laser irradiation has been suggested as an adjunct to traditional caries prevention methods. but little is known about the cariostatic effect of diode laser and most studies available are on permanent teeth.the purpose of the present study was to investigate the effect of diode laser irradiation combined with topical fluoride on enamel surface microhardness.forty-five primary teeth were used in...

introduction: laser-assisted vaporization of prostate tissue by means of the potassiumtitanyl- phosphate (ktp) laser is in clinical use. alternative laser sources are available but are lacking clinical experience.the 980 nm wavelength diode laser provides good hemostasis, in addition to a more rapid ablation rate. the aim of this study is approving the capability, feasibility, and good post-ope...

objectives: dental caries and periodontal diseases are caused by infection of teeth and supporting tissues due to complex aggregate of bacteria known as biofilm, firstly colonized by streptococci. the main purpose of this in vitro study was to evaluate the antimicrobial effects of toluidine blue o (tbo) and radachlorin® in combination with a diode laser on the viability of streptococcus mutans....

vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...

introduction: several treatment options have been introduced for removal of gingival hyperplasic lesions, but using diode lasers have many advantages such as less bleeding, time saving, better shaping, improved healing and less complication for the patients. case: a 15-year-old girl with multiple fibroma-like lesions in the oral cavity, who had a medical history of tuberous sclerosis, was selec...

the standards of endodontics have constantly been raised in the last 25 years by practitioners’ researches and their interest. most of the scientists believe the recent developments and the use of lasers as the most exciting achievement in endodontic treatment. nowadays, lasers are being used in endodontics to improve the prognosis of the root-filled teeth. the implement of suitable wavelengths...

background and aims. considering the importance of disinfecting dentin after cavity preparation and the possible effect of disinfection methods on induction of various reactions between the tooth structure and the adhesive restorative material, the aim of the present study was to evaluate microleakage of composite resin restorations after disinfecting the prepared dentin surface with nd:yag and...

abstract background: in recent years, the endovenous laser therapy (evlt) has been proposed to treat the incompetent greater saphenous veins (gsv) to increase patient comfort,and to reduce cost as well as risk. evlt causes vein wall thickening, luminal contraction and vein fibrosis. the purpose of this article, as the first report from iran, is to review our experience and outline the early res...

Introduction: The ultimate goal of endodontic treatment is to eliminate the bacterial infection in the root canal system. While mechanical debridement combined with chemical irrigation removes the bulk of microorganisms, residual bacteria are readily detectable in approximately one-half of teeth just prior to obturation. Laser light can be used to destroy bacteria. This in vitro study was perfo...
