The aim of this study was to determine the prevalence of traumatic injuries to the anterior teeth and evaluate the role of anatomic risk factors in the occurrence of such injuries in a group with an assumed behavior predisposing them to trauma.
The study population consisted of 370 male enrollees of the National Cadet Corps (NCC) in India. Risk factors such as the socioeconomic status (SES) of parents, lip coverage, incisor overjet, and the cause and nature of trauma to anterior teeth were recorded. The Chi-square test was used for testing the association between these factors. Increasing overjet was further analyzed using chi-square for linear trends. Variables found significant were subjected to logistic regression.
A prevalence of 14.9% of traumatic injuries to anterior teeth was found in the study population with sports activities being the most common cause. Permanent maxillary central incisors were most commonly injured with injuries involving enamel and dentin being the most frequently observed. Increased overjet and inadequate lip coverage were significantly associated with the occurrence of trauma. With an odds ratio of 7.2 inadequate lip coverage was identified, using binary logistic regression, as the single most independent risk factor for the occurrence of traumatic injury to the maxillary anterior teeth.
本研究旨在确定前牙创伤性损伤的患病率,并评估解剖学危险因素在一组具有易发生创伤行为倾向人群中此类损伤发生中的作用。
研究对象为印度国家少年军(NCC)的370名男性入伍者。记录父母的社会经济地位(SES)、唇部覆盖情况、切牙覆盖超 、以及前牙创伤的原因和性质等危险因素。采用卡方检验来检验这些因素之间的关联。使用卡方检验线性趋势对增加的覆盖超 进行进一步分析。对发现有显著意义的变量进行逻辑回归分析。
在研究人群中发现前牙创伤性损伤的患病率为14.9%,体育活动是最常见的原因。上颌恒中切牙最常受伤,釉质和牙本质损伤最为常见。覆盖超 增加和唇部覆盖不足与创伤的发生显著相关。通过二元逻辑回归分析,唇部覆盖不足的优势比为7.2,被确定为上颌前牙创伤性损伤发生的最主要独立危险因素。
