Key result
Prophylactic antibiotics reduce bacteremia after dental procedures ~76% but lack sufficient evidence for preventing IE.
Why the study?
To assess the effectiveness of prophylactic antibiotics in preventing infective endocarditis after dental procedures in pediatric patients with congenital heart disease.
Does antibiotic prophylaxis prevent infective endocarditis or bacteremia in pediatric patients with congenital heart disease undergoing dental procedures?
Population
Pediatric patients with congenital heart disease undergoing dental procedures across 3 included case-control studies
Comparison
Antibiotic prophylaxis before dental procedures vs no antibiotic prophylaxis
Design
Systematic review of 3 case-control studies

Insufficient evidence to guide IE prophylaxis in congenital heart disease; leaves open need for trials linking bacteremia reduction to endocarditis outcomes.
Systematic Review
Does antibiotic prophylaxis prevent infective endocarditis or bacteremia in pediatric patients with congenital heart disease undergoing dental procedures?
Odds Ratio: 0.24 (95% CI 0.14–0.42)
p-value: p=<0.05
Current evidence is insufficient and of very low certainty to conclude whether prophylactic antibiotics prevent infective endocarditis in children with congenital heart disease undergoing dental procedures.
Loper et al. (2025) conducted a systematic review in Congenital heart disease. Prophylactic antibiotics vs. No antibiotic prophylaxis was evaluated on Bacteremia after dental procedures (Pooled OR 0.24, 95% CI 0.14-0.42, p=<0.05). Prophylactic antibiotics reduced bacteremia after dental procedures (Pooled OR 0.24; 95% CI 0.14-0.42; P<0.05), though evidence for preventing infective endocarditis was insufficient.
