1. Permeability of different groups of maxillary teeth after 38% hydrogen peroxide internal bleaching
Este estudo avaliou a influência do clareamento interno com peróxido de hidrogênio (H2O2) a 38% na permeabilidade da dentina coronária de dentes anteriores superiores e pré-molares superiores. Quatorze incisivos centrais (IC), incisivos laterais (IL), caninos (C), primeiros (1PM) e segundos (2PM) pré-molares foram seccionados transversalmente e distrib

2. Determination of internal bovine dental bleaching with different bleaching agents / Determinação do grau de clareamento interno de dentes bovinos submetidos a diferentes agentes clareadores.
The purpose of this study was to evaluate the bleaching effect of 37% carbamide peroxide, sodium perborate mixed with distilled water and sodium perborate mixed with 35 hydrogen peroxide on artificially stained pulpless teeth. Eighteen bovine teeth were sectioned 3mm apical of the cement-enamel junction and were divided into eight groups. Four groups was dir

3. Influência da aplicação de diferentes procedimentos restauradores sobre a resistência à fratura de dentes submetidos ao clareamento dental interno com peróxido de hidrogênio a 38% e fotoativação pelo sistema LED-laser / Influence of application of different restorative materials on the resistance to fracture of teeth submitted to internal dental bleaching with 38% hydrogen peroxide photo activated by the LED-laser system
The objective of this study was evaluate the influence of different restorative procedures in the resistance to fracture of endodontically treated teeth submitted to internal bleaching procedure. Fifty central upper incisors were divided into 5 groups according to treatment: GI- healthy teeth (control); GII- endodontically treated teeth sealed with Coltosol;

4. Influence of different formulations of bleaching agents on enamel and dentin physical and chemical properties / Influencia de diferentes formulações de agentes clareadores nas propriedades fisicas e quimicas do esmalte e dentina
Section A: Effects of bleaching agents on dental enamel Since the introduction of the nightguard vital bleaching technique using 10% carbamide peroxide (10% CP), reports have evaluated the effects of bleaching agents on human enamel. Evidences show that CP is able to alter the composition and morphology of enamel substrate. In order to reduce the adverse eff
