Pre-cardiac dental treatment does not increase the risk of a
Elimination of dental sources of infection prior to cardiovascular surgery (CVS) is performed to reduce peri-operative infection and complications.

This study aims to evaluate if preoperative dental intervention is associated with an increased risk of adverse events.

A retrospective medical record review of inpatient consultations (n=1513) was performed. 738 consults met the inclusion criteria and were divided into 4 groups: Group A was dentally unhealthy and received the surgical dental intervention, Group B was dentally unhealthy and underwent non-surgical dental treatment, Group C was dentally unhealthy and did not receive the recommended dental treatment, and Group D was dentally healthy requiring no intervention. They were evaluated for major adverse events in 3 categories: dental complications, medical complications, and death.

- Dental complications were only experienced in Group A, all of which were bleeding. Only 2 patients were found to have major bleeding, which was more likely due to anticoagulation and CVS rather than dental extractions.

- There was no significant difference in the number of medical adverse events or number of deaths during the post-operative period between groups.

The results of this study suggest that the elimination of oral infection prior to CVS does not increase the risk of morbidity or mortality.
