Abstract
Aim: To assess oral health-related quality of life (OHRQoL) and associated factors among the 12-year-old population of the state of Minas Gerais, Brazil. Methods: Cross-sectional data from the SB-Minas Gerais 2012 study were used. The presence of poor OHRQoL was assessed using the Oral Impact on Daily Performance (OIDP) and its dimensions (physical, psychological and social domains). Independent variables included sociodemographic factors and variables related to the use of dental care and oral health conditions. The association between the outcomes and the independent variables were tested using logistic regression and the results reported as odds ratio with 95% confidence interval. Results: Prevalence of poor OHRQoL was 31.4%; the psychological domain was the most affected (22.6%). Pain and dissatisfaction with oral health were associated with poor OHRQoL on overall OIDP and all its domains. Non-whites had greater poor OHRQoL than whites on overall OIDP and physical domain. Conclusion: Self-perceived oral health and social inequalities were associated with poor OHRQoL.

Summary
Poor oral health-related quality of life (OHRQoL) is reported by one-third of 12-yearolds[1] and two-fifths of the 15–19-year olds in Brazil[2]. The negative impact of oral health on quality of life can be understood as the burden that oral disorders play in daily life, the system of values, and perception of life as a whole within a cultural context and in relation to personal objectives, standards and concerns[6]. These impairments occur hierarchically[7]; speech and chewing functions are the first dimensions to be affected[1,8], are psychological losses, such as restrictions on smiling[9], sleep disorders and anxiety or irritability[1]. Non-whites[2], those in lower levels of income[1] and schooling[2], and people facing barriers to access dental services[1] have been the most affected in their quality of life
