Recording of individual identification information on dental prostheses using fluorescent material and ultraviolet light.

Light Spectrum of Compact Fluorescent Lamps in Iranian Market and Possibility of Hydroxyl Radical Production

Background and purpose: Despite growing use of energy-saving lamps or compact fluorescent lamps (CFLs), there are concerns about ultraviolet radiation in their output. In this study, the output of CFLs available in Iranian market in the range of infrared, visible, and ultraviolet were measured and the possibility of hydroxyl radical production by their radiation was evaluated. Materials and me...

Altering internal surface of putty impression material for better recording of tooth preparation margins

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

The effect of incoherent ultraviolet light on the renal capsule tissue using dynamic mechanical analysis and FTIR spectroscopy

مطالعه پرتوهای فرابنفش انتشار یافته از لامپ‏های فلورسنت فشرده متداول

Background and aims: Compact fluorescent lamps(CFLs) are low-pressure mercury vapor lamps, which are more useful than other light sources. Some studies reported the leakage of UV radiation from CFLs. The aim of this study was measuring of ultraviolet radiation from universal compact fluorescent lamps in Iran. Methods: In this study, measuring of UV radiation of 54 bulb compact fluorescent lamps...
