Teeth are one of the strongest hard tissues that can resist a variety of antemortem and postmortem insults and an important evidence in the field of medicolegal and forensics. In the identification of unknown human remains of the deceased, stature estimation is a preliminary investigation. Previously, the comparison of osteometry with odontometry in stature determination has been made. Similarly, an attempt is made to estimate stature using intercanine and intermolar width which may be a forensic tool in the future.
The aim of this study was to determine stature using intercanine and intermolar width in the maxillary and mandibular arches and correlating to identify highly reliable parameter among the two. Further to evaluate the usefulness of odontometry in stature determination.
Subjects for the study were recruited from the outpatient department of APDCH and students of APDCH. One hundred subjects were included in the study comprising fifty males and fifty females within the age group of 17-28 years as per inclusion criteria. Digital Vernier caliper for measuring intercanine width (cusp tips on either sides) and intermolar width (central fossa of 1 molar on either sides) on the study models and standard anthropometer for measuring the height of the subject (vertex to the floor).
Compared to other parameters, the maxillary intercanine distance is statistically significant to = 0.05 with correlation value of 0.06 by Pearson correlation method.
The data collected were subjected to statistical analysis and was found that out of the four selected odontometric parameters, maxillary intercanine width with a = of 0.032 and Pearson correlation of 0.307 in Group 1 (males) were found to show a significant correlation with height. Regression analysis was done, and regression equations were derived. The following regression equation can be used to calculate the height of an individual, Group 1 (male) -Y = B+ Ax. Y = 135.5 + 0.947X (X - maxillary inter canine width). This method of stature prediction may be of relative importance but not of absolute certainty, thereby making it an adjunct to various other methods of stature prediction. Therefore, using odontometric parameters in combination improves the predictability of estimating stature rather than a single parameter.
牙齿是最坚硬的组织之一,能够抵抗各种生前和死后的损伤,是法医学和法医领域的重要证据。在识别死者的未知遗骸时,身高估计是一项初步调查。此前,已经在身高测定中对骨测量法和牙测量法进行了比较。同样,人们也尝试使用犬齿间宽度和磨牙间宽度来估计身高,这在未来可能会成为一种法医工具。
本研究的目的是利用上颌和下颌牙弓中的犬齿间宽度和磨牙间宽度来确定身高,并进行相关性分析以找出两者中高度可靠的参数。此外,评估牙测量法在身高测定中的实用性。
本研究的受试者从阿萨姆邦医学科学与研究机构(APDCH)门诊部和APDCH的学生中招募。根据纳入标准,研究共纳入100名受试者,包括50名男性和50名女性,年龄在17至28岁之间。使用数字游标卡尺在研究模型上测量犬齿间宽度(两侧牙尖)和磨牙间宽度(两侧第一磨牙中央窝),并使用标准人体测量仪测量受试者的身高(头顶至地面)。
与其他参数相比,通过Pearson相关法,上颌犬齿间距离在统计学上具有显著意义(P = 0.05),相关值为0.06。
对收集到的数据进行统计分析后发现,在所选的四个牙测量参数中,第一组(男性)中上颌犬齿间宽度的P值为0.032,Pearson相关性为0.307,与身高显示出显著相关性。进行了回归分析并得出了回归方程。以下回归方程可用于计算个体的身高,第一组(男性)-Y = B + Ax。Y = 135.5 + 0.947X(X - 上颌犬齿间宽度)。这种身高预测方法可能具有相对重要性,但并非绝对确定,因此它是各种其他身高预测方法的辅助手段。因此,结合使用牙测量参数可提高身高估计的可预测性,而不是单一参数。
