OBJECTIVES This study attempted to find a simple adhesive restorative technique for class I and II cavities on posterior teeth. STUDY DESIGN The tested materials were a self-etching adhesive (Parabond, Coltène/Whaledent) and a dual-cure composite (Paracore, Coltène/Whaledent) used in bulk to restore the cavities. Class II MO cavities were performed and assigned to 4 groups depending on the or...

Purpose: To assess the degree of conversion (DC) dual-curing composite cements when cured through ceramic-veneered zirconia disks. Methods: Portions mixed cement, either G-CEM LinkForce (GC), Panavia V5 (Kuraray Noritake) or ResiCEM (Shofu), were placed on ATR crystal a Fourier Transform Infrared Spectroscope (FTIR; iS50, Thermo Scientific) and squeezed to 100-µm film thickness using microscopy...

The calibration of a measurement device is crucial for every scientific experiment, where a signal has to be inferred from data. We present CURE, the calibration-uncertainty renormalized estimator, to reconstruct a signal and simultaneously the instrument's calibration from the same data without knowing the exact calibration, but its covariance structure. The idea of the CURE method, developed ...

OBJECTIVES The absorption of water by acrylic resins is a phenomenon of considerable importance since it is accompanied by dimensional changes, a further undesirable effect of absorbed water in acrylic resins to reduce the tensile strength of the material. Solubility is also an important property because it represents the mass of soluble materials from the polymers. METHODS Ten acrylic resin-...

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 ...

This study evaluated the Knoop Hardness (KHN) values of two dual-cured composite resin core build-up materials and one resin cement exposed to different curing conditions. Two dual-cured core build-up composite resins (LuxaCore-Dual, DMG; and FluoroCore2, Dentsply Caulk), and one dual-cured resin cement (Rely X ARC, 3M ESPE) were used in the present study. The composite materials were placed in...

Abstract Aim The purpose of this study was to compare and evaluate the flexural strength modulus elasticity three adhesive luting cements as a function specimen age, effect storage media, curing through porcelain. Materials Methods Twenty samples fabricated for self-cure resin-modified glass ionomer cement (GIC; RelyX Luting 2, 3M ESPE, United States) were classified group 1, whereas 40 two dua...
