【摘要】: 目的:本课题旨在探讨牙齿的多种增龄性变化与年龄之间的关系,寻求一种简便且准确的推断牙龄的方法,而为特异型尸体司法鉴定时根据牙齿判断年龄提供证据,也为人类学研究积累资料。 方法:从山西医科大学法医学院及口腔医院收集的636磨牙(无龋坏、无根尖病变)分为Max1、Max2、Man1、Man2四组,根据牙齿的增龄变化特点,筛选了5个与牙龄变化密切相关的指标(牙齿的磨耗、接触区面积、牙本质髓室指数、根尖牙骨质的厚度、根尖牙本质透明),提出了指标的分级标准和评分标准,对各组的牙齿测量后进行数据处理和统计分析。 结果:牙齿的磨耗、接触区面积、牙本质髓室指数、根尖牙骨质的厚度、根尖牙本质透明均反映出与年龄高度相关关系,用这5个指标与年龄所建立的判别年龄的多元回归方程经统计学分析,回归高度显著。将全部样本进行计算机方程回代检验,达到了设计与统计学要求。 山祖穿医斗斗大学 祠眨士学位论文 结论:本研究证实了该5项指标与年龄的高度相关关系, 获得了一个判别年龄的多元回归方程,为司法鉴定提供了客 观的依据。
[Abstract]:Objective: the purpose of this study was to explore the relationship between tooth aging and age, to find a simple and accurate method to estimate tooth age, and to provide evidence for judging tooth age according to tooth age in special shaped cadavers. It also accumulates data for anthropological research. Methods: 636 molars (no caries, no apical lesion) were collected from the College of Forensic Medicine of Shanxi Medical University and Stomatological Hospital. Five indexes closely related to tooth age (tooth wear, contact area, pulp chamber index, bone thickness of canine teeth, apical dentine hyaline) were selected, and the grading criteria and scoring criteria were proposed. Data processing and statistical analysis were carried out after tooth measurement in each group. Results: tooth attrition, area of contact area, pulp chamber index of dentin, thickness of root canine bone, apical dentin transparency were all correlated with age. The multivariate regression equation established by these five indexes and age was statistically analyzed and the regression height was significant. All the samples were tested by computer equation and met the requirements of design and statistics. Shanzu Dou University. Temple Blint thesis. Conclusion: this study confirmed the high correlation between the five indexes and age. A multivariate regression equation for judging age is obtained, which provides a guest for forensic expertise. The basis of the view.
