Awareness About Role Of Mt-Dna In Identification Among Dentists

Abstract

INTRODUCTION: Teeth are the hardest structures of the human body which are resistant to various adverse conditions such as incineration, trauma, etc.The mitochondrial Dna examines biological items of evidence from crime scenes to determine the mitochondrial DNA sequences from samples such as hair, bones, teeth. Typically, these items contain low concentrations of degraded DNA, making them unsuitable for nuclear DNA examinations.

AIM : The main aim of the study is to create awareness about the role of mt-Dna in identification among dentists.

MATERIALS AND METHODS: A questionnaire was distributed through an online google forms link to about 100 dental students. The questionnaire consisted of questions related to recent findings or updates, The results were collected from google forms  and the data was analysed using SPSS version 27.

RESULTS: 76.42% of the total population agreed that teeth serve as a source of DNA, 23.58% of total population disagreed that teeth do not serve as a source of DNA. Among the total population 71.70% responded that mt-Dna helped in investigation,and  28.30% responded that mt-Dna does not help in investigation. Out of 100 participants,47 participants responded yes and 11 participants responded No among females. And 37 participants responded yes and 14 participants responded no among males. P value= 0.000 (<0.05 )  and it was  statistically  significant, association between gender and their perception that  teeth serve as a source of DNA.

CONCLUSION : Mitochondrial dna plays an important role in dentistry, but the knowledge and practice towards mitochondrial dna is less.
