目的 利用三维数字化测量方法对上下颌牙弓宽度进行测量,来评估上下颌牙弓宽度与性别的相关性。方法 本研究收集120名成年人的上下颌三维数字模型,男女各60名,利用逆向工程软件,分别测量上下颌两尖牙间、两第一前磨牙间、两第二前磨牙间、两第一磨牙间和两第二磨牙间的宽度,并对其进行统计分析,建立判别函数,以评估上下颌各牙弓的宽度与性别的关系。通过ROC曲线分析,得出所有牙弓尺寸估计性别的可能性。用Garn等给出的方法计算性别二型性百分比。结果 除了两下颌尖牙间宽度,其余上下颌各牙弓宽度的平均值男性均大于女性,且具有统计学差异(p <0.05),用其建立判别函数,鉴定准确率为59.2%~80%。其中,上颌两第二磨牙间的宽度对性别的判断效果最好,为80%。性别鉴定的准确率随着从尖牙到第二磨牙的远移而增加。ROC曲线分析表明上颌两第二磨牙间宽度最有可能估计性别,曲线下面积为0.887。上颌第二磨牙间宽度的性别二型性最高,达到91.8%。结论 上下颌各牙弓间的宽度在不同的性别之间存在差异,尤其是上颌第二磨牙间的宽度,因此可考虑将其用于遗骸的性别鉴定。  相似文献

The authors compared arch width measurements of diagnostic dental models obtained from dental school patients. Arch width measurements were taken in the canine area on each dental cast in an effort to assist forensic dental investigators in matching certain classes of subjects to the bites they might possibly inflict. If any canine teeth were absent, the measurements were taken using other specified adjacent teeth which the investigators felt would be interpreted as the arch width determiners in a bite mark injury. The ages of the subjects varied from 14 to 87 years. Statistical comparison of the maxillary arch width, mandibular arch width, and the mean difference between maxillary and mandibular arch width were performed. Significant differences between the arch width measurements were found to exist between several classes of subjects based on race and sex.  相似文献

The morphology of dental arch has been studied in representatives of 11 contrast (by anthropological characteristics) ethnic groups from regions of their compact residence. The sampling from each ethnic group consisted of 200 subjects (100 male and 100 female) aged 13-20 years. A total of 4,500 plaster models of dental arches were examined. The results were statistically processed using factor, canonical, discriminant analyses, and multidimensional scanning. The data on the variability and sex dimorphism in the size and shape of dental arches in subjects belonging to different ethnic groups may be practically significant in forensic medical personality identification.  相似文献

Bite mark analysis in forensic dentistry presupposes that the human dentition is unique and that its characteristics can be transferred precisely to several materials. The aim of the present study was to register the frequency of missing anterior teeth in the Brazilian adult population, discussing its potential importance in bite mark analysis. Data from the Brazilian Oral Health Survey were used; 13,431 male and female individuals aged 35 to 44 were examined according to the criteria of the World Health Organization. The analysis of Poisson regression was performed in order to calculate the rating ratios and the respective confidence interval at 95%. A total of 13,431 adults participated in the study. Among male individuals, 2063 (47.00%) were dentate and 2036 (46.40%) had at least one missing tooth. Only 254 (5.83%) were totally edentulous. A significant number of males and females presented 6 missing teeth in the same dental arch, revealing the poor state of oral health of adult Brazilians. Missing teeth were more frequent in the upper dental arch than in the lower arch. In the upper dental arch, the incisor group (central and lateral) was missing the most. In the lower dental arch, however, a certain lack of homogeneity was observed among the different dental groups as regards missing teeth. White individuals presented a smaller proportion of missing teeth compared to the other ethnic groups. Females were 1.61 (CI 1.50–1.73) times more likely than males to present missing teeth. The absence of upper teeth and the presence of lower teeth were observed in 16.10% of the individuals. Further research should also include an analysis of different age groups. This would increase the potential of applying this kind of information to bite mark analysis.  相似文献

Seventeen measuring parameters were used to characterize 197 mandibles (109 males, 88 females) taken from the corpses of people 20-80 years of age from the Rhine-Main-Neckar area. The representative measuring parameters and discriminating functions of intact lower jaws and lower jaw fragments of most frequent fracture types were determined in this practice group by means of discriminating analysis. In the present research material it was possible to determine sex accurately from an intact lower jaw bone in 82.6% (m) and 79.5% (f) of the cases. Furthermore, our results show clearly that sex may even be determined from lower jaw fragments. The classification was correct, depending on the type of fragment, in 72.5%-81.7% (m) and 71.6%-79.5% (f) of the cases.  相似文献

Abstract: The aim of this study was to establish a prediction formula to allow for the determination of sex among the southeastern French population using dental measurements. The sample consisted of 105 individuals (57 males and 48 females, aged between 18 and 25 years). Dental measurements were calculated using Euclidean distances, in three‐dimensional space, from point coordinates obtained by a Microscribe. A multiple logistic regression analysis was performed to establish the prediction formula. Among 12 selected dental distances, a stepwise logistic regression analysis highlighted the two most significant discriminate predictors of sex: one located at the mandible and the other at the maxilla. A cutpoint was proposed to prediction of true sex. The prediction formula was then tested on a validation sample (20 males and 34 females, aged between 18 and 62 years and with a history of orthodontics or restorative care) to evaluate the accuracy of the method.  相似文献

Although the assignment of sex to immature skeletal remains is considered problematic, some traits have been considered useful for both forensic and bioarchaeological applications. One such trait is the arch criterion found in subadult ilia, which is defined relative to the greater sciatic notch-auricular surface area. In adults, the composite arch has also been described in relation to this area and has proven relatively successful in sex determination. This study offers an examination of the accuracy of the arch criterion and the composite arch in determining the sex of subadult skeletal remains, and an assessment of intra- and inter-observer scoring error. A sample of 97 skeletons of known sex and age (<15 years) from the Lisbon collection (Portugal) were selected and the traits were scored by three observers on orthogonal photos of each ilium. In general the agreement within (67.7–88.5%) and between (50.5–76.3%) examiners was poor and overall accuracy (26.7–52.6%) did not meet the expectations of that reported in previous studies. The authors suggest that this derives from great variation in morphology, difficulties in interpreting criteria and possibly a lack of association between the expression of the traits and sex. Careful examination of sex-related morphology in the immature skeleton and additional blind tests of so-called useful traits should continue to be carried out.  相似文献

Forensically identifying a suspect's dentition from a bitemark in an open population requires the supposition that every person's dental alignment is different. There have been few studies that have tested this claim. Four hundred and ten lower anterior dentitions from a selected population and 110 lower anterior dentitions from one that was orthodontically treated were measured using geometric morphometric analysis, allowing comparison of arch shape. Dental match rates of 1.46% and 42.7% of individuals were found in the respective populations, given an established measurement error. Orthodontic treatment had a strong effect on match rate suggesting that treated or naturally well-aligned dentitions may be indistinguishable. Sexual dimorphism was found to be only slightly significant. Principal shape variation in both populations was degree of arch curvature. Results of studying these populations show that dental matches can occur, and that statements of certainty concerning individualization in such populations should be approached with caution.  相似文献
