Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Prosthodontics Summary: This study was to assess the effect of home bleaching with: 10% carbamide peroxide (opalescence), 16% carbamide peroxide (Nith white) on the surface roughness and micro hardness of the enamic hybrid ceramic compared with vita mark{u2161} feldspathic one. Materials and methods: 42 sampled were classified in to two groups: Group ({u2160}): enamic hybrid ceramic, Group ({u2161}) feldspathic ceramic and each group was futher subdivided in to three subgroups according to bleaching agents used. Subgroup (A) dises from each material immersed in distilled water and hours daily for 30 days to serve as a control. Limitation of area of gel application were made using specially constructed Teflon mold. Application of bleaching were made for 8 hours every day then discs washed and kept in distilled water for the next day till 30 days application. Then the surface roughness measurements were measured by elcometer surface guage profile tester and micro hardness measurements measured by digital display vickers Micro-hardness tester. The effect of a home-bleaching agents on the roughness and micro hardness of the two different indirect esthetic restorative materials (enamic and feldspathic) were calculated and statistically analyzed
