Abstract
Introduction: Mechanical instrumentation produces an irregular amorphous smear layer in the root canal system. Thus, the need to evaluate the irrigating solutions and their effect on smear layer removal.
Aim: The present study aimed to evaluate and compare the efficacy of 0.2% chitosan,17% ethylenediaminetetraacetic acid (EDTA), 10%citric acid in the removal of smear layer from the root canal system.
Materials and methodology: 45 mandibular premolars with single rooted tooth were selected. Crown down technique was used with rotary protaper next instruments and irrigation intermittently with 3% sodium hypochlorite after every instrument used. Depending on the final irrigation solution, the samples were divided randomly into three groups(n-15) group 1-0.2% chitosan, group 2-17% ethylenediaminetetraacetic acid (EDTA), group 3-10% citric acid. Teeth were then decoronated and sectioned longitudinally. Scanning electron microscope examination of canals was done for evaluating smear layer at different levels at X2000.
Result: The present study showed no statistically significant difference between 0.2% chitosan and 17% EDTA for smear layer removal from different tooth levels but there was statistically significant with 10% citric acid.
Conclusion: Final irrigation using 0.2% chitosan remove smear layer similar to 17% edta, 10% citric acid showed least effective in smear layer removal. However, the efficacy of removing the smear layer is greater when a low concentration of 0.2% chitosan was used.
