This study aimed to assess the prevalence of traumatic injuries of the primary incisors in preschool children from 2 to 5 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined.
A cross-sectional survey
Data were collected through oral examinations and structured interviews, and included socio-economic indicators.
A total of 727 children of both genders were included in the study. 122 of these children were aged 2; 183 aged 3; 178 aged 4 and 186 aged 5.
The prevalence of dental injuries was 8.0% (n = 58). The highest frequency of trauma in the primary teeth was observed at the age of 4. Boys experienced more dental injuries than girls, 12.2% and 4.0%, respectively. The most common crown fracture was in enamel only (57%) followed by crown fracture of enamel and dentin (19%).
The prevalence of dental injuries in Turkish preschool children was very low. The children with incisal overjet greater than 5mm and anterior open bite experienced more dental injuries in primary teeth than their counterparts with normal occlusion. Socio-economic indicators were not statistically significantly associated with the occurrence of traumatic dental injuries.
本研究旨在评估土耳其安纳托利亚东南部2至5岁学龄前儿童乳前牙外伤的患病率。此外，还研究了牙外伤、父母教育水平、家庭收入、覆盖超牙合大小与前牙开牙合之间的关系。
横断面调查
通过口腔检查和结构化访谈收集数据，包括社会经济指标。
共有727名男女儿童纳入本研究。其中122名儿童2岁；183名3岁；178名4岁；186名5岁。
牙外伤患病率为8.0%（n = 58）。乳牙外伤最频发的年龄为4岁。男孩牙外伤发生率高于女孩，分别为12.2%和4.0%。最常见的冠折仅累及釉质（57%），其次是釉质和牙本质冠折（19%）。
土耳其学龄前儿童牙外伤患病率很低。覆盖超牙合大于5mm和前牙开牙合的儿童乳牙外伤发生率高于正常咬合的儿童。社会经济指标与牙外伤的发生无统计学显著关联。
