Traumatic dental injury is an injury inflicted on the dentoalveolar system. It has a physical as well as a psychological impact. Despite this concern, epidemiological data regarding its prevalence is insufficient in the literature of Nepal. Hence, this study's objective was to investigate the prevalence of traumatic dental injuries for the patients visiting Universal College of Medical Sciences, Bhairahawa, Nepal, over five years.
A descriptive cross-sectional study was conducted using records from the medical record section for the patients presenting at the dental emergency outpatient department of the Universal College of Medical Sciences, Bhairahawa, Nepal, between April 2014 and April 2019. Ethical approval was taken from the Institutional Review Committee of the Universal College of Medical Sciences. Patient demographic data, type of traumatic dental injuries, and etiologies were evaluated from the record section.
Out of 10,080 patients registered during the study period, 793 patients (7.86%) were due to traumatic dental injury, out of which 628 (79.2%) were male, and 165 (20.8%) were female. The most vulnerable age group was 20-29 years (42.4%). Most frequently, injuries occurred in June (16%). Road traffic accidents (57.8 %) were the most common mode, and complicated crown-root fracture (23.3%) was the most common type of traumatic dental injury.
The frequency of 7.86% of traumatic dental injury indicates that dental traumatology needs special attention for policy planning and professional training.
创伤性牙损伤是对牙牙槽系统造成的损伤。它既有身体上的影响，也有心理上的影响。尽管存在这种担忧，但尼泊尔文献中关于其流行率的流行病学数据仍然不足。因此，本研究的目的是调查在尼泊尔巴伊拉瓦的环球医学院就诊的患者中创伤性牙损伤的流行率，时间跨度为五年。
本研究采用描述性的横断面研究方法，从尼泊尔巴伊拉瓦环球医学院牙科急诊门诊的病历部分获取 2014 年 4 月至 2019 年 4 月期间就诊的患者的记录。本研究已获得环球医学院机构审查委员会的伦理批准。从病历部分评估患者的人口统计学数据、创伤性牙损伤的类型和病因。
在研究期间，有 10080 名患者登记，其中 793 名（7.86%）因创伤性牙损伤就诊，其中 628 名（79.2%）为男性，165 名（20.8%）为女性。最脆弱的年龄组是 20-29 岁（42.4%）。受伤最常发生在 6 月（16%）。道路交通碰撞（57.8%）是最常见的发生模式，复杂冠根折（23.3%）是最常见的创伤性牙损伤类型。
创伤性牙损伤的发生率为 7.86%，这表明需要特别关注牙科外伤学，以制定政策和进行专业培训。
