introduction: the purpose of this study was to evaluate the antimicrobial photodynamic therapy (apdt) and low level laser therapy (lllt) on wound healing, pain intensity, swelling problems, halitosis and the postoperative usage of analgesics after surgical removal of lower third molars. methods: one hundred and fifty patients, randomly divided into three groups were selected (50 per each group)...

application of optical radiation such as laser and other short wavelength radiation for inactivation of many food-borne pathogen microorganisms in food industry (as major challenges in the food industry and so that many diseases are resulted from this food contamination) was known as a new technology. material and methods: effects of green continuous waves lasers on structural (using sds-page m...

In this study. Nd:YAG laser induced lipid peroxidation in spinal cord and the efficacy of alfa-tocoferol on this process were investigated. The study was performed on 36 adult guinea pigs divided imo three group s . The first group was the control group and only laminectomy was performed. In the second group. using a Nd:YAGlaser. foeal spinal cord trauma was induced and lipid peroxidation value...

introduction in this study, we describe the results of controlled synthesis and application of gold coated fe3o4/sio2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (spr) phenomena. materials and methods magnetite nano-particles (mnps) were prepared by means of co-precipitat...

introduction: dark or black coloured gingiva is an esthetic concern especially in subjects with high lip line or gummy smile. gingival depigmentation procedure is a type of perioplastic surgery where the gingival epithelium is excised with various techniques to lighten the colour of the gingiva. the aim of this study was to compare the clinical efficacy of gingival depigmentation procedure with...

This dissertation explores the use of an Airborne Laser Scanner (ALS) for various types of aircraft Terrain-Referenced Navigation (TRN) techniques. Using the methods explored, an ALS-based TERRain Aided Inertial Navigator (TERRAIN) was developed, flight tested, and shown capable of providing meter-level positioning accuracy in real-time. The ALS-based TRN techniques discussed are constrained to...

We report on the surface modification effects using allyl‐diglycol CR39 polymer induced by laser irradiation at 157 nm F2 laser (VUV) and 248 nm KrF laser. The motivation is to investigate the ablation effects on this polymer in optical waveguides application the ablation effects on this polymer in optical waveguides. Fabrication of waveguides has been observed using continuous wave (CW) at 244...
