CONTEXT
Performing surgery on the anterior mandible could harm the mandibular incisive canal (MIC). To prevent it, preoperative radiographic assessment is essential.
AIMS
Aim of our study was to examine the visibility and presence of the MIC along with measurement of the length of MIC by utilizing cone-beam computed tomography (CBCT).
SETTINGS AND DESIGN
Images from 50 subjects, ranging in age from 20 to 60 years, who had their mandibles examined by CBCT were taken from the archive.
METHODS AND MATERIAL
Reconstructed images included cross-sectional and panoramic views. The canal's visibility was obtained from the mesial to the mental foramen and finally to the incisal extension. The shortest distance between the mesial and distal portions of the canal was determined to be the length of the MIC.
STATISTICAL ANALYSIS USED
To analyze independent samples, -tests were employed.
RESULTS
In 40 cases (80%), the visibility of MIC was seen as bilateral, and in 10 cases (20%), as unilateral. The visible length among the population ranged from a minimum of 0.00 to a maximum of 25.25 mm, with an average of 15.37 ± 5.59.
CONCLUSIONS
Future research could utilize the differences in prevalence with respect to gender and visibility as a point of reference.
背景
在下颌骨前部进行手术可能会损伤下颌切牙管（MIC）。为防止这种情况发生，术前影像学评估至关重要。
目的
我们研究的目的是利用锥形束计算机断层扫描（CBCT）检查MIC的可视性和存在情况，并测量MIC的长度。
设置与设计
从存档中获取50名年龄在20至60岁之间、其下颌骨接受过CBCT检查的受试者的图像。
方法与材料
重建图像包括横断面视图和全景视图。从近中到颏孔，最后到切牙延伸部观察管道的可视性。确定管道近中部分和远中部分之间的最短距离为MIC的长度。
所用统计分析
采用t检验分析独立样本。
结果
40例（80%）中，MIC的可视性为双侧，10例（20%）为单侧。人群中可见长度范围为最小值0.00至最大值25.25毫米，平均为15.37±5.59。
结论
未来的研究可以将性别患病率差异和可视性差异作为参考点。
