1. The interaction of polyacid-modified composite resins ("compomers") with aqueous fluoride solutions
OBJECTIVE : The aim of this study was to investigate how the release of fluoride from two compomers and a fluoridated composite resin was affected by exposure to KF solution. MATERIAL AND METHODS: Two compomers (Dyract AP and Compoglass F) and one fluoridated composite (Wave) were prepared as discs (6 mm diameter and 2 mm thick), curing with a standard denta

2. Marginal adaptation and performance of bioactive dental restorative materials in deciduous and young permanent teeth
OBJECTIVE: The aim of this study was to investigate the adaptation of different types of restorations towards deciduous and young permanent teeth. MATERIAL AND METHODS: Class V cavities were prepared in deciduous and young permanent teeth and filled with different materials (a conventional glass-ionomer, a resin-modified glass-ionomer, a poly-acid-modified c

3. Efeito de materiais restauradores fluoretados no desenvolvimento de carie secundaria em dentina redicular
In vitro studies have shown that fluoride containing restorative materials can inhibit root dentin secondary caries. However, questions still arise on the potential of some restorative materials, on the extension of the cariostatic effect from the restoration margins and on the in vivo ability of such materials to prevent secondary root caries. This thesis,

4. Microhardness of esthetic restorative materials at different depths
The aim of this study was to analyze the microhardness of two resin-modified glass ionomer cements (Vitremer; Fuji II LC); two polyacid-modified composite resins (Freedom; F2000) and a hybrid composite resin (Prodigy), at different depths from the upper surface. Six hemi-cylinders (3 mm height; 3 mm radius) per tested material were obtained. Vickers Hardness

5. Infiltração marginal em restaurações de compositos com diferentes viscosidades polimerizados sob intensidade gradual da luz visivel
The purpose this study was to evaluate the marginal leakage of cavities restored with resin composites of different viscosities. Composites with high viscosity (Sure FiI), low viscosity (Tetric Flow) and medium viscosity (TPH Spectrum), and polyacid modified resin (Dyract AP) were evaluated. Sixty-five class V cavities were prepared on freshly extracted huma

7. Avaliação in vitro da liberação de fluoretos de duas resinas compostas modificadas por poliacidos e um ionomerico modificado por resina
Muitos estudos demonstram a liberação de fluoretos dos cimentos de ionômero de vidro modificados por resina e de resinas compostas modificadas por poliácidos. Os efeitos anticariogênicos dos fluoretos têm levado a sua incorporação em um grande número de materiais dentários. O objetivo deste estudo foi quantificar e comparar in vitro a liberação d

8. Avaliação da deposição superficial do corante evidenciador de placa bacteriana em materiais hibridos de ionomero de vidro/resina composta
he purpose of this study was to evaluate the influence of the plaque disclosing in the staining of two glass-ionomer / composite resin hybrid materiaIs, by spectrophotometric method. The restorative materiaIs used were: Vitremer, Variglass and the basic fuhcsine solution at 0.5 % as the disclosing agent. Ninety specimens were randomly assigned in 3 equal gro
