Abstract
Background: There is a high failure rate of endodontic treatment in the mandibular incisors due to insufficient knowledge of the morphology.
Aim: The aim of this study was to analyze the root canal morphology in mandibular incisor teeth in the North Indian subpopulation to improve the outcome of endodontic treatment.
Setting and design: A cross-sectional study was conducted at the OPD of a tertiary care institute.
Materials and methods: A total of 200 mandibular central incisors and 200 mandibular lateral incisors were selected from available cone-beam computed tomography examinations of 100 patients aged 18-79 years. They were evaluated for root canal system configuration and symmetry between right and left elements in the same individual.
Statistical analysis: Chi-square/Fisher's exact test was used to find the association between different study variables.
Results: For mandibular central incisors, type I Vertucci classification was present in 69% of cases, type II in 3.5%, type III in 18.5%, type IV in 2%, and type V in 7% of cases. For mandibular lateral incisors, type I was present in 70.5% of cases, type II in 4% of cases, type III in 19.5%, type IV in 2%, and type V in 4% of cases. There was no evidence of types VI, VII, and VIII. Symmetry of root canal morphology between left and right teeth was observed in 90% of central incisors and 93% of lateral incisors.
Conclusion: Type I Vertucci configuration was the most prevalent; however, the prevalence of other configurations is also evident. Therefore, endodontists should explore the morphology of these teeth carefully while performing root canal treatments.
背景：目的：本研究旨在分析北印度亚群下颌切牙的根管形态，以改善牙髓治疗的结果：一项横断面研究在一家三级医疗机构的手术室进行：从现有的 100 名 18-79 岁患者的锥形束计算机断层扫描检查中选取了 200 颗下颌中切牙和 200 颗下颌侧切牙。统计分析：统计分析：采用卡方/费舍尔精确检验来发现不同研究变量之间的关联：对于下颌中切牙，69%的病例属于 Vertucci I 型，3.5%的病例属于 II 型，18.5%的病例属于 III 型，2%的病例属于 IV 型，7%的病例属于 V 型。就下颌侧切牙而言，70.5%的病例中存在 I 型，4%的病例中存在 II 型，19.5%的病例中存在 III 型，2%的病例中存在 IV 型，4%的病例中存在 V 型。没有发现Ⅵ型、Ⅶ型和Ⅷ型。90%的中切牙和 93% 的侧切牙左右牙根管形态对称：结论：第一型 Vertucci 构型最常见，但其他构型也很常见。因此，牙髓病学家在进行根管治疗时应仔细研究这些牙齿的形态。
