Abstract

Introduction: This study investigates the feasibility of integrating an ultrasonic device (US) into a dynamic navigation system (DNS) for a fully guided dynamic endodontic microsurgery (EMS) workflow. It compares the accuracy and efficiency of fully guided dynamic US + DNS to US + freehand (FH) workflow.

Methods: Thirty-eight mandibular molars were divided into two groups: US + DNS (n=19) and US + FH (n=19). CBCT scans were taken pre- and postoperatively. Bone-window cut (BWC), root-end resection (RER), root-end cavity preparation (RECP), and root-end filling (REF) were planned in the X-guide. BWC, RER, RECP, and REF were all conducted under dynamic navigation. 3D deviations were measured for BWC. Resected root length and resection angle were calculated for the RER. Frequency long-axis deviation was recorded for RECP, and REF depth was measured. Total operating time was recorded.

Results: The Fully guided US + DNS was more accurate than US + FH, showing lesser 3D deviations for BWC (p<.0001). The resected root length was ∼ 3 mm (p>.05). The RER angle was lower in US + DNS (p<.0001). RECP long-axis deviations were lesser in US + DNS (p<.05). The REF depth average was 3 mm for US + DNS and 2.78 mm for US + FH (p<.05). Both EMS workflows were time efficient for EMS, with US + FH taking less time (p<.05).

Conclusions: Within the limitations of this study, it is feasible to integrate US into a DNS for a fully guided dynamic EMS workflow. Fully guided dynamic EMS workflow improved overall EMS accuracy.

期刊介绍： The Journal of Endodontics, the official journal of the American Association of Endodontists, publishes scientific articles, case reports and comparison studies evaluating materials and methods of pulp conservation and endodontic treatment. Endodontists and general dentists can learn about new concepts in root canal treatment and the latest advances in techniques and instrumentation in the one journal that helps them keep pace with rapid changes in this field.
