Association between acute myocardial infarction and periodontitis: A case-control study with north Indian population.

The purpose of this study was to investigate the possibility of association between periodontitis and acute myocardial infarction among North Indian adults. Literature review indicates major knowledge gaps regarding association between AMI and periodontitis in context of north Indian population. In fact, to researcher's knowledge this study is the first study investigating the possibility of this association among North Indian subjects. This quantitative study utilized 1:1 matched case-control design. The oral health status of 40 cases (AMI patients) was compared with 40 cardiovascular healthy controls (trauma patients). After adjusting for major confounders periodontitis was found to be associated with odds ratio of 6.996. Values of Mann-Whitney U, for DMFT, CPI and LOA scores were as follows: (DMFT Z=-3.825, P=0.000), (CPI Z=-4.634, P=0.000) and (LOA Z=-4.326, P=0.000). Among the north Indian subjects of this study, researcher found strong evidence of association between periodontitis and AMI. --Leaf ii.
