Antibiotic prophylaxis and infective endocarditis incidence following invasive dental procedures: a systematic review and meta-analysis
Importance: The association between antibiotic prophylaxis and infective endocarditis after invasive dental procedures is still unclear. Indications for antibiotic prophylaxis were restricted by guidelines beginning in 2007.
Objective: To systematically review and analyze existing evidence on the association between antibiotic prophylaxis and infective endocarditis following invasive dental procedures.
Data Sources: PubMed, Cochrane-CENTRAL, Scopus, Web of Science, Proquest, Embase, Dentistry and Oral Sciences Source, and ClinicalTrials.gov were systematically searched from inception to May 2023.
Study Selection: Studies on the association between antibiotic prophylaxis and infective endocarditis following invasive dental procedures or time-trend analyses of infective endocarditis incidence before and after current antibiotic prophylaxis guidelines were included.
Data Extraction and Synthesis: Study quality was evaluated using structured tools. Data were extracted by independent observers. A pooled relative risk (RR) of developing infective endocarditis following invasive dental procedures in individuals who were receiving antibiotic prophylaxis vs those who were not was computed by random-effects meta-analysis.
Main Outcomes and Measures The outcome of interest was the incidence of infective endocarditis following invasive dental procedures in relation to antibiotic prophylaxis.
Results: Of 11 217 records identified, 30 were included (1 152 345 infective endocarditis cases). Of them, 8 (including 12 substudies) were either case-control/crossover or cohort studies or self-controlled case series, while 22 were time-trend studies; all were of good quality. Eight of the 12 substudies with case-control/crossover, cohort, or self-controlled case series designs performed a formal statistical analysis; 5 supported a protective role of antibiotic prophylaxis, especially among individuals at high risk, while 3 did not. By meta-analysis, antibiotic prophylaxis was associated with a significantly lower risk of infective endocarditis after invasive dental procedures in individuals at high risk (pooled RR, 0.41; 95% CI, 0.29-0.57; P for heterogeneity = .51; I2, 0%). Nineteen of the 22 time-trend studies performed a formal pre-post statistical analysis; 9 found no significant changes in infective endocarditis incidence, 7 demonstrated a significant increase for the overall population or subpopulations (individuals at high and moderate risk, streptococcus-infective endocarditis, and viridans group streptococci–infective endocarditis), whereas 3 found a significant decrease for the overall population and among oral streptococcus-infective endocarditis.
Conclusions and Relevance: While results from time-trend studies were inconsistent, data from case-control/crossover, cohort, and self-controlled case series studies showed that use of antibiotic prophylaxis is associated with reduced risk of infective endocarditis following invasive dental procedures in individuals at high risk, while no association was proven for those at low/unknown risk, thereby supporting current American Heart Association and European Society of Cardiology recommendations. Currently, there is insufficient data to support any benefit of antibiotic prophylaxis in individuals at moderate risk

Dentists’ compliance with infective endocarditis prophylaxis guidelines for patients with high-risk cardiac conditions: A systematic review
Objective. To determine dentists' awareness and adherence to antibiotic prophylaxis (AP) guidelines for the prevention of infective endocarditis (IE) in patients with high risk heart conditions.
Study Design. A systematic literature review was performed on MEDLINE/PubMed, Scopus, Web of Science, Cochrane Library, Proquest, Embase, and Dentistry and Oral Sciences Source databases, following the PRISMA checklist. Nationwide studies based on questionnaires, surveys, and interviews completed by dentists and published since 2007 were included.
Results. From 2907 articles screened, 28 studies were selected (from 20 countries). The quality of included studies was poor due to lack of standard evaluation tools, low response rates, and lack of questionnaire validity and reliability. Approximately 75% of surveyed dentists reported being knowledgeable of AP guidelines, but only ~25% confirmed compliance with them. Reported compliance with American Heart Association (AHA) guidelines was four times higher than to the National Institute for Health and Care Excellence (NICE) recommendations. Some of the highest compliance rates were reported for national AP guidelines. Significant geographical differences were observed in the adherence to AHA guidelines and the percentage of dentists who reported seeking advice from physicians/cardiologists.
Conclusion. The literature shows important geographical differences in dentists' adherence to AP guidelines for IE prevention, although reported adherence may not reflect actual adherence
