Amongst the various calcified structures in the human body, teeth have gained lot of popularity in estimating the sex of an individual as they are highly resistant to destruction and decomposition. Using permanent mandibular canines many researchers have predicted a high level of accuracy in identifying the sex correctly. The purpose of our study was to gauge the effectiveness of mandibular canines in discerning sex.
MATERIALS & METHODS: Fifty dental casts each of males and females were utilized for the study. Mesio-distal dimension and inter-canine distance of mandibular right and left canine was recorded using digital vernier caliper and mandibular canine index was calculated.
The mean value of mesio-distal dimensions of right and left mandibular canine was slightly greater in males compared to females. The mandibular canine index was equal in both sexes. Inter-canine distance was marginally higher in males compared to females. Despite of higher values in males none of the parameters were statistically significant.
The results herein bolster contemporary studies that mesio-distal dimensions of mandibular canines and mandibular canine index do not reflect sexual dimorphism and that its application should be discontinued in sex prediction among Indian populations.

在人体各种钙化结构中，牙齿在估计个体性别方面颇受关注，因为它们具有高度的抗破坏和抗分解能力。许多研究人员利用恒下颌尖牙在正确识别性别方面预测了较高的准确率。我们研究的目的是评估下颌尖牙在辨别性别方面的有效性。
本研究使用了50个男性和50个女性的牙模。使用数字游标卡尺记录下颌左右尖牙的近远中尺寸和尖牙间距离，并计算下颌尖牙指数。
男性下颌左右尖牙的近远中尺寸平均值略大于女性。两性的下颌尖牙指数相等。男性的尖牙间距离略高于女性。尽管男性的数值较高，但所有参数均无统计学意义。
本文结果支持当代研究，即下颌尖牙的近远中尺寸和下颌尖牙指数不能反映性别二态性，在印度人群的性别预测中应停止使用。如何引用本文：Hosmani J V, Nayak R S, Kotrashetti V S, Pradeep S, Babji D. 下颌尖牙作为性别二分法指标的可靠性。《国际口腔健康杂志》2013年；5(1):1 - 7。
