ABO Blood group Detection in Teeth from Cadaver: A Modified Absorption-Elution Technique

Abstract

In a medicolegal investigation, a forensic pathologist, sometimes known as a forensic dentist, works hand in hand with a police officer to determine an individual's identification as a source of information. The blood group might be essential in establishing the victim's identification and the culprits who committed the crime in medico-legal investigations. Because dental tissues are hard of all human tissues and may be conserved for a long time even after death, they are significant for forensic purposes. The main goal of this study was to use the Adsorption-Elution method to detect blood group and Rhesus factor from soft and hard tissue of the tooth as biological evidence and also determine the ABO blood grouping from patients and cadavers in forensic investigation. The results showed, that there was a strong positive matching of the blood grouping with the coagulation of the tooth specimen.
