The Evaluation of Hydrogen Peroxide Bleaching of Gonometa Postica Silk
Degradasie van Gonometa postica-sy as gevolg van bleiking is nie alleen ’n belangrike probleem vir verbruikers nie, maar ook vir die vervaardiger. Die doel met die navorsing was om die effek van waterstofperoksiedbleiking op G. postica-sy te bepaal. Die spesifieke doelstelling was om die invloed van temperatuur, pH en tydsduur op waterstofperoksiedvrystelling, kleurverskil, breekkrag en styfhei...
متن کاملEvaluation of Extraradicular Diffusion of Hydrogen Peroxide during Intracoronal Bleaching Using Different Bleaching Agents
Objectives. Extra radicular diffusion of hydrogen peroxide associated with intracoronal teeth bleaching was evaluated. Methods. 108 intact single rooted extracted mandibular first premolars teeth were selected. The teeth were instrumented with WaveOne system and obturated with gutta percha and divided into four groups (n = 27) according to the bleaching materials used. Each main group was divid...
متن کاملInfluence of Temperature on the Bleaching Efficacy of Hydrogen Peroxide
Aim: The aim of this study was to evaluate the influence of temperature on the bleaching efficacy of hydrogen peroxide on chromogenic solutions from wine and tobacco. Methods: Inside optical glass cuvette, equal amounts of chromogenic solution (wine or tobacco), hydrogen peroxide 60% and ultra-pure water were mixed. Initial color readings were performed with a reflectance spectrophotometer imme...

The relationship of hydrogen peroxide exposure protocol to bleaching efficacy.
The purpose of this study was to compare two in-office bleaching methods with respect to tooth color change and level of hydrogen peroxide penetration into the pulp cavity and to evaluate relationships between penetration level and color change. Eighty extracted canines were exposed to two different bleaching regimens (conventional vs sealed bleaching technique). After exposure to 38% hydrogen ...
