  • Ingår i: BMC Oral Health. - : BioMed Central. - 1472-6831 .- 1472-6831. ; 22
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundDental caries is a multifactorial disease that is highly dependent on diet, where a lower consumption and intake frequency of sugar would be favorable. The aims were (i) to examine dietary intake and meal patterns, more specifically sugar intake and foods high in sugar, among young adults with high caries activity, and (ii) to investigate the association between dietary and meal patterns consumption, and level of caries activity.MethodsThis study presents baseline data from an ongoing randomized controlled trial. A total of 50 young adults (aged 23.0 ± 3.0 years) with ≥ 2 decayed tooth surfaces were included. Dietary intake was captured with a 59-item food frequency questionnaire (FFQ) and a three-day food diary. Adherence to dietary guidelines was analyzed by comparing the dietary intake to the Nordic Nutritional Recommendations (NNR) 2012 and by using the Healthy Dietary Adherence score (HDAS). Participants were categorized into two groups: (i) the Caries group with 2–4 decayed surfaces, and (ii) the High caries group with ≥ 5 decayed surfaces.ResultsThe High caries group reported a statistically significantly higher snack and total meal intake compared to the Caries group, as well as a sugar intake exceeding the Nordic nutritional recommendations. The majority of the participants reported a high intake frequency (> 2.5/day) of sweet foods and drinks and less than one intake of fruit and vegetables, respectively, per day. Similar results were found when analyzing adherence by using the HDAS, where the lowest adherence according to dietary guidelines was shown for the food groups of sugar, whole meal products, and fruit and vegetables.ConclusionThe results indicated a high intake of sugar and low intake of fruit, vegetables, and fiber in high caries-active individuals.

    • The aim of the present study was to evaluate the effect of a brief version of the behavioral intervention Acceptance and Commitment Therapy (ACT) on reducing gingivitis and plaque levels after 18 weeks.One hundred thirty-five caries-active young adults (18-25 years of age), recruited from two public dental clinics, participated in this parallel group randomized control trial (RCT). Participants in the intervention (n = 67) received two ACT sessions in combination with standard information on oral health, and participants allocated to the control group (n = 68) received standard information only. Gingivitis and plaque levels were recorded at baseline and at the 9- and 18-week follow-ups. The effect of the intervention versus standard information alone was analyzed by intention-to-treat and per protocol, applying the General Linear Model (GLM). Exploratory analyses for the intervention and control groups were conducted to evaluate the effect of gender and smoking habits on the gingivitis and plaque outcome. The CONSORT guidelines for RCT were followed.A significant decrease in gingivitis and plaque levels was observed over time, irrespective of treatment allocation. However, the ACT intervention was not significantly more effective at reducing gingivitis and plaque scores than standard information alone, even though the intervention participants had maintained their improvement to a greater extent. The exploratory analysis revealed that females improved their gingivitis and plaque levels significantly more than the males in the intervention group (p = 0.025 for gingivitis and p = 0.013 for plaque).A brief ACT intervention was not proven to be more effective than standard information alone at improving oral health in a sample of young adults with poor oral health. However, ACT seems to have a positive effect on oral health among females. (TRN ISRCTN15009620).
