RESUMO
PURPOSE: To evaluate the effect of individual and contextual socioeconomic inequalities in the occurrence of untreated dental caries during the transition from childhood to adolescence. METHODS: This 10-year prospective cohort study followed up an initial sample of 639 1-5 years old schoolchildren from southern Brazil. After 7 and 10 years from the baseline (T1), two other reassessments were conducted (T2 and T3), respectively. Untreated dental caries was measured through the International Caries Detection and Assessment System (ICDAS- scores 3, 5 and 6) at T1 and T3. Socioeconomic status (SES) at the contextual and individual level was assessed at T1. At T2, socioeconomic, behavioural and psychosocial characteristics were evaluated as possible pathways of explanation. Structural equation modelling was used to estimate the direct and indirect effects among the variables over 10 years. RESULTS: A total of 429 adolescents were reevaluated at 10-year follow-up (cohort retention rate of 67.1%). About 30.6% presented untreated dental caries at T3. Low individual SES at T1 directly impacted a higher occurrence of dental caries at T3. Non-white skin colour at T1 also indirectly impacted a higher occurrence of dental caries at T3 through low individual SES at T1 and lower household income at T2. Contextual SES did not predict, directly or indirectly, dental caries at T3. CONCLUSION: There is strong evidence that socioeconomic inequalities at the individual level play an important role on the occurrence of dental caries from childhood to adolescence. On the other hand, there was no evidence that contextual SES influences the occurrence of dental caries over time.

OBJECTIVE: To investigate the association between insulin resistance markers and periodontitis in adolescents, analyzing confounder variables and the adiposity as a mediator. METHODS: This is population-based study is representative of adolescents aged 17-18 years from public schools in São Luís, Brazil (n = 405). Insulin resistance was assessed using the Model of Assessment of the Homeostasis of the Insulin Resistance Index (HOMA-IR) and its percussor triglycerides/HDL-cholesterol ratio (TG/HDL-c). The outcome was Initial Periodontitis, a latent variable estimated by the common variance shared among bleeding on probing, probing depth ≥ 4 mm, and clinical attachment loss ≥ 4 mm. The association between insulin resistance and Initial Periodontitis was modeled via pathways triggered by socioeconomic status, smoking, alcohol, and Adiposity, using structural equation modeling. RESULTS: Higher TG/HDL-c was directly associated with higher Initial Periodontitis (standardized coefficient [SC] = 0.130, p < 0.001). HOMA-IR was not associated with periodontal outcome (SC = 0.023, p = 0.075), but it was with Adiposity (SC = 0.495, p < 0.001). Higher TG/HDL-c was associated with Adiposity (SC = 0.202, p < 0.001). CONCLUSION: The insulin resistance markers were associated with early signs of periodontal breakdown among adolescents, suggesting a possible relationship between diabetes and periodontitis commences early in life.

OBJECTIVES: Analyze the association between higher added sugar exposure and periodontal disease in adolescents (18-19 years old). MATERIALS AND METHODS: This was a cross-sectional study nested to RPS Cohorts Consortium, São Luís, Brazil (n = 2515). The exposure was percentage of daily calories from added sugar (≥ 10%), estimated from a quantitative food frequency. The outcome was periodontal disease estimated by the number of teeth affected by bleeding on probing, periodontal probing depth ≥ 4 mm, and clinical attachment level ≥ 4 mm at the same site. A theoretical model was depicted in a directed acyclic graph to identify the minimal sufficient adjustment set: household income, adolescent's educational level, sex, alcohol use, and smoking. Periodontal disease was categorized into < 2 teeth affected, 2 to 3 teeth affected, and ≥ 4 teeth affected to estimate prevalence ratios (PR) by multinomial logistic regression. To test for consistency, means ratio (MR) were estimated using zero-inflated Poisson. RESULTS: High sugar intake was associated with ≥ 4 teeth affected by periodontal disease (PR = 1.42; 95% confidence interval (CI) = 1.03-1.94; p = 0.030); consistency Poisson analysis reinforced these results (MR = 1.15; 95% CI = 1.03-1.29; p = 0.011). CONCLUSION: High level of added sugar intake was associated with greater extent of periodontal disease in adolescents. CLINICAL RELEVANCE: High sugar intake was associated with periodontal disease in adolescents, supporting the integrated hypothesis of dental caries and periodontal disease and giving impetus to future clinical investigation on the effect of restriction of added sugar consumption in periodontal parameters, which potentially may change traditional treatment protocols of periodontal disease.

OBJECTIVES: To explore the sociocultural context in which patients and dentists in urban and rural communities in Southern Brazil interpret dental problems. METHOD: Beliefs and experiences related to dental problems were explored in eight focus groups involving a total of 41 older patients, and in direct interviews with two dentists and two dental assistants. The interactions were audio recorded and transcribed for thematic analysis. RESULTS: The beliefs and experiences of the participants focused on four main themes: cultural beliefs; dental services; decisions to extract teeth; and expectations for change. A culture of pre-nuptial tooth loss and complete dentures was considered beneficial to young women. Although dental services at the time were scarce in the region, demands for relief of pain were extensive despite the fear and anxiety of the participants. Extraction of teeth and fabrication of complete dentures were the usual dental treatments available, although some participants felt that dentists withheld other treatment options. Participants were hopeful that dental services would improve for their children. CONCLUSIONS: Patients and dental professionals in urban and rural communities of Southern Brazil managed dental problems within a culture of limited access and availability of services that favoured dental extractions and complete dentures.

Extensive tooth loss and edentulism can have a negative impact on the general health and quality of life of older adults. The extent to which psychological and social factors affect an individual's decision to undergo tooth extraction and mouth clearance (extraction of all teeth), and the theoretical relationships between social structure, social life and oral health can be unraveled through qualitative research. This study aimed to explore the social and psychological factors involved in tooth extraction and mouth clearance within a historical perspective among rural Southern Brazilian older adults. It is based on qualitative data gathered via a series of eight focus groups among 41 older adults. Underlying the focus group discussions of different levels of health risks and resources for prevention of disease was the concept of vulnerability. Participants' responses illustrated that tooth loss and mouth clearance were related to a lack of public dental health policies and programs, were influenced by social norms (including values pertaining to gender), and were associated with a low level of oral health knowledge. The social and program-dependent contexts of vulnerability were shown to have played a major role in the development of norms and values towards tooth extraction and mouth clearance. Vulnerability must be reduced in order to prevent disease particularly among rural populations. The influence of fatalistic beliefs about the inevitable loss of teeth with age may negatively influence the acceptance of dental treatment and predilection for oral health self-care.
