introduction: the aim of this in vitro study was to compare the efficacy of protaper retreatment (protaper r) and mtwo retreatment (mtwo r) files in removing gutta-percha and guttaflow from endodontically treated straight root canals. methods and materials: the root canals of 60 human mandibular single-rooted premolars were prepared and randomly divided into two groups ( n =30). in groups a and...

introduction: root canal obturation seals the root canal system to prevent re-entry and/or growth of microorganisms. the provision of an appropriate restoration to coronally seal the access cavity affects the success of endodontic treatment. the purpose of this study was to evaluate the coronal microbial leakage in root canals that were either filled by lateral compaction, guttaflow or warm ver...

The aim of this study was to evaluate the physical properties of EndoRez, Diaket, Epiphany, Roekoseal, Fibrefill, GuttaFlow, AHPlus, AH26 to that of a traditional zinc oxide based Kerr PCS sealers. Ten samples of each material were evaluated for flow, radiopacity, solubility and dimensional change tests according to ISO standards 20016876. The findings were statistically analyzed. Radiopacity a...
