Abstract The aim of the current study was determine the distance between mandibular canal (CDI) and lingual (TL), labial (V) and basal cortical bone (RB) in four mandibular body areas. Ten mandibular bones showing premolar and molar edentulous region was used. They were assessed by Conventional Spiral Tomography (Cranex TOME multifuctional unit, Soredex, Finland) and a direct visual exam following osteotomy. Measures were made from CDI to TL, TV and RB; at second premolar, first molar, second molar and third molar level. Gotten results were assessed by ANOVA, Kolmogorov-Smirnov and Levene tests that showed homogeneity among specimens measures and Tomographies (p>0.05). ANOVA and Kruskal-Wallis were used to refer measures where CDI diameter and the distance to TL were constant in the four mandibular body areas (p>0.05). CDI diameter showed a rank from 2.3mm to 2.6mm and a distance of 2.5mm a 2.8mm to TL. The distances to RB and TV showed statistically significant differences (p<0.05). The current study shows that CDI diameter remains constant and CDI runs mandibular body near to TL
