Prescribing trends of systemic antibiotics by periodontists in Australia

Background Antibiotics are a common systemic pharmaceutical therapy in periodontal conditions for dental practitioners as well as specialists. However, there is limited information about prescribing patterns amongst the periodontists within Australia. The objective of this study is to examine current patterns and perceptions in prescribing systemic antibiotics for the treatment of periodontal and peri-implant diseases. Methods An online questionnaire was disseminated to Australian practicing members of the Australia and New Zealand Academy of Periodontists (ANZAP) to determine their antibiotic prescribing patterns for different periodontal conditions. Indications that were analyzed included: chronic periodontitis, plaque-induced gingivitis, aggressive periodontitis, acute gingival and periodontal conditions, conditions associated with implants and implant placement, periodontal regeneration, and mucogingival surgery. Results Out of the 50 members that participated in the study, 38 completed the questionnaire. Systemic antibiotics prescription patterns varied markedly for different periodontal or peri-implant diseases among respondents. 79% reported prescription of systemic antibiotics in the treatment of chronic periodontitis whereas 52.6%, 55.3%, 18.4% of the respondents did so for periodontal regeneration procedures, implant placement surgery, and mucogingival surgery, respectively. Azithromycin, the combination of Amoxicillin and Metronidazole, and Amoxicillin were the three most commonly prescribed systemic antibiotics. Conclusion Based on the results of this survey, systemic antibiotics are widely used by the group of periodontists surveyed in this study in Australia with varying rates and patterns for different periodontal and peri-implant conditions. The current study highlights the need for recommendations and guidelines in the prescription of antibiotics for periodontal and peri-implant conditions.
