The aim of this study was to evaluate the effects of one in-office and two home bleaching agents on the surface roughness of a hybrid, microhybrid and nanohybrid composite resin. Three composite resins (Valux Plus, 3M ESPE, Filtek Z 250, 3M ESPE, and Herculite XRV Ultra, Kerr) and three bleaching agents (Opalescence PF, Ultradent Products, Perfect Bleach, Voco, and Perfect BleachOffice +, Voco)...

Objective: To investigate the repair bond strength of fresh and aged nanohybrid and hybrid composite resins using a universal adhesive (UA). Materials and methods: Fresh and aged substrates were prepared using two nanohybrid (Venus Pearl, Heraus Kulzer; Filtek Supreme XTE, 3 M ESPE) and one hybrid (Z100, 3 M ESPE) composite resin, and randomly assigned to different surface treatments: (1) no tr...

A nanohybrid consisting of water-soluble thioglycolic acid (TGA)-capped CdTe nanocrystals (NCs) and methylene blue (MB) was designed as a label-free luminescent signaling platform for DNA. This sensing system was identified to operate under the photoinduced electron transfer (PET) mechanism in which MB is the electron acceptor and the binding site for the designated target molecule DNA. We show...

Background and Aims: The bleaching agents can lead to color and translucency changes in composite resins. Due to the increasing use of the nano composites and the silorane-based composites, this study aimed at examining the color and translucency changes of these restorations after bleaching agents. Materials and Methods: In this experimental - laboratory study, 198 composite discs were divide...
