Surface changes of restorative materials after bleaching have clinical importance in terms the durability and survival restorations. This study aimed to evaluate effect home on surface roughness, microhardness, analysis four different types chairside computer-aided design manufacturing (CAD/CAM) materials. Specimens were prepared from composite resin (Brilliant Crios: BC), nanoceramic (Lava Ult...

background: the purpose of this study was to evaluate the influence of three different luting protocols on shear bond strength of computer aided design/computer aided manufacturing (cad/cam) resin nanoceramic (rnc) material to dentin. materials and methods: in this in vitro study, 30 disks were milled from rnc blocks (lava ultimate/3m espe) with cad/cam technology. the disks were subsequently c...

Transparent Ce:lutetium aluminum garnet (Ce:Lu3Al5O12, Ce:LuAG) ceramics have been regarded as potential scintillator materials due to their relatively high density and atomic number (Zeff). However, the current Ce:LuAG exhibit a light yield much lower than expected theoretical value inevitable presence of LuAl antisite defects at si...

The purpose of this study is to compare the marginal leakage of two aesthetic cervical restorative materials viz the newly introduced light cured nano glass ionomer cement and nano ceramic composites, and also to evaluate the effect of unfilled resin sealant coating on marginal leakage of these aesthetic restorations. Thirty freshly extracted human upper premolars were used for the study. Class...
