“…For sample size calculation, with two groups, a P ≤ 0.05, mean linear deviation for the dynamic navigation system (DNS) of 0.19 ± 0.20 mm and for freehand (FH) of 0.40 mm based on the previous study (Dianat et al . 2020), an effect size of 0.33 and power of 0.90, n = 19 per group was required which rounded up to 20.…”

“…Recently, a novel technology, dynamic navigation system (DNS), which is adopted from implant dentistry has been used in non-surgical endodontics for guided access cavity preparation in calcified root canals (Dianat et al 2020, 2021, Jain et al 2020a and guided intra-osseous injections (Jain et al 2020a,b). These studies revealed that compared to freehand techniques, DNS had a significantly greater accuracy (Dianat et al 2020, Jain et al 2020a. This computer-based system can guide the clinician in real time based on information generated from the patient's CBCT images.…”

Aim To determine and compare the accuracy and efficiency of a dynamic navigation system (DNS) with a freehand (FH) technique when conducting root-end resection in a human cadaver model. Methodology Forty roots in cadaver heads were included and divided into two groups: DNS (n = 20) and FH (n = 20). Cone beam computed tomography (CBCT) scans of all teeth were taken. The drilling path and depth were planned virtually to using the Xguide software (X-Nav Technologies, Lansdale, PA, USA). Osteotomy and root-end resection were done under navigation in the DNS group, and freehand under the dental operating microscope in the FH group. Post-operative CBCTs were taken. Linear deviations, angular deflection, time of operation and number of mishaps were compared with determine the accuracy and efficiency. Shapiro-Wilk, one-way ANOVA and Fisher exact tests were used (P < 0.05).Results Linear deviations, angular deflection and operation time were significantly less in the DNS group (P < 0.05). The number of mishaps was not different between the two groups (P > 0.05). Subgroup analyses revealed that the distance of >5 mm from buccal cortical plate was significantly associated with lower accuracy, increased operation time and greater incidence of mishaps in the FH group (P < 0.05), but not in the DNS group. Conclusions The dynamic navigation system was more accurate and more efficient in root-end resection in a cadaver model than the freehand technique. The distance of the roots from the buccal cortical plate had a significant negative impact on the accuracy and efficacy of the root-end resection procedure when using the freehand technique. The dynamic navigation system has the potential to be a safe and reliable technological addition to endodontic microsurgery.

“…These systems provide real-time feedback of handpiece location using a computer algorithm that simultaneously tracks handpiece motion and location, using passive optical tracking, with radiographic parameters generated from prior cone-beam computed tomography images. Here, Dianet and coworkers 7 compared a dynamic navigation system versus the freehand technique for locating calcified canals in extracted human teeth. The authors reported that linear and angular deviations, reduced dentin thickness, time for access, and the number of mishaps were all significantly improved using the dynamic navigation system group.…”
