BACKGROUND/PURPOSE: Dental injuries in children have functional, esthetic, and psychological effects, with consequences for the child, parent, and dentist. This study assessed the pattern of traumatic dental injuries and their relationship with predisposing factors among 12- and 15-year-old school children in Kanpur, India.
A cross-sectional study was conducted on 1100 boys and girls aged 12 or 15 years. Anterior permanent teeth were examined based on the modified Ellis classification. Type of damage, size of incisal overjet, and adequacy of lip coverage were also recorded. Chi-square tests and multiple regression analysis were used for statistical analysis.
The prevalence of traumatic dental injuries to anterior teeth was 10.9%. Age and gender distribution indicated that most injuries occurred in 15-year-old age group (11.3%) and among boys (11.5%). The gender-related difference was statistically significant (p < 0.024). Maxillary central incisors (83.7%) were frequently involved. The predominant injury type was enamel fracture (68.3%) mainly due to falls (52.5%). Increased overjet, inadequate lip coverage, type of school, and gender were significant contributing factors for traumatic dental injuries.
Study reveals the frequency and cause of traumatic injuries to anterior teeth, which assists in identifying risk groups and treatment needs in order to establish effective preventive strategies.
背景/目的：儿童牙齿损伤会对其功能、美观及心理产生影响，给儿童、家长和牙医都带来后果。本研究评估了印度坎普尔12岁和15岁学童的创伤性牙齿损伤模式及其与诱发因素的关系。
对1100名12岁或15岁的男孩和女孩进行了一项横断面研究。根据改良的埃利斯分类法检查恒牙前牙。还记录了损伤类型、切牙覆盖超突大小和唇部覆盖情况。采用卡方检验和多元回归分析进行统计分析。
前牙创伤性牙齿损伤的患病率为10.9%。年龄和性别分布表明，大多数损伤发生在15岁年龄组（11.3%）和男孩中（11.5%）。性别差异具有统计学意义（p<0.024）。上颌中切牙（83.7%）最常受累。主要损伤类型是牙釉质骨折（68.3%），主要原因是跌倒（52.5%）。覆盖超突增加、唇部覆盖不足、学校类型和性别是创伤性牙齿损伤的重要促成因素。
研究揭示了前牙创伤性损伤的频率和原因，有助于识别风险群体和治疗需求，从而制定有效的预防策略。
