introduction: biocompatibility is a desirable feature for root-end filling materials. in this study we aimed to compare a new material called cold ceramic (cc) with intermediate restorative material (irm) and mineral trioxide aggregate (mta) using methyl-tetrazolium bromide (mtt) assay. materials and methods: the materials were tested in fresh and set states: (n=108). the cytotoxicity was compa...

There are various restorative materials have been used in dentistry. Among all these restorative materials each and every material will have their own beneficial effects and harmful effects. The primary objective of this review is to evaluate the pulpal responses and the cytotoxic effects of various restorative materials used in operative and restorative dentistry. Understanding the biocompatib...

background: prompt l-pop is a self-etching dentin adhesive, which is recommended to use with both compomers and composite resins. the aims of this investigation were to determine and compare the microleakage, shear bond strength, and shear push out strength of composite and compomer to dentin with application of prompt l-pop as adhesive system. methods: after application of prompt l-pop on the ...

T success of ART as a caries management approach is supported by more than 20 years restorative dentistry. It challenges treatment concepts such as step-wise excavation and the need for complete removal of affected dentine. The ART approach so far has mainly used high-viscosity glass-ionomer as the sealant and restorative material. Cariostatic and remineralization properties have been ascribed...

We have developed a new direct construction method for core build-up starting with the hypothesis that an improvement in pullout strength and a decrease in the number of voids in the restorative material will become possible by filling a hollow fiber reinforced post with the restorative material from the bottom of the root canal. For the pullout test, the hollow post was fixed to the head of a ...

This report documents treatment and repair of three carious teeth that were restored with a new dental repair material that features the characteristics of both resin-modified glass-ionomer restorative cement (RMGI) and resin-based composite (RBC). The restorative products presented are reported by the manufacturer to be the first bioactive dental materials with an ionic resin matrix, a shock-a...

Introdouction: Due to the practical problems and time restriction issues in treating dental problems in children, there is a noticeable demand for the application of a convenient handling restorative material with acceptable physical-mechanical properties. The aim of this investigation was to evaluate Vickers microhardness of four tooth-colored restorative materials as a determining mechanical...

BACKGROUND Sandblasting particles which remain on the surfaces of dental restorations are removed prior to cementation. It is probable that adhesive strength between luting material and sandblasting particle remnants might exceed that with restorative material. If that being the case, blasting particles adhere to sandblasted material surface could be instrumental to increasing adhesive strength...

Numerous positive properties of glass ionomer cements including biocompatibility, bioactivity, releasing of fluoride and good adhesion to hard dental tissue even under wet conditions and easy of handling are reasons for their wide use in paediatric and restorative dentistry. Their biggest drawbacks are the weaker mechanical properties. An important step forward in improving GIC's features is th...

Resin-based cements have been frequently employed in clinical practice to lute indirect restorations. However, there are numerous factors that may compromise the clinical performance of those cements. The aim of this literature review is to present and discuss some of the clinical factors that may affect the performance of current resin-based luting systems. Resin cements may have three differe...
