BACKGROUND/AIMS: Traumatic dental injuries (TDI) are one of the most commonly encountered dental health complications. In order to standardize the evaluations and compare the findings of TDI, a carefully defined dental trauma index may serve as a good tool for the correct recording of dental trauma. A new dental trauma index, the Modified Eden & Baysal dental trauma index (MEBTI), has been introduced. It is an expanded index to record soft tissue injuries in addition to dental injuries. The aim of this study was to assess the validity and reliability of the MEBDTI.
The archival data of 20 patients with different traumatic injuries were selected. A web-based form including the radiographs and photographs of selected cases was created. Following a training session, 12 dentists with a minimum of 10 years of clinical experience were asked to score the cases using the MEBDTI on an online form. The Kolmogorov-Smirnov test was used to test the normality. The Kruskal-Wallis Test was used for intergroup comparisons. Inter-observer agreement was investigated by reliability analysis. The intraclass correlation coefficient (ICC) was used to evaluate the agreement among observers. The Chi-Square test of independence was used to determine if there is a significant relationship between two nominal variables (p < .05).
The rate of correctly assessing the alveolar bone fracture was 96.9% followed by apex maturity (92.7%), root fracture (85.4%), luxation injury (76.5%), crown fracture (76.2%), and soft tissue injury (50%). Considering all parameters, the soft tissue injuries were statistically different in terms of the answers given by the 12 dentists (p < .05).
The accuracy of the scores of participants was high and in accordance with each other except for the identification of soft tissue injuries. In favor of this novel index, the data on dental trauma cases could be recorded practically and reliably.
背景/目的：创伤性牙损伤（TDI）是最常见的口腔健康并发症之一。为了规范 TDI 的评估并比较 TDI 的结果，精心定义的牙科创伤指数可以作为正确记录牙科创伤的良好工具。一种新的牙科创伤指数，改良 Eden 和 Baysal 牙科创伤指数（MEBTI）已经推出。它是一个扩展的指数，除了记录牙齿损伤外，还记录软组织损伤。本研究旨在评估 MEBDTI 的有效性和可靠性。
选择了 20 名患有不同创伤性损伤的患者的存档数据。创建了一个包含所选病例的 X 光片和照片的基于网络的表格。在培训课程之后，要求 12 名具有至少 10 年临床经验的牙医在在线表格上使用 MEBDTI 对病例进行评分。使用 Kolmogorov-Smirnov 检验来检验正态性。使用 Kruskal-Wallis 检验进行组间比较。通过可靠性分析研究观察者间的一致性。使用组内相关系数（ICC）评估观察者之间的一致性。使用卡方检验独立性来确定两个名义变量之间是否存在显著关系（p <.05）。
正确评估牙槽骨骨折的比例为 96.9%，其次是根尖成熟度（92.7%）、根折（85.4%）、脱位损伤（76.5%）、冠折（76.2%）和软组织损伤（50%）。考虑到所有参数，12 名牙医给出的答案在软组织损伤方面存在统计学差异（p <.05）。
参与者的评分准确性很高，彼此之间相互一致，除了识别软组织损伤外。这种新的指数有利于实际和可靠地记录牙科创伤病例的数据。
