Abstract

Purpose: To describe the prevalence and the variables associated with TDIs in schoolchildren aged 8 to 14 years in Estância Velha city in southern Brazil, placing emphasis on molar incisor hypomineralization.

Methods: Students enrolled in public schools of a medium-sized city in the southern Brazil were selected using cluster random sampling. Clinical examinations assessed molar incisor hypomineralization-MIH (European Academy of Pediatric Dentistry criteria), dental caries (DMFT index), and TDIs (O'Brien's criteria). Socioeconomic and demographic variables were assessed using a standardized questionnaire. Prevalence ratios were estimated using Poisson regression (p < 0.05).

Results: 513 students (54.8% female), with a mean age of 11.6 (± 1.9) years, participated in the study. The prevalence of TDIs was 11.3%, with enamel fracture representing 90.4%. The high prevalence of traumatic dental injuries was associated with MIH (PR: 2.22 CI: 1.27; 3.87; p < 0.01) and overjet > 3 mm (PR: 2.03 CI 1.19; 3.45; p < 0.01).

Conclusion: The sample of schoolchildren from southern Brazil had a low prevalence of traumatic dental injuries. Molar incisor hypomineralization and increased overjet were associated with the higher prevalence of traumatic dental injuries.

牙齿外伤与臼齿门牙矿化不足：一项针对巴西南部学龄儿童的横断面研究。

目的：描述巴西南部Estância Velha市8至14岁学龄儿童TDI的患病率和相关变量，重点关注磨牙门齿矿化不足的情况：方法：采用集群随机抽样的方法选取了巴西南部一个中等城市公立学校的在校学生。临床检查评估了臼齿门牙矿化不足-MIH（欧洲儿童牙科学院标准）、龋齿（DMFT指数）和TDIs（奥布莱恩标准）。社会经济和人口统计学变量采用标准化问卷进行评估。采用泊松回归法估算患病率比值（P 结果：513 名学生（54.8% 为女性）中有 1.5%患有龋齿：共有 513 名学生（54.8% 为女生）参加了研究，平均年龄为 11.6 (± 1.9)岁。牙外伤发生率为 11.3%，其中釉质断裂占 90.4%。牙齿外伤的高发率与心肌缺血有关（PR：2.22 CI：1.27；3.87；P 3 mm）（PR：2.03 CI：1.19；3.45；P 结论：来自巴西南部的学龄儿童样本的牙齿外伤发生率较低。臼齿切牙矿化不足和过咬合增加与牙齿外伤发生率较高有关。

期刊介绍： The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
