Um estudo realizado na Noruega correlaciona o aparecimento do infarto do miocárdio com a realização de exodontia de dentes por motivo de infecção endo ou periodontal.
Vale esclarecer que a pesquisa foi feita em um grupo de indivíduos (alguns com histórico de infarto do miocárdio e outros sem) através de questionário, onde foram perguntados os motivos de haver sido feita a extração.
Portanto, o infarto não ocorreu logo após a extração…

Myocardial infarction and tooth extraction associated
Question: Are tooth extractions for dental infections compared with extractions for non-infection reasons associated with non-fatal myocardial infarction (MI)?

This was a nested case control study within the Oslo study, which began in 1972/73 with the principle aim of studying prevention and epidemiology of cardiovascular diseases.
Within the Oslo study, men who attended for examination in both 1972/73 and 2000 with a self-reported history of MI (n=548) were compared to controls (n=625) selected at random from the same cohort, and matched by five-year strata for age.
Information on history of tooth extractions and the reasons for these extractions were obtained from a self-reported questionnaire. Reasons for tooth extractions were subgrouped into infection (marginal periodontitis and apical infection) or trauma/other causes.
Investigation of the association between the reason for extraction and MI, using prospective logistic analysis, found that extractions attributed to dental infections were significant predictors for risk factors in both 1972/73 and 2000.
