“…The observation on the relative dimensions of the buccolingual and mesiodistal widths was in tandem with previous studies [91213141920]. It was also consistent with Sharma et al [11] in the case of maxillary SM; but on the contrary, it was at variance with the latter in the case of maxillary FM. The reason for this may be because the MD is limited by teeth at both the mesial and distal contact points in contrast to the BL that does not have dental structures limiting it.…”

The spate of unidentified human remains as a result of kidnapping, killings, and so forth was the reason for this study. The purpose of this study was to measure the crown and cusps of each of the permanent maxillary first two molars to determine discriminant score and functions among Urhobo people of Nigeria. All Undergraduates of the Delta State University, Abraka, who are pure breeds Urhobo, form the study population. Three hundred and six subjects (171 males and 135 females), with mean age 22.88±3.34 years, participated in the study, which is based on the simple random sampling technique. All four crown widths and the four cusps of the maxillary first two molars were measured in millimeter, from a prepared study models of dental stone, and crown area, crown and cusps indices were calculated. The level of sexual dimorphism was also calculated for each parameter. Descriptive statistics was used to summarize the data while inferential statistics were used to ascertain significant sexual differences and to determine discriminant scores and functions. Statistical significance was fixed at P≤0.05. Crown and cusp dimensions of the first two permanent maxillary molars exhibited statistically significant sexual dimorphism. The highest percentage of sexual dimorphism was crown area of maxillary second molar (9.08%), followed by first molar (7.85%). Next, were metacone, paracone, disto-buccomesio-lingual, and mesio-buccodisto-lingual widths. The overall sex discriminatory precisions of the various parameters in the maxillary first two molars are good. The findings of this study are of relevance in forensic anthropology.

Aims and Objectives:Sexual dimorphism refers to the variations in tooth size and shape between the sexes. The consistency of these variations is valuable in the identification of the sex of an individual in times of mass disaster when whole body parts get destroyed or are unavailable. There exist differences in the expression of these variables across races and regions. This study aims to tabulate and identify the variations in tooth measurements using standarized reference points in an attempt to establish parameters of sexual dimorphism.Materials and Methods:100 individuals (50 of each sex) in the age group 19-23 years were assessed for standard morphometric parameters of the maxillary central incisor, canine, premolar and molar. Odontometric measurements of established parameters were recorded from impression casts of the maxillary jaws. The mesiodistal width (MDW), the bucco-ligual width (BLW), the crown length (CL) and the cervical angle (CA) were charted among the teeth. The consistency of the variations was statistically analyzed and a logistic regression table was prepared to identify the sex of the individual from the tooth measurements.Results and Conclusions:The BLW, MDW and CL reflected significant variations among all the teeth to be effective in establishing sexual dimorphism. CA as a parameter was inadequate across all the teeth. The permanent maxillary canine was the most important tooth to be reflective of the gender and statistically significant to be utilized for gender determination.

“…Furthermore, cuspal dimensions aid in diagonal measurements due to its different evolutionary background and growth pattern. [8] According to Hillson, most of the times teeth were attrited limiting the usefulness of tooth crown diameter measurements as they are usually defined at the widest points of the crown. [3] Univariate analysis of previous studies showed that the mesiodistal dimensions of male teeth were greater than female dentitions for all individual type of tooth in both maxillary and mandibular arches (Richardson et al).…”

Background: Measurements of diagonal distances of teeth were one of the major tools in assessment of sexual dimorphism in various populations. Various research and studies were aimed at achieving the perfect results in forensic context. Aims: The study was aimed to assess the degree of sexual dimorphism in permanent mandibular molar of Iranians using diagonal diameters. Objectives: To evaluate the applicability of diagonal measurements in sex determination. Materials and Methods:The study sample consisted of 30 Iranians students of age group between 15 to 25 years that included 15 male samples and 15 female samples ie of 1: 1 ratio. Diagonal distances on the occlusal surfaces and diagonal dimensions on the facial surface were considered. Calculations were done using manual Vernier calliper recorded dimensions were larger in males than in females. Results:The mean values and standard deviation of all recorded dimensions were larger in males than in females. Conclusion of Study:The results showed that occlusal and facial diagonal diameters of molars can be used for sex determination as they present a high degree of sexual dimorphism.
