Introduction
Safety of dental extractions in patients on chronic antiplatelet therapy either with only acetylsalicylic acid (ASA) or clopidogrel or with both combined has been a matter of debate, with no clearly conclusive studies published.

Aim
To perform a meta-analysis of published observational studies in order to study the effect of single and double antiplatelet therapy in comparison to controls on the occurrence of immediate local bleeding complications during dental extractions.

Material and methods
PubMed/Scopus/Embase database search revealed 22 papers (13 original and 9 review), 3 of which were finally included in the meta-analysis. Phrases searched: dual[All Fields] AND antiplatelet[All Fields] AND (“therapy”[Subheading] OR “therapy”[All Fields] OR “therapeutics”[MeSH Terms] OR “therapeutics”[All Fields]) AND (“tooth extraction”[MeSH Terms] OR (“tooth”[All Fields] AND “extraction”[All Fields]) OR “tooth extraction”[All Fields]).

Results
The overall event incidence (bleeding complication after extraction) in the entire population was 1.59% (42 events in 2637 patients). As compared to the control group, the use of double antiplatelet therapy DAPT was associated with on odd ratio OR of 40.23 (95% CI: 4.37–370.36) increase in risk of bleeding events occurrence (p = 0.0011). Significant heterogeneity was observed (p < 0.001; I2 of 76.7%).

Conclusions
Dental extractions following strict procedural protocols in patients on double antiplatelet therapy with clopidogrel and ASA are associated with an additional risk of immediate local bleeding complications.
