The comparative evaluation of tooth morphometrics with facial and body parameters has been attempted in the past. That there exists a possible relation between tooth crown length, especially of the anterior teeth, and the facial and body height, has been consistently proposed. The present study aims to evaluate and statistically analyse the height of the clinical crown of the permanent maxillary central incisor with the facial height and body height of individuals involved in the study. 100 subjects (50M/50F) were included in the study. The tooth crown length was assessed from dental casts using digital vernier calipers, while the facial height and body height were physically evaluated based on established landmarks. The mean height of the maxillary central incisor clinical crown in males was 11.6mm and in females 10.5mm. The mean facial height for males was 17.67cm and that for the females was 17.16cm. The average height of the males in the study group was 180.34cm and for the females 160.61cm. The total facial height was found significantly correlated to the body height using Spearman’s coefficient of variation (r=0.283, p=0.004 at p<0.01). There was no statistical correlation between total crown length and body height. The present study has established conclusive evidence of a statistical correlation between facial height and body height of the individual. Although no definitive correlations could be established between total crown length and body height, the use of the established parameters will be helpful in the fields of forensic odontology and anthropology.
