Trauma dental e o impacto na qualidade de vida de escolares da rede pública em uma cidade no sul do Brasil

Objective To study the impact of dental trauma on the oral health-related quality of life among Brazilian students. Methods A cross-sectional study involving a representative sample of students of the public schools (n = 435) in a city in southern Brazil was carried out. Data on dental trauma were collected through oral examinations using the O’Brien’s criteria (1993) restricted to fractures and avulsions. The Brazilian version of the Oral Impacts on Daily Performances (OIDP) was used in order to collect data on the impact of oral health-related quality of life. Bivariate and multivariate analysis were performed through Poisson log-linear regression with robust estimator with significance levels set at p <0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated. Results The prevalence of dental trauma was 7.2%, and it was associated with the following dimensions: performing daily activities [(PR = 3.52 (95% CI, 1.06-11.75)] (p = 0.040), and speaking [(PR = 3.67 (95% CI, 1.24-10.86)] (p = 0.019) after adjusting for sex, age, dental caries and malocclusion. Conclusion The prevalence of dental trauma found among this population was low, but significantly associated with oral health-related quality of life

Impact of dental caries on quality of life of school children

Objective: To estimate the impact of dental caries on the oral health-related quality of life of school children of public schools of Tubarão, Santa Catarina, Brazil. Material and Methods: A cross-sectional study on a sample of 42310-15 years old students was carried out. The prevalence of dental caries, dental trauma and malocclusion was observed by oral examination based on WHO criteria. The Oral Impact on Daily Performance indicator was used to collect data about the impact on quality of life related to children’s oral health. The Chi-square test was used for bivariate analysis with significance levels set at p<0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated using log-linear Poisson regression with a robust estimator. Results: The prevalence of dental caries was 55.5%. The prevalence of impact on oral health related quality of life was 45.6%. OIDP dimensions significantly associated with dental caries were eating [PR = 1.45 (95%CI 1.06; 2.00)] (p = 0.021), sleeping [(PR = 2.29 (95%CI 1.15; 4.56)] (p = 0.018) and performing daily activities [PR = 2.57 (95%CI 1.06; 6.22)] (p = 0.036) after adjusting for gender, age and presence of dental trauma and malocclusion. Conclusion: Dental caries was found to be significantly associated with oral health-related quality of life of children in activities such as eating, sleeping, and performing daily activities
