Abstract :
Purpose: The aim of this in vitro study was to compare the efficacy of chelating agents & Laser in removing the smear layer from root canal walls. Methodology: Sixty freshly extracted human premolar teeth with single root were selected for the study. The teeth were decoronated in such a way that the remaining root of every sample was 16 mm long. Vertical grooves were prepared on mesial and distal sides of each root. A standard conventional access preparation & instrumented using a protaper rotary files to the working length was done. the canal irrigated with 1ml of 5.25% NaOCl between files. All the samples thus were randomly divided into 4 groups and received 4 different treatment protocols. After the treatment procedures each root was split into two halves. And then examined under Scanning Electron Microscope for the presence or absence of smear layer. Results: The Scanning Electron Microscopic examination revealed most samples from EDTA group showed no smear layer and open dentinal tubules and maximum samples of LASER group showed closed dentinal tubules. Statistically significant difference was observed in EDTA group with all other groups.
