Abstract

Background: Blood groups may be associated with some diseases, deformities and, malocclusion and may have genetical relationship in general. Some studies showed that the relationship exists whereas others could not find any relationship. Therefore, this study is carried out to explore the relationship between blood group and malocclusion
Materials and Methods: This sample of 132 subjects consisted of 56 males and 76 females reporting to the department of orthodontics for treatment of malocclusion. These samples were divided into Class I , Class II and Class III malocclusion. Patient’s blood group was determined using slide method and divided into ABO and Rh blood groups. Results were tabulated and organized based on Class I , Class II and Class III malocclusion to find out the relationship between blood groups and malocclusion
Results: This study was conducted to assess correlation between blood group using different dental and skeletal parameters. The 132 subjects selected by convenience sampling method consisted of class I -79 cases, class II -44 cases and class III -9 cases. The result showed that a statistically significant relationship exists between ABO blood groups and sagittal skeletal parametersYEN angle
Conclusion: There is an association between blood groups and YEN angle (Sagittal parameter) . B and O blood group shows statistical significance with YEN angle. And there is no association between SN-GoGn, FMA and Y axis (Vertical parameter)
