From the Guidelines
Antibiotic prophylaxis is recommended for certain high-risk patients undergoing dental procedures that involve manipulation of gingival tissue, periapical region of teeth, or perforation of oral mucosa, with the standard regimen for adults being amoxicillin 2g orally taken as a single dose 30-60 minutes before the dental procedure, as recommended by the most recent guidelines 1. The recommended antibiotic prophylaxis regimens are as follows:
- For adults: amoxicillin 2g orally taken as a single dose 30-60 minutes before the dental procedure
- For patients allergic to penicillin: alternatives include clindamycin 600mg, azithromycin 500mg, or clarithromycin 500mg, all taken as a single oral dose 30-60 minutes before the procedure
- For children: the recommended dose is amoxicillin 50mg/kg orally (maximum 2g), or if penicillin-allergic, clindamycin 20mg/kg (maximum 600mg) Prophylaxis is primarily indicated for patients with:
- Prosthetic cardiac valves
- Previous infective endocarditis
- Certain congenital heart defects
- Cardiac transplant recipients who develop cardiac valvulopathy The rationale for prophylaxis is to prevent bacteremia from oral flora entering the bloodstream during dental procedures, which could lead to infective endocarditis in susceptible individuals, as supported by the guidelines from the European Society of Cardiology 1 and the American Heart Association 1. Some key points to note are:
- Prophylaxis is not recommended for patients with coronary artery stents, pacemakers, defibrillators, or orthopedic prostheses unless specifically advised by their specialist
- Maintaining good oral hygiene is equally important in preventing bacteremia from routine daily activities
- The guidelines emphasize the importance of focusing on the risk of adverse outcomes after infective endocarditis rather than the lifetime risk of acquisition of infective endocarditis, as stated in the ACC/AHA 2008 guideline update on valvular heart disease 1.

From the Research
Recommended Oral Antibiotic Prophylaxis for Dental Surgery
- The American Heart Association (AHA) protocol antibiotics, such as amoxicillin, are commonly recommended for oral antibiotic prophylaxis in dental surgery 2, 3.
- For patients with penicillin allergies, alternative antibiotics like clindamycin, cephalosporin, or azithromycin may be used 3.
- Amoxicillin-clavulanic acid is also a popular choice, especially for patients at high risk of developing infective endocarditis or those undergoing invasive dental procedures 4, 3.
- The decision to provide antibiotic prophylaxis is based on factors such as the type of procedure, patient's medical history, and risk of infection 5, 6.
Specific Considerations
- Patients with prosthetic joints or implants may not require antibiotic prophylaxis for routine dental procedures, unless they have a history of infection or other complicating factors 2, 6.
- Patients at high risk of developing infective endocarditis, such as those with certain heart conditions, may require antibiotic prophylaxis prior to dental procedures 2, 3.
- The use of antibiotic prophylaxis should be guided by evidence-based guidelines and individual patient needs, to minimize the risk of antibiotic resistance and unnecessary side effects 4, 6.
