Effect of Aging on Discoloration of Two Composite Surface Sealants
Objectives: Composite surface sealants were introduced aiming to prevent or decrease the discoloration and microleakage of composite restorations. This study sought to assess the effect of aging on discoloration of two composite surface sealants. Methods: In this experimental study, 24 samples were fabricated of Fortify Plus and BisCover LV composite surface sealants (10mm in diameter and 1mm ...
متن کاملSurface discoloration of composite resins: Effects of staining and bleaching
BACKGROUND The purpose of this in vitro study was to evaluate surface discoloration of three microhybrid composite resins (Esthet•X HD, Clearfil AP-X, Gradia Direct) and five nanohybrid composite resins (Ceram•X, GC Kalore, G-aenial, Grandio, GrandioSO), after staining and bleaching procedures. MATERIALS AND METHODS The composite resins were polymerized with a curing light (Celalux II, Voco, ...
متن کاملEffect of Composite Color and Thickness on Correction of Tooth Discoloration
Objective: Selection of an appropriate shade of composite is critical in achieving an esthetic restoration. Different systems are used to assess and describe color parameters. This study aimed to assess the effect of color and thickness of Filtek Supreme (FS) and Premise (P) composite resins on correction of tooth discoloration. Methods: In this in vitro experimental study, 10 anterior teet...
متن کاملPMMA Composite Thick Films as Gas Sensors
Gas sensors play vital role in detecting, monitoring and controlling the presence of hazardous and poisonous gases in the atmosphere at very low concentrations. The composite prepared by mixing carbon black with PMMA has very good gas sensing applications. The gas sensors based on Carbon nanotube / polymer, ceramic and metal oxide, epoxide, polyimide, PMMA / BaTiO3 and SnO2 have also been devel...
