introduction: smear layer (sl) is produced as a result of mechanical instrumentation of the canal(s). despite the controversies regarding its removal, the evidence-based trend has shifted towards removing and eliminating the sl. different methods have been used to remove the sl and the aim of this in vitro study was to evaluate the ability of 17% ethylenediaminetetraacetic acid (edta), 18% etid...

Introduction The Thulium fiber laser (TFL) is a new device that in contrast to the other solid-state YAG-based lasers takes different approach pulse formation allowing for two modes: QCW (quasi-continuous wave) function, TFL convenient soft tissue surgery and SP (Superpulsed) mode it highly effective lithotripsy. Thus, unlike thulium (Tm : YAG), can be used wide range of surgical procedures. Ma...

introduction: the aims of the present study were: [1] to evaluate whether erbium-doped: yttrium, aluminum and garnet (er: yag) laser could be a prophylactic methods against transient bacteremia during scaling and root planing (srp) [2] to confirm the efficacies of srp with er: yag laser by clinical and microbiologic evaluations. methods: twenty chronic periodontitis subjects were randomly treat...

A 38 year-old girl with a recurrent suppurative pilonidal cyst was successfully treated causally with an Nd-YAG laser, and with no recurrence at the 3-month follow-up. A similar success is observed for another 15 consecutively treated patients, including suppurative cases. The effect could be attributable to the ability of the YAG-laser to operate at a wave-length of 1064 nm and to penetrate th...

Laser trabeculotomies produced by directing a pulsed neodymium/YAG laser beam at specimens of human anterior chamber angle obtained post mortem or after enucleation were studied by light microscopy and by scanning and transmission electron microscopy to assess the dimensions of the openings created in the trabecular meshwork, their penetrance to the canal of Schlemm, and the extent or absence o...

Background: We evaluated endoscopic treatment of ureter stones with a holmium: yttrium-aluminum-garnet laser (Ho: YAG) lithotripter and an electrokinetic lithotripter (EKL) in children. Methods: Patients with ureteral stones, admitted to the pediatric surgery department of our hospital between November 2011 and January 2015, were evaluated retrospectively. Demographic data, initial symptoms, ag...

An unusual case of endobronchial Kaposi's sarcoma causing right middle and lower lobe atelectasis is reported. The lesion was successfully removed with Nd-YAG laser photoresection.

Background: Ablative laser treatment is widely used in dermatology. Different laser types are available. In contrast to that, the medical publication on erbium-YAG laser in dermatology often include small samples only. Objective: We want to demonstrate the versatility of classical erbium-YAG laser for medical conditions in dermatology in a single-center study. Materials and methods: This is a r...
