Abstract

Objective: The aim of the present study was to compare the effect of different canal drying methods on apical microleakage using dye penetration method.

Materials and Method: 60 extracted teeth with single root canal anatomy were cleaned and sectioned at cement-enamel junction to maintain a standardized length of 17mm using a diamond disc. Cleaning and shaping of the samples were done with protaper universal rotary files. Teeth were divided into 4 groups based on different drying protocol i.e Absorbent paper points, Aspiration with syringe, 70% Isopropyl alcohol and Chair side made apical broach. After obturation with gutta percha and MTA fillapex as a sealer, coronal accesses were sealed with glass ionomer cement. After dipping in methylene blue dye, teeth were cut at 3mm, 6mm and 9mm levels from apex. Microleakage was assesed with dye penetration method and observed under stereomicroscope.

Statistical Analysis Used: Kruskal-Wallis and Wilcoxon signed rank tests.

Results: Isopropyl Alcohol showed minimum microleakage and Chairside made Apical Broach showed maximum microleakage.

Conclusion: Final rinse with alcohol is recommended to minimize microleakage.
