Accumulating evidence has shown a significant correlation between periodontal diseases and systemic diseases. In this study, we investigated the association between the frequency of tooth scaling and acute myocardial infarction (AMI). Here, a group of 7164 participants who underwent tooth scaling was compared with another group of 7164 participants without tooth scaling through propensity score matching to assess AMI risk by Cox's proportional hazard regression. The results show that the hazard ratio of AMI from the tooth scaling group was 0.543 (0.441, 0.670) and the average expenses of AMI in the follow up period was USD 265.76, while the average expenses of AMI in follow up period for control group was USD 292.47. The tooth scaling group was further divided into two subgroups, namely A and B, to check the influence of tooth scaling frequency on AMI risk. We observed that (1) the incidence rate of AMI in the group without any tooth scaling was 3.5%, which is significantly higher than the incidence of 1.9% in the group with tooth scaling; (2) the tooth scaling group had lower total medical expenditures than those of the other group because of the high medical expenditure associated with AMI; and (3) participants who underwent tooth scaling had a lower AMI risk than those who never underwent tooth scaling had. Therefore, the results of this study demonstrate the importance of preventive medicine.
越来越多的证据表明，牙周病与全身性疾病之间存在显著相关性。本研究通过倾向评分匹配比较了 7164 名接受洁牙治疗的参与者和 7164 名未接受洁牙治疗的参与者，以评估 Cox 比例风险回归分析中牙周病治疗与急性心肌梗死（AMI）之间的关联。结果表明，从洁牙组发生 AMI 的风险比为 0.543（0.441，0.670），在随访期间发生 AMI 的平均费用为 265.76 美元，而对照组在随访期间发生 AMI 的平均费用为 292.47 美元。进一步将洁牙组分为 A、B 两组，以检查洁牙频率对 AMI 风险的影响。我们观察到（1）未接受任何洁牙治疗的组中 AMI 的发生率为 3.5%，明显高于接受洁牙治疗组中 1.9%的发生率；（2）由于 AMI 相关的高额医疗支出，洁牙组的总医疗支出低于其他组；（3）接受洁牙治疗的参与者比从未接受洁牙治疗的参与者发生 AMI 的风险更低。因此，本研究的结果证明了预防医学的重要性。
