To assess and compare the prevalence of dental trauma in a population of 9- to 16-year-old children with partially impaired vision and sighted children of Jodhpur city, Rajasthan State in India.
In this cross-sectional study, 121 children with partial impairment of vision were compared with a control group of 356 sighted children for traumatic injuries to the permanent dentition. Children in both the group were aged between 9 and 16 years and residing in a residential school. The survey was carried out using Ellis and Davy's classification of tooth fracture. Data were analyzed using descriptive statistical analysis, and the Chi-square test was used to compare different variables with P < .05.
The overall prevalence rates of traumatic dental injury (TDI) in the visually impaired and sighted groups were 24.79% and 9.39%, respectively (P = .000). Enamel fracture was the most common type of injury, and the maxillary central incisor was most frequently involved in both the groups. Children with overjet >3 mm sustained TDI more frequently in visually impaired children. TDI was higher in children with overjet ≤3 mm in sighted groups (P = .000). In both the groups children with inadequate lip coverage had higher occurrence of TDI (P = .000).
Dental trauma appeared to be more frequent in visually impaired compared to sighted children. The unmet treatment need for children with TDI was very high.
评估和比较印度拉贾斯坦邦焦特布尔市 9 至 16 岁视力部分受损儿童和视力正常儿童的牙齿外伤患病率。
在这项横断面研究中，将 121 名视力部分受损的儿童与对照组 356 名视力正常的儿童进行比较，评估其恒牙外伤情况。两组儿童年龄均在 9 至 16 岁之间，且都居住在寄宿学校。使用 Ellis 和 Davy 的牙齿折断分类法进行调查。使用描述性统计分析进行数据分析，并使用卡方检验比较不同变量，P<.05。
视力受损组和视力正常组的创伤性牙外伤（TDI）总患病率分别为 24.79%和 9.39%（P<.0001）。釉质骨折是最常见的损伤类型，上颌中切牙是两组中最常受累的牙齿。上颌前突>3mm的儿童更易发生 TDI；上颌前突≤3mm的视力正常儿童的 TDI 发生率更高（P<.0001）。两组中唇覆盖不足的儿童 TDI 发生率更高（P<.0001）。
与视力正常的儿童相比，视力受损的儿童的牙齿外伤似乎更为常见。TDI 儿童的未满足治疗需求非常高。
