“…Some physicochemical properties of THFM and hydroxypropyl methacrylate (HPM) in RMGICs were also studied and compared with commercial products. These included polymerization shrinkage, exotherm, degree of conversion and mechanical properties [13,14]. The experimental THFM-containing compositions generally showed similar polymerization shrinkage and degree of conversion compared with commercial materials [14], and improved mechanical properties compared with control materials containing HEMA as a monomer [13].…”

“…Glass ionomer cements (GICs), resin-modified glass ionomer cements (RMGICs) and flowable composites have been proposed for such applications. GICs are composed of a degradable glass and a polymeric acid, and an acid base reaction phase during their setting proceduretakes place [8,9]. The benefits of the GICs' useare the chemical bond to the tooth structure, the fluoride ions release, which causes bioactivity and caries protection, and their physical properties which are similar to those of dentin [10][11][12][13].…”

A great number of different types of materials have been used in dentistry as intermediate restoratives. Among them, new resin-based bases have been released in the dental market. The present study focuses on the identification of the organic eluates released from such materials and the study of their surface microstructure in combination with their corresponding elemental composition. For this purpose, the following materials were used:ACTIVA™BioACTIVE-BASE/LINER™, Ketac™Bond Glass Ionomer, SDR™ and Vitrebond™Light Cure Glass Ionomer Liner/Base. Methanolic leachates derived from polymerized materials were analyzed by means of gas chromatography-mass spectrometry (GC-MS). Scanning electron microscopy(SEM) was used for the surface monitoring of suitably prepared specimens. The GC-MS analysis revealed the elution of twenty different substances from the three resin-based materials, while none was eluted from the glass ionomer base. The SEM analysis for Vitrebond™ presented small pits, the one for Ketac™Bond presented elongated cracks, while no voids were present for ACTIVA™BioACTIVE-BASE/LINER™ and SDR™. Moreover, the resin matrix of some dental materials may inhibit elements’ accumulation on the surface layers. Particularly, the detected organic eluents may be related to potential toxic effects.

“…Filler particles, in the case of composite resin (2), have provided the material with exceptional smoothness, brightness, strength, high resistance to abrasion (3), decreased microleakage (4), reduced polymerization contraction and working time (5). In the case of glass ionomers, the addition of methacrylate particles (6) improved the material´s solubility with different chemical substances (7).…”

BackgroundThe constant search for an improved esthetic dental material has led investigators to realize that its performance depends on the conditions where the material is used. It has been probed that the contact with mouth rinses triggers alterations, reason why the aim of this study was to identify their possible effects of it on the integrity of nanohybrid composite resin and resin modified glass ionomer.Material and MethodsA total of 144 samples were manufactured with two nanohybrid composite resins and two resin modified glass ionomer restorative materials. The specimens were immersed in one of the three mouthwashes used in the study, for a total of 1092 minutes, with intervals of contact with artificial saliva. This strategy simulates three years of constant use of mouthwashes. The samples weight and surface roughness measurement was recorded with a precision scale and profilometer, at different stages: At the beginning of the study, after 546 minutes (simulating one and a half year), and after 1092 minutes (simulating three years).ResultsThe collected data on surface roughness and weight were submitted to the analysis of variance (ANOVA), with repeated measures of three factors. The results determined shifts in values in terms of weight and roughness in all the samples. The composite resin “Grandio” group was the one that showed bigger shifts, while the glass ionomer group “Vitremer” showed stability on its structure. The evaluated mouthwashes displayed similar behavior between each other.ConclusionsThe use of mouthwashes triggered changes on the structure of both dental materials: composite resin and resin modified glass ionomer mostly associated with surface roughness. Key words:Glass ionomer, composite resin, mouthwash, roughness, degradation.

The properties of experimental resin-modified glass-ionomer luting cements (RMGICs) containing novel monomers

Abstract: All new experimental compositions demonstrated working and setting times that are clinically acceptable. The new experimental FP compositions containing THFM (especially F3 and F4) demonstrated improved mechanical properties compared to their corresponding home material.
