Comparative Evaluation of Efficacy of Endodontic Irrigant Delivery to Working Length using Conventional Needle Syringe, Endovac and Self-Adjusting File System on Prepared Mesiobuccal Canal of Mandibular First Molar by using Radiographic Contrast Media

Introduction: Endodontic treatment is essentially a debridement procedure, followed by sealing of pulp space and restoration of tooth. Aim: To compare the efficacy of endodontic irrigant delivery to working length using conventional needle syringe, EndoVac and Self Adjusting file system on prepared mesiobuccal canal of mandibular first molar using radiographic contrast media. Materials and Methods: 60 patients, who were scheduled for root canal treatment of Permanent First Molars, were randomly selected. The prepared mesiobuccal canals were then assigned into 3 different groups for evaluation of irrigant delivery using radiographic dye. Different irrigation protocol was performed for each group. Results: The analysis of variance test showed statistically significant differences between groups (<0.001) Tukey's honestly significant post hoc tests showed significant statistical differences between group 1 (the conventional needle and syringe irrigation) and group 2 (the EndoVac) and group 1 and group 3 (the Self-adjusting file system) (P <0.001). No significant difference was observed between group 2 and group 3 (P =0.080). Conclusion: To do a better cleaning of the root canals, the delivery systems and techniques which are proven superior and safe, such as EndoVac and Self-adjusting file should be integrated in routine clinical practice. This will not only enhance cleaning but also the quality of the final sealing and ultimately enhance overall success.
