Summary: | Removal of smear layer from the root canal walls is important for long-standing endodontic success.
The aim of this study is to evaluate and compare smear layer removing ability among 17% ethylenediaminetetraacetic acid (EDTA), Q-MIX, and phytic acid by scanning electron microscopy (SEM).
This
experimental study assessed smear layer removal using three different irrigants. Thirty single-rooted freshly extracted human permanent premolars were collected, disinfected, and decoronated to a standardized root length of 13 mm. Root canals were cleaned and shaped till F2 universal rotary protaper at working length 1 mm short of the apex. They were randomly divided into three groups, and final irrigation was done accordingly. Group 1 (
= 10): with 1 ml of 17% EDTA, Group 2 (
= 10): with 1 ml of Q-MIX, Group 3 (
= 10): with 1 ml of phytic acid. Samples were then longitudinally sectioned and evaluated under SEM at coronal, middle, and apical levels.
Two-way analysis of variance and Tukey's
test were performed. The level of significance was set at 0.05.
Smear layer removing ability among irrigants and sections in descending order: 17 EDTA > Q-MIX > phytic acid; coronal > middle > apical.
17% EDTA showed better and promising results followed by Q-MIX and then phytic acid. |
