Prevalencia y características del canal incisivo mandibular en CBCT

Abstract

Background: The MIC is an anterior extension of the mandibular canal of the mental foramen that contains a neurovascular bundle. CBCT allows its assessment to avoid alterations in its structure. Objetive: Determine the prevalence and characteristics of the mandibular incisor canal using CBTC. Methodology: A descriptive and observational research was carried out. The sample consisted of 93 tomographies taken at “Innova Radiografía Dento Maxilo Facial” of the city of Cuenca from 01-10-16 until 30-09-17. The radiology center database was reviewed and the analyzed the CBTC's using the software iDixel 7.0.0.1, the information was processed with the SPSS V.23. Results: The prevalence of MIC was 95.7% and was visualized mainly in males (97.5%). In 80.9% of patients, the position of the canal is bilateral, when unilateral it prevails on the left side of the jaw (12.4%). In both sexes, the bilateral channel is more frequent, especially in women (88%). Unilateral positions, either right or left, predominate in men (12.8% and 15.4%). The average dimensions of the MIC were: (right / left) length: 8.59 ± 3.40 mm / 9.07 ± 3.30 mm, vertical maximum diameter: 1.88 ± 0.59 mm / 1.93 ± 0.54 mm and anteroposterior maximum diameter: 2.02 ± 0.54 mm / 2.07 ± 0.53 mm). Conclusions: The prevalence of the mandibular incisor channel is high, with morphological characteristics in our population, which is why it is necessary to identify and assess it using cone beam computed tomography
