Periodontal Diseases and Salivary Secretion of ABH Blood Antigens in Yemeni Patients

Abstract

This study explored the secretion trait as a risk factor for periodontal disease progression. 162 patients suffering from periodontal disease attended the Outpatient Dental Clinics at the Faculty of Dentistry, Ibb University, and 69 healthy volunteers were enrolled in this study. Clinical evaluation for periodontal disease was carried out according to international guidelines and expressed by pocket probing depth (PPD), bleeding on probing (BOP), and clinical attachment level (CAL) parameters. A blood sample was collected and tested for blood grouping test, and a saliva sample was analyzed for secretion using hemagglutination inhibition test. Secretor patients were 82% compared with 64% of healthy control. Mean score of BOB and PPD and the clinical magnitude of CAL parameters were increased within secretors. The development of periodontal diseases increased among secretors by 2.61 times more than non-secretors (OR = 2.61, CI, 1.382–4.914, p = 0.004). Significant periodontal complaints associated with secretion are Bleeding gums (OR = 1.95, CI, 1.011–3.759, p = 0.049), malaligned teeth (OR = 4.49 (CI, 1.842–10.958), p = 0.0001), gingival recession (OR = 2.48, CI, 1.322–4.648, p = 0.007), and teeth decay (OR = 1.86, CI, 1.006–3.438, p = 0.05). Secretion of ABH antigens is risk factor for progression of periodontal diseases. The odds of periodontal complaints, bleeding gums, malaligned teeth, gingival recession, and tooth decay prove the ABH secretion effect.
