This cross-sectional survey was carried out to ascertain the prevalence of fractured incisors in 11-12-year-olds. In addition we explored the relationship with overjet, incompetent lips, incisor inclination and to determine if there was any association with ethnicity and gender. All permanent incisors were examined in 672 children comprising 356 females (53.1%) and 315 males (46.9%). The sample comprised 11-12-year-olds in high schools across Trinidad and Tobago. Statistical analysis was undertaken using Chi-square test, independent t-test, and binary logistic regression. The prevalence of fractured incisors was 18.9%. Boys presented with an increased incidence of fractured incisors than girls. 86.3% of dental trauma was untreated. The average overjet of subjects with fractured incisors was 4.2 mm. 18.62% of subjects with fractured incisors had incompetent lips. The most common malocclusion (18.81%) with fractured incisors was class 2 division 1. The Afro-Trinidadian ethnicity had the highest prevalence of fractured incisors (11.0%) when compared to mixed ethnicities, which was statistically significant. Maxillary central incisors were the most commonly injured teeth. Most patients delayed in seeking dental treatment for fractured incisors in our population. Early orthodontic treatment is recommended to help reduce the risk of dental trauma.
本次横断面调查旨在确定11至12岁儿童中切牙骨折的患病率。此外，我们还探讨了其与覆盖、唇功能不全、切牙倾斜度的关系，并确定其是否与种族和性别有关。对672名儿童的所有恒牙进行了检查，其中包括356名女性（53.1%）和315名男性（46.9%）。样本包括特立尼达和多巴哥各地高中的11至12岁儿童。采用卡方检验、独立t检验和二元逻辑回归进行统计分析。切牙骨折的患病率为18.9%。男孩切牙骨折的发生率高于女孩。86.3%的牙外伤未得到治疗。切牙骨折患者的平均覆盖为4.2毫米。18.62%的切牙骨折患者存在唇功能不全。切牙骨折最常见的错牙合类型（18.81%）为安氏Ⅱ类1分类。与其他混合种族相比，非裔特立尼达种族切牙骨折的患病率最高（11.0%），具有统计学意义。上颌中切牙是最常受伤的牙齿。在我们的研究人群中，大多数患者因切牙骨折而延迟寻求牙科治疗。建议早期进行正畸治疗，以帮助降低牙外伤的风险。
