THE RELIABILITY OF DENTAL PULP IN HUMAN BLOOD GROUP IDENTIFICATION

Abstract

Dental tissues play a very Important role for forensic purposes, because it is the hardest of all human tissues and can be preserved for a prolonged duration even subsequent to death, The aim of the this study was to determine the ABO blood grouping from the pulpal tissue of extracted teeth and to correlate the same with blood group details obtained from the study subjects.

This descriptive cross sectional study was conducted on 50 subjects. Blood group was determined on blood which was obtained from blood already taken for Hepatitis screening. To determine association Goodman Kruskal Gamma test was applied between blood sample from dental pulp and control in SPSS 20.0.

Out of total participants, 29(58%) were females and 21(42%) were males. The mean age was 25.565.17 years, ranging from 18 to 38 years. All the correlation (association) was very high and statistically significant. Overall correlation was very (r=0.99, P=0.00). The correlation was ranging from 0.87(blood group B) to 1.00 (blood AB & O). Similarly, the correlation among Rh+ and Rh- was also very high i.e. 0.98 and 0.88 respectively and was statistically significantly.

The finidngs of this investigation showed that there is high correlation of the pulpal blood group with venous blood. So the blood group of this population can determined from dental pulp.
