introduction: laser irradiation has been introduced in endodontic treatment due to its bactericidal effect. the aim of this study is to evaluate the bactericidal efficacy of a 940 nm diode laser alone or in combination with 5% sodium hypochlorite (naocl) against mature biofilms of e. faecalis . methods: sixty-eight (60 for the three groups, 4 for sem and 4 as negative controls) single-rooted hu...

plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. anthocyanin is affected by a variety of factors. light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. here, we have investigated the influence of the blue laser-diode (bld) and red laser-he ne (...

the minimal invasive nature of lasers, with quick tissue response and healing has made them a very attractive technology in various fields of dentistry which serves as a tool to create a better result than ever before. the rapid development of lasers and their wavelengths with variety of applications on soft and hard tissues may continue to have major impact on the scope and practice in prosthe...

introduction: the role of laser in conservative management of oral disease is well established. laser procedures are common in the fields of oral surgery, implant dentistry, endodontic, and periodontic therapy. case: this case series describes the use of diode laser for the excision of oral exophytic lesions. all the patients attended the oral medicine department of shahid beheshti university o...

introduction: pyogenic granuloma (pg) is one of the inflammatory hyperplasia seen in the oral cavity. it is a reactional response to minor trauma or chronic irritation. the most common treatment of pg is surgical excision but alternative approaches such as laser excision have also been proposed especially for pediatric patients. case report: herein, we present a case of gingival pyogenic granul...

High-power laser-diode arrays, which are made of stacks of individual or multistripe laser diodes, or in some cases vertical-cavity surfaceemitting lasers (VCSELs), can put out watts to kilowatts of optical power for uses such as laser pumping, industrial heating, illumination, or as the input for fiber-optic direct-diode laser devices for materials processing or for medicine. Laser diodes typi...

BACKGROUND Alexandrite (755 nm) and diode lasers (800-810 nm) are commonly used for hair removal. The alexandrite laser technology is somewhat cumbersome whereas new diode lasers are more robust. Recently, alexandrite-like 755 nm wavelength diodes became available. OBJECTIVES To compare the efficacy, tolerability, and subject satisfaction of a 755 nm diode laser operated in conventional (HR) ...

Volume Bragg gratingTM (VBGTM) technology has been shown to improve spectral characteristics of the high-power laser diodes and arrays. We review the recent advances in VBG technology that lead to better spectral performance as well as improvements in spatial brightness of the high-power laser diode arrays. The VBG technology has been applied to manufacturing of high-power laser diode arrays su...

The change is driven by the recent advances in diode laser technology and diode laser frequency conversion techniques, which now push the limits of emission wavelength...

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...
