For a patient with a cardiac condition requiring infective endocarditis (IE) prophylaxis, for which dental procedure does prophylaxis NOT need to be administered?

According to AHA/ADA guidelines, antibiotic prophylaxis for IE is required for dental procedures that involve manipulation of gingival tissue, the periapical region of teeth, or perforation of the oral mucosa. A routine Class I restoration that does not involve the gingival tissue does NOT require prophylaxis because it does not cause bacteremia. Orthodontic band placement, intraligamentary injections, and scaling and root planing all involve gingival manipulation and can cause bacteremia, therefore requiring prophylaxis in at-risk patients.
