ABSTRACT:
To determine the prevalence of retromolar foramen in human mandibles .This survey was conducted to test the incidence of retromolar foramen in human mandibles and its clinical significance. The retromolar foramen (RMF) is a rare anatomical structure situated in the retromolar fossa behind the third molar tooth and it allows the passage of neurovascular bundle that contribute to the nutrition and innervations of the pulp and periodontium of the lower teeth. The presence of retromolar foramen and canal and its contents have great clinical significance and can be injured in various surgical procedures like flap lifting, bone tissue for autologous bone grafts, osteotomy for the surgical extraction of third molar, placement of osseointegrated implants for orthodontic or in saggital split osteotomy surgeries .This survey was done to assess the prevalence of retromolar foramen in human mandibles and its clinical significance and to create proper awareness among surgeons to prevent the retromolar foramen from damage during surgeries.
