Study of Wormian Bones In Relation To the Size of the Skull with an Aim for Sexual Dimorphism
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 8
Abstract
Bones are population-specific.Racial,regional and gender variation exists in skeletal components of bones .The present study was undertaken to observe the relationship between the cranial index and the incidence of wormian bones and to study the sexual dimorphism with regards to wormian bones inadult human dry skull.This study included 103 dried human skulls taken from the department of anatomy, GVPIHC&MT, Visakhapatnam.The bones were separated into male and female and divided into three categories based on their cranial index i.e. normal (CI<81), brachycephalic (CI 81-93) and severely brachycephalic (CI >93).Out of 103 skulls, 73 (70.8%) showed sutural bones and the most frequent site was asterion (56%). Severely brachycephalic skulls(CI >93)was found to havemore number of wormian bones. Sexual dimorphism with regards to wormian bones exists in skulls as observed thatthe male skulls had more number of wormian bones (51.4%) than female (19.4%) with a P value <0.01which proves to be statistically significant .A knowledge of distribution of wormian bone in the adult human dry skulls is useful for clinicians and radiologists in studying radiographs to avoid interpreting it as fracture.
