Evaluation of salivary DNA obtained from dental prosthesis and its applicability in forensic investigations

Abstract Aim This study evaluated the salivary DNA obtained from dental prosthesis after a period of storage and its applicability in human identification. Material and methods In first phase, DNA was extracted after a span of 1 week and 1 month from the dental prosthesis dipped in whole saliva for 15 min. It was followed by PCR and electrophoresis. In second phase, from extracted DNA samples 15 STRs (short tandem repeats) of human genomic DNA were amplified via polymerase chain reaction. Results & conclusion DNA isolated from saliva stained dental prosthesis after a period of storage and the techniques employed are adequate for further forensic analysis.
