Comparative evaluation of smear layer removal in root canals after using lasers using SEM analysis

Original Resesarch

Abstract

Introduction

Smear layer is comprised of organic and inorganic material and might also hold bacteria. Smear layer is generated on instrumentation of canal walls in endodontic treatment.

Aim

To identify the impact of Erbium laser irradiation on elimination of smear layer compared with routine irrigation methods.

Materials and methods

Forty-Five teeth were taken and divided into three groups . In 1 Group, cleaning with  (EDTA) and (NaOCl) done. In 2  group  Erbium laser at 1W power is used  and 3 group erbium laser at 2 W is used for disinfection of canal walls.  (SEM) images  at all the three sections of root canals are being taken removal of smear layer.

Results

There was no significant improvement between  groups 2 and 3 on smear layer removal but group 1 did not remove smear layer only.

Conclusion

Within the constraints of this study, it can be established that laser can be used as an effective technique to obtain clean canals.
