Clinical application of lasers in periodontal surgery has continued to expand in the last decade; however, controversies remain regarding their use. This article will describe the clinical application of erbium: YAG lasers for periodontal surgery: flap operations, osseous surgery, and semi-lunar coronally repositioned flap procedures, and peri-implantitis treatment by laser will be discussed.
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...
The emission characteristics of debris from laser-produced tin plasma were investigated for an extreme ultraviolet lithography (EUV) light source. The ions and droplets emitted from tin plasma produced by a CO2 laser or an Nd: YAG laser were detected with Faraday cups and quartz crystal micro-balance (QCM) detectors, respectively. A higher ion kinetic energy and a lower droplet emission were ob...
Background and aims: Skin rejuvenation is one of high demand cosmetic interventions in Iran. Fractional CO2 Laser is a high power ablative laser which has variety of utilization in medicine including treatment of acne scars and rejuvenation. The aim of this study was to evaluate the safety, efficacy, and cost-effectiveness of Fractional CO2 Laser in comparison with other methods of rejuvenation...
Background and Aims: Indirect composites are designed to overcome the shortcomings of direct composites such as polymerization shrinkage and low degree of conversion. But, good adhesion of resin cements to indirect composites is still difficult. This research was designed to assess the effect of different powers of ErYAG laser compared with sandblasting. On the micro tensil bond strength of r...
Purpose: Comparison of astigmatic correction and visual acuity outcomes in patients implanted with toric intraocular lenses following cataract surgery reference marked pre-operatively manually with a pen or with YAG laser, in conjunction with the Sunalp YAG Laser Lens. Methods: 16 eyes from 16 patients were divided into two groups of 8 patients each. Pre-operativelly, the eye of one group was r...
