Abstract Background Acute infection/inflammation increases the risk of acute vascular events (AVEs). Invasive dental treatments (IDTs) trigger short‐term acute inflammation. Purpose The aim of this work is to critically appraise the evidence linking IDTs and AVEs. Data Sources Six bibliographical databases were searched up to 31 August 2021. A systematic review following PRISMA guidelines was performed. Study Selection Intervention and observational studies reporting any AVEs following IDT were included. Data Extraction Two reviewers independently extracted data and rated the quality of studies. Data were pooled using fixed‐effect, inverse variance weights analysis. Risk of Bias Risk of bias was assessed by the Newcastle–Ottawa Quality Assessment Scale for observational studies and the Cochrane Handbook–Rob 2.0 for randomized controlled trials. Data Synthesis In 3 out of 16 clinical studies, a total of 533,175 participants, 124,344 myocardial infarctions, and 327,804 ischaemic strokes were reported. Meta‐analysis confirmed that IDT did not increase incidence ratios (IR) for combined vascular events either at 1‐4 weeks (IR of 1.02, 95% CIs: 0.92 to 1.13) and at 5‐8 weeks (IR of 1.04, 95% CIs: 0.97 to1.10) after treatment. Limitations A high level of heterogeneity (study designs and time point assessments) was found. Conclusion Patients who received IDT exhibited no substantial increase in vascular risk over 8 weeks post treatment.
