The purpose of the present study was to evaluate the relationship between psychological variables and the clinical diagnosis of temporomandbular disorders (TMD) in 12-year-old adolescents. TMD pain was assessed by RDC/TMD examination (Research Diagnostic Criteria for Temporomandibular Disorders) (Axis I and II). Five-hundred and fifty-eight subjects (330 girls and 228 boys) were examined. Bivariate analyses were performed using the Chi-square test (chi(2)). The logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels. Only 2.19% of the boys and 8.18% of the girls presented one of the Axis I categories. All variables from axis II were related to TMD diagnosis (p < 0.001). Gender was significantly related to TMD diagnosis (p = 0.0028). The risk of TMD incidence for girls was 3.5 times higher than that for boys (Odds Ratio = 3.52, Confidence Interval 1.31-9.43). The individuals who presented the variable 'characteristics of pain intensity' (CPI) higher than 0 had 31 times more risk of TMD incidence (Odds Ratio = 31.361, Confidence interval 6.01-163.5). We concluded that psychological variables and female gender are important risk indicators related to TMD incidence, even in adolescents.

BackgroundOral disorders may negatively affect the quality of life (QoL) of adolescents.To investigate how social vulnerability and oral-health status factors affect QoL in 15–19 years olds who participated in the “SB São Paulo 2015” state survey.MethodsThe relationship of several independent variables, namely Paulista Social Vulnerability Index (PSVI) score, gender, skin color, family income, age, untreated caries, tooth loss [determined by the Decayed, Missing, Filled-Teeth (DMF-T) index], toothache, periodontal condition [determined by the Community Periodontal Index (CPI)], and malocclusion (maxillary overjet, cross bite, or open bite) affect daily life, measured by the Oral Impacts on Daily Performance (OIDP) instrument. Logistic regression analyses were carried out based on a hierarchical model.ResultsThe final sample consisted of 5402 adolescents. The prevalence of at least one negative impact of oral health on QoL was 37.3%. After adjustment, demographic factors that were found to influence this impact significantly (p < 0.01) were female gender [odds ratio (OR) 1.78, 95% confidence interval (CI) = 1.59–2.0], non-white skin color (OR 1.66, 95% CI = 1.47–1.88), and a low family income (OR 1.28, 95% CI = 1.28–1.29). Additionally, oral conditions associated with oral health impact on QoL included the presence of at least one untreated tooth decay lesion (OR 1.42, 95% CI = 1.25–1.61), loss of at least one tooth (OR 1.49; 95% CI = 1.25–1.78), toothache (OR 4.87, 95% CI = 4.25–5.59), bleeding on probing (OR 1.45, 95% CI = 1.25–1.68), and severe maxillary overjet (OR 1.68, 95% CI = 1.15–2.45).ConclusionSocial vulnerability (PSVI score) was not associated with the OIDP score, but oral health conditions and socio-demographic variables, including gender, skin color, and income, were found to affect adolescents’ daily activities. Strategies that consider the perceptions of this segment of the population should be implemented to strengthen their autonomy and totality of care.

The present study investigated the distribution profile of dental caries and its association with areas of social deprivation at the individual and contextual level. The cluster sample consisted of 1,002 12-year-old schoolchildren from Piracicaba, SP, Brazil. The DMFT Index was used for dental caries and the Care Index was used to determine access to dental services. On the individual level, variables were associated with a better oral status. On the contextual level, areas were not associated with oral status. However, maps enabled determining that the central districts have better social and oral conditions than the deprived outlying districts.

Dental caries experience and prevalence in 12-year-old schoolchildren have declined significantly during the last 30 years in Bauru.

Aim To investigate factors that influence the oral health‐related quality of life of older people (65 years and over) in Brazil. Background Population‐based studies should be conducted to support health‐planning interventions. Materials and methods Data from the São Paulo State Survey on Oral Health (SBSP‐2015), which consisted of 5951 individuals, were used. A theoretical‐conceptual model was built based on the impact of family socio‐economic characteristics, individual social‐demographic features and self‐perceived and clinical oral health status on the oral impact on daily performance (OIDP). Multivariate binary logistic regression analysis was conducted at 5% significance level. Statistically significant variables included within the adjusted logistic regression model entered the multiple correspondence analysis (MCA). Results Oral health impact on daily activities was observed in 34.6% of older people. Characteristics significantly related to impact on OIDP score were as follows: family income up to R$ 500 (OR = 2.73), self‐perceived treatment need (OR = 1.33), self‐perceived toothache (OR = 1.52), self‐perception of denture replacement need (OR = 1.27), dissatisfaction (OR = 1.50) or very dissatisfied (OR = 2.57) with own oral health, partial lower denture use (OR = 1.34) and needing partial lower dentures (OR = 1.28). Increased number of people living in the same house (B = 0.05, OR = 1.06), number of bedrooms in the house (B = −0.10, OR = 0.90), age (B = −0.03, OR = 0.97) and number of teeth needing treatment (B = 0.08, OR = 1.08) contributed significantly to OIDP. Conclusion Prevalence of OIDP of older people in the state of São Paulo was related to factors other than their clinical and self‐perceived oral health status.

Resumo Introdução A falta de dentição funcional compromete a qualidade de vida dos indivíduos, podendo refletir nas suas percepções, incluindo a autopercepção da necessidade de tratamento odontológico. No entanto, essa relação ainda não é bem esclarecida na literatura. Objetivo Avaliar se a falta de dentição funcional em adultos está associada à autopercepção da necessidade de tratamento odontológico. Método Foi realizado estudo transversal analítico, no qual foram utilizados dados da Pesquisa Nacional de Saúde Bucal, realizada no ano de 2010. A faixa etária avaliada foi de 35 a 44 anos. Após análise bivariada e múltipla, foi verificada a associação entre a falta de dentição funcional e outras variáveis, como a autopercepção da necessidade de tratamento, as condições sociodemográficas e os desfechos em saúde. Resultados Dos 9.564 adultos, aproximadamente 20% dos indivíduos não possuíam dentição funcional. A falta de dentição funcional foi menor em adultos que perceberam a necessidade de tratamento odontológico (OR:0,55; IC95%:0,39-0,75). O sexo feminino (OR:1,76; IC95%:1,39-2,22), a idade mais avançada (OR:2,53; IC95%:2,01-3,18) e a menor escolaridade (OR:0,82; IC95%:0,79-0,85) estavam associados à falta de dentição funcional. Conclusão A falta de dentição funcional é maior em adultos que não têm autopercepção da necessidade de tratamento odontológico.
