Abstract
The mandibular incisive canal (MIC) is a neural canal containing one of the lower branches of the inferior alveolar nerve, called the mandibular incisive nerve, which can get damaged and cause complications during the removal of bone from the interforaminal region. The aim of this study was to determine the effect of the inversion filter (IF) on improving the visibility of MIC as compared to the original images. In this retrospective, descriptive, analytical study, 343 samples of digital panoramic radiography were examined. The images were analyzed with and without IF. The frequency and confidence intervals (CIs) of identifying MIC were used to determine its visibility, both with IF and in the original images. Besides, the difference between the maximum and minimum diameters of the canal as well as the distance from MIC to the alveolar crest and to the mental foramen were examined. For statistical analysis, McNemar's test and the paired t-test were used, and the concordance was calculated using the kappa coefficient. No significant differences were found in the prevalence of the incisive canal, or in its unilateral or bilateral visibility between the original and filtered radiography in this study (p = 0.42 and p = 0.67, respectively). The absolute values of the interval difference between MIC and the mental foramen, the maximum and minimum diameters of MIC, and the distance from MIC to the alveolar crest were statistically significant between the filtered and original radiography, although the difference was clinically unimportant. The use of IF produced results similar to the original radiography; its application neither increased the clarity nor improved the visibility of the incisive canal.
Highlights
The mandibular incisive canal (MIC) is a neural canal containing one of the lower branches of the inferior alveolar nerve, called the mandibular incisive nerve.[1]
No significant differences were found in the prevalence of the incisive canal, or in its unilateral or bilateral visibility between the original and filtered radiography in this study (p = 0.42 and p = 0.67, respectively)
cone-beam computed tomography (CBCT) is considered to be more accurate than panoramic imaging for observing anatomical structures in the oral cavity,[8] its radiation dosage and costs are higher than in the case of panoramic radiography,[9,10,11] so it would be very practical to develop a technique to improve the observation of MIC in panoramic radiography
Summary
The mandibular incisive canal (MIC) is a neural canal containing one of the lower branches of the inferior alveolar nerve, called the mandibular incisive nerve.[1] It was Olivier who first described it as an extension of the lower alveolar canal.acc.[2] The mandibular incisive canal, which supplies the nerves of the anterior teeth of the mandible,[3] sometimes extends to the midline, and in some cases, ends up between the canine region and the premolar region.[4] Various studies reported different frequencies for the observation of MIC.[2,5,6,7] In certain studies, MIC was detectable in only 15% of panoramic images, and only 1% of the images had good resolution, whereas in cone-beam computed tomography (CBCT), it was detectable in 93% of cases.[5].
