introduction: optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. so, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. materials and methods: in this in vitro study, six endodon...

introduction: the aim of the present experimental study was to evaluate the push-out bond strength of dorifill, epiphany and mta-fillapex sealers to root canal dentin in presence and absence of smear layer (sl). methods and materials: sixty human single-rooted teeth were selected and divided into six groups ( n= 10). the canal irrigation protocol in groups 1, 3 and 5 consisted of 2.5% naocl dur...

INTRODUCTION The aim of this study was to compare the effect of post space preparation with Gates Glidden drills or hand files on the sealing ability of gutta-percha or Resilon obturation materials. MATERIALS AND METHODS One-hundred and four single-rooted human teeth were instrumented and divided into four experimental groups (n=21 each) and two groups of positive and negative control (n=10)....

background & aim: antibacterial effect of the sealers which are used in root canal therapy is a factor which increases the rate of success in root canal therapy. the aim of this study was to compare the antibacterial effect of three sealers (zoe, ah26, dorifill) on two bacterial species, staphylococcus aureuse and streptococcus mutans immediately after mixing and one week after mixing. methods ...
