The Effect of ABO Blood Types on Periodontal Status.
OBJECTIVE
The purpose of the present study was to determine whether there was a relationship between periodontal diseases and ABO blood groups.


METHODS
This epidemiological study was carried out on 1351 subjects who were randomly selected from individuals referred to the Faculty of Dentistry clinics for periodontal treatment or for other reasons regarding dental health. The study based on periodontal condition, blood group, and medical history. The subjects were divided into three groups as those with gingivitis, periodontitis, and the healthy ones. The effects of blood subgroups on periodontal health, gingivitis and periodontitis were investigated separately.


RESULTS
A relatively higher percentage of A group patients was found in gingivitis group and relatively higher percentage of O group patients was found in periodontitis group. A significant relationship was also determined between Rh factor and gingivitis.


CONCLUSIONS
ABO blood subgroups and Rh factor may constitute a risk factor on the development of periodontal disease. However, long-term studies are needed to make a more comprehensive assessment of the effects of ABO group on periodontal diseases.
