Peroxide bleaching agent effects on enamel surface microhardness, roughness and morphology
Tooth bleaching Peroxides Dental enamel
2009/10/20
The aim of this study was to evaluate the surface roughness, microhardness and morphology of human enamel exposed to six bleaching agents (at baseline and post-treatment). Human dental enamel samples ...
Influence of carbamide peroxide-based bleaching agents on the bond strength of resin-enamel/dentin interfaces
Peroxides Dentin-bonding agents Dentin Enamel Tensile strength
2009/10/19
In this bond strength study, a bleaching agent containing 10% carbamide peroxide was applied over composite-teeth bonded interfaces of two adhesive systems applied to enamel and dentin. Sixteen human ...
Hardness of a bleaching-shade resin composite polymerized with different light-curing sources
Composite resins Dental materials Hardness
2009/10/19
The microhardness of a bleaching-shade resin composite polymerized with different light-curing units was evaluated. Composite samples (3M ESPE Filtek Supreme) were applied to brass rings (2 mm in thic...
Effect of thickener agents on dental enamel microhardness submitted to at-home bleaching
Dental enamel Hardness tests Tooth bleaching Thickeners [adverse effects]
2009/10/19
Dental bleaching occurs due to an oxidation reaction between the bleaching agents and the macromolecules of pigments in the teeth. This reaction is unspecific and the peroxides can also affect the den...
