Influence of aspirin on post-extraction bleeding - A clinical study

Area of Science:

• Oral and Maxillofacial Surgery
• Cardiology
• Pharmacology

Background:

• Dental extractions carry a risk of post-operative bleeding.
• Antiplatelet therapies, like aspirin, are commonly used for cardiovascular health.
• Managing antiplatelet therapy around dental procedures requires careful consideration.

Purpose of the Study:

• To evaluate the impact of continuing aspirin therapy on bleeding after dental extractions.
• To compare bleeding and clotting times in patients who continued or discontinued aspirin before surgery.

Main Methods:

• A randomized clinical study involving 200 patients aged 50-65 undergoing dental extractions.
• Patients were divided into two groups: one continuing aspirin (Group A) and one discontinuing aspirin (Group B).
• Bleeding time and clotting time were measured and analyzed using the Chi-square test.

Main Results:

• Aspirin continuing group (Group A) showed a slight increase in bleeding time (3.8 ± 0.75).
• Clotting time increased in the aspirin discontinuing group (Group B) and decreased in Group A.
• Importantly, bleeding and clotting times remained within normal physiological limits for both groups.

Conclusions:

• Discontinuing aspirin therapy for ambulatory dental procedures is generally unnecessary.
• Current evidence suggests continuing aspirin is safe and aligns with American Heart Association guidelines.
• Practitioners should consider the low risk of bleeding complications when managing patients on aspirin for dental procedures.
