Surface Morphology Changes of Bleached Dental Ceramics

Tooth whitening is one of the most conservative procedures for increasing aesthetics patients, but effect bleaching on ceramic restorations has not been extensively studied. In this study, three dental restoration materials (polished/glazed lithium disilicate glass ceramic, leucite reinforced and zirconium dioxide ceramic) investigated in terms surface roughness changes exposed samples. Philips Zoom NiteWhite 16% carbamide peroxide, 6% hydrogen peroxide with following LED illumination Pola Office have used bleaching. The experimental investigation performed statistical analysis revealed that highest all ceramics were caused by lowest peroxide. These findings correlated well colour observed same bleached samples indicating potential as prospective agent.
