The use of additives to improve the quality of cement grouts is crucial for civil engineering, especially in foundation construction. This article presents experimental data concerning the compressive strength, elastic modulus, bleeding and injectability of microfine cement grouts modified with epoxy and acrylic resin emulsions. Strength properties were obtained at different curing ages. For fu...

The prevalence of stomatitis, especially caused by Candida albicans, has highlighted the need of new antifungal denture materials. This study aimed to develop an antifungal heat-curing resin containing quaternary ammonium monomer (dimethylaminododecyl methacrylate, DMADDM), and evaluate its physical performance and antifungal properties. The discs were prepared by incorporating DMADDM into the ...

4-META/MMA-TBB resin has clinically favorable mechanical and bonding properties and undergoes unique, moisture-insensitive polymerization. To explore the potential usefulness of 4-META/ MMA-TBB resin as a pulp capping material, this study examined its biological and biochemical properties. Rat dental pulp cells were cultured on 4-META/MMA-TBB resin, resin-modified glassionomer (RMGI) cement, an...

OBJECTIVE TiO(2) nanoparticles treated with the organosilane allyltriethoxysilane (ATES) are used to improve the mechanical properties of dental resin-based composites (RBCs, Z100, 3M ESPE). METHODS TiO(2) nanoparticles were sonically dispersed in an ethanol solution containing ATES. The modified particles were washed in pure ethanol and dried before being used as filler. Fourier transform in...

A resin monomer-soluble polyrotaxane (PRX) crosslinker with cleavable end groups was synthesized to develop degradable photosetting composite resins. The PRX containing 50 α-cyclodextrins (α-CDs) with disulfide end groups was initially modified with n-butylamine to obtain a resin monomer-soluble PRX. The PRX containing 13 n-butyl groups per α-CD molecule was completely soluble in conventional r...

The removal of Pb(II) from aqueous solutions by using modified Amberlite XAD-7HP resin has been studied. The resins have been prepared by complete mixing of Amberlite XAD-7HP resin with anionic surfactant-dioctyl sodium sulphosuccinate (DOSSS) and EDTA-disodium salt (Chelating agent) in an aqueous solution. SEM studies revealed the morphological observations of the unloaded adsorbent and thereb...

The present study aimed to compare the fluoride (F-) release pattern of a nanofilled resin-modified glass ionomer cement (GIC) (Ketac N100 - KN) with available GICs used in dental practice (resin-modified GIC - Vitremer - V; conventional GIC - Ketac Molar - KM) and a nanofilled resin composite (Filtek Supreme - RC). Discs of each material (n=6) were placed into 4 mL of deionized water in sealed...

PURPOSE This in vitro study compared bond strength and fracture modes of tooth-colored restorations in 2 types of cavity preparations in human primary molars. METHODS Standardized Class II cavities (40 dovetail and 40 box-only preparations) in extracted human primary molars were restored with packable composite resin (PC), resin-modified glass ionomer cement (RMGIC), resin-modified glass iono...
