Study of DNA damage induced by dental bleaching agents in vitro
(2006-06-01)
Dental bleaching is a simple and conservative procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies have demonstrated the risk of tissue damage from the contact of ...
Assessing the effects of hydrogen peroxide bleaching agent on the shear bond strength of orthodontic brackets
(2016-07-01)
Background: Tooth bleaching is, today, one of the most widespread cosmetic treatments in dental practice, so it is important to determine whether it can interfere with orthodontic bonding or not. Aim: The aim of this study ...
Effects of the ratio between pigment and bleaching gel on the fracture resistance and dentin microhardness of endodontically treated teeth
(2017-11-01)
Introduction: The aim of this study was to evaluate the effects of bleaching gel using 35% hydrogen peroxide (HP), associated with red carmine pigment (RC), in the 3:1 or 1:1 ratio, on fracture resistance and dentin ...
Violet LED for non-vital tooth bleaching as a new approach
(2019-12-01)
Different light sources have been used during dental bleaching procedures. More recently, a violet LED system was introduced as a promising and viable light source, which is capable to promote dental bleaching without ...
Effect of calcium hydroxide on pH changes of the external medium after intracoronal bleaching
(2011-05-01)
Aim: This in vitro study evaluated the effect of calcium hydroxide on pH changes of the external medium after intracoronal bleaching. Materials and methods: A total of 50 extracted human premolars were prepared and filled ...

Aim: This in vitro study evaluated the effect of calcium hydroxide on pH changes of the external medium after intracoronal bleaching. Materials and methods: A total of 50 extracted human premolars were prepared and filled ...
Spectrophotometric analysis of dental bleaching after bonding and debonding of orthodontic brackets
(2021-11-01)
Introduction: The aim of this study was to evaluate the bleaching effect after aging simulation in teeth submitted to bonding and debonding of orthodontic brackets. Materials and methods: For this study, 90 human premolars ...
Quality of life and stability of tooth color change at three months after dental bleaching
(Springer International Publishing, 2018)
In-Office dental bleaching efficacy assessment in function of the light exposure regime by digital colometric reflectance spectroscopy
(2011)
In-office dental bleaching has been subject of several studies. Generally those studies quantify through visual analysis, the shade reduction of the teeth submitted to different bleaching protocols (light sources, bleaching ...
