MICROLEAKAGE ASSOCIATED WITH RETROGRADE FILLING AFTER ROOT END RESECTION (in vitro study)
The purpose of the study is to compare microleakage after root end resection of the two materials (MTA and Biodentine) for two different apical cavity preparation using the method of penetration of dye - 0, 2 % Rodamine B. Materials and Methods: Forty-eight extracted single-rooted human teeth were...
