To evaluate the impact of traumatic dental injuries (TDI) on oral health-related quality of life (OHRQoL) among Brazilian adolescents.
A population-based case-control study was carried out, which was nested to a cross-sectional study with a sample of 1215 adolescents aged 11-14 years from Belo Horizonte, Brazil. OHRQoL was measured using the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14 )--Impact Short Form (ISF:16). Two-step cluster analysis was performed to define cases and controls based on CPQ11-14--ISF:16 scores. This method considers the pattern of responses for each item separately and how important each item is to the formation of clusters. The case group included those adolescents who presented higher negative impact on OHRQoL (n=405), while the control group included those with lower negative impact (n=810). Two controls for each case were individually matched from the same school and gender. The main independent variable was TDI, diagnosed by the Andreasen's classification. Untreated dental caries, malocclusion, and age were confounding variables. Conditional logistic regression analysis was performed with the significance level set at 5%.
A multiple conditional logistic regression model demonstrates that adolescents diagnosed with fracture involving dentin and/or pulp had a 2.40-fold greater chance of presenting high negative impact on QHRQoL [95% CI=1.26-4.58; P=0.008] than those without evidence of fractures. Enamel fracture only [P=0.065] and restored fractures [P=0.072] were not statistically associated with OHRQoL.
Adolescents with more severe untreated TDI, such as fractures involving dentin and/or pulp, were more likely to self-report a higher negative impact on their OHRQoL than those without TDI.
评估创伤性牙外伤（TDI）对巴西青少年口腔健康相关生活质量（OHRQoL）的影响。
进行了一项基于人群的病例对照研究，该研究嵌套在巴西贝洛奥里藏特的一项横断面研究中，样本量为 1215 名 11-14 岁的青少年。OHRQoL 使用巴西版儿童感知问卷（CPQ11-14）-影响短表（ISF：16）进行测量。两步聚类分析基于 CPQ11-14-ISF：16 得分对病例和对照进行定义。该方法分别考虑每个项目的反应模式以及每个项目对聚类形成的重要性。病例组包括那些 OHRQoL 受负面影响较大的青少年（n=405），对照组包括那些受负面影响较小的青少年（n=810）。从同一所学校和性别中为每个病例匹配了 2 个对照。主要的独立变量是由 Andreasen 分类法诊断的 TDI。未经治疗的龋齿、错畸形和年龄是混杂变量。使用 5%的显著性水平进行条件逻辑回归分析。
多元条件逻辑回归模型表明，被诊断为牙本质和/或牙髓受累骨折的青少年出现高 OHRQoL 负面影响的可能性是无骨折青少年的 2.40 倍[95%CI=1.26-4.58；P=0.008]。单纯釉质骨折[P=0.065]和修复性骨折[P=0.072]与 OHRQoL 无统计学关联。
与无 TDI 的青少年相比，未治疗的 TDI 更严重的青少年，如牙本质和/或牙髓受累骨折，更有可能自我报告对 OHRQoL 产生更高的负面影响。
