The aim of this study was to investigate the sexual dimorphism in permanent maxillary central incisor in Kosovo Albanian population using crown linear diameters, crown module (CM) and crown index (CI). The study sample consisted of 204 dental students, selected from the Dental School, Faculty of Medicine at University of Prishtina, Republic of Kosovo. The measurements of mesiodistal (MD) and buccolingual (BL) crown diameters of left and right permanent maxillary incisor (MCI) were taken in a dental casts using electronic digital caliper Boss, Hamburg–Germany,with accuracy ± 0.01 mm. The descriptive statistics, t-test and percentage of sexual dimorphism in crown linear diameters and dental indexes of maxillary central incisor were calculated. The results showed a statistically significant difference in MD (p<0.01) and BL diameters (p<0.0001) of maxillary central incisor between males and females. BL diameter of maxillary central incisor showed greater sexual dimorphism (4.78 %) than mesiodistal diameter (2.76 %). CM presented with a higher level of sexual dimorphism (3.76 %) comparing to CI (1.89 %). The findings of this study demonstrated sexual dental dimorphism in crown linear diameters and dental indexes in maxillary central incisor in Kosovo-Albanian population.
