Comparative Evaluation of 3 Different Irrigation Systems: 30 Gauge Blunt Ended Side Vented Needle, Endoactivator & Endovac In Removal of Ca(Oh)2 From Root Canal System- Sem Study

Abstract

To compare & evaluate three different types of irrigation system in removal of calcium hydroxide form the root canal system using 30 gauge blunt ended side vented needle, Endoactivator & Endovac. Materials and methodology: Total sixty freshly extracted human intact maxillary anteriors were collected & decoronated. Access was prepared & working length was determined using #10K file & all canals were prepared till Protaper F4 as MAF & 2.5% NaOCl was used for irrigation & dried with paper points. Metapex was injected until it was extruded through apex & access cavities were sealed with cotton pellet & temporary filling. All samples were stored at 37ᵒC & 100% relative humidity for 7 days & divided into 3 groups (n=20). Group 1: 30 gauge blunt end, side vented needle, group 2: EndoActivator & group 3: EndoVac. SEM evaluation was done & statistical analysis was performed by ANOVA & Post Hoc test. Results: In coronal third, no significant difference was seen in all three groups, whereas group 2 & group 3 were equally effective in removal of calcium hydroxide from middle third. In apical third, group 2 & group 3 performed better than group 1 in removal of calcium hydroxide. Conclusion: Endovac & Endoactivator performed better than needle irrigation in removal of Ca(OH)2 from apical third.
