Abstract

Background: Sex determination is an important aspect in the identification of individuals especially in cases of identifying victims of mass disasters, organised crimes etc. Odontometry is the measurement and study of tooth size. Cranial anthropometry is the measurement of skull dimensions and is considered to be a versatile technique in the investigation of the craniofacial skeleton because of its validity and practicality.
Aim: To assess tooth crown area of the deciduous molar teeth, to assess head size, to evaluate the extent of sexual dimorphism using head and dental dimension
Methodology: This study was done in 150 boys and 150 girls. Maxillary and mandibular arch impressions were made, casts were made with dental stone. A vernier calliper was used for obtaining the measurements. Mesiodistal width and buccolingual width of all the molars were measured in millimetres, tooth crown area (TCA) was calculated. Head dimensions were measured using Martin spreading calliper, Cephalic Index (CI) was calculated. Statistical analysis was done using unpaired “t” test, and logistic regression analysis was performed.
Results: The highest tooth crown area was shown by mandibular left second deciduous molar for both boys and girls (p<0> Tooth crown area and head size can serve as a valuable aid for sex determination in pediatric population.
 

Keywords: Forensic anthropometry, Sexual dimorphism, Tooth crown area, Cephalic index.
