Microscopic Study on The Cutting Tissue with Hight Output Diode Laser and Erb: YAG Laser.

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

a comparative study of enamel surface roughness after bleaching with diode laser and nd: yag laser

introduction: bleaching process can affect surface roughness of enamel, which is a vital factor in esthetic and resistance of tooth. the aim of this study was to compare surface roughness of enamel in teeth bleached using diode and neodymium-doped yttrium aluminium garnet (nd: yag) lasers with those bleached using conventional method. methods: in this study, 75 anterior human teeth from upper a...

Make of Treatment Diode Laser with 670 nm and 5mw Output

بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته

هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...

Cutting and coagulation during intraoral soft tissue surgery using Er: YAG laser.

AIM To find the optimal techniques and parameters that enables Er:YAG laser to be used successfully for small intraoral soft tissue interventions, in respect to its cutting and coagulation abilities. CASE REPORT In vitro pre-tests: 4 different Er:YAG laser units and one CO2 unit as the control were used for incision and coagulation on porcine lower jaws and optimal parameters were established...
