Abstract

Introduction: The present study aimed to assess the periodontal condition in the patients with various blood groups referred to the dental school, Golestan University of Medical Sciences, in 2018.

Materials & Methods: This cross-sectional study was done in 970 patients referred to the dental school, Golestan University of Medical Sciences. Medical history was obtained and blood groups were determined. The assessed periodontal indices, included gingival index (GI), clinical attachment level (CAL), and periodontal pocket depth (PPD), and there were three divided groups of patients based on it: healthy ones, patients with gingivitis, and periodontitis. Then, the probable association between the type of periodontal disease, ABO blood groups and Rh factor was analyzed by Chi-squared test. P-value of 0.05 considerations was statistically significant.

Results: Among 970 patients, the most frequent blood groups in healthy individuals, patients with gingivitis and periodontitis were Group A, B, and O, respectively. The AB blood group had the least frequency in all three groups. Rh+ factor was significantly more prevalent in all three groups. Statistically, there was a significant relationship between blood group and Rh factor with periodontal disease (p value < 0.0001, p value = 0.022).

Conclusion: According to the results, the blood groups B and O showed a higher percentage in gingivitis and periodontitis groups respectively, while the blood group AB showed the least percentage of periodontal disease. Statistically, there was a significant relationship between periodontal disease with the blood group and Rh factor.
