Popis:	Aim: The aim of this study was to compare the effect of EDTA with different temperatures and pH values on the penetrability of a sealer into dentinal tubules by the confocal laser scanning microscope.Materials and Methods: Forty-four single rooted extracted mandibular premolars were used. The working length was determined and then root canals were prepared with the Reciproc system. Before the final irrigation procedures, specimens were randomly distributed into 4 groups according to the temperature and pH values of EDTA (n=11): 22°C pH: 7; 22°C pH 12; 40°C pH 7; 40°C pH 12. Teeth were obturated using a labeled sealer mixed with 0.1% Rhodamine B and gutta percha as the core material. Specimens were then sectioned at 2 and 7 mm from the apex. All the sections were examined under confocal microscope to calculate the dentinal tubule peneration area. The data were analysed using linear regression analysis and Mann-Whitney U tests.Results: The linear regression analysis demonstrated that temperature and area variables had the significant effect on sealer penetration into dentinal tubules (p
