The present study aimed to perform a systematic review of the literature on the mandibular incisive canal (MIC) studies using cone-beam computed tomography (CBCT). Materials and Methods: A PROSPERO-registered systematic review (#42017056619) was conducted following the PRISMA statements. A search was performed in PubMed's Medline and Scopus databases, without date or language restrictions, using the algorithm {[(Interforaminal region) OR (mandibular incisive canal) OR (mandibular incisive nerve) OR (mental mandible) OR (anterior mandible) (cone beam computed tomography). Results: A total of 410 articles were found and 25 studies were selected. Geographically, the studies were distributed across 4 continents (South America, North America, Asia, and Europe). From 3084 CBCT exams, the number of female patients was slightly higher than male and the mean age ranged from 29.8 to 59.1 years. The mean prevalence of MIC was 89.6 ± 15.08% and bilateral occurrence was statistically significant (p <0 .0001). Diameter (0.45 and 2.5mm) and length (2.2 to 18.5mm) showed great variability among the included studies. Conclusion: In summary, the results of the present systematic review evidenced a high worldwide prevalence of MIC. There was no prevalence of MIC in relation to gender, and its presence was mainly related to adults between the fourth and sixth decades of life. In addition, great heterogeneity of methodologies was observed.
