One of the anatomic structures in the mental interforaminal area is the mandibular incisive canal (MIC). Using various manipulation tools in the digital system may affect the visibility of MIC.
The purpose of this study was to assess the effect of inversion filter (IF) on the visibility of mandibular incisive canal in panoramic radiographs.
In this cross-sectional study, 2580 digital panoramic images of 18 to 70-year-old patients were inspected for presence of MIC. Visibility of MIC and extension of the canal were registered separately on each side using IF and conventional mode. Data were analyzed by Kappa test using SPSS version 20 software. A probability value of P < 0.05 was considered statistically significant.
There was no significant differences between IF and conventional mode regarding visibility of MIC (P > 0.05).
Although using IF caused improved visibility of MIC, the difference with conventional mode was not statistically different.
颏孔间区的解剖结构之一是下颌切牙管（MIC）。在数字系统中使用各种操作工具可能会影响下颌切牙管的可视性。
本研究的目的是评估反转滤镜（IF）对全景X线片中下颌切牙管可视性的影响。
在这项横断面研究中，检查了18至70岁患者的2580张数字化全景图像，以确定是否存在下颌切牙管。使用IF和传统模式分别记录每侧下颌切牙管的可视性和管道延伸情况。使用SPSS 20版软件通过Kappa检验分析数据。P < 0.05的概率值被认为具有统计学意义。
在MIC的可视性方面，IF与传统模式之间没有显著差异（P > 0.05）。
尽管使用IF可提高MIC的可视性，但与传统模式的差异无统计学意义。
