From the results of our meta-analysis, continuing warfarin without any dose adjustment before a dental procedure does not seem to confer an increased risk of clinically important bleeding, compared with stopping or reducing the dose of warfarin. The validity of this finding is supported by several factors. Findings for both of the prespecified bleeding outcomes were consistent: continuing warfarin was not associated with a significantly increased risk of either clinically important nonmajor bleeding (RR = 0.71, 95% CI 0.39–1.28) or minor bleeding (RR = 1.19, 95% CI 0.90–1.58). None of the 275 patients who continued warfarin experienced serious (or major) bleeding.
