The present study aimed to assess the co-occurrence of taurodontism in nonsyndromic cleft lip and palate (NSCLP) patients in a subset of Indian population using cone beam computed tomography (CBCT). The study was a retrospective case-control kinds assessing 1500 CBCT scans over a period of 2 years; 67 scans out of 1500 showed cleft lip and palate (CLP). After fulfilling the inclusion and exclusion criteria, 38 subjects out of 67 comprised the case group; 80 randomly selected subjects constituted the control group. The first and second permanent molars in both the arches (8 teeth) of each subject were assessed for the presence and severity of taurodontism using the objective criteria. Statistical analysis was done using the χ test. Inter and intraobserver agreement was evaluated by Kappa statistics. 71.05% subjects showed taurodontism in case group, while 45% subjects showed its presence in control group; results being significant for both the groups. However, the comparison of number of teeth with taurodontism in the 2 groups came out to be statistically insignificant. Also no significant association of taurodontism was seen with gender or the different types of cleft ( = .437). Hypotaurodontism was the most prevalent type. There was a higher prevalence of taurodontism in both groups which had been underestimated in the previous studies. This emphasizes the significance of the use of CBCT in detection of dental anomalies which would otherwise go undetected.
本研究旨在使用锥形束计算机断层扫描 (CBCT) 评估印度人群中非综合征性唇腭裂 (NSCLP) 患者中 taurodontism 的共现情况。该研究是一项回顾性病例对照研究,评估了 2 年内的 1500 例 CBCT 扫描;在 1500 例中,有 67 例显示唇腭裂 (CLP)。在满足纳入和排除标准后,67 例中有 38 例符合病例组;80 例随机选择的受试者构成对照组。使用客观标准评估每个受试者的两个弓中的第一和第二恒磨牙(8 颗牙)是否存在和 taurodontism 的严重程度。使用 χ 检验进行统计分析。使用 Kappa 统计评估了观察者间和观察者内的一致性。在病例组中,71.05%的受试者表现出 taurodontism,而对照组中有 45%的受试者表现出 taurodontism;这两个组的结果都有统计学意义。然而,两组中具有 taurodontism 的牙齿数量的比较在统计学上没有显著差异。taurodontism 也与性别或不同类型的裂隙无显著关联 ( =.437)。低 taurodontism 是最常见的类型。两组中 taurodontism 的患病率都较高,这在以前的研究中被低估了。这强调了在检测牙齿异常方面使用 CBCT 的重要性,否则这些异常将无法被发现。
