Introduction: Identification by means of dental tissue is an easy and helpful tool in forensic Odontology. Dental architecture grows in proportion to the human body and shows some positive correlation. Being hard and resistant to adverse conditions makes it very valuable in scientific studies. Since canine has a longer root in the jaw, it makes it a notifiable structure that can be used in research. Hence, among the dental tissues, canine tooth is chosen most often in studies. Materials and methods: study was conducted in Department of Forensic Medicine & Toxicology, Himalayan Institute of Medical Sciences, Dehradun, Uttarakhand, involving 200 subjects (100 males & 100 females) 19 to 24 years of age. Intercanine width of their maxilla and mandible were measured by manual vernier caliper to determine sex and height; data was analyzed by SPSS software. Result: Mean Maxillary and Mandibular Intercanine width of males was found to be more as compared to females and were statistically highly significant. Sexual dimorphism was more by using Mandibular Intercanine width as compared to Maxillary Intercanine width. Percentage accuracy of sex determination was found to be more in Maxillary Intercanine width. Simple linear regression equations were obtained for predicting height from Intercanine width. Correlation between Height and Intercanine width of Maxilla and Mandible was statistically significant in males than females. Conclusion: Sexual dimorphism and stature estimation is possible by measuring Intercanine width. However, better prediction with more accurate height and sex determination requires a combined study of dental tissue along with bones.
