Also, the poor oral health and developof some oral disease has previously been related to high body mass index (BMI).Aims of the study :-The the aim of this study was to indicate if any associationbetween ABO blood system and body mass index with several oral diseasesincludes gingivitis and periodontitis.Material and method :-A total of (82) subjects were included in this study collectedfrom hospital of dentistry college from February to July,2013,divided into threegroups as those with gingivitis, periodontitis, and the healthy ones considercontrol group, aged between (10 and 55 )years were selected on a random basis .ABO blood groups were detected by using slide agglutination method aftercollected of blood samples .BMI was measured for all groups.Results: The results of this study reported that blood group type (O) appear in highpercentage ( 50%) among patients group include( gingivitis and periodontitis ),andthe blood group (A)showed a high percentage ( 47.67%) in healthy group withstatistical significant differences (p <0.05) while, the least rate of blood group inoral disease group were (AB)( 7.5%) and ( O and B)(14.29%) in control. Theresults of RH factors showed a significant increase of Rh-positive in all examinedgroups. The body mass (mean ±SD) (26±3.056) kg/m2was significantly higherpatient group when compared to control(BMI= 22.71±3.241) kg/m2 with pvalue< o.o5 .while the statistical analysis revealed there were non-significantdifferences according to type of blood groups between male and female and themean of BMI not differed between gingivitis and periodontitis p>0.05.Conclusion: Significant relationships between ABO blood type and body mass indexwith most common oral disease while RH results revealed no significantdifferences were recorded between control and oral disease.
