PURPOSE
The aim of this study was to evaluate the prevalence of bifid mandibular canals (BMC) by cone beam computed tomography (CBCT).
MATERIALS AND METHODS
We examined CT scans from 300 patients both male and female, aged 25 to 87 years. The subjects were divided into groups according to gender, male group (MG) and female group (FG) as well as subgroups according to the side, right (R) and left (L). Tomographic acquisitions were performed on the device I-Cat ® Classic. Image analysis was performed on the XoranCat ® software of the equipment itself, aided by image filters associated with transverse, oblique, and panoramic reconstruction cuts for analysis of the BMC. The results were displayed as descriptive analysis of the values and comparisons between factors were performed using ANOVA at a significance level of 95 %.
RESULTS
BMC was observed in 80 cases (26.67 %), of which, 39 (48.75 %) were in males and 41 (51.25 %) in females; no difference was seen between genders, neither by affected side, although the right side was more frequently affected (66.67 %) when both genders were combined.
CONCLUSION
The prevalence of BMC is significant and should not be overlooked.
目的
本研究旨在通过锥形束计算机断层扫描（CBCT）评估双下颌管（BMC）的患病率。
材料与方法
我们检查了300例年龄在25至87岁之间的男性和女性患者的CT扫描图像。受试者根据性别分为男性组（MG）和女性组（FG），并根据左右侧分为亚组，即右侧（R）和左侧（L）。断层扫描采集在I-Cat®Classic设备上进行。图像分析在设备本身的XoranCat®软件上进行，借助与横向、斜向和全景重建切片相关的图像滤波器来分析BMC。结果以数值的描述性分析呈现，并使用方差分析（ANOVA）在95%的显著性水平下对各因素进行比较。
结果
在80例（26.67%）中观察到BMC，其中男性39例（48.75%），女性41例（51.25%）；性别之间未见差异，按患侧分析也无差异，尽管在合并两性时右侧更常受累（66.67%）。
结论
BMC的患病率较高，不应被忽视。
