 Abstract: The retromolar foramen (RMF) is one of the nonmetrical variants of the mandible (Ossenberg, 1987). The dental practitioners should be aware of this variant and the possible complications which may occur during anesthetic, surgical, and implantation procedures of the mandible .Indian adult dried human mandibles (150) were observed for the presence of retromolar foramen (RMF) or retromolar canal. Their gross morphological features were studied. These canals showed variations in location, length and diameter in relation to third molar.
