Abstract
BACKGROUND: The risk of excessive bleeding often prompts physicians to interrupt the antiplatelet agents as acetylsalicilyc acid and clopidogrel before dental extractions which puts patients at risk of adverse thrombotic events. AIM: To assess the bleeding risk during dental extractions in patients with continued antiplatelet therapy. MATERIALS AND METHODS: The study included 130 patients (64 men and 66 women) aged between 18 and 99 years old. Sixty-eight of the patients received 100 mg acetilsalicilic acid (ASA); these were divided into two groups: 34 patients continued taking ASA and 34 patients stopped it 72 hours before extraction. Sixty-two of the patients were treated with 75 mg clopidogrel; these were also divided into two groups: 31 continued taking clopidogrel and 31 patients stopped it 72 hours before extractions. Extraction was performed under local anaesthesia as no more than 3 teeth per visit were extracted. Local haemostasis with gelatine sponge and/or suturing was used to control bleeding. RESULTS:Mild bleeding was observed most frequently in the first 30 minutes, successfully managed by local haemostasis. Only 1 patient in the control and 1 in the experimental group receiving ASA reported mild bleeding in the first 24 hours, controlled by compression with gauze. No major haemorrhage requiring emergency or more than local haemostasis occurred. No statistically significant difference in bleeding between two groups was found. CONCLUSION: Single and multiple dental extractions in patients receiving acetylsalicylic acid or clopidogrel can be safely performed without discontinuation of the therapy with provided appropriate local haemostasis.
