4. The use of a liner under different bulk-fill resin composites: 3D GAP formation analysis by x-ray microcomputed tomography
Abstract Gap formation of composite resin restorations is a serious shortcoming in clinical practice. Polymerization shrinkage stress exceeds the tooth-restoration bond strength, and it causes bacterial infiltration within gaps between cavity walls and the restorative material. Thus, an intermediate liner application with a low elastic modulus has been advis

5. The Impact of Radiotherapy in the in Vitro Remineralization of Demineralized Enamel
Abstract Objective: To evaluate the impact of radiotherapy on enamel around restorations of glass ionomer cement (GIC) and fluoride tooth paste (FTP). Material and Methods: Eighty enamel blocks were made and randomly distributed into two groups, according to the fluoride therapy, non-fluoride tooth paste (NFTP) and FTP (n=40) and in subgroups in conformity

7. Properties of zirconia-containing glass-ionomer cement
Resumo Cimentos de ionômero de vidro (CIVs) são utilizados como materiais restauradores dentários devido à sua capacidade de aderir quimicamente ao esmalte e à dentina, baixo coeficiente de expansão térmica e compatibilidade com estruturas dentárias. No entanto, esses materiais têm baixa resistência ao desgaste e fraturas. Neste trabalho, CIVs refo

12. Clinical wear of approximal glass ionomer restorations protected with a nanofilled self-adhesive light-cured protective coating
Abstract High viscous glass ionomer cement (GIC) has gained popularity as a restorative material; however, high wear is pointed as one of the major drawbacks of this material. Protective surface coatings were developed to protect GIC from water contamination with the additional advantage of occluding any surface cracks or porosities commonly found in this ma
