Systemic antibiotics in endodontics-International questionnaire study: Choice of types, dosage, loading and duration.

The aim of the study was to investigate the systematic antibiotics (SAs) prescribing practices in the endodontic practice worldwide. 7500 general practitioners, postgraduate students and endodontists from Israel and the former Soviet Union (FSU) states were invited to fill in an online questionnaire. The first-choice SA was amoxicillin (80.12%) among the Israeli (p < 0.05) and amoxicillin + clavulanic acid (88.92%) among the FSU respondents (p < 0.05). The first-choice SA for patients with penicillin allergy was clindamycin (78.2%) among Israeli and azithromycin (35.96%) among the FSU respondents (p < 0.05). Most of the respondents from Israel as well as from the FSU reported prescribing SA for 5-7 days. Only 6.24% of the former and 2.59% of the latter reported prescribing SA until the symptoms disappeared (p > 0.05). The usage of SAs is often not in accordance with existing international guidelines and differs among different dentist's populations.

International questionnaire study on systemic antibiotics in endodontics. Part 1. Prescribing practices for endodontic diagnoses and clinical scenarios.

OBJECTIVES: Part 1 of this two-part study aims to investigate systemic antibiotics (SA) prescribing practices for various endodontic diagnoses and clinical scenarios by general practitioners, post-graduate students and endodontists in Israel and the former Soviet Union (FSU) states. MATERIALS AND METHODS: A total of 7500 dentists from Israel and FSU states were invited to fill in an online questionnaire. The questionnaire consisted the SA prescribing for endodontic diagnoses and clinical scenarios (post operative pain, post apical surgery and post avulsion). The international guidelines of the European Society of Endodontology and the American Association of Endodontists were used as the standard of correct practice. RESULTS: A total of 1310 dentists (response rate of 17.46%, 498 Israeli and 812 FSU dentists) completed the survey. The rates of prescription SA among the Israeli and the FSU respondents for non-recommended diagnoses and clinical scenarios were 24.75% and 11.42% (P>0.05), 16.57% and 16.17% (P>0.05) respectively. The rates of prescription SA among the Israeli and the FSU respondents for recommended diagnoses and clinical scenarios were 63.39% and 62.9% (P>0.05), 27.2% and 13.9% (P>0.05) respectively. CONCLUSIONS: There are gaps between the recommended protocols for prescribing SA for patients with various endodontic diagnoses and clinical scenarios and the actual practices among Israeli and FSU dentists. Continuing education of dentists must be encouraged in order to improve SA prescription practice according to international guidelines. CLINICAL RELEVANCE: When not indicated, prescription of systemic antibiotics might lead to antimicrobial resistance, while non-prescription, when required, might have negative repercussions on the patient's health. Knowledge of the prescription habits of dentists in the endodontic practice will help prevent harmful situations.
