Endodontics · single question
A patient has a history of infectious endocarditis (high-risk cardiac condition). For which dental procedure do we NOT need antibiotic prophylaxis?
Show answer and explanation
Correct answer: A. Class I composite restoration (not involving gingiva)
✓ A) Class I restoration NOT involving the gingiva does NOT require prophylaxis.
AHA/ADA guidelines: prophylaxis is indicated for procedures that involve manipulation of gingival tissue, periapical region, or perforation of oral mucosa. A Class I occlusal composite preparation that does not involve the gingiva does not require prophylaxis. Orthodontic band placement (involves gingival manipulation), intraligamentary injection (delivers anesthetic directly into the PDL space), and subgingival scaling all require prophylaxis in high-risk patients.
