- 牙齿是人类学、遗传学、牙科学和法医学研究的极好材料。在所有牙齿中，下颌犬齿被发现表现出最大的性二型性。为了确定北印度人下颌尖牙的形态测量标准，本研究对60名17-21岁年龄组的受试者（男：女：：30：30）进行了研究。在口内及铸型上测量下颌尖牙的牙间距和宽度，计算下颌尖牙指数。结果表明，无论是口内测量还是石膏测量，下颌尖牙都存在明显的性别差异。在两个犬科动物中，左犬科动物比右犬科动物表现出更大的两性异形。当犬齿宽度> 7 mm时，性别为雄性的概率为100%。如果小于7 mm，则性别可能是任何一种。
— Teeth form an excellent material for anthropological, genetic, odontologic and forensic investigations. Amongst all the teeth, the mandibular canines are found to exhibit greatest sexual dimorphism. To define the morphometric criteria for mandibular canines in North Indian population, the present study has been conducted in 60 subjects (M:F::30:30) in the age group of 17-21 years. Intercanine distance & width of both right with left mandibular canines were measured intra orally as well as on the casts of same subjects & the mandibular canine index was calculated. It was seen that a definite statistically significant sexual dimorphism exists in the mandibular canines whether measurements are taken intraorally or on casts. Out of the two canines, the left one exhibits greater sexual dimorphism as compared with the right one. It is also concluded that whenever the width of either canine is >7mm the probability of sex being male is 100%. While if it is <7mm, the sex could be either.
