Fournier's Gangrene (FG) is an infectious disease caused by several synergic microbes, with high morbidity and mortality rates; therefore, the search for new less invasive and mutilating treatments, with faster recovery, has been proposed. Surgical intervention, the use of several systemic and topic antibiotics, and hyperbaric oxygen therapy are currently the best approach for the treatment of ...

A diode laser, which emitted infrared radiation at a wavelength of 810 nm, was used to perform trabecular photocoagulation in a human eye due for enucleation for malignant melanoma. For comparison, burns were applied with an argon blue-green laser (488-514.5 nm). With each laser, the treatment spot size was 100 microns and the pulse duration was 0.20 sec. Visible lesions were produced with a po...

introduction: the aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (naocl) as a common root canal irrigant in canals infected with enterococcus faecalis ( e. faecalis ). methods and materials: the root canals of 18 extracted single-rooted premolars were prepared by rotary system. after decoronation, the roots...

At NIST in Boulder we have been pursuing an active research program developkg diode-laser technology for scientific applications. Commercial diode lasers are readily available in a few wavelength bands in the red and near IR region of the spectrum. Om work has focused on the AIGaAs, InGaAlP, and InGaAsP lasers that operate at room temperature in the red and near IR region of the spectrum betwee...

Introduction The development of laser diodes has increased the variety of practical applications for lasers as light sources in analytical spectroscopy. Lasers are excellent radiation sources due to their monochromaticity, good beam focusing capabilities, and small line-widths but have traditionally been expensive and difficult to operate, limiting their applications to specialized fields. Beca...

Band-edge liquid crystal lasers are of interest for a number of applications including laser projection displays. Herein, we demonstrate simultaneous red-green-blue lasing from a single liquid crystal sample by creating a two-dimensional laser array fabricated from dye-doped chiral nematic liquid crystals. By forming a pitch gradient across the cell, and optically pumping the sample using a len...

THE EFFECT OF THE BLUE LIGHT DIODE LASER ON SHEAR-PEEL BOND STRENGTH OF ORTHODONTIC BRACKETS WITH VARYING CURING TIME AND DISTANCE Kamran Shaikh, DDS June 17,2010 Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in ha...
