introduction: the aim of the present study was to investigate the effects of srp assisted by the two clinical treatment methods of diode laser or chlorhexidine gel applications in comparison with srp alone. methods: eight patients with moderate to severe chronic periodontitis, each with at least three pockets 4–7 mm deep, were selected for this study. over 66 pockets were selected and randomly ...

objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...

introduction: to investigate the ultrastructural changes of dentin irradiated with 980-nm diode laser under different parameters and to observe the morphological alterations of odontoblasts and pulp tissue to determine the safety parameters of 980-nm diode laser in the treatment of dentin hypersensitivity (dh). methods: twenty extracted human third molars were selected to prepare dentin discs. ...

Aims: To assess and report the microhardness incidence in fissure system of human dental enamel next Er,Cr:YSGG laser Diode applications order to examine anti-cariogenic impact compare obtained results between two types. Materials Methods: Forty extracted impacted lower third molars teeth used experiment that should have an obvious occlusal fissure. Intact molar were collected, which free from ...

The principle of laser induced cell/spore lysis was explored in this project. E. coli K12 and B. subtilis spores were chosen as the target analytes. The lasers available for testing were of wavelength 980nm and 1480nm. As a proof of concept, a 2μl droplet of E. coli culture in nutrient broth was place on a hydrophobic surface. The tip of the laser fiber was placed directly above the droplet, an...

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 The aim of this study was to evaluate the effect of diode laser irradiation and bleaching materials on the dentinal tubule diameter after laser bleaching. MATERIAL AND METHODS The dentin discs of 40 extracted third molar were used in this experiment. Each disc surface was divided into two halves by grooving. Half of samples were laser bleached at different wavelengths with two diff...

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 ...
