Comparative Study of Incidence of Wormian (Sutural) Bones in North and South Indian Population

Abstract

1189 Non-Pathological dried adult crania from north and south Indian states (NI & SI) are studied and observed that Incidence of sutural bones (SB) were more in female crania of all 3 stutures i.e. coronal, sagital & lambdoid. A) In NI cranial study coronal suture of female crania had 8.76% of SB but in males crania it was 6.47%. In sagital suture 18.72% SB while in male crania had 17.45%. Moreover in lambdoid suture also 168.72% was observed in female crania while male crania had 122.12%. Similarly b) in SI crania also exhibit more incidence of SB in female crania all three sutures - coronal suture of female crania had 8.39% while male crania had 7.7%. In sagital suture of female crania had 13.2% while male crania had 9.47% moreover lambdoid suture of female crania of SI had 220.09% and male crania had 171.22%. c) during regional study of male crania of NI were compared with SI crania - of male crania of coronal suture of NI had incidence of SB were 6.47% while SI had 7.71% SB, but SB at sagital suture were more in NI crania 17.45, while SI crania of suture had 9.47% which was statistically highly significant (P < 0.01) similarly lambdoid suture of NI crania had 122.35% and SI crania had 171.21, during comparison of regional study of female crania of NI and SI. In coronal suture of SI female had 8.39% and NI female had 8.76% similarly sagital suture also had 18.55% of SB in NI female while SI female had 13.28%, but lambdoid suture of SI female had 206.94% and NI female crania had 168%. These findings are helpful to the anatomist, anthropologists and medicolegal expert to differentiate sexual diamorphism and comparison of India as whole or regionally. Above all to the clinician, who may confuse the incidence of SB as fractures.
