Background: Linear odontometry is customarily used in gender determination which can pose difficulties in cases of tooth decay, attrition since they mainly involve the proximal surfaces. Objectives: The present cross-sectional observation study, estimated the efficacy of alternative measurements, that is, diagonal measurements and cervical measurements in gender determination in comparison to routine odontometry. Material and Methods: A total of 200 dental cast models (upper and lower) of 100 individuals (50 male and 50 female) from Maharashtra state were included. Results: Univariate discriminant function analysis showed that, in maxillary molars, MD width gave the highest gender dimorphism of 64%, followed by BL with 62%. In the mandibular teeth, MD gave an accuracy of 75% followed by MB-DL with 73%. Multivariate logistic regression analysis showed that overall diagonal and linear measurements gave the highest dimorphism of 81% with 80% correctly identified as females and 82% as males. The mandibular MD, BL and MB-DL gave an accuracy of 79% with 78% corrected identified as females and 80% correctly identified as males. Mandibular ML-DB and Cervical DB-CML together gave an accuracy of 77% and mandibular MD with75%. Conclusion: Thus, the study proves that diagonal measurements give almost equivalent or better results than linear measurements in gender determination.

“…Although many bones such as the pelvis and skull give the most reliable results of sexual dimorphism by morphological and metric analysis, rarely, the only evidence available for gender determination maybe teeth. [ 7 ] They are one of the strongest human tissues and are known to resist a variety of antemortem and postmortem insults. Sex determination is one of the prime factors employed to assist with the identification of an individual.…”

Introduction: Sex identification of skeletal remains is one of the prime factors employed in identification of an individual. Teeth, the most hard and stable human tissue, which is resistant to physical insults, serve as a valuable material for forensic, anthropological, odontologic and genetics. Among the four main attributes of biological identity, gender determination is usually the first step in the human identification process. Hence, the main objective of the present study was to assess the dimorphic status of mesiodistal (MD) width, labiolingual (LL) width as well as cervicoincisal (CI) length of the crown in both maxillary and mandibular permanent incisors, canines and first molars. Materials and Methods: The present study comprised a set of 100 casts (50 males and 50 females) between the age group of 20–50 years of age. Impressions were made using alginate impression and study models were prepared using dental stone. The CI length of the crown, maximum MD width and maximum LL width of both maxillary and mandibular permanent incisors, canines and first molars were evaluated using digital Vernier calipers. The obtained data were analyzed using linear discriminant analysis and logistic regression method. Results: This study concludes that MD dimension of maxillary canine and CI dimension of mandibular first molar as reliable indicators for gender determination than mandibular canine, maxillary and mandibular central incisors and maxillary first molar dimensions. Conclusion: This study concludes that MD dimension of maxillary canine and CI dimension of mandibular first molar as reliable indicators for gender determination than mandibular canine, maxillary and mandibular central incisors and maxillary first molar dimensions.

“…However, because sexual dimorphism varies by population, sex differentiation from odontometric data necessitates population-specific norms [3]. Various research conducted worldwide demonstrates the usefulness of odontometric in gender determination [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

There is a disparity between males and females when it comes to size and appearance. In forensic and anthropological investigations, it is crucial to identify an unknown individual's gender, and it is possible to discern individual differences based on differences in dental features among populations. For identifying individuals, tooth dimensions are an effective, simple, and low-cost means of determining sex. Based on dental casts, this study aims to assess sexual dimorphism among four ethnic tribes of Northeast India using the mesiodistal (MD) dimension of canines and arch perimeter (AP) of the upper and lower jaws. MethodsIn each of the four ethnic groups studied, 50 males and 50 females with dental casts were measured in millimetres for the MD dimension of canines and AP of the upper and lower jaws. SPSS version 20 (IBM Corp., Armonk, NY) was used to analyze the data based on Student's t-test, considering a p-value of <0.05 as significant. ResultsMales had significantly larger MD dimensions of canines in the maxillary and mandibular jaws (p-value<0.05). The AP of both maxilla and mandible are higher in males than females in all four ethnic groups. However, the difference between the two genders for the AP of the maxilla is statistically significant only in Meitei and Singpho groups (p-value<0.05). In the case of the mandibular jaw, the AP was significantly lower in females in all four ethnic groups (p-value<0.05). ConclusionSignificant sexual dimorphism exists among the individuals in the four ethnic group populations. The MD dimension and AP are essential to establish sexual dimorphism among populations. The MD dimension of the maxillary and mandibular canine and AP showed significant sexual dimorphism in the present study among all four ethnic groups.

Evaluation of sexual dimorphism using permanent maxillary first molar in Sri Ganganagar population

Abstract: Left maxillary permanent first molar showed minimum mean difference of measurements on study cast and introrally than right, thus better predictor for gender dimorphism in forensics.
