Abstract
The aim of the present study was the determine the location of the mental foramen and accessories, their relationships with the alveolar and basal rims found in Peruvians adults. A descriptive, transverse and retrospective study was carried out. The sample was composed of 100 cone beam CT scans of patients, between the ages of 20 to 55 years of age, these patients were attended at the clinic of the Faculty of Dentistry of Mayor National University of San Marcos UNMSM. Were considered tomograms of mandibular dentate patients taken during 2015, classified according to age and sex, identifying in them the location of the mental foramen and accesories in relation to a lower tooth, according to the classification of Al Jasser- Nwoku.The distance of the mental foramen on the left side to the alveolar ridge had an average of 12.62 mm and on the right side it had a mean of 12.90 mm and the distance from the mandibular ridge on the left side showed an average of 14.14 mm and on the right side was 13.91 mm. The relationship of the mental foramen to the teeth was located below the second mandibular premolar. The 14% presented accessory hole, predominating position 4 (at the level of the second premolar).
