Abstract

INTRODUCTION

One of the important pieces of information gathered from tooth analysis is the sex of an individual. In most human living populations, mandibular canines show the greatest dimorphism and greatest dimensional differences between males and females. In view of these facts, the aim of this study was to establish the standard mandibular canine index (MCI) and estimate the sexual dimorphism in the population of Gandhinagar district of Gujarat state.

MATERIALS AND METHODS

The study consisted of 400 subjects, 200 males and 200 females in the age group of 20-40 years. The mesiodistal (MD) width of the right and left canine and the intercanine distance were measured. These values were used to derive the MCI and establish the amount of sexual dimorphism exhibited by the mandibular canine.

RESULTS

The MD crown width of the permanent mandibular right and left canines as well as mandibular intercanine distance of the males was found to be larger in size than in the females. The right mandibular canine exhibited 8.42% of sexual dimorphism while the left mandibular canine exhibited 8.40% of sexual dimorphism. The intercanine distance showed 2.75% of sexual dimorphism. The value of standard MCI derived using the formula devised by Rao . was 0.254 mm for the population residing in the Gandhinagar district.

CONCLUSION

The present study supports the usefulness of the MCI in gender determination. The method of using mandibular canine indices is advantageous as it is easy, rapid, and cost-effective, requires no elaborate apparatus, and is suited for situations where large a number of samples have to be analyzed.

摘要

引言

从牙齿分析中收集到的重要信息之一是个体的性别。在大多数人类居住群体中，下颌尖牙在男性和女性之间表现出最大的二态性和最大的尺寸差异。鉴于这些事实，本研究的目的是建立标准下颌尖牙指数（MCI），并估计古吉拉特邦甘地讷格尔地区人群中的性别二态性。

材料与方法

该研究包括400名年龄在20至40岁之间的受试者，其中男性200名，女性200名。测量了左右尖牙的近远中（MD）宽度以及尖牙间距离。这些值用于推导MCI并确定下颌尖牙所表现出的性别二态性程度。

结果

发现男性的恒牙下颌左右尖牙的MD冠宽以及下颌尖牙间距离比女性的更大。右下颌尖牙表现出8.42%的性别二态性，而左下颌尖牙表现出8.40%的性别二态性。尖牙间距离表现出2.75%的性别二态性。使用Rao设计的公式得出的甘地讷格尔地区人群的标准MCI值为0.254毫米。

结论

本研究支持MCI在性别判定中的有用性。使用下颌尖牙指数的方法具有优势，因为它简单易行、快速且经济高效，不需要精密仪器，并且适用于需要分析大量样本的情况。
