Article
Estimating stature is an important step in reconstructive identification of skeletonized and dismembered human remains. While numerous body parts such as the skull and long bones have been used for the purpose, the dentition has seldom been applied. The present study has ventured to ascertain the usefulness of tooth crown measurements in stature pr...
Article
The third molars are one of few useful predictors for assessing the degree of maturity in adolescence and young adulthood. It has application in age estimation in the age group of 14-23 years, in general, and in juvenile/adult status prediction, in particular. Using a 10-stage grading of third molars, Gunst et al. developed regression formulae on a...
Article
Accurate sex prediction of skeletonised human remains excludes one-half of the population, enabling a more focussed search of missing persons' files. The skull is useful in sex assessment of skeletonised remains; however, its fragmentation precludes the use of all conventional craniofacial markers. The frontal bone may be recovered intact in fragme...
Article
Pulp/tooth area ratio (PTR) method of adult dental age estimation has been examined on few tooth types. We assessed the lateral incisor (LI) and first premolar (PM1) in addition to canine (C) - alone and in combination. Periapical radiographs from 61 Indians aged 21-71 years were examined. PTR of LI produced the best age correlation (r = -0.395) fo...
Article
Radiographic dental age estimation methods are viable in the living and deceased. One such method [Kvaal et al. Forensic Sci Int 1995;74:175-85] quantified secondary dentinal deposition indirectly through measurements of tooth and pulp lengths and widths. The method is untested on non-European populations and our objective was to assess its accurac...
Article
Teeth are useful indicators of age-at-death and non-destructive methods ensure preservation of dental evidentiary material which could be used for court presentation.

Odontometric sex assessment is considered a useful adjunct to more robust predictors such as pelvic and cranial bones, and discriminant function analysis (DA) has been widely applied in dental sex assessment. Logistic regression analysis (LRA) is considered a better alternative, although still untested in odontometric sex prediction. This study exa...
Article
Predicting 18 years of age can be crucial in forensic contexts. The third molar is the only tooth developing during this chronological period and has been used to estimate minority/majority status (</≥18 years). Conventionally, Demirjian's grading has been used to assess third molar development although the method was not originally intended for ev...
Article
The dentition's use in sex assessment has been explored and advocated owing to its strength and resistance to peri- and postmortem insults. Among the teeth, canines have shown the greatest sexual dimorphism; they are also known for greater resistance to pathological alterations and trauma. These factors have prompted some researchers to explore its...
Article
Demirjian's grading of tooth calcification is widely used to assess age of individuals with developing dentitions. However, its application on numerous populations has resulted in wide variations in age estimates and consequent suggestions for the method's adaptation to the local sample. Conventionally, Demirjian's method utilized seven mandibular...
Article
Assessment of age from the dentition constitutes an important step in constructing an identity profile of the decedent. Dentinal translucency is one of the morpho-histologic parameters considered best for dental age estimation, not only in terms of accuracy but also simplicity. By convention, translucency has been measured using calipers. Computer-...
Article
In India, age estimation of living individuals is gaining importance, particularly in cases of child labour, ascertaining majority status and to assess disputed age in criminals. Previous studies on adult age prediction in Indians have focused on histological parameters, which are invasive in nature and not feasible in the living. Methods for age e...
Article
Sex determination of unidentified skeletal remains is important and various hard-tissue parameters have been evaluated towards this end. The dentition is considered as a useful adjunct in skeletal sex determination, particularly since teeth are resistant to postmortem destruction and fragmentation. Sex dimorphism in tooth size and the accuracy of o...
Article
Denture marking has been recommended for identifying the edentulous, both in day-to-day recognition when dentures are misplaced as well as in forensic scenarios. The purpose of this study was to test the use of patient photographs as a denture marker and to compare it with conventional marking systems as well as discussing its suitability in the In...
Article
Age assessment may be a crucial step in postmortem profiling leading to confirmative identification. Among the traditional dental parameters used for estimating age, root dentin translucency is considered to be least affected by external stimuli and most suitable for the purpose. Using this variable, Bang and Ramm in 1970 developed an elaborate met...
Article
Measuring teeth is a useful adjunct in sex assessment. Canines, in particular, have the greatest degree of sexual dimorphism, resist disease and survive postmortem trauma, rendering them highly valuable in identification. Hence, their exclusive use in odontometric sex assessment using the Mandibular Canine Index (MCI) has been advocated before. The...
