The aim of the study is: (a) investigate the racial inequalities as one specific dimension that affects dental pain in Brazilian adolescents; and (b) investigate the regional variations of dental pain. This cross-sectional study used data from Brazilian National Survey of School Health (PeNSE), carried out with adolescents in 2009, 2012 and 2015. Dental pain was evaluated through the question: "Did you have dental pain in the last six months?". The main exposures were race and Brazilian regions, used to evaluate inequalities related to the outcome. Sex, age, school type and maternal education were used as covariables. The statistical significance of the trends in dental pain was tested using linear regression. The analysis was conducted in Stata 13.0 statistical package using the svy command. The standard prevalence of dental pain was 18.8%, 21.1% and 23.7%, showing an increasing trend over time (p < 0.001). We observed absolute inequalities in dental pain related to race and regions. A higher prevalence was found in non-white girls of public schools and in the Northern Region. The indexes of inequalities increased in the group of black girls, related to an increase of dental pain predominantly in girls whose mothers had lower educational level. It was observed that the prevalence of dental pain in Brazilian adolescents increased over time as well as its inequalities, which remained in marginalized populations and linked to Brazilian regions.
(a) 调查种族不平等这一影响巴西青少年牙痛的特定因素；(b) 调查牙痛的地区差异。本横断面研究使用了巴西全国学校卫生调查（PeNSE）的数据，该调查于 2009 年、2012 年和 2015 年对青少年进行了调查。通过以下问题评估牙痛：“您在过去六个月中有过牙痛吗？”主要暴露因素是种族和巴西地区，用于评估与结果相关的不平等。性别、年龄、学校类型和母亲教育程度被用作协变量。使用线性回归检验了牙痛趋势的统计学意义。使用 Stata 13.0 统计软件包中的 svy 命令进行分析。标准的牙痛患病率为 18.8%、21.1%和 23.7%，呈现出随时间增加的趋势（p<0.001）。我们观察到与种族和地区相关的牙痛存在绝对不平等。公立学校的非白人女孩和北部地区的牙痛患病率较高。在黑人女孩中，与母亲教育水平较低的女孩的牙痛增加相关的不平等指数增加。观察到巴西青少年的牙痛患病率随时间增加，不平等现象依然存在于边缘化人群中，并与巴西地区有关。
