used in conjunction with or as a replacement for traditional methods, it is expected that specific laser technologies will become an essential component of contemporary dental practice over the next decade. the current review is designed to focus on the acid resistance of laser application and tries to introduce laser settings capable to achieve this feature for clinical application. applicatio...

background: genital warts are the most common viral sexually transmitted disease affecting 1% of the population. a prospective, open-label controlled trial was performed to compare topical 5% potassium hydroxide (koh) solution with co2 laser in the treatment of female genital warts. methods: seventy patients were enrolled in the study after convenience sampling. right-sided lesions of the patie...

ftr-raman spectra of human dental enamel, both laser-irradiated and untreated, are reported. spectra are compared with hydroxyapatite. it is evident that unlike the co2 laser, the nd/yag laser does not induce any chemical change in dental enamel.

introduction: mucous retention cysts are a subtype of intracordal vocal cysts that may occur spontaneously or may be associated with poor vocal hygiene, and which require optimal treatment. the objective of this study was to present a new laser-assisted microsurgery technique for treating intracordal mucous retention cysts and to describe the final outcomes.   materials and methods: in this pro...

the aim of this study was to assess the surface of yttrium-stabilized tetragonal zirconia (y-tzp) after surface treatment with lasers and airborne-particle abrasion.first, 77 samples of presintered zirconia blocks measuring 10 × 10 × 2 mm were made, sintered and polished. then, they were randomly divided into 11 groups (n=7) and received surface treatments namely, er:yag laser irradiation with ...

BACKGROUND Low-level laser therapy (LLLT) with various types of lasers promotes fibroblast proliferation and migration during the process of wound healing. Although LLLT with a carbon dioxide (CO2) laser was also reported to promote wound healing, the underlying mechanisms at the cellular level have not been previously described. Herein, we investigated the effect of LLLT with a CO2 laser on fi...

The emission characteristics of debris from laser-produced tin plasma were investigated for an extreme ultraviolet lithography (EUV) light source. The ions and droplets emitted from tin plasma produced by a CO2 laser or an Nd: YAG laser were detected with Faraday cups and quartz crystal micro-balance (QCM) detectors, respectively. A higher ion kinetic energy and a lower droplet emission were ob...
