Objectives: Debate on antibiotic prophylaxis in patients with infectious endocarditis has emphasized the need for reliable data on the effectiveness of antibiotic therapy in dentistry patients.
Methods: We randomly sampled 583 antibiotic prescriptions delivered by dentists working in out-patient clinics in the French department of Gironde in 1992. Two-hundred fifty-seven prescriptions were analyzed in detail after telephone contact with the prescribing practicians in coordination with infectiology experts from university hospitals.
