The present study was conducted to assess the correlation of traumatic dental injuries and overjet among school going girls of age 11 to 17 years in Pune, India.
A cross-sectional survey was carried out with 2045 school girls aged 11 to 17 years, attending public elementary schools in Pune, India. The traumatic dental injuries were assessed according to Ellis and Davey’s criteria. Occlusion was recorded according to Angle´s classification and overjet was measured using a WHO 621 probe. The data obtained was subjected to statistical analysis using Mann-Whitney test.
There was a significant (Z -2.785) association between increase in overjet and occurrence of trauma. Children with increased overjet were 3.09 times more likely to have dental injuries.
It can be concluded from the present study that a significant correlation exists between amount of overjet and prevalence of traumatic injuries among children. The percentage of trauma prevalence increases with the increase of overjet.
Traumatic dental injury is not a result of disease but a consequence of several factors that will accumulate throughout life if not properly treated. One of the most important factors significantly contributing to traumatic dental injuries is the anterior overjet. Hence, correction of increased anterior overjet may help in prevention of traumatic injuries.
本研究旨在评估印度浦那11至17岁在校女生中牙外伤与覆盖的相关性。
对印度浦那公立小学2045名11至17岁的在校女生进行了横断面调查。根据埃利斯和戴维的标准评估牙外伤情况。根据安格尔分类法记录咬合情况，并使用世界卫生组织621型探针测量覆盖。对获得的数据采用曼-惠特尼检验进行统计分析。
覆盖增加与外伤发生之间存在显著关联（Z=-2.785）。覆盖增加的儿童发生牙外伤的可能性是其他儿童的3.09倍。
从本研究可以得出结论，儿童覆盖量与外伤患病率之间存在显著相关性。外伤患病率百分比随覆盖增加而上升。
牙外伤不是疾病的结果，而是多种因素的后果，如果治疗不当，这些因素会在一生中不断累积。导致牙外伤的最重要因素之一是前牙覆盖。因此，纠正增加的前牙覆盖可能有助于预防外伤。
