Abstract

Aim

To evaluate the effect of different chelating agents on the microhardness of the superficial dentin layer of the root canal lumen.

Materials and methods

Forty-two extracted single rooted teeth were instrumented, and the roots were longitudinally sectioned in a buccolingual direction to expose the entire canal extension. The specimens were randomly distributed in four groups according to the final irrigation: Glyde File Prep (Dentsply Maillefer, Ballaigues, Switzerland), RC Help (Prime Dental Pvt. Ltd, Mumbai, India), Endo Prep RC (Stedman Anabond, Chennai, India), Dolo Endogel (Prevest Denpro Ltd, Jammu, India). A standardized volume of 50 ml of each chelating agent was used for 5 minutes. Dentin microhardness was measured with a Knoop indenter under a 50 gm load and a 15 seconds dwell time. Data was analyzed statistically by one-way analysis of variance ANOVA and post hoc multiple-comparison test at 5% significance level.

Results

Statistically significant difference was detected among the chelating agents by one-way ANOVA. Glyde File Prep and Dolo Endogel chelating agents differed significantly (p < 0.0001) in reduction of dentin microhardness from RC help and Endo Prep RC.

Conclusion

Glyde File Prep and Dolo Endogel are significantly better than RC Help and Endo Prep RC in reducing dentin microhardness.
