Abstract (2. Language):
Background: The purpose of this study was to investigate if there was an association between ABO blood group and
Rhesus factor (Rh) with dental malocclusion. Patients and methods: The sample of the current study consisted from
200 subjects (100 males and 100 females) collected at the College of Dentistry, University of Baghdad, Iraq. The
antero-posterior relationships of the maxillary and mandibular first molars in maximum intercuspation by Angle’s
classification were evaluated, the blood samples were collected. The examinations of blood grouping and Rh factor
were done using slide agglutination method. Results: In Class I, the blood group O Rh+ve (55%), had a greater
propensity for dental malocclusion. In Class II Division 1, also the blood group O Rh+ve (33%), had a greater
susceptibility for dental malocclusion. While in Class II Division 2, the blood group O Rh+ve showed the predominant
percentage of occurrence (41%). The Class III showed that the blood group O Rh+ve was the highest percentage
(38%). There was no significant correlation (P>0.05) found between males and females in all malocclusions types.
Also, there was no significant correlation (P>0.05) between all malocclusions types, blood grouping system, and
Rhesus factor. Conclusion: The percentage of occurrence of total malocclusion was highest in blood group O Rh+ve,
followed by A Rh+ve, B Rh+ve, B Rh−ve, AB Rh+ve, A Rh−ve, O Rh−ve respectively, and the AB Rh−ve was the least
percentage (O Rh+ve>A Rh+ve > B Rh+veB Rh−ve > AB Rh+ve >A Rh−ve>O Rh−ve >AB Rh−ve). There was no
significant association (P>0.05) between all malocclusion types, blood grouping system, and Rh factor.
