Abstract:

Aim: Various protocols have been used to remove the smear layer and increase the patency of dentinal tubules to enhance diffusion of sealers. The aim of this study was to objectively evaluate the effect of final irrigation with EDTA or SmearClear with and without passive ultrasonic activation on the patency of dentinal tubules. Methods: Ninety single-rooted were decapitated, cleaned and shaped by ProTaper. The specimens were divided into three groups according to the final irrigant, Group 1 received final irrigation with SmearClear, Group 2 with (17 %EDTA) and a third control group did not receive final irrigation. Groups 1 and 2 were subdivided into two subgroups, Subgroup (A) were activated using ultrasonic file while Subgroup (B), received no activation. Samples were examined by scanning electron microscope. Images were analyzed using Image J to objectively evaluate the relative total surface area, average size, and number of the patent dentinal tubules. Results: Ultrasonic activation significantly increased dentinal tubules? patency measured by their relative total surface area, size and number. The surfactant in SmearClear did not significantly improve patency compared to the regular EDTA. Conclusion: Irrigant activation with ultrasonic file resulted in enhanced patency of dentinal tubules regardless the irrigant solution used.
