Introduction: For the assessment of sexual dimorphism of human skeleton, pelvis has been used with great accuracy by anthropologists and forensic experts. Sacrum, being an integral part of pelvis, has therefore gained importance. Among the various parameters of sacrum, sacral index is the most reliable one, calculated by the formula: Sacral index=max breadth x100/max length of sacrum. This study aimed to determine the significance of sacral index in estimation of sex in north Indian population. Materials and methods: For the present study, 35 dry human sacrum bones were obtained from the Department of Anatomy, KGMU, Lucknow, out of which 32, free of deformity, were used in study. The bones were first separated as male and female on the basis of their gross features. Maximum length and breadth of sacra were measured using digital sliding Vernier calliper and sacral index was calculated. Results: Mean sacral index was significantly higher in females (109.52) as compared to males (92.37). Sex determination done on the basis of gross features were comparable to that done by calculation of sacral index, except in sacrum no. 5,13,14,15 &16. Sacrum no. 5,13,14 &15 were more curved forwards (female feature) while their sacral indices were much lesser (male feature). Sacrum no. 16 had a uniform curvature (male feature) while its sacral index was>105 (female feature). Sacrum no. 16 also had only 3 dorsal and ventral foramina, which was a variation. Conclusions: Sacral index is a reliable criterion for sex determination, useful for anatomical, medicolegal and anthropological purposes.

Dental Evidence

Dental evidence has been demonstrated as a major forensic tool for the identification of individuals and sex determination. The objective of the research was to determine sex in Delta Ibo ethnic group of Nigeria using the mandibular and maxillary canine teeth. Materials and methods. The study comprised 201 (100 males and 101 females) subjects of Delta Ibo ethnicity at the age of 17 – 25 years. The mesiodistal crown width and intercanine distance of both the maxillary and mandibular canines were measured intraorally using a pair of dividers and a ruler. Unpaired T-test at a probability value of p<0.05 was used to ascertain the mean significant differences between the male and female canine indices.   Results. Study results showed a statistically significant difference between male and female mandibular and maxillary canine mesiodistal width. This implied a sexual and reversed sexual dimorphism in the studied population.        Conclusions. The study confirmed that the canines of Delta Ibos exhibit sexual dimorphism like other populations and the maxillary canine indices give the most accurate prediction in sex determination.

Background: In forensic science, skeletal examination is often done with primary focus on identification. Complete identification is a rare event in this type of examination. However, anthropological identification can be done in skeletal examination. Skull is the second best for determination of sex next to pelvis. Maxillary sinuses are paranasal sinuses, and a feature for sexual dimorphism which remains intact in partially charred. The study of maxillary sinus is best done on Computed Tomography.Objectives: The primary objective of this study is to evaluate bilateral maxillary sinus for sexual dimorphism using Computed Tomography.Methodology: A total of 104 CT head cases were studied of which 52 were male and 52 female. The anterior posterior length, transverse width and height of bilateral maxillary sinus were measured in male and female through their DICOM images using inbuilt electronic calliper. Descriptive analysis for mean, paired t test to compare right and left maxillary sinus in both male and female, and student t test for compare male and female were used for analysing the value measured and calculated.Results: Male maxillary sinus (Right 12.76±4.62 & Left 12.39±3.81) was found be to larger than that of female (Right 12.16±4.78 & Left 11.80±4.49). Right and left maxillary sinus of both the sexes showed no significant difference when paired t test was used. Using independent t-test showed no sexual dimorphism between the two sexes.Conclusion: Maxillary sinus is not good tool for sex determination in Nepalese population. However further studies could be done on larger population sample, as smaller sample size could be the limitation of this study.

Background: Sexing of human skeleton is highly contested subject and is usually done by using morphological and metrical traits of big intact bones like skull, mandible, pelvis and long bones etc.1 The stapes remains well protected by being housed in the middle ear, even in the mutilated bodies.Methods: The morphometric study of the 120 human stapes bones from 60 unidentified cadavers was aimed to know the presence of sexual dimorphism.Results: The weight and measurements of footplate could be a good criterion for determining percentage accuracy as male and female respectively and could be used as a potential tool for determination of sex.Conclusions: The study of normal dimensions and indices of stapes will provide insight to the forensic experts for deciding the sex of an individual in the disputed cases. Our findings are the results for guidance and future manipulation in the forensic and legal medicine.

Knowledge of sex of a person becomes the first priority of a forensic investigator in the process of identification. Dental evidence pours in an invaluable informative data towards achieving the final positive results in establishing the unknown’s identity. Studies have shown that the mandibular canine resist disease, survive extreme post-mortem environmental conditions and presents the highest sexual dimorphism amongst all teeth, making them an ideal teeth in forensic identification procedures. The aim of present study was to know the use of the Mandibular Canine Index (MCI) in assessing sex in North Indian population. In a sample size of 80 males and females (40 male and 40 female) in the age group 21-24years, mandibular canine width and Inter canine distance measurements were noted intraorally and the MCI was calculated and compared with stranded MCI values.
