To measure the prevalence of anterior teeth trauma in 9- to 14-year-old schoolchildren and their association with predisposing factors, such as lip competence, molar relationship, overjet, and variables, such as age, gender, and cause of trauma.
Epidemiological cross-sectional study was carried out among 3,012 schoolchildren aged 9 to 14 years in Navi Mumbai (Kharghar-Belapur region). The sample size was derived using the stratified random sampling method; we picked six schools from the region. These schools had 3,000 students in the acceptable age group of the study which constituted our final sample size. All children were examined for traumatic dental injuries, and the children with positive findings were further examined for lip competence, Angle's molar relationship, and overjet. The results were statistically analyzed using cross-tabulation and Chi-square test.
The prevalence of dental injuries was 7.3%, and the ratio of male to female children was found to be 1.6:1. The maximum number of traumatic dental injuries was found with class I molar relationship and overjet less than 3.5 mm in children with competent lips. Maximum number of injuries occurred in the age group of 13-14 years. The most predominant type of injury was the enamel fracture and the most common cause determined was due to fall.
The present study is a collection of data on traumatic injuries to anterior teeth, which is seen very commonly in day-to-day practice. The frequency and cause of traumatic injuries to anterior teeth is important for identification of risk groups, treatment needs, and cost involved in order for establishing effective preventive measures.

测量9至14岁学童上前牙外伤的患病率及其与易患因素的关联，如唇功能、磨牙关系、覆盖，以及年龄、性别和外伤原因等变量。
在新孟买（卡尔哈格-贝拉布尔地区）对3012名9至14岁的学童进行了流行病学横断面研究。样本量采用分层随机抽样方法确定；我们从该地区挑选了六所学校。这些学校有3000名处于研究可接受年龄组的学生，构成了我们的最终样本量。对所有儿童进行牙外伤检查，对检查结果呈阳性的儿童进一步检查唇功能、安氏磨牙关系和覆盖。结果采用交叉表和卡方检验进行统计学分析。
牙外伤患病率为7.3%，男童与女童的比例为1.6:1。在唇功能正常的儿童中，I类磨牙关系且覆盖小于3.5 mm的儿童牙外伤数量最多。受伤最多的年龄组为13至14岁。最主要的损伤类型是釉质骨折，确定的最常见原因是跌倒。
本研究收集了上前牙外伤的数据，这在日常实践中很常见。上前牙外伤的频率和原因对于识别风险群体、治疗需求以及所涉及的成本很重要，以便制定有效的预防措施。
