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(More)
OBJECTIVES The aim of the study was to investigate differences in the shape of the palatal rugae in two populations of India and develop discriminant function to identify the populations based on rugae shape. METHODS Thirty plaster casts from each population group, equally distributed between the sexes and belonging to similar age-group, were examined for(More)
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 evaluating(More)
Sex dimorphism in the Nepalese dentition is described using univariate and discriminant analyses. Canines showed the greatest univariate sex dimorphism, followed by the buccolingual (BL) dimension of maxillary first and second molars. Overall, the maxillary teeth and BL dimensions showed greater univariate sex differences. However, less than half of the(More)
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 teeth on(More)
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 method and(More)
OBJECTIVES 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(More)
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 examines the(More)
Tooth crown dimensions are reasonably accurate predictors of sex and are useful adjuncts in sex assessment. This study explores the utility of buccolingual (BL) and mesiodistal (MD) measurements in sex differentiation when used independently. BL and MD measurements of 28 teeth (third molars excluded) were obtained from a group of 53 Nepalese subjects (22(More)
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) followed(More)
