The objective of the project will be to develop a restorative composite capable of releasing Ca2+ and OH-, which would favor the precipitation of apatite and the alkalization of the medium, contributing to the greater longevity of the restorative treatment. Four formulations containing different fractions of dicalcium phosphate dihydrate (DCPD) and bioactive glass will be evaluated in rel…
Human dentin represents an important calcified tissue in the body and plays significant roles in withstanding masticatory forces. Current restorative therapies focus on the preservation of demineralized dentin structures and the use of materials that can contribute to their remineralization. The distribution of newly formed mineral determines the recovery of mechanical properties in the r…
Calcium silicate-based cements have proven to be an efficient therapy in the context of minimally invasive restorative dentistry. Although they are promising in the dentin remineralization process, there are limitations regarding their indication as a restorative material due to their low mechanical resistance. The objective of the present study is to evaluate the remineralizing potential…

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 project's objective is to develop a restorative composite capable of releasing Ca2+ and OH-, which would favor apatite precipitation and alkalization of the medium, contributing to greater longevity of the restorative treatment. Four formulations containing different fractions of dicalcium phosphate dihydrate (DCPD) and bioactive glass will be evaluated for their degree of conversion,…
The objectives of this project are to characterize experimental composites containing different volumetric fractions of bioactive glass ceramic (VCB) or dicalcium phosphate dihydrate (DCPD) in relation to calcium release, degree of conversion, mechanical behavior and optical properties and to evaluate, in vitro, the dentin remineralization achieved with these materials. DCPD particles wil…
The development of bioactive materials aims for the greatest possible release of ions. Reducing the viscosity of the resin matrix may enable the incorporation of greater fractions of calcium-releasing particles. The objective of the present study is to evaluate the effect of the BisGMA:TEGDMA ratio and the volumetric fraction of dicalcium phosphate dihydrate (DCPD) incorporated on the phy…

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…
O objetivo do trabalho é verificar a relação entre a tensão de contração de cimentos resinosos (comerciais e experimentais) e a formação de fendas na interface cerâmica/dentina, responsáveis por sensibilidade pós-operatória e cáries secundárias em restaurações indiretas adesivas. A tensão de contração de quatro marcas de cimento resinoso será determinada para um fator C=12,5. A medida dos…
