Dental trauma has become an important attribute of dental public health. The primary requisite before actively dealing with such problems is to describe the extent, distribution, and associated variables with the specific condition.
The aim of the present study was to assess the prevalence and distribution of traumatic dental injuries (TDI) to anterior teeth among 3 to 13 years old Chidambaram school children.
A cross-sectional study was conducted. Data was collected through a survey form and clinical examination.
A total of 3200 school children in the age group of 3-13 years were selected from 10 schools of Chidambaram, Tamilnadu. Information concerning sex, age, cause of trauma, number of injured teeth, type of the teeth, lip competence, terminal plane relationship and the molar relationship were recorded.
The statistical software EPIINFO (Version 6.0) was used for statistical analysis. In the present study, P≤0.05 was considered as the level of significance.
The trauma prevalence in the present study was 10.13%. Children with class I type 2 and mesial step molar relationship exhibited more number of dental injuries. Enamel fracture was the most common injury recorded. Only 3.37% of the children had undergone treatment.
The high level of dental trauma and low percentage of children with trauma seeking treatment stresses the need for increased awareness in Chidambaram population.
牙外伤已成为口腔公共卫生的一个重要特征。在积极应对此类问题之前，首要条件是描述特定情况的范围、分布及相关变量。
本研究的目的是评估奇丹巴拉姆3至13岁学童上前牙外伤（TDI）的患病率和分布情况。
进行了一项横断面研究。通过调查问卷和临床检查收集数据。
从泰米尔纳德邦奇丹巴拉姆的10所学校中选取了3200名3至13岁的学童。记录了有关性别、年龄、外伤原因、受伤牙齿数量、牙齿类型、唇部功能、终末平面关系和磨牙关系的信息。
使用统计软件EPIINFO（版本6.0）进行统计分析。在本研究中，P≤0.05被视为显著性水平。
本研究中的外伤患病率为10.13%。I类2型和近中阶梯磨牙关系的儿童牙齿受伤数量更多。釉质骨折是记录到的最常见损伤。只有3.37%的儿童接受过治疗。
牙外伤发生率高以及寻求治疗的外伤儿童比例低，这凸显了提高奇丹巴拉姆人群意识的必要性。
