Abstract
Aims:This study aims to verify the applicability of modern dental technologies and their related principles of use to the forensic sciences in the field of personal identification.Background:Personal identification has always had a major role in many legal and administrative actions regarding both living and death beings. The techniques used are much less advanced than the technologies potentially available.Objective:Modern technologies, available to the daily dental clinic practice, as intraoral scanners, combined in particular to the specialist skill in orthodontics, can help redefine the methods of personal identification according to the levels of accuracy, trueness and feasibility greater than those applied in traditional forensic dentistry.Methods:23 corpses (12F;11M) have been selected for intraoral scanning with the Carestream 3500®digital device. The superimposition of initial and late digital models, digital models and radiographs (orthopantomography and full mouth periapical films) has been evaluated to verify the stability of some structures as palatal rugae after death and to assess intraoral scanning as a successful comparative method between antemortem and post-mortem records (digital models or radiographs). Obtained results were subjected to statistical analysis by the t-student test and X-square test with Yates correction (p<0.05).Results:After death, palatal rugae significatively change especially in mouths with restorations/prosthesis/missing teeth. The percentages of correct matching between scans and radiographs are very higher (up 90%; p<0.05).Conclusion:This study has been set up to study and develop new, reliable and fast methods of personal identification that can surpass many of the issues seen with the other techniques by a modern rugoscopy, a modern radiographic-digital comparison and virtual oral autopsy.
Highlights
Orofacial pain, a term that can be defined as pain that related to the oral and facial region remains one of the most complained dental problems [1 - 3]
Validity and reliability testing of the current questionnaire revealed that the questionnaire was proven to be valid and reliable
An epidemiology study conducted by Shetty et al, (2015) in 2200 patients who visited the Oral and Maxillofacial Surgery Departments of Sri Rajiv Gandhi College of Dental Sciences and Hospital in Bangalore, India, from the period of March 2010 to April 2011 revealed that deep somatic oral pain was the most common type of orofacial pain experienced by orofacial pain patients
Summary
A term that can be defined as pain that related to the oral and facial region remains one of the most complained dental problems [1 - 3]. A review study about the prevalence of orofacial pain confirmed that 10% of the adult population experienced facial pain [4]. Orofacial pain remains one of the most complained dental abnormalities that resulted in the limitation of the jaw and facial activities of the sufferer. A simple yet effective questionnaire that can be used by dental professionals to evaluate the level of the jaw and facial activity limitation of orofacial patients is needed
