To assess the prevalence of, and correlates of traumatic dental injuries among 12-year-old schoolchildren in Kerala.
A cross-sectional, two-stage cluster sampling technique was used. The sample size included 838 12-year-old school children. Traumatic dental injuries to the anterior teeth were evaluated clinically by one examiner. Teeth examined were maxillary and mandibular incisors and canines. The children answered a structured questionnaire on sociodemographics, subjective oral health assessments and behavioural aspects.
Six per cent of the 12-year-old school children had traumatic dental injuries to the anterior teeth. The right central incisors were most frequently affected. Multiple logistic regression analysis showed that boys (Adjusted Odds Ratio (Adj OR) = 2.2, 95% Confidence Interval (CI) = 1.1-4.1) and children who disagreed that good marks in school were important to them (Adj OR = 2.3, 95% CI = 1.2-4.3) had a higher probability of having traumatized teeth than other children.
The prevalence of traumatized anterior teeth among 12-year-olds in Kerala was low compared with other studies. Being male and negative about future career were associated with a higher probability of having a traumatized tooth.
评估喀拉拉邦 12 岁学童中创伤性牙外伤的发生率及相关因素。
采用横断面、两阶段聚类抽样技术。样本量包括 838 名 12 岁学童。由一名检查者对前牙的创伤性牙外伤进行临床评估。检查的牙齿包括上颌和下颌切牙和尖牙。儿童回答了一份关于社会人口统计学、主观口腔健康评估和行为方面的结构化问卷。
6%的 12 岁学童有前牙创伤性牙外伤。最常受累的是右侧中切牙。多因素逻辑回归分析显示，男孩（调整后的优势比（Adj OR）=2.2，95%置信区间（CI）=1.1-4.1）和认为学校成绩不重要的儿童（Adj OR =2.3，95% CI = 1.2-4.3）比其他儿童更有可能有受伤的牙齿。
与其他研究相比，喀拉拉邦 12 岁儿童前牙创伤的发生率较低。男性和对未来职业的负面看法与牙齿受伤的可能性更高有关。
