Hai JH, et al. - Researchers conducted this investigation to assess antibiotic prescribing practices for periodontal surgery with and without bone grafting and guidelines acceptability. Through the California Society of Periodontists email listserv, an anonymous survey was distributed to periodontists. Using McNemar tests and logistic regression, outcomes were analyzed. Compared with socket preservation, guided tissue regeneration, guided bone regeneration, and sinus augmentation, practitioners were considerably less likely to prescribe antibiotics for traditional periodontal surgeries without bone grafting. Practitioners are more likely to prescribe bone grafting antibiotics and as the complexity of the procedure for bone grafting increases. The most common reason to prescribe bone grafting antibiotics was to lower the chances of developing an infection. Based on these findings, the low incidence of infection in periodontal surgery quoted in the literature, and practitioners' readiness to adopt rules, establishing evidence-based guidelines would be beneficial to the periodontal practising community.
