PR72 - Trends in Endodontic Microsurgery: Report of a Web-based Survey

Thursday, April 26
10:00 AM - 1:00 PM
Room: Exhibit Hall

Introduction: Increased utilization of the dental operating microscope (DOM), availability of microsurgical techniques and instrumentation, and adoption of cone beam computed tomography (CBCT) for surgical treatment planning has impacted the surgical practice of endodontists. This study was designed to identify current microsurgical practices among members of the American Association of Endodontists (AAE). Methods: A 24-question web-based survey was sent to active AAE members via Questions aimed to identify practices in surgical treatment planning, surgical outcome assessment, and use of microsurgical techniques. Data were analyzed (descriptive statistics, Chi-square tests, and logistic regression). Results: Response rate was 23.85%. Of the respondents, 81% were in full-time private practice; 94% performed microsurgery; 87.7% reported microsurgery as a small percentage (1-15%) of their overall practice. CBCT was utilized by 60% pre-operatively for surgical planning in all or a majority of cases. DOM was used by 95% of respondents during the intraosseous portion of the surgical procedure. Retrofills were predominantly bioceramic (93%). Grafting material was used by 63%. Postoperatively, antibiotics were routinely prescribed by 34% of respondents and Schedule 2 analgesics by 26%. Tissue was always biopsied by 51% of respondents. Decade of respondent’s residency correlated to use of microsurgical techniques, instrumentation, and use of CBCT. Conclusion: Endodontic microsurgery continues to comprise a small percentage of the private practitioners’ practice. The specialty has embraced modern endodontic microsurgery techniques, instrumentation and materials.
