Light-activated bleaching: effects on surface mineral change on enamel.
AIM This study evaluated the in vitro effect of 35% hydrogen peroxide (HP) on surface enamel change when activated with different light curing units (LCUs). MATERIALS AND METHODS Enamel blocks (4 × 4 × 2 mm) were obtained from bovine incisors. The initial microhardness of the enamel was determined for each specimen. After this enamel blocks were randomly divided into four groups (n = 10) and ...
متن کاملEffect of fluoride containing bleaching agents on enamel surface properties.
OBJECTIVES To evaluate the effects of fluoridated bleaching agents and post-bleaching fluoridation treatment on the whitening efficiency and microhardness of bovine enamel. METHODS Twenty five freshly extracted bovine incisors were cut into halves, embedded and then divided into the following five groups: Group 1, untreated controls; Group 2, treatment with 10% carbamide peroxide (CP) bleachi...
متن کاملFluoride release of glass ionomer restorations after bleaching with two different bleaching materials
OBJECTIVE This study was designed to evaluate the effect of two bleaching agents on the fluoride release of three types of glass ionomer materials. MATERIALS AND METHODS A total of 90 specimens of the tested materials (Ketac Fil, Photac Fil and F2000) were prepared by a split Teflon ring with an internal diameter of 5 mm and thickness of 2 mm. The tested materials were applied and bleached ac...
متن کاملEffect of bleaching agents on enamel surface of bovine teeth: A SEM study
BACKGROUND This study aimed to evaluate changes in the enamel surface of bovine teeth after whitening with exogenous bleaching agents: 10% carbamide peroxide (group 1), 16% carbamide peroxide (group 2) and 35% hydrogen peroxide activated by a light-emitting diode (LED) (group 3). The evaluations were performed by scanning electron microscopy (SEM). MATERIAL AND METHODS Ninety bovine teeth wer...
متن کاملEffect of Office Bleaching Systems on Chemical Compositions of Enamel and Dentin: an in Vitro Study
Background and Aim: To determine the change in the mineral component of enamel and dentin as well as to evaluate the differences in surface texture of the same dental hard tissues following three office bleaching procedures in vitro. Materials and Methods: Sixty extracted human anterior teeth were used. Thirty teeth were used as enamel samples; the buccal surfaces of the remaining 30 teeth were...
