“…The uncertainty associated with the accuracy of freehand trephine-based anaesthetic drilling is the single most significant factor why dentists still defer from using this modality in acutely inflamed pulp cases (Bangerter et al, 2009). A novel method to deliver intraosseous anaesthesia using dynamic navigation technology might be significantly safer and accurate in comparison with freehand intraosseous drilling (Jain et al, 2020).…”

To examine the efficacy rate of four anaesthetic protocols in mandibular first molars with symptomatic irreversible pulpitis (SIP).Methodology: One hundred and sixty patients with a diagnosis of SIP were included in this randomized clinical trial. Patients were randomly allocated into four treatment groups (N = 40) according to the administered technique: Group 1 (IANB): standard inferior alveolar nerve block (IANB) injection; Group 2 (IANB + IO): standard IANB followed by a supplemental intraosseous infusion (IO) injection; Group 3 (IANB + PDL): standard IANB followed by a supplemental periodontal ligament (PDL) injection; Group 4 (IANB + BI): standard IANB followed by a supplemental buccal infiltration. Patients rated pain intensity using a verbal rating scale when the root canal treatment procedure was initiated, that is, during caries removal, access preparation and pulpectomy. Heart rate changes were recorded before, during and after each injection. The anaesthetic efficacy rates were analysed using chi-square tests, age differences using one-way anova, gender differences using Fischer Exact tests whilst heart rate changes were analysed using Kruskal-Wallis tests. Statistical significances were set at p < .05 level. Results: All the included patients were analysed. No differences in the efficacy rate were found in relation to the age or gender of the participants amongst the study groups (p > .05). IANB + IO injections had a significantly higher efficacy rate (92.5%) when compared to other techniques (p < .05), followed by IANB + PDL injections (72.5%), IANB + BI injections (65.0%), with no significant differences between the IANB + PDL or IANB + BI injections (p > .05). IANB injection alone had a significantly lower rate (40%) compared to the other techniques (p < .05). A transient but significant rise in the heart rate was recorded in 60% (24/40) of patients who received the IANB + IO injection compared to other groups (p < .05). Conclusions:Inferior alveolar nerve block injection alone did not reliably permit pain-free treatment for mandibular molars with SIP. The use of an additional IO supplemental injection provided the most effective anaesthesia for patients requiring emergency root canal treatment for SIP in mandibular posterior teeth.

One of the techniques available for prosthetic rehabilitation of lost teeth are implants. Earlier implants were placed in a surgically driven treatment approach. Later the idea of placing implants on the basis of prosthetically driven treatment approach was derived by introduction of computer assisted surgery. Dynamic navigation is a technique of computer assisted surgery where the operator can perform accurate, easy and flapless implant insertion surgeries even within a single day. These navigation systems are continuously evolving to achieve even better ways of implant placement. This review will briefly highlight on the details of this navigation implant surgery.

“…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.…”

Accuracy and efficiency of guided root‐end resection using a dynamic navigation system: a human cadaver study

et al. 2021

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.
