Relationship of inferior alveolar canal to the apices of lower molar teeth radiographically


The mandibular foramen (MF) is located on the medial surface of the ramus of mandible, leading into the inferior alveolar canal (I.A) which accommodates the inferior alveolar neurovascular bundle, in this study sixty periapical radiographs were taken to examine the approximity of the canal to mandibular molar apices, and it has been found the mean distance of mesial and distal roots of molar teeth to the canal as follows, for the first molar were (5.63), (6.16) respectively. While for the second molar were (2.3), (3.08) respectively, the recorded results reinforce the cases neuralgia, and numbness due to injury of (I.A) canal particularly in complicated extraction for the lower second molar teeth
