1189 non-pathological dried adult crania were studied from north and South India. The angles were measured by protractor after tracing on butter paper. In the study of sexual dimorphism the angle between sagital and lambdoid suture was significant (P<0.05) on left side and the angle between two limbs of lambdoid suture was significant (P<0.01).In the regional comparison of Male crania of NI with male crania of SI. (1) The angle between coronal suture shown significant P value (P<0.01). (2) Angle between sagital and lambdoid suture left side was highly significant in P value (P<0.01). (3) The angle between two limbs of lambdoid suture shown significant P value (P<0.01). In the regional study of female crania of SI and NI was compared (a) Shown highly significant P value (P<0.01) in angle of coronal suture. (b) Angle between sagital and lambdoid suture on left side shows significant P value (P<0.03). (c) Angle between two limbs of lambdoid suture of female crania of north and SI shown significant P value (P<0.01).(a)The logistic regression equation study of angle between two limbs of lambdoid suture with cranial index classified 73.8% of crania of NI and 67% in SI. (b) In the regional comparison of male crania of NI and SI classified 71.7% and female crania of NI and SI classified 75.1%. This study could not be compared with previous studies as no data is available in English literature but these findings are quite helpful to the anatomist, anthropologist and medicolegal expert.

Abstract


1189 non-pathological dried adult crania were studied from north and South India. The angles were measured by protractor after tracing on butter paper. In the study of sexual dimorphism the angle between sagital and lambdoid suture was significant (P<0.05) on left side and the angle between two limbs of lambdoid suture was significant (P<0.01).In the regional comparison of Male crania of NI with male crania of SI. (1) The angle between coronal suture shown significant P value (P<0.01). (2) Angle between sagital and lambdoid suture left side was highly significant in P value (P<0.01). (3) The angle between two limbs of lambdoid suture shown significant P value (P<0.01). In the regional study of female crania of SI and NI was compared (a) Shown highly significant P value (P<0.01) in angle of coronal suture. (b) Angle between sagital and lambdoid suture on left side shows significant P value (P<0.03). (c) Angle between two limbs of lambdoid suture of female crania of north and SI shown significant P value (P<0.01).(a)The logistic regression equation study of angle between two limbs of lambdoid suture with cranial index classified 73.8% of crania of NI and 67% in SI. (b) In the regional comparison of male crania of NI and SI classified 71.7% and female crania of NI and SI classified 75.1%. This study could not be compared with previous studies as no data is available in English literature but these findings are quite helpful to the anatomist, anthropologist and medicolegal expert.
