The objective of this project is to develop a resin-based composite containing DCPD particles (dicalcium phosphate dihydrate, CaHPO4.2H2O) to be used in minimally invasive restorations, and evaluate its efficacy in the functional (or biomimetic) remineralization of artificially demineralized human dentin, combined or not with the PILP process. DCPD particles will be synthesized by co-prec…
Calcium phosphate (CaP) nanoparticles functionalization with ethylene glycol dimethacrylete derivatives does not reduce agglomeration. Therfore, alternative strategies are necessary in order to stabilize the nanoparticles and prevent agglomeration, while creating reactive sites to improve the interaction with the composite resin matrix. Citric acid has been used as nanoparticle stabilizer…
In this project, the synthesis of calcium orthophosphate nanoparticles functionalized with ethylene glycol dimethacrylate derivatives (EGDMA, DEGDMA, TEGDMA and TETDMA) will be investigated with the purpose of obtaining particles with low agglomeration and chemical interaction with dimethacrylate-based resin matrices. The ultimate goal is the development of resin composites associating me…

The incorporation of calcium orthophosphate particles (CaP) in resin composites may assist in the remineralization of caries-affected dentin; however, it causes a decrease in the mechanical properties of the material. Particle functionalization seems to reduce this undesired effect. Experimental designs used in previous studies do not allow to state whether the observed increase in the fr…
This project aims to evaluate the effectiveness of the PILP process associated or not with a resin composite containing particles of DCPD (dicalcium phosphate dihydrate, CaHPO4.2H2O) in the functional remineralization of artificially demineralized human dentin (in vitro phase) or after selective removal of the carious tissue (in vivo phase). The composite formulation will be defined in th…
The incorporation of calcium silicate and calcium orthophosphate particles in resin materials has shown to be a promising strategy to promote dentin remineralization. The aim of the present study is to verify the effect of the addition of these particles on the degree of conversion, mechanical properties, optical properties and calcium release of experimental resin materials. In an organi…
This project aims to verify the effect of the addition of dicalcium phosphate dihydrate (DCPD) particles on the fracture toughness (KIc) of experimental composites. Composites will be formulated containing equimolar concentrations of BisGMA and TEGDMA and 40% by volume of particles in different proportions between barium glasses (reinforcement) and DCPD. Bars with central notch will be ma…
Minimally invasive restorative approaches have stimulated the search for materials capable of acting in the dentin remineralization process, not only in relation to mineral gain, but also to the functional recovery of the affected tissue. The present project aims to analyze in vitro the effect of a Conventional glass Ionomer Cement (CIV) containing or not calcium orthophosphate particles …

The synthesis of dicalcium phosphate dihydrate (DCPD) functionalized with acidic monomers (DEGDMA, citric acid, acrylic acid and methacryloyloxyethyl phosphate) is being investigated to obtain non-agglomerated nanoparticles with high chemical interaction with dimethacrylate-based resin matrices. Although the use of calcium phosphate particles on dental composites is widely studied, the ap…
The integrity of the bonded interface is a key feature in the clinical performance of composite restorations. The stress generated due to composite polymerization shrinkage may lead to interfacial gap formation and residual stress build-up on the tooth structure, increasing the risk of failure over time. This research proposal aims at investigating the influence of cavity dimensions and t…
