The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

Introduction: Residual oxygen-free radicals of bleaching agents before composite restorations can increase microleakage in enamel and dentin margins, and also various bleaching techniques are being developed using light sources. The present study was conducted to compare the effect of diode laser bleaching and LED activated bleaching on the microleakage of composite restorations. Materials & M...

Background: Numerous lasers are currently available for hair removal. Objective: To study the efficacy of a pulsed diode laser for removing unwanted hair. Patients and Methods: In this quasi-experimental clinical trial, 39 patients with unwanted hairs on chin referred to Novin-Didegan Laser Center in Tehran were treated with a diode laser system (Palomar, 810nm). Fluences ranging from 40 to 64 ...

Introduction: Skin cancer has been increased day by day, but it can be cured if it diagnosed early. After reviewing the scientific literature about 980 nm diode laser, and its multiple advantages on skin diseases. We studied in this paper the effectiveness of this type of laser on the progression of skin cancer among hamsters which were exposed to carcinogen on the bac...

In this research, tunability of a commercial diode laser has extended to about more than ± 11 nm using a V-shaped external-cavity fabricated around the laser. Although under normal condition it can be tuned up to about ± 4 nm just by changing its temperature and injection current. Such modified diode laser has then used in a difference-frequency generation (DFG) experimental setup as pump sourc...

introduction: the aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (pdt) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. methods: in this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. after conventional chemo mechanical preparation of root canals, microb...

introduction: laser dentistry is a one of the upcoming advanced treatment modality for oral mucosal lesions. diode laser is a soft tissue laser that has found much acceptance in all branches of dentistry. available compact size and feasibility has render diode laser an enhanced tool for today’s clinical practice. the aim of this study is to determine the efficacy and safety of diode laser for t...

introduction: thermal changes in laser assisted root canal therapy with the use of diode laser can predispose tooth structure to the fracture. this study evaluated the changes in flexural strength of dentin blocks after diode laser irradiations (810 nm). methods: a total of 60 dentinal blocks were prepared from freshly extracted teeth in three different thicknesses (300, 500 and 1000μm) and 20 ...

introduction: the purpose of this case report is to analyze the results of vestibuleplasty around an over-denture based on dental implants to determine the evidence on the effectiveness of laser-assisted surgery and soft tissue management in implant dentistry. case report: the patient in this case report was a 57 year- old male who was completely edentulous, with a mandibular over denture based...
