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 main goal of endodontic treatment is elimination of bacteria and their by-products from infected root canals. this study compared the antibacterial effect of two different sealers, ah 26 and mta fillapex, on 4 microorganisms 24, 48 and 72 h and 7 days after mixing. methods and materials: the microorganisms used in this study consisted of lactobacillus acidophilus ( atcc 4356),...

Mineral trioxide aggregate (MTA) is a bioactive endodontic cement (BEC) mainly comprised of calcium and silicate elements. The cement was introduced by Torabinejad in the 1990s and has been approved by the Food and Drug Administration to be used in the United States in 1997. A number of new BECs have also been introduced to the market, including BioAggregate, Biodentine, BioRoot RCS, calcium-en...

Since the setting characterization of a root canal sealer has an impact on its biological behavior final obturation, this study evaluated mineral trioxide aggregate MTA-Fillapex versus MTA-Bioseal compared with epoxy resin (Adseal) sealers. Freshly mixed was inserted into mold (n = 10). The initial and times were using Vicat needle then statistically analyzed by one-way ANOVA at p < 0.05. ra...

The long-term success of root canal treatment requires the prevention bacterial leakage between walls and obturation. In this study, we compared Enterococcus faecalis in thirty single-rooted mandibular premolars divided into three groups. roots two experimental groups were obturated using a single-cone obturation technique with different bio-ceramic sealers (MTA Fillapex CeraSeal) while convent...
