Background: Dental clearance is routinely performed before cardiac surgery, as it is thought to be essential in reducing postoperative bacteremia and endocarditis. However, there is a lack of evidence supporting this routine.
Objectives: This study aimed to investigate the impact of dental clearance on postoperative outcomes after cardiac surgery.
Methods: This is a comprehensive review and analysis of relevant studies published between 1 January 1990 and 1 January 2023 in two electronic databases (PubMed and EMBASE). Pooled estimates in terms of relative risk (RR) or standardized mean difference were calculated according to outcome measures. Risk of bias and quality of studies were evaluated. A total of 7040 articles were found through the MEDLINE, EMBASE and Cochrane databases. Five articles were found to be eligible for inclusion in this review.
Results: There is no statistically significant benefit of preoperative dental clearance in terms of postoperative outcomes, including all-cause mortality (RR 0.92, 95% Confidence Interval [CI] 0.43–1.97), prosthetic valve endocarditis (RR 1.32, 95% CI 0.51–3.43), postsurgical infection (RR 1.02, 95% CI 0.77–1.36), and length of hospital stay (weighted mean difference 4.00, 95% CI −2.70–10.70).
Conclusions: Although the literature emphasizes the importance of preoperative dental clearance, no significant effect was seen with respect to all-cause mortality, infection, endocarditis, and length of hospital stay.
