An excitation migration over the level 411~/2 was studied in Cr:Er:YSGG laser crystal using an upconversion nonholographic light induced grating (LIG) technique. A long distance of migration ( = 1 /zm) was found. The diffusion coefficient was determined to be equal to 7 Γ 10 -7 cm2/s. This value was
## Abstract ## Background and Objective Erbium lasers are potential tools to remove caries and dental hard tissue but bond strengths of composites to those preparations are reported to be lower than conventional methods. The purpose of this study was to evaluate the effect of mechanical excavation
## Abstract ## Background and Objective If there is insufficient bonding to the enamel, the shrinkage of composites that occurs during polymerization can result in a gap between the filling material and the cavity wall. This gap permits the passage of bacteria or their metabolic products and also
