The Bony plates stretch over the mylohyoid groove of the mandible either completely or partially is called as mylohyoid bridging. Presence of such mylohyoid bridging may compress the mylohyoid neurovascular bundle which produces the neurological or vascular disorders.__ampersandsignnbsp; This study is clinically important for Dental surgeons, anesthetists, anthropologists. Objectives: To study the site, extension and location of the bony bridging of mylohyoid grooves on right and left sides of mandibles in north coastal Andhra population of south India and compare the present study results with those of previous studies. Methods: The present study is conducted on 60 macerated mandibles, which are available in the osteology section of department of anatomy. In each mandible we have examined both medial sides of the mylohyoid grooves and their bony bridging. Results and Conclusion: In the present study mylohyoid groove bony bridges were found as incomplete or partial type on total 4 sides (2 proximal and 2 distal types) out of 120 sides of 60 mandibles (incidence as 3.33%). All bony bridges were seen unilaterally, No cases were found as complete bony bridges.
