Bleeding risk in thrombocytopenic patients after dental extractions: a retrospective single-center study

The aim of the present study was to assess the clinical safety profile of dental extractions in patients with thrombocytopenia and explore the effectiveness of platelet transfusion before dental extractions.

This is a retrospective cohort study of patients with moderate to severe (≤100,000/μL) thrombocytopenia who underwent dental extractions in the Oral Medicine and Dentistry Clinic at Brigham and Women's Hospital from 2003 to 2019. Patients with a platelet count <30,000/μL received prophylactic preprocedure platelet transfusion. Risk and type of bleeding complication (prolonged postoperative bleeding requiring intervention with topical hemostatic agents and/or therapeutic platelet transfusions) was assessed.

Eighty-nine thrombocytopenic patients were identified. Postextraction bleeding complications occurred in 4 patients (4.4%). Surgical extractions and multiple number of extractions were significantly associated with an increased bleeding risk (P < .05), whereas prophylactic platelet transfusion and post-transfusion platelet count were not.

Dental extractions in patients with thrombocytopenia may be performed with a positive safety profile by following a comprehensive medical evaluation, thorough treatment planning, adequate surgical management, use of local hemostatic measures, and, importantly, coordination of care with the patient's medical team.
