Soft Tissue Laser Surgery is different from Hard Tissue Laser Surgery (bones and teeth in dentistry) and Laser Eye Surgery (eye sight corrective surgeries) by particular types of lasers. Lasers differ from each other by the wavelength of light they produce. The most commonly used surgical laser in soft tissue surgery is the CO2 laser. The CO2 laser wavelength (10.6 micrometers) is highly absorb...

this study aimed to evaluate enamel roughness after adhesive removal using different burs and an er:yag laser.the buccal surfaces of forty human premolars were sealed by two layers of nail varnish, except for a circular area of 3 mm in diameter on the middle third. the enamel surfaces were initially subjected to profilometry analysis and four parameters of surface irregularity (ra, rq, rt and r...

purpose: to evaluate the effect of trans-scleral cyclophotocoagulation (tscpc) in reducing intraocular pressure in eyes with history of pars plana vitrectomy with or without intraocular silicone oil and refractory to medical treatment. methods: medical records of 35 eyes of 35 patients who underwent tscpc for medically uncontrolled glaucoma after pars plana vitrectomy for retinal pathology were...

Laser forming is a thermal forming process which uses laser beam irradiation to produce the desired final forms. In this article, the effect of temperature gradient across  Al 6061-T6 aluminum sheets on bending angle is studied. Input parameters including laser power, scan velocity, beam diameter, and sheet thickness are the effective process parameters which influence the temperature gradient....

one of the basic purposes in dental treatment is providing a painless treatment for patients. this purpose may be achieved by the application of laser in dentistry. low-level laser therapy (lllt) is an internationally accepted title for biomodulation with low-level lasers which we use to achieve ideal therapeutic effects. low-level laser therapy is a painless, reproducible, non-invasive, and wi...

introduction: periodontitis is an inflammatory disease, for which, scaling and root planning (srp) is the common approach for non-surgical control of inflammation. using lasers is another approach in the first phase of periodontal treatment for control of inflammation. diode laser has some beneficial effects such as acceleration of wound healing, promotion of angiogenesis and augmentation of gr...

PURPOSE To evaluate and compare the use of the Kowa laser flare cell meter and intravenous anterior chamber fluorophotometry in assessment of the blood-aqueous barrier after cataract surgery. METHOD Laser flare and cell measurements and fluorophotometry were performed at 1 and 3 months after surgery in 48 eyes of 44 patients admitted for routine cataract surgery. The fellow pseudophakic eyes ...
