dental trauma is an irreversible pathology that after occurrence is characterized by life-long debilitating effects. The objectives of this study were to measure the prevalence of anterior teeth fracture and their association with predisposing factors such as lip coverage, molar relationship, overjet, and variables such as age, sex, cause, and place of trauma.
an epidemiological cross-sectional study was carried out among 3708 school children aged 8-13 years in the Vadodara city. All children completed a questionnaire related to history of trauma to their anterior teeth after which they were examined for lip competence, Angle's molar relationship amount of overjet and nature of trauma sustained. The results were statistically analyzed using the prevalence test, Chi-square test, and Mantel-Haenszel Common Odds Ratio.
the prevalence of traumatic injuries was 8.79% and the ratio of boys: girl's was 1.28:1. Inadequate lip coverage group sustained about five times more injuries than the adequate lip coverage group (P = 0.000, OR= 5.407). The maximum traumatic injuries were seen in children having Angle Class II Div 1 molar relationship and/or overjet greater than 5.5 mm and was statistically significant (P<0.05). Maximum number of injuries occurred at 9 years of age. The most predominant injuries were enamel fractures, the most common place for occurrence was home and fall against object, the most frequent cause.
the prevalence of dental injuries in the Vadodara city is high and it has a great potential to be considered as an emerging public health problem.
牙外伤是一种不可逆的病理状况，发生后会产生终身的致残影响。本研究的目的是测量前牙骨折的患病率及其与诸如唇覆盖、磨牙关系、覆盖度等诱发因素，以及年龄、性别、病因和外伤发生地点等变量之间的关联。
在瓦多达拉市对3708名8至13岁的学童进行了一项流行病学横断面研究。所有儿童都填写了一份与前牙外伤史相关的问卷，之后对他们进行唇功能、安氏磨牙关系、覆盖度以及所遭受外伤性质的检查。使用患病率检验、卡方检验和曼特尔-亨泽尔共同比值比进行统计学分析。
外伤发生率为8.79%，男孩与女孩的比例为1.28:1。唇覆盖不足组的受伤次数约为唇覆盖充足组的五倍（P = 0.000，OR = 5.407）。在安氏II类1分类磨牙关系和/或覆盖度大于5.5毫米的儿童中，外伤发生率最高，且具有统计学意义（P<0.05）。受伤次数最多发生在9岁。最主要的损伤是釉质骨折，最常见的发生地点是家中，最常见的原因是摔倒撞到物体。
瓦多达拉市牙外伤的患病率较高，极有可能被视为一个新出现的公共卫生问题。
