Introduction: Periodontal disease is a chronic immune inflammatory response associated with both the genetic makeup and the environmental influence. The aim of this study was to determine the association of different types of blood group with periodontal disease in a defined group of Iranian patients. Materials and Methods: One hundred and forty-six persons participated in this case-control study in Shahid Beheshti University of Medical Sciences Dental School, International Branch, Tehran, Iran. The patients were divided into three groups including periodontally healthy, gingivitis, and periodontitis according to approved criteria. Patients' blood groups were determined, and the relationship between periodontal status and ABO antigens was assessed. Data was analyzed on the basis of analysis of variance (ANOVA), Chi-square test, and logistic regression. Results: Logistic regression showed that people with blood group B (compared to blood group O) was at 3.94 times greater risk for developing gingivitis. On the other hand, there was no relationship between periodontitis and ABO blood groups, sex, and types of Rh factor. It was noted that 1 year of aging is associated with a 5% rise in likelihood of periodontitis. Conclusions: People with blood group B are at a greater risk to develop gingivitis, whereas periodontitis did not show any relationship with blood groups.
