Medical Clearance for Dental Surgery in Patients with Cardiac Conditions

Cardiac Conditions Requiring Antibiotic Prophylaxis

The American Heart Association recommends antibiotic prophylaxis before dental procedures involving gingival tissue manipulation, periapical region manipulation, or oral mucosa perforation for patients with prosthetic cardiac valves, previous infective endocarditis, unrepaired or palliated cyanotic congenital heart disease, completely repaired congenital heart disease with prosthetic materials during the first 6 months after the procedure, and repaired congenital heart disease with residual defects at or adjacent to prosthetic patches or devices that inhibit endothelialization 1

The American College of Cardiology recommends that patients on antiplatelet therapies, such as aspirin, clopidogrel, and ticagrelor, should not suspend their medication for common dental treatments, as premature discontinuation of thienopyridines dramatically increases stent thrombosis risk, frequently leading to myocardial infarction or death 2
The risk of thromboembolic events from suspension of antiplatelet therapies significantly exceeds the risk of dental bleeding, and dental bleeding is typically minor, self-limited, and manageable with local hemostatic measures 2

The National Comprehensive Cancer Network recommends that any history of antiresorptive or antiangiogenic therapies must be communicated to the dentist due to medication-related osteonecrosis of the jaw risk, and a comprehensive dental and periodontal examination with radiographs should be performed before initiating bone-modifying agents 3
The American Society of Clinical Oncology recommends that teeth requiring extraction should be removed with at least 2 weeks for healing before starting bone-modifying agent therapy, and for patients receiving bone-modifying agents at oncologic doses, there is insufficient evidence to mandate discontinuation before dentoalveolar surgery 4

The National Comprehensive Cancer Network recommends that patients with a history of head and neck radiation require special consideration due to osteoradionecrosis risk, and a comprehensive dental assessment should occur prior to therapeutic-intent radiation therapy to identify and remove at-risk teeth 5
Dental extractions should occur at least 2 weeks before radiation to allow adequate healing, and teeth with poor prognosis within the radiation field should be extracted, including those with moderate-severe periodontal disease, periapical disease, severe caries, and partially erupted third molars 5

The American Association for the Study of Liver Diseases recommends that patients with cirrhosis do not require routine blood product administration before dental procedures, and for patients with INR <2.50 and platelet counts >30 × 10⁹/L, bleeding risk after tooth extractions is low 5

The American Dental Association recommends multimodal, nonnarcotic analgesia for managing acute dental pain, and for patients on dual antiplatelet therapy, avoid NSAIDs and use acetaminophen as first-line analgesia 2

The American College of Chest Physicians recommends continuing warfarin for dental extractions with local hemostatic measures, and verifying INR ≤4.0 within 24-72 hours before procedure, for patients on warfarin 6
The European Heart Journal suggests that the timing of the last DOAC dose depends on renal function and bleeding risk, with specific guidelines for simple and multiple extractions, and recommends resuming DOAC ≥24 hours post-procedure for low bleeding risk, 48-72 hours for high bleeding risk 7

The American College of Chest Physicians recommends not bridging warfarin with heparin for dental extractions, as it increases bleeding without reducing thrombosis 6
The European Heart Journal recommends considering the patient's renal function when calculating DOAC interruption timing, and documenting concomitant P-glycoprotein inhibitors, which may require additional 24-hour DOAC interruption 7

The journal Anaesthesia recommends acetaminophen as the first-line analgesic for postoperative pain management, and avoiding NSAIDs in patients on dual antiplatelet therapy 8

The World Journal of Emergency Surgery warns against assuming normal PT/aPTT excludes DOAC effect, and recommends using specific anti-Xa or anti-IIa assays if timing is uncertain 9

The Journal of Clinical Oncology recommends documenting history of head/neck radiation, and considering osteoradionecrosis risk, with high-risk teeth extracted ≥2 weeks before radiation 10
