Periodontitis and acute myocardial infarction (AMI) are two diseases that share common risk factors. The role of periodontitis as an independent risk factor for cardiovascular disease has been under debate. The aim of this study was to investigate whether an association exists between periodontitis and AMI in a nondiabetic population, using multiple periodontal case definitions.


Periodontal examination was performed in 204 patients with AMI. The control group comprised 102 healthy subjects, without significant coronary disease, confirmed angiographically. Periodontitis was assessed using measurements of clinical attachment loss (CAL), probing depth and number of missing teeth. From these measurements, five different case definitions of periodontitis were generated.


Using the continuous forms of periodontal measurements, the odds ratio (95% confidence interval) of the association with incident AMI was 1.74 (1.26-2.50), 1.83 (1.10-3.17) and 1.08 (1.06-1.13) for mean CAL, probing depth and number of missing teeth, respectively. A consistent positive association was observed regardless of the case definition of periodontitis.


In this nondiabetic population, the association between periodontitis and AMI was consistent across different measurements and/or definitions of periodontitis. The strength of the association increased concomitantly with the robustness of the criteria used to define periodontitis.
