A laboratory study of the adhesion of a restorative acrylic resin and a polycarboxylate cement on bovine enamel etched with fifty per cent phosphoric acid
… study was to determine whether etching of flat bovine enamel surfaces with a 50 per cent aqueous solution of phosphoric acid for 60 seconds increases the bonding of a conventional restorative acrylic resin and a new polycarboxylate cement. The test specimens were subjected to 24 hours, 30 days …

Interaction between tin/flouride-containing solutions and artificially created dental pellicles on erosion prevetion in vitro
… solutions and stannous solutions on enamel and dentin surfaces with a previously formed ADP. To characterize the protein profile of the ADP treated with the test solutions. METHODS: Phase I tested four solutions: SnCl2/NaF, NaF, SnCl2 and deionized water (DIW) (as negative control). …

Adhesion of Orthodontic Cements Formulated with Microencapsulated Remineralizing Agents
… of this study was to determine the adhesion to enamel and mechanism of failure of orthodontic bracket and band cements formulated with microencapsulated remineralizing agents. A heterogeneous polymerization technique was utilized to prepare microcapsules containing aqueous solutions of 0.8M NaF, …

Bioactive capabilities explored in polyurethane microcapsules and the inclusion into dental sealants and cement pastes
… effect of microcapsules on cement adhesion to enamel and examine if a pit and fissure sealant releasing remineralizing ions promotes enamel fluoride uptake by demineralized tooth structure. Methods. Cements and sealants that contained microcapsules with water and controls without microcapsules …

The influence of baseline hardness and chemical composition on enamel demineralization and subsequent remineralization
… Several studies have reported that harder enamel with higher contents of calcium (Ca), phosphorus (P) and fluorine (F) coupled with lower contents of carbonate (C), magnesium (Mg) and nitrate (N) was found to be more resistant to demineralization. Additionally, the hardness of dental enamel …

Effect of Bottled Water and Fluoride Toothpaste Usage on Caries Lesion Remineralization
… Early caries lesions were created in bovine enamel specimens and stratified into treatment groups based on Vickers surface microhardness (VHN). The present study followed a two (fluoride and fluoride-free toothpaste) by five (four bottled waters and tap water) factorial design. The …

Avaliação de diferentes parâmetros para irradiação do esmalte dental com o laser de CO2 visando a redução da desmineralização
Embora seja conhecido que a irradiação com laser de CO2 reduz a desmineralização do esmalte, efeitos colaterais como danos térmicos na superfície são comumente observados. A ocorrência dessas microfraturas e fissuras é um dos fatores que ainda comprometem uma utilização segura in vivo. Sendo assim, …
