“…Another home follow up was performed at 12 years, when 339 members of those visited at six years were located. The description of the oral health follow-up methods at six and 12 years is found in a previous publication [14].…”

ObjectiveEstimate the prevalence of dental caries based on clinical examinations and self-reports and compare differences in the prevalence and effect measures between the two methods among 18-year-olds belonging to a 1993 birth cohort in the city of Pelotas, Brazil.MethodData on self-reported caries, socio-demographic aspects and oral health behaviour were collected using a questionnaire administered to adolescents aged 18 years (n = 4041). Clinical caries was evaluated (n = 1014) by a dentist who had undergone training and calibration exercises. Prevalence rates of clinical and self-reported caries, sensitivity, specificity, positive and negative predictive values, absolute and relative bias, and inflation factors were calculated. Prevalence ratios of dental caries were estimated for each risk factor.ResultsThe prevalence of clinical and self-reported caries (DMFT>1) was 66.5% (95%CI: 63.6%–69.3%) and 60.3% (95%CI: 58.8%–61.8%), respectively. Self-reports underestimated the prevalence of dental caries by 9.3% in comparison to clinical evaluations. The analysis of the validity of self-reports regarding the DMFT index indicated high sensitivity (81.8%; 95%CI: 78.7%–84.7%) and specificity (78.1%; 95%CI: 73.3%–82.4%) in relation to the gold standard (clinical evaluation). Both the clinical and self-reported evaluations were associated with gender, schooling and self-rated oral health. Clinical dental caries was associated with visits to the dentist in the previous year. Self-reported dental caries was associated with daily tooth brushing frequency.ConclusionsBased on the present findings, self-reported information on dental caries using the DMFT index requires further studies prior to its use in the analysis of risk factors, but is valid for population-based health surveys with the aim of planning and monitoring oral health actions directed at adolescents.

“…For example, toothbrushing frequency is determined by socioeconomic conditions and may influence dental outcomes such as dental caries and periodontal health. 16,17 Epidemiologically speaking, a mediator is defined as a variable that occurs in a causal pathway from a distal cause to an outcome. It causes variation in the outcome and itself is determined by the original causal variable.…”

“…Regardless of the proposed conceptual framework, there is no dispute that psychosocial factors are mediators of the association between the social conditions (distal determinants) and health (the outcome). For example, toothbrushing frequency is determined by socioeconomic conditions and may influence dental outcomes such as dental caries and periodontal health . Epidemiologically speaking, a mediator is defined as a variable that occurs in a causal pathway from a distal cause to an outcome.…”

ObjectivesTo test whether maternal education has a direct effect on gingival bleeding in adolescents aged 12 and to assess whether oral health behaviours over time mediate that association.MethodsTwo oral health studies nested in the 1993 Pelotas (Brazil) birth cohort study were carried out in participants aged 6 (n = 359) and 12 years (n = 339). The proportion of teeth with bleeding on probing (BOP) and the median number of teeth with gingivitis at age 12 were recorded. Maternal education at birth was the exposure. Toothbrushing frequency and dental visit at ages 6 and 12 years were investigated as mediators of the association between maternal education at birth and gingival bleeding. Time‐varying family income through childhood and adolescence was included as later confounder. Paternal education was taken as baseline confounder. The controlled direct effect (CDE) of maternal education at child's birth on gingival bleeding at age 12 was estimated using marginal structural models (MSM). Additionally, path analysis was employed to estimate standardized direct, indirect and total effects of maternal education at birth on gingival bleeding.ResultsAdjusted analyses using MSM showed that adolescents whose mothers had <8 years of education had 3.82 higher risk of having teeth with gingival bleeding above the median (rate ratio RR 3.82; 95% CI: 1.68‐8.19). Low maternal education doubled the proportion of gingival bleeding at age 12 not mediated by dental visit and toothbrushing frequency (RR 1.99; 95% CI: 1.52‐2.60). Path analysis revealed that maternal education had a direct effect on gingival bleeding independently of the mediators.ConclusionsThe pattern of oral health behaviours does not explain the association between mother's education and adolescent's gingival bleeding. Individual‐based approaches focused on oral health‐related behaviours tend to fail to prevent gingival bleeding.

“…Os questionários aplicados face a face nos estudos de saúde bucal incluíram, no total, cerca de 140 variáveis. Os agravos bucais investigados foram: cárie dentária, problemas oclusais, condições periodontais, uso e necessidade de prótese, qualidade das restaurações em dentes posteriores, traumatismo dentário, fluorose, padrão de emergência dos molares permanentes, lesão em tecidos moles e presença de placa dentária 1,2 . Foram obtidas as aprovações pelo Comitê de Ética em Pesquisa da UFPel e o termo de consentimento dos participantes.…”
