Radiopacity of flowable resin composite
نویسندگان
چکیده
Aim: The aim of this study was to measure the radiopacity of seven flowable composite resins (FCRs). Methods: The radiopacity values of Tetric EvoFlow®A3 (Ivoclar Vivadent), PermaFlo®A1 (Ultradent), Filtek Supreme XT®A3 (3M ESPE), wave®A3 (SDI), StarFlow®A2 (Danville Materials), els flow®A3op (Saremco Dental AG) and SYNERGY Nano Formula®A2/B2 (Coltène Whaledent) were determined with reference to an aluminium step wedge and an equivalent thickness of the enamel and dentine. Results: Tetric EvoFlow®A3 had radiopacity values significantly greater than the radiopacity of enamel. All tested materials had radiopacity values greater than the radiopacity of dentine and higher than a 1 mm thickness of aluminium. Conclusions: In the future, FCRs should have higher radiopacity values than the radiopacity of dentine and ideally be similar to or higher than that of the enamel in order to improve their clinical detection.

This study was designed to test the hypothesis that the flowable/dentin interface has the weakest bond and highest frequency of failure when a resin-based composite is repaired using a flowable composite. Comparing three specific groups--dentin, flowable composite, and hybrid composite-under the Kruskal-Wallis test showed that the mean bond strength values at the flowable/dentin interface and w...

Prepared root canals recei...
متن کاملReinforcement of flowable dental composites with titanium dioxide nanotubes.
OBJECTIVES Flowable dental composites are used as restorative materials due to their excellent esthetics and rheology. However, they suffer from inferior mechanical properties compared to conventional composites. The aim of this study was to reinforce a flowable dental composite with TiO2 nanotubes (n-TiO2) and to assess the effect of n-TiO2 surface modifications on the mechanical properties of...
