Pre-Cardiac Dental Treatment Does Not Increase the Risk of Adverse Events

      Purpose

      Elimination of dental sources of infection prior to cardiovascular surgery (CVS) is performed to reduce perioperative infection and complications. This study aims to evaluate if preoperative dental intervention is associated with increased risk of adverse events.

      Methods

      A retrospective medical record review of inpatient consultations (n = 1513) completed by the Hospital Dentistry Service at University of California Los Angeles Medical Center from January 2011 to December 2020 was performed. Seven hundred thirty-eight consults met the inclusion criteria and were divided into 4 groups: Group A were patients that were dentally unhealthy and received surgical dental intervention (n = 265), Group B were patients that were dentally unhealthy and underwent non-surgical dental treatment (n = 14), Group C were patients that were dentally unhealthy and did not receive the recommended dental treatment (n = 29), and Group D were patients that were dentally healthy requiring no intervention (n = 430). They were evaluated for major adverse events in 3 categories: dental complications, medical adverse events and death.

      Results

      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 postoperative period between groups.

      Conclusions

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