Objective: Comprehensive knowledge about the anatomy of the surgical site is an important prerequisite for any surgical procedure. This study aimed to assess the prevalence, position and anatomical characteristics of mandibular incisive canal (MIC), lingual foramen (LF) and anterior loop of the mandibular canal (ALMC) in an Iranian population using cone beam computed tomography (CBCT). Materials and Methods: This study was conducted on 103 patients who underwent CBCT prior to implant placement. The CBCT scans of patients were evaluated by two observers to determine the visibility and length of MIC, LF and ALMC. The buccolingual inclination of MIC at the initiation point of canal and canal path were also studied. Results: The prevalence of MIC, LF and ALMC was 90%, 76% and 84% on CBCT scans, respectively. The mean length of MIC and ALMC was 7.5mm and 1.2mm, respectively and the mean width of LF was 0.9mm. The MIC had a buccal inclination at the initiation point and approximated the lingual plate as extended towards the midline. Analytical statistics including independent samples t-test, paired samples t-test, ANOVA analyses were applied. Conclusion: Considering the high prevalence of MIC, ALMC and LF and wide range of MIC (1.2mm to 20mm) and ALMC (1mm to 9.9mm) length, CBCT is recommended for patients prior to surgical procedures in the anterior mandible to determine the exact location of these anatomical structures.

The mandibular canal is an anatomic structure that extends bilaterally from the mandibular foramen to the mental foramen. Objective: To identify the presence, extension, and length of the mandibular incisive canal with a cone-beam computed tomography, and to determine correlations with the positioning of the mental foramen and mandibular canal in a selected Brazilian Amazon population. Material and methods: The measurements of the incisive canal that ends at the mandible’s lower buccal and lingual border, at its initial and terminal portions, were obtained from 95 odontological examinations using cone-beam computed tomography. These measurements were compared with the measurements of the distance between the mandibular canal ending at the same cortices in 2 distinct regions at the mental foramen region. Pearson’s correlation test was used to establish a relationship between these measurements. Results: The mandibular incisive canal’s bilateral identification mean age was of 44.29 ± 11.04 y and the mean length was 10.38 ± 4.01 mm. Moderate correlations were found between the measurements of the mandibular incisive canal, mental foramen, and mandibular canal. Conclusion: The mandibular incisive canal can reach the region of the median line, and it did not present differences between the genders or for the length and distance of the mandibular incisive canal to the cortices ending at the mandible base.

AIM: The purpose of the study was to measure and compare the prevalence of mandibular canal (MC) location variations in regard to mandibular first molars in both genders at different age groups. METHODS: A retrospective study was performed on 80 cone-beam computed tomography scans. Distance between MC and apical apices of first molars, buccal and lingual cortical plates was measured in both sides. RESULTS: 80 scans with 160 sides were analyzed. Distances was measured bilaterally for all scans with mean (5.22 ± 0.77) in men versus (4.1 ± 0.7) in women at group age 31–40 apical to apices of first molars. The mean was (3.77 ± 0.62) in men versus (2.81 ± 0.47) in women at same age group at buccal side, lingually the mean was (4.02 ± 0.67) in men versus (3.67 ± 0.26) in women in the same age group. CONCLUSION: Our study showed that there were decrease in measurements in older age group in both genders and in female groups more than male groups but with no statistical significant difference.
