introduction: the purpose of this in vitro study was to evaluate three common gutta-percha solvents’ effectiveness in dissolving three different types of root canal sealers. materials and methods: the solubility of three different root canal sealers (ah plus, apexit plus and endoflas fs) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). one-hundred t...

The objective of this study is to assess the cytotoxic effects of substances leached from five endodontic sealers in time periods of 0 and 24 hours on NIH 3T3 fibroblasts. It was used a medium conditioned by the sealers, subdivided in six groups namely: Control (fresh cell culture medium); SimpliFill (Discus Dental, Culver City, Calif) : EndoREZ ® (Utradent Products, Inc); EPIPHANY® (Pentron Cl...

BACKGROUND/AIM Endodontic sealers (ES) for obturation are usually prepared with a slight variation of their components both on purpose or unintentionally. Considering that fact, as well as a frequent use of compaction techniques with the applied force to gutta-percha and ES of 1-3 kg, the aim of this study was to investigate the flow of two zinc-oxide eugenol ES in regard to the applied force a...

INTRODUCTION The aim of this study was to evaluate the apical and coronal seal of endodontic filling promoted by the combined use of Sealer 26/gutta-percha, Endofill/gutta-percha and Resilon/ Epiphany. MATERIALS AND METHODS A total of 38 extracted human canine teeth were selected; 10 teeth for each test group and 4 for each control group. After conducting conventional endodontic treatment, th...
