This study was carried out to determine the reliability of sex determination from teeth pulp tissue.
This study was carried on 60 maxillary and mandibular premolars and permanent molars (30 male teeth and 30 female teeth) which were indicated for extraction. The teeth were categorized into three groups of 20 each (10 from males and 10 from females).Group 1-pulp tissue from teeth examined immediately after extraction. Group 2- and Group 3-pulp tissue examined from teeth one and five month after extraction, respectively. Teeth was sectioned and pulpal cells were stained with quinacrine dihydrochloride. The cells were observed with fluorescent microscope for fluorescent body. Gender was determined by identification of Y chromosome fluorescence in dental pulp.
Freshly extracted teeth and for those examined one month later, sensitivity, specificity, positive predictive value, negative predictive value, and efficiency were all 100%.
The fluorescent Y body test is shown to be a reliable, simple, and cost-effective technique for gender identification in the immediate postmortem period up to one month.
本研究旨在确定牙髓组织性别鉴定的可靠性。
本研究共纳入 60 颗上颌和下颌前磨牙和恒磨牙（30 颗男性牙齿和 30 颗女性牙齿），这些牙齿均因需要拔除而被纳入研究。这些牙齿被分为三组，每组 20 颗（10 颗来自男性，10 颗来自女性）。第 1 组：拔牙后立即检查牙髓组织。第 2 组和第 3 组：拔牙后 1 个月和 5 个月分别检查牙髓组织。牙齿被切成薄片，用盐酸吖啶橙染色牙髓细胞。在荧光显微镜下观察荧光体，以确定性别。通过鉴定牙髓中的 Y 染色体荧光来确定性别。
新鲜拔出的牙齿和一个月后检查的牙齿，其敏感性、特异性、阳性预测值、阴性预测值和效率均为 100%。
荧光 Y 体试验是一种可靠、简单、经济有效的技术，可用于即时死后至一个月内的性别鉴定。
