Abstract

Objectives: To find out the utility of using permanent maxillary first molar as a forensic tool for sex determination, and to
compare tooth size for both side in the same sex in Kurdish people.
Materials and methods: The study sample comprised 120 casts of Kurdish peoples (67 females and 53 males) from
Sulaimani city - Iraq, with age ranging from 13-33 years. The bucco-lingual (B-L) and mesio-distal (M-D) linear
measurements of the maxillary first molars were calculated using digital vernier calipers. Percentage of sexual dimorphism
was calculated.
Results: The mean values of B-L and M-D parameters were greater in males than females and greater on right side
compared to with left side. The mean values of B-L parameters showed statistically significant differences between males
and females with p ˂0.05.The differences in B-L and M-D parameters between the right and the left side were statistically
significant in males.
Sexual dimorphism amounted to 3.48%, 2.83% for the right and left bucco-lingual diameter respectively as compared to
1%, 0.91 % for right and left mesio-distal diameters of the maxillary first molars respectively.
Conclusion: The result of the study showed that the bucco-lingual diameters of permanent maxillary first molars
exhibiting significant sexual dimorphism in Kurdish sample and can be used as adjunct in sex determination
