OBJECTIVE The study aimed to evaluate effects of air abrasion with alumina or glass beads on bond strengths of resin cements to CAD/CAM composite materials. MATERIAL AND METHODS CAD/CAM composite block materials [Cerasmart (CS) and Block HC (BHC)] were pretreated as follows: (a) no treatment (None), (b) application of a ceramic primer (CP), (c) alumina-blasting at 0.2 MPa (AB), (d) AB followe...

OBJECTIVES The aims of this investigation were to clarify the effects of finishing-time and 24 h water-storage on mechanical properties and marginal adaptation to dentin of seven modern luting cements, representing three chemical types. METHODS Bistite II, Chemiace II, Compolute, XenoCem, PermaCem, Fuji Cem and Fuji Plus were investigated with specimen sub-groups (N=10) for each property meas...

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...

In order to increase the durability of concrete in maritime environments, it is often recommended use supplementary cementing materials such as silica fume or blast furnace slag. Metakaolin, even low purity, also allows a significant improvement chloride diffusion. The aim this work was evaluate characteristics concretes based on flash metakaolin when exposed marine environment. Concretes CEM I...

Zirconia (ZrO(2)) and barium sulfate (BaSO(4)) particles were introduced into a methyl methacrylate monomer (MMA) solution with polymethyl methacrylate (PMMA) beads during polymerization to develop the following novel bone cements: bone cements with unfunctionalized ZrO(2) micron particles, bone cements with unfunctionalized ZrO(2) nanoparticles, bone cements with ZrO(2) nanoparticles functiona...

Background and Aim: Dislodgment of prosthetic crowns is a common occurrence. In such cases, recementation is a suitable treatment option. The aim of this study was to compare the retention in cementation and recementation using different resin ce-ments. Materials and Methods: In this in vitro, experimental study, 40 premolars were se-lected (n=10). They were standardized relative to some prope...

This RILEM AAR-10 concrete prism test (CPT) is a performance method for testing aggregate combinations together with various binder (i.e. composite cements or pure Portland + Supplementary Cementitious Materials; SCMs). The covers the measurement of expansion produced by alkali-aggregate reaction prisms stored at 38 °C in humid environment which accelerates alkali-silica (ASR). principle this f...

This paper presents an assessment of recycling thermally treated fluvial sediments as a supplementary cementitious material (SCM). Different calcination treatments were conducted with temperatures ranging between 450°C and 950°C. For each calcined sediment, detailed characterization was carried out. Subsequently, blended cements containing 25% (CS) prepared tested, including portlandite consump...
