Objective: To evaluate the frequency of accessory mental foramen (AMF) and anatomical variants of the mental nerve anterior loop using cone-beam computed tomography (CBCT) in a Peruvian population. Material and methods: This retrospective cross-sectional study evaluated 80 hemi-mandibles from 40 subjects using CBCT. The sample included 38 females and 42 males, with an average age of 25±4.45 years. A 3D multi-planar reconstruction was performed to identify the location and presence of accessory mental foramina, their morphological characteristics (oval or circular), their position with respect to the mental foramen (MF), anterior loop (AL) path and other anatomical landmarks including lengths and angles. Statistical analyses included chi square and t-tests. The significance level was p<0.05. Results: The frequency of AMF was 17% and the average distance AL-MF was 4.76±1.97mm. The measurements of the anterior border of AL and MF to the inferior mandibular border showed significant differences according to the sex (p<0.001 and p=0.009, respectively). Conclusion: The AMF prevalence was approximately 17%. There is no association between the AMF position and its morphology, sex or side evaluated. The distances from the anterior border of the AL and from the inferior border of the MF to the inferior mandibular border were greater in males. These findings should be considered when planning implant or mini-implant placement in this region.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.
