Histologic evaluation of thermal damage produced on soft tissues by CO2, Er,Cr:YSGG and diode lasers.
OBJECTIVE The aim of this in vitro experimental study was to perform histological evaluation of the thermal effect produced on soft tissue irradiated with CO2, Er,Cr:YSGG or diode lasers. STUDY DESIGN Porcine oral mucosa samples were irradiated with Er,Cr:YSGG laser at 1 W with and without water / air spray, at 2 W with and without water / air spray, and at 4 W with water / air spray, with CO...
متن کاملInduction of angiogenesis after TMR: a comparison of holmium: YAG, CO2, and excimer lasers.
BACKGROUND Transmyocardial laser revascularization (TMR) is an emerging treatment for end-stage coronary artery disease. A variety of lasers are currently available to perform the procedure, although their relative efficacy is unknown. The purpose of this study was to compare changes in myocardial blood flow and function 6 months after TMR with holmium:yttrium-aluminum-garnet (holmium:YAG), car...
متن کاملEffects of Er: YAG, 980 nm and 810 nm Diode Lasers Irradiation on Biocompatibility of SLA Titanium Disks Using SaOs2 Cells Morphology
Objectives The use of lasers for the treatment of periimplant hard and soft tissues is now refmore than ever before. Achieving bone integrity. The aim of this study is to evaluate the effects of Er:YAG, 980 nm and 810 nm diode lasers irradiation on biocompatibility of SLA titanium disks by SaOs2 cells morphology. Methods In this in-vitro study sixty sterile titanium disks with SLA surface were...
متن کاملPassively Q-switched ceramic Nd3+:YAG/Cr4+:YAG lasers.
Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...
متن کاملXPS analysis of the dentin irradiated by Er: YAG laser.
The aim of this study was to investigate the effect of Er:YAG laser irradiation on human dentin surface using X-ray photoelectron spectroscopy (XPS). 10 human dentin disks were prepared from extracted human molars for XPS analysis. These specimens were divided into two groups of five: a control group and group that were irradiated by an Er:YAG laser beam (100 mJ, 1Hz). All specimens were analyz...
