BACKGROUND AND OBJECTIVE Sebaceous gland hyperplasia may be treated by cryotherapy, cauterization, topical chemicals, or excision. The major disadvantage of these therapeutic strategies is a considerable risk of postoperative scarring or dyspigmentation. The pulsed dye laser may be an effective and safe alternative treatment option. STUDY DESIGN AND METHODS Our report presents two patients wi...

Introduction: Laser tissue soldering using albumin and indocyanine green dye (ICG) is an effective technique utilized in various surgical procedures. The purpose of this study was to perform laser soldering of rat skin under a feedback control system and compare the results with those obtained using standard sutures. Material and Methods: Skin incisions were made over eight rats’ dorsa, which w...

Laser photocoagulation of the feeder vessels of age-related macula degeneration-related choroidal neovascularization (CNV) membranes is a compelling treatment modality, one important reason being that the treatment site is removed from the fovea in cases of sub- or juxtafoveal CNV. To enhance the energy absorption in a target feeder vessel, an indocyanine green dye bolus is injected intravenous...

For most experimental applications where organic dye lasers are used as light sources, it is necessary to narrow the spectral output which is up to a few hundred Ängstroms wide. Spectral narrowing down to 0.5 — 1 Ä can be achieved by using a diffraction grating as one of the resonator mirrors a set of prisms2 or an interference filter inside the laser cavity3. Further reduction of the emission ...

INTRODUCTION Controversial results have been reported when organic acids, ultrasonic instruments and laser techniques were used to remove smear layer in endodontic treatments. The aim of this study was to evaluate the effect of removing debris and smear layer by Er,Cr:YSGG laser irradiation on the apical leakage of retrograde cavities. MATERIALS AND METHODS In this ex vivo study, 24 extracted...

PURPOSE To determine the most appropriate time for laser irradiation to produce selective occlusion of new corneal vessels by photodynamic therapy (PDT) with a new photosensitizer, ATX-S10(Na). METHODS The time course of the plasma levels of ATX-S10(Na) and the degree of dye accumulation in the corneal neovascularization after intravenous administration was determined in rabbit eyes. Plasma c...

PURPOSE Local antimicrobial therapy is a fundamental principle in the treatment of lesions of medication-related osteonecrosis of the jaw. Antimicrobial photodynamic therapy (aPDT) as a local application for the treatment of microbial infections has become more widely used in recent years. In the mouth, the bone surface is in constant contact with saliva and thus cannot be kept sterile, making ...
