VASCONCELLOS, Henrique Ayres de et al. THE ANATOMY OF THE LINGUAL FORAMEN CANAL AND ITS RELATED TO THE MANDIBULAR SYMPHYSIS. Rev. chil. anat. [online]. 2000, vol.18, n.1, pp.47-51. ISSN 0716-9868.  http://dx.doi.org/10.4067/S0716-98682000000100006.

We have measured alveolar and basal midsagittal cross-sections of the symphyseal area of the mandible to determine the relationships between the mandibular lingual foramen (MLF) and its canal to the anterior and posterior surfaces of the mandibular symphysis. The alveolar-basal length (A), the distance between the anterior end of the foramen canal and buccal (B1), lingual (B2), basal (C) and alveolar (D) surfaces of 116 midsagittal cross-sections (58 dentulous; 58 edentulous) of dried human mandibles were evaluted. The mean values of the length of the symphysis (A) were 31.87 ± 3.75 mm for dentulous and 23.08 ± 4.40 mm for the edentulous mandibles. The A measurements had the smallest coefficient of variation. The B1, B2, C and D measurements showed small differences between dentulous and edentulous mandibles but higher coefficients of variation. We established morphometric parameters for mandibular symphysis of brazilian mandibles that can be use in planning of oral surgery and implantology compared with other studies
