Objective : The aim of this study was to observe and evaluate the micro-morphology of enamel and dentin surfaces after Er:YAG laser preparation and conditioning. Background Data : Information regarding micro-morphologic changes of tooth substance as a result of a change of Er:YAG laser parameters...
Objective : Bacteriochlorophyll- a (BChl- a ) was incorporated into nanoparticles of poly(D,L-lactide-co-glycolide) (PLGA), in order to evaluate this photosensitizer when associated with this specific drug delivery system (DDS) to analyze its physical and spectral properties. Background Data : It...
Objective : The purpose of this study was to evaluate the hypothesis that conditioning with Er,Cr:YSGG laser energy would affect bond strength of glass ionomers to dentin. Methods : Forty extracted caries-free human premolars were selected and ground to expose occlusal dentin. Then the teeth were...
Objective : The authors conducted this pilot study to prospectively investigate the effectiveness of low-power laser irradiation (780 nm) in the treatment of patients suffering from incomplete peripheral nerve and brachial plexus injuries for 6 months up to several years. Background Data : Injury...
Objectives : This study was designed to determine the optimal treatment frequency with the 308-nm excimer laser for vitiligo and identify key clinical variable(s) associated with treatment efficacy at the optimal frequency. Background Data : Optimal clinical parameters for excimer laser treatment...
