| Background: The authors sought to investigate. the relationship between the blood groups and malocclusion in group from the Egyptian population. Methods: A total of 300 students (172 females and 128 males) in the age ranges of 17 – 22 years participated in this study. A separate sheet was used as a record for each student providing complete information about their blood group type and malocclusion. The blood group of each student was first determined and then divided into four groups according to their ABO blood group into A, B, O and AB group. Inside each group we started to diagnose their type of occlusion, the presence or absence of any malocclusion followed by classifying this malocclusion. Results: Using Chi-square (x2) test with significance level was set at P ≤ 0.05, it was found that a correlation exists between the blood group and malocclusion indicating that the prevalence of malocclusions is highest in blood group A followed by O then B and the least prevalence in AB. Conclusions: The estimation of the correlation between blood groups and malocclusions showed that blood groups have an association with malocclusions with highest prevalence in blood group A followed by O, B and AB in group of Egyptian population. | ||||
