Evaluation Of Intraradicular Smear Layer Removal By Chitosan Compared To Edta- A Systematic Review

Abstract

Background: The Smear Layer Acts As A Barrier And Prevents The Penetration Of Intracanal Medicaments Into The Dentinal Tubules, Thus Compromising The Seal And Leading To Microleakage. Chitosan Is A Natural Copolymer That Effectively Removes The Smear Layer With The Advantage Of Antimicrobial Activity And Lack Of Toxicity.

Aim: To Evaluate The Intraradicular Smear Layer Removal By Chitosan Compared To Edta Using Scanning Electron Microscopy(Sem) And Atomic Force Microscopy(Afm)

Study Design: A Systematic Review About Clinical Trials Evaluating The Intraradicular Smear Layer Removal By Chitosan Compared To Edta. Electronic And Hand Search Retrieved 42, And 38 Was Screened. The Intervention And Outcomes Were Assessed In The Study Included For The Review.

Results: Nine Studies Were Included In This Systematic Review. Four Articles Show Chitosan Has Higher Efficacy In Smear Layer Removal Than Edta. Four Articles Show Chitosan And Edta Are Equally Effective, And One Article Shows Edta Has Higher Efficacy In Smear Layer Removal. These Studies Also Show The Antibacterial Property And Biocompatibility Of Chitosan. Conclusion: Though Chitosan And Edta Are Equally Effective, Chitosan Has Greater Efficiency With The Additional Advantage Of Biocompatibility, Antibacterial, Lack Of Toxicity, And Biodegradability And Cause Less Surface Alteration To Root Dentine. Further Studies To Investigate Chitosan's Physical, Chemical And Biological Properties To Verify The Benefits Of Their Use As Root Canal Chelating Agents Are Needed.
