To reduce its incidence, antibiotic prophylaxis has been recommended before invasive dental procedures in patients with at risk predispositions. Several studies have examined the effect of antibiotic prophylaxis on the incidence of IE and have brought conflicting results. The investigators aim to evaluate the effectiveness of antibiotic prophylaxis before invasive dental procedures to prevent oral streptococcal infective endocarditis in patients with prosthetic heart valves and\u002For history of IE, using a registry-based, cluster-randomized, controlled trial.
