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...

FTR-Raman Spectra of human dental enamel, both laser-irradiated and untreated, are reported. Spectra are compared with hydroxyapatite. It is evident that unlike the CO2 laser, the Nd/YAG laser does not induce any chemical change in dental enamel.

introduction: laser surgery as an alternative for conventional surgical procedure has gained special attention. using carbon dioxide (co2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. case report: a 12 years old boy with lingual frenum with indication for excision was r...

statement of problem: the achievement of a good and durable dentin/composite resin bond is an important task in restorative dentistry. the application of acid conditioners and dentin bonding agents is an accepted method to enhance this bond strength. pretreating of dentin surface by laser irradiation seems to be a supplemental way to obtain better results, since lased dentin is more roughened a...

introduction: dentine hypersensitivity (dh) is characterized by a short sharp pain arising from the exposed dentine, in response to a thermal, evaporative, tactile, osmotic or chemical stimulus. the aim of this study was to evaluate the efficacy of nd:yag laser therapy and desensitizing gel (sensikin®, laboratorios kin s.a., barcelona, spain) in treatment of dentine hypersensitivity. methods: a...

Radiotherapy plays an important role in the treatment of hepatocellular carcinoma (HCC). Cyclin G1 is a novel member cyclin family, and it abnormally expressed HCC. In this study we investigated radiotherapy HCC cells. The expression was silenced by transfection G1-siRNA into HepG2 cells Huh7 cells, mRNA protein measured qRT-PCR Western blot analysis. proliferation analyzed using MTT assay, rad...

Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...
