introduction: this study aimed to assess the scanning electron microscope (sem) analysis of tooth surface irradiated by erbium:yttrium–aluminum–garnet (er:yag) laser with various parameters. methods: number of 25 extracted human third molars free of caries were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 0.5 w, energy: 50 mj); group 2 (...

PURPOSE The aim of this study is to compare the length of time from uneventful cataract surgery using one of two common posterior chamber intraocular lenses (IOLs) (hydrophilic versus hydrophobic acrylic) to laser capsulotomy. MATERIALS AND METHODS Retrospective analysis of all patients who underwent neodymium: yttrium-aluminum-garnet laser capsulotomy between 2011 and 2014 following uneventf...

Background: Laser surgery and radiotherapy are commonly used to treat glottic cancer. Objective of Review: To compare outcomes and cost of laser surgery versus radiotherapy for T1–T2N0 glottic cancer. Type of Review: Meta-analysis. Search Strategy: The Cochrane Central Register of Controlled Trials, Ovid MEDLINE In-Process & Other NonIndexed Citations, Embase, Web of Science (1990–2010) were se...

BACKGROUND Low-level laser therapy (LLLT) has been shown to modulate the inflammatory process without adverse effects , by reducing pain and swelling and promoting the repair of damaged tissues. Because pain, swelling and muscle spasm are complications found in virtually all patients following oral surgery for the removal of impacted teeth, this model has been widely used to evaluate the effect...

In the present work, a theoretical analysis of the first-order of stimulatedBrillouin scattering (SBS) in a double-clad (DC) ytterbium (Yb)-doped silica fiber laserin unidirectional pumping mode is presented.An accurate simulation for calculating SBS nonlinearity is performed by considering thecoupled differential rate equations for pump, signal and Stokes powers, as wel...

PURPOSE To report the anterior segment imaging characteristics after femtosecond laser assisted cataract surgery. METHODS Cataract surgery was performed with the LenSx femtosecond laser (Alcon-LenSx Inc., Aliso Viejo, CA) in 40 eyes of 40 patients. The laser was programmed to perform a 4.5-mm capsulorhexis, a cross-pattern fragmentation of the nucleus, a 2.8-mm main incision, and a 1.0-mm sid...

OBJECTIVES Since 1962 laser appliances have been used for soft tissues surgery of oral cavity with significant advantages compared to the traditional instruments: excellent bleeding control, possibility to avoid the use of suture, good patient compliance thanks to a decrease of intra- and post-operative discomfort and biostimulating effect. Unfortunately, the wavelengths so far used have been s...

introduction: our aim was to compare the cost effectiveness of holmium laser prostate enucleation (holep) versus trans-urethral resection of prostate. methods:  we searched all available databases for any controlled trials comparing holep and turp from january 2000 to february 2009. two independent reviewers studied and appraised the selected evidences. then, effectiveness and cost effectivenes...
