AIM To evaluate chemically the effects of diode laser on fluoride uptake before and after laser irradiation of enamel surfaces. METHODS Crowns of 20 sound human teeth were halved and a 3 x 3 mm acid-resistant varnish uncovered window left for: A) no treatment; B) fluoride (Elmex gel); C) diode (fluoride + diode laser); D) diode (diode laser + fluoride). The dental surfaces were analysed using...

introduction: to determine efficacy of low level laser therapy for clicking temporomandibular joint (tmj) with a diode laser following orthodontic treatment. methods:  performance of lllt with a diode laser for temporomandibular clicking and postoperative findings were evaluated in a case of an orthodontic patient following the termination of treatment. patient had a history of severe clicking ...

peripheral ossifying fibroma is one of the commonest occurring reactive lesions on gingiva. it is associated with local irritational factors and often interferes with speech, mastication and maintenance of oral hygiene, in addition to being aesthetically unpleasant. it is usually treated with surgical excision using scalpel and removal of irritational factors, often resulting in mucogingival de...

Upconversion of 650 nm red light in Tml+ doped fluoride glasses results in the emission of blue light at 450 and 480 nm from the transitions (' D2 ->3 H4) and (' G4 ->3H6) respectively. The utilization of this effect in a blue upconversion fiber laser (UFL) device suited to high density optical recording (HOOR) has been the motivation for discussing various material properties and device parame...

The proposed thesis is to build a power build-up cavity pumped by a laser diode. In Raman spectroscopy there is a need for high power laser diode sources to be used in Raman gas monitoring applications. A high power laser source will allow the development of compact and low cost systems for use in any gas monitoring application where detection into the ppb is necessary. Gas detection can be acc...

INTRODUCTION Diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode was used as a possible instrument for soft tissue surgery in the oral cavity. DISCUSSION Diode laser is one of laser systems in which photons are produced by electric current with wavelengths of 810, 940 and 980nm. The application of diode laser in soft tissue oral surgery has been evaluated fr...

Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...

Introduction  Diode laser is a new alternative in stapes surgery for otosclerosis. The present study is the first to compare the short-term results of the surgery performed using diode laser to those obtained through the conventional fenestration technique. Objective  To use audiometry to establish a comparative analysis between the functional results obtained through surgery for otosclerosis u...

UNLABELLED Introduction The diode laser has been frequently used in the management of laryngeal disorders. The portability and functional diversity of this tool make it a reasonable alternative to conventional lasers. However, whether diode laser has been applied in transoral laser microsurgery, the ideal parameters, outcomes, and adverse effects remain unclear. Objective The main objective of ...
