This study was aimed at identifying the wormian bone and their overall incidence in respect to their number and location in the region of Andhra Pradesh. Overall incidence of wormian bones was more in female (47.72%) than in male skulls (41.66%). They occurred more frequently at lambdoid suture (38%). Wormian bones along the coronal suture, Bregma and Asterion were seen only in male skulls, while intra-orbital wormian bones and wormian bones at Pterion were seen only in female skulls. This study concludes by stating that, there exists a moderate degree of sexual dimorphism among the wormian bones with respect to overall incidence, number and location.
