The Effect of Four Different Irrigating Solutions on the Depth of Penetration of Various Sealers into Dentinal Tubules

Abstract

The aim of the study was to evaluate the effect of different irrigating solutions used as final irrigation on depth of sealer penetration into dentinal tubules. A total of 56 freshly extracted human single rooted teeth were mechanically prepared using M-pro rotary nickel titanium system files at the working length till # 25 taper 06 instrument at the recommended speed and torque using motor Endo-Mate DT©. The root canals then irrigated with copious saline and the canals enlarged up to size # 60 using manual k files, to standardized length of 16mm. The samples were stored in water till the time to be used. Samples were divided into three groups according to the final irrigation: - GROUP 1 (NAOCL): 5 ML of Naocl 2. % were used as final irrigant for 1 min. - GROUP 2 (CHX): 5 ML of 2% chlorhexidine were used as final irrigant for 1min. - GROUP 3 (CHITOSAN): 5ML of 0.2% OF chitosan nanoparticles were used as final irrigant for 1 min. - GROUP 4 (MTAD): 5ML of MTAD were used as final irrigant for 1 min. The root canals were finally irrigated with five ml of distilled water and then dried with paper points.
