Tooth loss in a young population from south Brazil, Spring. J Public Health Dent. 66:110-5., Number 2
AbstractOBJECTIVES: To assess the prevalence, extent, and risk indicators of tooth loss in a representative young urban population from south Brazil. METHODS: A representative sample was drawn using a multi-stage probability cluster sampling strategy, and consisted of 612 subjects 14-29 years of age in the metropolitan area of Porto Alegre, Brazil. A clinical examination was carried out by 4 calibrated examiners in a mobile examination center. RESULTS: The prevalence of tooth loss was 44.8%, 26%, and 60%, and the mean tooth loss was 1.4, 0.6, and 2.4 teeth in the age groups 14-29, 14-19 and 25-29 years, respectively. First molars were the most frequently missing teeth, and the mandibular incisors and canines were the least missing teeth. Tooth loss increased sharply with age, and was similar in males and females. Having > or =4 missing teeth was significantly associated with low socioeconomic status and heavy smoking, and was significantly more likely in persons who had > or =2 teeth with caries/fillings and/or > or =5 mm attachment loss. CONCLUSION: Tooth loss is a dental health concern in this young Brazilian population. Community-based oral diseases prevention programs targeting groups having these risk factors should be implemented to reduce tooth loss.

Association between psychosocial factors and periodontitis: a case-control study, Feb. J Clin Periodontol. 33:109-14., Number 2
AbstractOBJECTIVE: This case-control study investigated the association between life events, anxiety, and depression with periodontitis. METHODOLOGY: The study counted with 165 individuals, both sexes, 35-60 years of age. Case group included 96 individuals suffering from periodontal disease; and in control group 69 subjects with no history of periodontitis. Clinical examinations were performed by a single examiner. Psychological assessment included four inventories: Life Events Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory and Beck Depression Inventory. Bivariate and multivariate logistic regression analyses were performed to compare cases and controls. RESULTS: Mean probing depth and clinical attachment level were 3.44+/-0.80 and 4.01+/-1.61 in the case group and 1.96+/-0.19 and 0.95+/-0.50 in the control group, respectively (p<0.05). Positive association of periodontitis with age (odds ratio (OR)=1.15 95% confidence interval (CI): 1.06-1.24), male gender (OR=2.71, CI: 1.13-6.49), smoking (OR=6.05, CI: 1.67-21.94) and educational level (OR=6.49, CI: 1.14-36.95) was confirmed. Bivariate analysis did not demonstrate significant mean differences in life events, anxiety symptoms, trait or state of anxiety, or depression symptoms between cases and controls. Multivariate logistic regression, controlling for confounding factors, demonstrated no significant association between psychosocial factors and periodontal disease. CONCLUSIONS: Within the limits of this study it is possible to conclude that there was no significant association between periodontitis and the psychosocial factors analysed.
