Endodontic Infections and the Extent of Antibiotic Overprescription among Italian Dental Practitioners.

The objectives of this study were to evaluate the pattern of antibiotic prescription for endodontic infections (EIs) among Italian dental practitioners (DPs) and to explore the role of potential predictors of antibiotic overprescription. A nationwide cross-sectional survey was conducted between 1 April and 30 October 2019 using a structured questionnaire. Information was gathered on demographics, professional characteristics, and practices regarding antibiotic prescription for both therapeutic and prophylactic purposes. Of the 1,250 invited DPs, 563 answered the general questionnaire (response rate of 52.6%). The proportions of DPs who prescribed an antibiotic without indication for therapeutic and prophylactic purposes were 33.3% and 30.2%, respectively. Acute alveolar abscess without systemic involvement represents the clinical scenario at a high risk of overprescription for therapeutic purposes. Possible predictors of overprescribing included demographics and professional characteristics. Moreover, overprescribing was found to be higher for EIs without an indication than for the cases in which the prescription is indicated for therapeutic purposes. The odds of overprescription for prophylactic purposes were higher for cases of acute apical periodontitis and lower for cases of symptomatic irreversible pulpitis than for acute and chronic alveolar abscesses, for which prescription is indicated. The main findings of the present study provide up-to-date insight into the pattern of antibiotic prescriptions for EIs and evidence useful to identify opportunities to reduce overprescription among DPs through tailored interventions. The development of practical antibiotic prescribing guidelines with a clear description of indications and regimen ease of use is strongly needed.
