Three cases of malignant glaucoma following extracapsular cataract extraction with 7 mm one-piece posterior chamber intraocular lens implantation are presented. Nd-YAG laser hyaloidotomy was successfully performed in all eyes, but was difficult and required several sessions in two eyes. In the third eye, which had a sector iridectomy, laser hyaloidotomy applied over the edge of the lens optic t...

In our study we tested the efficacy of disinfection with diode laser Nd : YAG root canals of single-rooted teeth and lesion models of different sizes (6, 10 and 14 mm), in which we put the teeth and made an in vitro model. Teeth and models we re-infected with S. mitis as one of the most common microbes for re-infection, till the growth of the biofilm. The growth of the biofilm was confirmed mic...

Objective: To evaluate therapy effects and capability to preserve adjacent tissues of bilateral focal prostate ablation using Nd: YAG laser a canine model. Methods: 24 male Beagle dogs aged 3.9-7.4 years and weighting 9.4-12.1 kg were used in this study. The dogs underwent single focal Nd: YAG ablation. Applied the reasonable prostatic ablation parameters screened in the study and set different...

In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributio...

background: dental surfaces prepared with different er:yag laser distance may have different characteristics compared with those prepared with conventional instruments. the aim of this study was to investigate the effect of er:yag laser irradiation distance from enamel and dentin surfaces on the shear bond strength of composite with self-etch and etch and rinse bonding systems compared with con...

Nowadays, Erbium: YAG laser resurfacing of periorbital skin has become a very popular method of wrinkle reduction. Seven patients with Fitzpatrick skin phototypes of II to V were treated with a 2940 nm Erbium: YAG laser system for resurfacing of periorbital wrinkles. Photographic evalution performed before and after treatment. Patients were visited at 1,2,3,5,7,14,30 and 60 days after laser res...

Background and Aims: Restoration of non-carious cervical lesions (NCCLs) is challenging due to the difficulty of adhesion of dental tissues. The aim of this study was to investigate the effects of three methods of surface treatments using diamond bur, Er: YAG laser and sandblasting on the microtensile bond strength of resin composite to the noncarious dentin in cervical lesions. Materials and ...

Endoscopic management of ureteral calculi is one of the most important therapies in academic centers. Amongst these Laser and Pneumatic Lithotriptors are gaining popularity. This study was designed to study the efficacy and outcomes of both the available Lithotriptors. 200 patients presenting to the Urology OPD in our tertiary center were divided into 2 groups; first group being treated with pn...
