The objective of this cross-sectional study was to evaluate the relationship between ABO blood groups and periodontal diseases.
Four hundred sixteen subjects (223 females, 193 males) were recruited according to the eligibility criteria. Periodontal examination was performed, including full-mouth plaque index (PI), bleeding on probing (BOP), clinical attachment level (CAL), and interproximal bone loss (IBL). ABO blood group patterns were determined based on self-reports, confirmed by medical records. The chi-squared test was done to evaluate the data (p < 0.05).
Out of the 416 subjects, 52.2% were blood group O, whereas 27.8% were blood group A. 46.8% of patients with blood group O had gingivitis and 49.6% had periodontitis. 31.2% of patients with blood group A had gingivitis,while 29.5% had periodontitis. The blood group with the lowest percentage among patients with gingivitis was AB, with a rate of 6.2%; in this blood group, 8.1% had periodontitis.
There is no association between periodontal diseases and ABO blood group types.
本横断面研究旨在评估 ABO 血型与牙周病之间的关系。
根据纳入标准，招募了 416 名受试者（223 名女性，193 名男性）。进行了牙周检查，包括全口菌斑指数（PI）、探诊出血（BOP）、临床附着水平（CAL）和邻间骨丧失（IBL）。根据自我报告确定 ABO 血型模式，并通过病历确认。使用卡方检验进行数据分析（p<0.05）。
在 416 名受试者中，52.2%为 O 型血，27.8%为 A 型血。O 型血患者中，46.8%患有牙龈炎，49.6%患有牙周炎。A 型血患者中，31.2%患有牙龈炎，29.5%患有牙周炎。患有牙龈炎的患者中，AB 型血的比例最低，为 6.2%；在这个血型中，8.1%患有牙周炎。
牙周病与 ABO 血型类型之间没有关联。
