Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...
Background and Aim: Warts are benign tumors caused by different types of human papillomavirus. Different methods are used in the treatment of warts. The aim of this study was to compare the effectiveness, side effects and number of treatment sessions of CO2 laser and cryotherapy in the treatment of plantar warts Methods: Seventy patients (140 feet) with plantar warts on both feet who referre...
Background and Aim: Melasma is a common disease affecting quality of life. Available treatments result in the gradual and partial clearance of melasma, and are accompanied with high risk of recurrence after discontinuing treatment. Tranexamic acid has been successfully evaluated in several studies. In addition, laser has been proposed as an enhanced drug delivery method. This study is designed ...
Pulse Dye Laser (PDL) is mainly used to treat vascular lesions but several studies performed in different research centers have shown the efficacy of this safe laser in the treatment of non-vascular lesions as well. The aim of this study was to review, sum up and summarize these studies.PDL is a known alternative for cryotherapy in the treatment of some viral lesions such as periungual warts an...
Introduction: Photothermal therapy using gold nanoshells is one of cancer therapy methods. Gold nanoshells generally consist of a silica core and a thin gold shell. Fe3O4@Au core-shell can be used for magnetic targeted therapy. The objective of this study was investigation of the photothermal effects of magnetically targeted Fe3O4@Au NPs and NIR laser irradiation on model of me...
dentin hypersensitivity (dh) is a relatively common painful condition among dental problems. although many studies have been performed regarding the diagnosis and treatment of dh, dental practitioners are still confused about the definite diagnosis and treatment.the use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985. laser treatment in dentin hypersensitivity ...
introduction :the aim of this study was to evaluate and compare the in vitro effect of the erbium-doped yttrium aluminum garnet (er:yag) laser with different radiation distances and high-speed rotary treatment on the shear bond strength of flowable composite to enamel of human permanent posterior teeth . methods : freshly extracted human molar teeth with no caries or other surface defects were ...
Background: Nevus spilus can produce considerable disfigurement. There is no specific and successful treatment for this nevus. Objective: The purpose of this study was to evaluate the efficacy of CO2 laser in the treatment of nevus spilus. Patients and Methods: This quasi-experimental clinical trial was performed on 47 patients with spilus nevus in Al-Zahra Hospital in Isfahan. The diagnosis of...
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...
