BACKGROUND/AIMS: Population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among school children and its association with socioeconomic factors are scarce and offer conflicting results. The aim of this study was to evaluate the impact of TDI on OHRQoL among school children and its association with socioeconomic status.
A cross-sectional study was conducted with 588 12-year-old children enrolled in public and private schools in the urban areas in the city of Diamantina (southeastern Brazil). Clinical examinations were performed for the diagnosis of traumatic dental injury based on Andreasen's classification. The Child Perceptions Questionnaire (CPQ ), which has been validated for the population in Brazil, was employed to evaluate oral health-related quality of life. Socioeconomic status and overjet were also analyzed. Statistical analysis involved the chi-square test and logistic regression.
A total of 29.4% of the students exhibited some type of trauma to at least one tooth. A negative impact on oral health-related quality of life was found in 53.1% of the sample. Traumatic dental injury was associated with a high impact on oral health-related quality of life [OR = 1.61 (95% CI: 1.08-2.39)] and overjet >3 mm [OR = 5.42 (95% CI: 3.66-8.02)]. However, no statistically significant associations were found between TDI and socioeconomic status.
Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health-related quality of life as well as overjet >3 mm.
背景/目的：基于人群的研究调查了创伤性牙损伤（TDI）对学龄儿童口腔健康相关生活质量（OHRQoL）的影响及其与社会经济因素的关联，此类研究较少且结果相互矛盾。本研究的目的是评估TDI对学龄儿童OHRQoL的影响及其与社会经济地位的关联。
对巴西东南部迪亚曼蒂纳市市区公立和私立学校的588名12岁儿童进行了一项横断面研究。根据安德里亚森分类法进行临床检查以诊断创伤性牙损伤。采用已在巴西人群中验证的儿童感知问卷（CPQ）来评估口腔健康相关生活质量。还分析了社会经济地位和覆盖。统计分析包括卡方检验和逻辑回归。
共有29.4%的学生至少有一颗牙齿出现某种类型的创伤。在53.1%的样本中发现对口腔健康相关生活质量有负面影响。创伤性牙损伤与对口腔健康相关生活质量的高影响相关[比值比（OR）=1.61（95%置信区间：1.08 - 2.39）]以及覆盖>3毫米相关[OR = 5.42（95%置信区间：3.66 - 8.02）]。然而，未发现TDI与社会经济地位之间存在统计学上的显著关联。
参与研究的儿童中创伤性牙损伤的患病率较高，且与对口腔健康相关生活质量的高影响以及覆盖>3毫米相关。
