    Summary

    Irrigating the gingival sulcus with chlorhexidine or povidone-iodine may reduce bacteremia after dental surgery. This antiseptic irrigation complements antibiotic prophylaxis for patients at risk of bacterial endocarditis.

    Area of Science:

    • Oral Surgery
    • Infectious Diseases
    • Microbiology

    Background:

    • Bacteremia can occur after dental procedures, posing a risk for bacterial endocarditis.
    • Antibiotic prophylaxis is standard for high-risk patients.
    • The role of local antiseptics in preventing post-exodontia bacteremia requires further investigation.

    Purpose of the Study:

    • To evaluate the effect of gingival sulcus irrigation with 1% chlorhexidine and povidone-iodine on bacteremia incidence.
    • To compare antiseptic irrigation with a saline control solution.
    • To assess the efficacy of specific antibiotics against isolated microorganisms.

    Main Methods:

    • A descriptive, transversal, prospective, and comparative study.
    • Six-month study duration at a Maxillofacial Surgery department.
    • Irrigation of gingival sulcus with chlorhexidine, povidone-iodine, or saline solution post-exodontia.
    • Isolation and antibiotic susceptibility testing of 92 microorganisms.

    Main Results:

    • Antiseptic irrigation of the gingival sulcus demonstrated a potential benefit.
    • The study identified specific microorganisms and their resistance patterns.
    • Penicillin and macrolides showed efficacy for prophylaxis against isolated bacteria.

    Conclusions:

    • Gingival sulcus irrigation with antiseptic solutions is a valuable adjunct to antibiotic prophylaxis.
    • This approach is beneficial for patients at risk of bacterial endocarditis.
    • Findings support the use of penicillin and macrolides in infectious endocarditis prophylaxis.
