Comparative evaluation of efficacy of different irrigants for smear layer removal using SEM. An invitro study

Dr. N. Praveena

Abstract :

 Aim: The purpose of this study is to evaluate and compare the efficacy of 17% EDTA, 25% citric acid and MTAD in smear layer removal using scanning electron microscopic image analysis.

Materials and Methods: Thirty, freshly extracted mandibular premolars were procured. The teeth were decoronated to obtain working length of 17mm and  instrumentation up to 40 (K file) with 5.25% NaOCl irrigation between each file was done. The samples were divided into Groups I (17% ethylenediaminetetraacetic acid (EDTA)), II 25% citric acid and III MTAD containing 10 samples each. Longitudinal sectioning of the samples was done. Then the samples were observed under scanning electron microscope (SEM) .

Statistical Analysis: Data was analyzed statistically using Kruskal–Wallis analysis of variance (ANOVA). The level for significance was set at 0.05.

Results: The present study showed that all the three experimental irrigants removed the smear layer from different tooth levels (coronal, middle, and apical). Final irrigation with MTAD is more efficient than 17% EDTA and 25% citric acid in the removal of smear layer
