Age estimation of an Indian population by using the Kim′s scoring system of occlusal tooth wear

Abstract

Context:Age is one of the prime factors employed to establish the identity of an individual and the use of teeth for this purpose has been considered reliable. Tooth wear is widely accepted as a physiological consequence of aging and evaluation of tooth wear can be a simple and convenient tool to estimate age in adults.Aims:The present study was conducted to record the degree of tooth wear among Indian adults and to estimate their ages from the degree of tooth wear based on Kim's scoring system.Materials and Methods:Dental stone casts of 120 participants were used to assess the degree of occlusal tooth wear based on the criteria given by Kim et al.Statistical Analysis Used:The age of all subjects was estimated based on these scores using multiple regression analysis function.Results:The degree of tooth wear showed a significant positive correlation with age in each and every examined tooth of both males and females. The predicted age was within ± 5 years of actual age in 70% of males and 68.3% females, and within ± 3 years of actual age in 50% of males and 50.1% of females.Conclusions:Kim's scoring system has proven to be a useful tool in estimation of age using occlusal wear in an Indian population with a high level of accuracy in adults.

Tooth wear as an indicator of acculturation process in remote Amazonian populations

“…There are several well accepted indices in the literature to measure tooth wear, and to compare different population groups through different indices can lead to wrong conclusions [15]. For example, in Chinese Malaysian and Indian populations, a high correlation was found between tooth wear and age [9,10], similar to that seen in Xingu indigenous populations. Nevertheless, another measurement index was used, in addition to different selection criteria.…”

“…Dental wear can be an effective tool for estimating age in different populations [9][10][11]. As dental hard tissues undergo progressive loss due to mechanical and/or chemical wear and are not replaced [12,13], quantifying dental wear to estimate chronological age is valid, especially, after development of the dentition and growth cessation.…”

Morphology and Volume of Maxillary Canine Pulp Cavity for Individual Age Estimation in Forensic Dentistry

“…Gustafson first proposed in 1950 to use six characteristic changes of age-related teeth for age estimation, but there were some defects in the age structure and statistical inference of the samples. Subsequently, many scholars use dentin translucency, cementum ring structure, amino acid racemization, and modified Gustafson method for age estimation (Singh et al, 2014;Shrigiriwar & Jadhav, 2013;Vandevoort et al, 2004;Telang et al, 2014;Gilmore & Grote, 2012). However, these methods are complicated, require professionals to use special equipment and to spend a lot of time and financial resources, and sometimes even need to pull out the teeth.…”

Restoration of the Occlusal Vertical Dimension with an Overlay Removable Partial Denture: A Clinical Report

“…1 However, in terms of the physiological question, the amount of tooth wear can be used to estimate age with a high level of accuracy. 1,2 With respect to the area that suffers the largest amount of loss, anterior tooth wear is greater than that in the posterior region, involving not only physiologic, but also esthetic alterations. 3 The body response to tooth wear seems to have two paths according to the alterations in the occlusal vertical dimension (OVD).…”

“…The type of food ingested can also have an effect, as harder, more acidic foods can accelerate tooth wear . However, in terms of the physiological question, the amount of tooth wear can be used to estimate age with a high level of accuracy . With respect to the area that suffers the largest amount of loss, anterior tooth wear is greater than that in the posterior region, involving not only physiologic, but also esthetic alterations .…”
