Objective This study was designed for the chemical activation of a 35% hydrogen peroxide (H2O2) bleaching gel to increase its whitening effectiveness and reduce toxicity. Methodology First, - associated or not with ferrous sulfate (FS), manganese chloride (MC), peroxidase (PR), catalase (CT) applied (3x 15 min) enamel/dentin discs adapted artificial pulp chambers. Then, odontoblast-like MDPC-23 cells were exposed 1 h extracts (culture medium + components released from product), assessment...
Abstract Aim To assess the initial cytotoxicity and late phenotype marker expression of odontoblast‐like cells ( MDPC ‐23) subjected to less aggressive in‐office bleaching therapies. Methodology A 17.5% hydrogen peroxide (H 2 O ) gel was applied for 45, 15 or 5 min enamel/dentine discs adapted trans‐wells positioned over cultured ‐23 cells. No treatment performed on negative control. Immediately after bleaching, cell viability, gene inflammatory mediators quantification H diffusion were...
Abstract This study evaluated the effect of different concentrations alpha‐tocopherol in gel form on fracture strength, hybrid layer formation, and microtensile bond strength endodontically treated teeth bleached with 40% hydrogen peroxide (H 2 O ). Sixty bovine incisors were randomized into one six groups ( n = 10 per group) defined by interventions carried out after endodontic treatment. In control group, no additional intervention was out, while all five H subsequently at 15% (15AT), 20%...
The tooth/restoration interface may act as a pathway for hydrogen peroxide (H2O2) diffusion into the pulp chamber. Therefore, influence of resin-modified glass ionomer cement (RMGIC) and resin composite simulated restorations on cytotoxicity an in-office bleaching gel was assessed in vitro.Cavities enamel/dentin discs restored with RMGIC Vitremer (3M ESPE) or Single Bond/Filtek Z350 (RC) were subjected not to hydrolytic degradation (HD). A 35%-H2O2 applied nonrestored enamel surfaces,...
Avaliou-se o efeito de diferentes agentes limpeza (etanol 95% - E ou xilol X) e momento do condicionamento ácido – CA (imediato I após 7 dias T) na interface adesão resistência união sistema adesivo condiciona-e-lava em dentina impregnada com cimentos à base resina epóxi (R) silicato cálcio (S). Cem espécimes coroas incisivos bovinos (protocolo n.o 12/2014 CEUA/FOAr-UNESP) foram preparados impregnados os cimentos. Para avaliar a formação da camada híbrida, restaurados composta, tiveram suas...
