Abstract

OBJECTIVES

The purpose of this study was to investigate the C-shaped root canal anatomy of mandibular second molars in a Korean population.

MATERIALS AND METHODS

A total of 542 teeth were evaluated using cone-beam computed tomography (CBCT). The canal shapes were classified according to a modified version of Melton's method at the level where the pulp chamber floor became discernible.

RESULTS

Of the 542 mandibular second molars, 215 (39.8%) had C-shaped canals, 330 (53%) had 3 canals, 17 (3.3%) had 2 canals, 12 (2.2%) had 4 canals, and 8 (1.7%) had 1 canal. The prevalence of C-shaped canals was 47.8% in females and 28.4% in males. Seventy-seven percent of the C-shaped canals showed a bilateral appearance. The prevalence of C-shaped canals showed no difference according to age or tooth position. Most teeth with a C-shaped canal system presented Melton's type II (45.6%) and type III (32.1%) configurations.

CONCLUSIONS

There was a high prevalence of C-shaped canals in the mandibular second molars of the Korean population studied. CBCT is expected to be useful for endodontic diagnosis and treatment planning of mandibular second molars.

摘要

目的

本研究旨在调查韩国人群下颌第二磨牙的C形根管解剖结构。

材料与方法

使用锥形束计算机断层扫描(CBCT)对542颗牙齿进行评估。在髓室底清晰可见的水平,根据改良的梅尔顿方法对根管形态进行分类。

结果

在542颗下颌第二磨牙中,215颗(39.8%)有C形根管,330颗(53%)有3根管,17颗(3.3%)有2根管,12颗(2.2%)有4根管,8颗(1.7%)有1根管。C形根管在女性中的患病率为47.8%,在男性中为28.4%。77%的C形根管呈双侧出现。C形根管的患病率在年龄或牙位方面无差异。大多数具有C形根管系统的牙齿呈现梅尔顿II型(45.6%)和III型(32.1%)形态。

结论

在所研究的韩国人群下颌第二磨牙中,C形根管的患病率较高。预计CBCT对下颌第二磨牙的牙髓病诊断和治疗计划有用。
