RESUMEN
Introduction: Nasal parameters are important for estimation of stature, gender identification and age estimation. Commonly used Nasal parameters are Nasal height, Nasal breadth and Nasal width; Nasal height is one of the most reliable of which. Previous studies have reported racial differences and geographical variation in Nasal height along with importance in gender differentiation. This study was conducted with aim to measure Nasal heights of Bhavangar city population and check for Nasal height differences among males and females. Subjects and Methods: 510 subjects (243 male and 267 female) were enrolled in the present cross-sectional study, conducted at Government Medical College, Bhavanagar in 2011 after institutional ethical committee approval. Age group of the subjects enrolled in the study was 18 to 30 years. Nasal height was measured with the help of sliding caliper after informed and written consent of the subject. The data was compiled and analyzed with standard statistical methods by Microsoft excel and Epiinfo 7.0TM software. Results: Difference in mean nasal height of Males (46.241 ± 3.518 mm) and females (43.799 ± 3.419) was statistically significant at 95% confidence interval (p value = 0.0001). Conclusion: Nasal height can be used as one of the parameters for gender determination of the subject.
RESUMEN
Context: Gender determination is considered an important step in reconstructing the biological profile of unknown individuals from the forensic context. Assessment of sex differences from human remains will be of immense help as it would narrow down fields of search to 50 %. Aims: To evaluate the accuracy of various dental parameters used for the gender determination. Settings and Design: The aim of the present study was to investigate the accuracy of various methods employed in gender determination or personal identification such as mesiodistal width of molars, mesiodistal width of canine, mandibular and maxillary canine index in age group of 15 to 65 years. Methods and Material: A total of 200 patients were selected comprising of both the genders in the age group of 15-65 years belonging to various parts of Nagpur. The mesiodistal crown width of mandibular and maxillary permanent molar and canine teeth and the intercanine distance was measured and the values were noted. Statistical analysis used: the data was analysed using SPSS 18 software. Results: The mean of mesio distal width of maxillary and mandibular molar in males and females is suggestive of gender dimorphism in maxillary molars which was statistically significant. The maxillary inter-canine distance was greater in males and was statistically significant. Conclusions: The dental parameters can be used as a tool for accurate gender determination in forensic investigations.
