Abstract The aim of the study was to assess the depth of sealer penetration into dentinal tubules following different final rinses and indirectly evaluate precipitation of irrigating solutions. Methods: 52 extracted maxillary incisors were prepared to size 40/04 with 6% sodium hypochlorite irrigating solution. Following power analysis, teeth were randomly divided into 4 groups ( n = 13) according to final rinse. Group 1 - 17% EDTA, Saline and 2% Chlorhexidine solution; Group 2 - SmearOFFā„¢; Group 3 - Qmix Ā® ; and Group 4 - saline control. Obturation was performed with gutta percha and resin sealer mixed with rhodamineā€Bā€isothiocyanate dye using warm vertical compaction. Teeth were sectioned into apical, middle, and coronal thirds using Buehler diamond saw at 3, 6 and 9 mm from the apex. Sections were examined under confocal laser scanning microscopy, and images were exported to Image J software to measure the maximum depth of sealer penetration circumferentially. Data were analysed using a generalised linear model and post hoc multiple comparisons with significance set at P < 0.05. Group 3 had the highest depth of penetration. There were statistically significant differences between Groups 2 and 3 and control for all sections, Group 1 and control in apical section only. Conclusion: Recently developed final rinses produced higher sealer penetration and more patent dentinal tubules than using EDTA and chlorhexidine sequentially.
