PURPOSE To evaluate the degree of conversion (DC) of dual-curing materials used to lute glass-fiber posts in a simulated root canal polymerized by two different modalities. METHODS Artificial root canals were used to simulate a clinical condition to lute 45 posts by three different dual curing luting cements (Calibra, Multilink Automix and Variolink II). Two light cure modalities were chosen ...

OBJECTIVE To evaluate the effects of etch-and-rinse and self-etching adhesive systems on Vickers hardness (VHN) uniformity of dual-cured resin cements after fiber post cementation. METHODS FIFTY GLASS FIBER POSTS WERE CEMENTED INTO BOVINE ROOTS USING THE FOLLOWING CEMENTING SYSTEMS: Prime&Bond 2.1 Dual Cure and Enforce with light-activation (PBDC-LCEN); Prime&Bond 2.1 and Enforce with light-a...

in this note we consider the notion of intuitionistic fuzzy (weak) dual hyper k-ideals and obtain related results. then we classify this notion according to level sets. after that we determine the relationships between intuitionistic fuzzy (weak) dual hyper k-ideals and intuitionistic fuzzy (weak) hyper k-ideals. finally, we define the notion of the product of two intuitionistic fuzzy (weak) du...

The colour properties of resin luting agents (RLAs) can influence the aesthetic an indirect restoration. This in vitro study aims to evaluate stability and translucency RLAs cured using two different protocols by means a spectrophotometer. Six were investigated: Enamel Plus Flow (MF), (MH), light-cure Nexus Third Generation (NX3L), dual-cure (NX3D), RelyX Veneer (RXL) Ultimate (RXD). samples ra...

Introduction and Aim: Cention N is an “alkasite” restorative material which utilizes alkaline filler capable of releasing acid-neutralizing ions. These ions can be helpful in buffering the pH saliva, thus preventing carious activity. Hence this study was undertaken to investigate action Cention-N material. Materials methods: Solutions distilled water with values adjusted approximately 5.5, 6.5 ...
