- Abstract
Objectives: Recent studies have shown that the most dimorphic tooth is the mandibular canine. The prime purpose of this study is to investigate the accuracy of sex determination using tooth sizes in Bangladeshi population. Methods: Sexual dimorphism was tested on 260 pair of dental cast in a Bangladesh population. We studied 6240 teeth, 3120 maxillary and 3120 mandibular permanent teeth (first molar to first molar). The mesiodistal dimension was recorded, involving the maximum mesiodistal dimension of each tooth when measurement was rendered parallel to the occlusal and labial surfaces. Results: These results showed the existence of a relative dental dimorphism (male > female mesiodistal diameters). Five mesiodistal tooth sizes variables; 12, 13,15, 42, 43 and three crown indices variables; incisor index, sum of maxillary premolars and ratio of the sum of mandibular premolar to mandibular canine, showed statistically significant differences between males and females at p < 0.05. Conclusion: Teeth alone, and relatively few teeth, can be used to "sex" forensic specimens and victims of mass disasters with a degree of success equal to or exceeding for sex determination.
