“…[1] Dental anthropology is concerned with the study of morphological variation (dental morphological features) and metrics of the dentition of human populations over time (prehistoric and modern) and space (ethnic influences) and their relation with the processes of adaptation and dietary changes that led to the evolution of the dental system and the human race. [2] For forensic and archeological excavations, every time it is not possible to get all the bones of an individual and hence the collected skull and teeth will provide an identification.…”

Background: Sexual dimorphism refers to those differences in size, stature and appearance between male and female that can be applied to dental identification of humans. Teeth are good sources of material for civil and medico-legal identification. Tooth size standards based on odontometric investigation can be used in age and sex determination. The present study was planned to evaluate the existence of sexual dimorphism using both buccolingual (BL) and mesiodistal (MD) dimensions and prevalence of cusp of Carabelli in maxillary permanent first molars in Gujarati population. Materials and Methods: Totally 60 students (30 males and 30 females) of Gujarati population with 10-35 years of age were selected by random sampling method. After oral examination, impressions of the maxillary arch were taken and the BL and MD dimensions of the maxillary first molars were measured using digital Vernier calipers on study casts and also checked for presence of cusp of Carebelli. Results:The mean values of parameters (BL and MD dimensions) were greater in male when compared to female. There was a significant difference in mean values of MD dimensions of maxillary right first molar of males (10.39 ± 0.48) and females (10.11 ± 0.52) (P = 0.03). Moreover, presence of cusp of Carabelli was found to be more frequent in males (23.33%) when compared to females (11.67%). Conclusion:The study results revealed that MD dimension can be used as a parameter to check the sexual dimorphism in Gujarati population.

“…Recent studies have shown that the most dimorphic tooth is the mandibular canine and it can be of immense medicolegal use in identification [3, 5, 8]. The measure of the coronal tissue proportions of permanent mandibular canines suggests that males have heavier teeth and more dentin than their female counterparts [1].…”

Background and Objective. In forensic investigations, mandibular canines provide excellent materials to identify gender since they are more likely to survive disasters. The objective of this study was to investigate gender dimorphism by comparing the mesiodistal width of mandibular permanent canines and intercanine distance in a group of Lebanese population. Methods. Participants consisted of undergraduate students from the School of Dentistry, Lebanese University, for two academic years who fulfilled the inclusion criteria. Canine widths and intercanine distance were measured by one operator directly on dental casts using a digital caliper. Results. One hundred thirty-three Lebanese dental students (54 males and 69 females) aged 18–25 were included in the study. The intercanine distance was significantly greater in males (P value < 0.0001). The right and the left canine widths were significantly greater in males than in females (P value < 0.0001). However, no significant difference was found between left and right canines for males (P value > 0.05) and females (P value > 0.05). The mean width of canine was greater than 7.188 mm for males. Conclusion. The parameters measured in the present study are of great help in sex identification in forensic investigations in the Lebanese adult population.

“…Many researches were done to identify the genders using the maxillary and mandibular canines. They depended on the mesio-distal dimension of these teeth (5,6) and in many articles on the intercanine width in addition to the mesio-distal width to get the canine index and standard canine index (2,(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) . Other researches studied the bucco-lingual dimension of teeth (18,19) , height of tooth (3) and permanent maxillary first molar (20) as a base for gender identification.…”

Background: This study aimed to determine the gender of a sample of Iraqi adults utilizing the mesio-distal width of maxillary central incisors and canines and to determine the percentage of dimorphism as an aid in forensic dentistry. Materials and methods: The sample included 230 subjects (115 males and 115 females) with an age ranged between 17-25 years and Class I dental and skeletal relations. Study casts were taken for each subject and the mesio-distal crown dimension was measured manually from the contact points for the maxillary central incisors and canines (both sides) using digital vernier caliper gauge. Descriptive statistics were obtained for the measurements for both genders; independent samples t-test was performed to evaluate the gender difference, percentage of dimorphism and stepwise discriminant function statistics were performed to determine the teeth that can be used for gender identification in addition to the percentage of gender identification accuracy. Results and Conclusions: Generally, the mesio-distal dimensions of the maxillary central incisor and canine were larger in males than females with a high significant difference (P ≤ 0.001). Stepwise discriminant function statistics indicated that the right central incisor and canine were the most predominant teeth in gender identification and the accuracy of identification reached up to 69.6%.
