Dental Anthropology is the study of teeth in a perspective beyond clinical science. That perspective includes the study of dental growth, theories on dental origin, primate dentition and population variation, Tooth size has been studied in subjects to study the influence of sex and to assess the variation in magnitude of sexual dimorphism and patterning of sexual dimorphism in permanent tooth size in various populations. The size of the teeth is of great importance not only to indicate the different activities related to the occlusion or determine the frequency of dento-tooth anomalies applied to the orthodontic treatment, but also to establish sexual dimorphism. Aim: To assess normal data of crown dimension(cervico-incisal, mesio-distal andlabio-lingual/bucco-lingual dimension) in Ghaziabad population. Methodology: This study was done on patients visiting the outpatient department of Shree Bankey Bihari Dental College and Hospital, Masuri, Ghaziabad, also from various colleges and camps. Total number of sample included in present study was study models of 90 people (45 males and 45 females) with Age group of 18 – 30 years. All the study models in which anomalies were found were recorded separately. Result: Total number of study models included in present study was 90. Measurement was done on study models made of Dental stone by means of Digital Vernier calipers Results were discussed in view of scientific knowledge and following conclusions are drawn:- 1. Cast availability is easy. 2. The size of the teeth is of great importance to establish sexual dimorphism. 3. Standard Odontometric data for one population should not be used for other population for the purpose of Forensic Dentistry and Dental Anthropology 4. Microdontia were the common anomalies and the least common was taurodontism. Conclusion: Our study provides normative morphologic data and establishes the existence of statistically significant gender dimorphism among Ghaziabad population, but it is recommended to conduct similar studies on various populations for further confirmation
