Aim: The aim of the study was to evaluate the prevalence of dental pain in preschool children and its association with socioeconomic, demographic, clinical, and behavior variables. Subjects and Methods: The study was nested in a population-based birth cohort from Pelotas, Brazil, started in 2004. A sample of 1,129 children aged 5 years was dentally examined, and their mothers were interviewed. Exploratory variables included demographics, socioeconomic status, mothers’ oral health status and associated behaviors, and caries in primary teeth. Data were analyzed using multivariable Poisson regression. Results: The prevalence of dental pain was 16.5% (95% CI: 14.4–18.8). Multivariate analysis showed that dark-skinned children (prevalence ratio, PR = 1.6, 95% CI: 1.1–2.4) from low socioeconomic level (PR 1.9, 1.2–3.0) whose mothers had less than 4 years of education (PR 1.9, 1.0–3.6), from mothers with less than 10 teeth in at least one arch (PR 1.7, 1.2–2.5) and less than 10 in two arches (PR 1.6, 1.0–2.6), and those with high caries prevalence at the age of 5 years (PR 4.8, 3.3–7.1) were more likely to experience dental pain. Conclusions: Unrestored caries is the main factor associated with dental pain in childhood. Socioeconomic aspects and family context in which dental pain occurs should also be taken into account when dental pain preventive measures are implemented.

The perception of dental aesthetic appearance may affect social interaction and psychological status, influencing dental needs and the search for treatments. Aim: To investigate the satisfaction with dental appearance and influencing factors among adolescents. Methods: The study was carried out among adolescents aged 14 to 19 years attending a private high school in Brazil. Data on demographic information, the perception of dental appearance, previous aesthetic treatments and wish to perform dental treatments were collected in the school. Data were analyzed using Pearson’s chi-square test or Linear Trend. Multivariate analysis was performed using the Poisson regression. Results: A total of 531 adolescents (Response rate = 98.3%) answered the questionnaire. The prevalence of dissatisfaction with dental appearance was 17.4%. Almost 65% had history of previous orthodontic treatment and 16% performed dental bleaching. Approximately 45% of children wished to undergo orthodontics and 54.8% to bleach their teeth. Dissatisfaction with dental appearance was associated with individuals unsatisfied with dental color (95% IC[1.73;4.32]), those perceiving poor dental alignment (PR3.16 95% IC[2.11;4.72]) and those wishing orthodontic treatment (PR2.9; 95% IC[1.79; 4.70]). Conclusions: The prevalence of dissatisfaction was considerable and was associated with aesthetic concerns such as tooth color, dental alignment and with the wish for orthodontics. In this young population, a large part of adolescents had already performed orthodontic and bleaching treatments and wished to perform those treatments again. Satisfaction with dental appearance could affect the adolescents’ behavior regarding search for dental treatment, thus causing possible overtreatment.

The photographic assessment method of dental trauma was valid and reliable as compared to the oral clinical examination.
