Oxidative Chemical Hybrid Formulations for Internal Bleaching of Endodontically Treated Teeth
REVISTA DE CHIMIE(2018)
摘要
This study aims to develop new biocompatible hybrid bleaching materials based on titanium dioxide (TiO2), silica dioxide (SiO2) and ascorbic acid (Aa) and to test the characteristics of the bleached teeth, by atomic force microscopy and compressive load at break analyses. The new bleaching agents have similar efficiency with sodium perborate but they are less aggressive towards the tooth than the peroxides. The efficiency of the novel bleaching system consists in lack of side effects, confirmed by mechanical tests.
