objectives : because of poor bond between resin cement and zirconia ceramics, laser surface treatments have been suggested to improve adhesion. the present study evaluated the effect of co 2 and nd:yag lasers on the shear bond strength (sbs) of resin cement to zirconia ceramic. materials and methods : ninety zirconia disks (6×2 mm) were randomly divided into six groups of 15. in the control gro...
IMPORTANCE Fractionated, ultrapulsed carbon dioxide (CO2) laser therapy is a powerful tool for the treatment of scars. Common adverse effects of this therapeutic modality have been previously documented. We describe 2 unreported adverse effects of ultrapulsed CO2 laser treatment of mature scars in a patient previously treated with silver-impregnated dressings. OBSERVATIONS A teenage survivor ...
Background and aims: Skin rejuvenation is one of high demand cosmetic interventions in Iran. Fractional CO2 Laser is a high power ablative laser which has variety of utilization in medicine including treatment of acne scars and rejuvenation. The aim of this study was to evaluate the safety, efficacy, and cost-effectiveness of Fractional CO2 Laser in comparison with other methods of rejuvenation...
In this study, we investigate the effects of CO2 laser polishing on microscopic structures fabricated by femtosecond laser assisted carving (FLAC). FLAC is the peripheral laser irradiation of 2.5D structures suitable for low repetition rate lasers and is first used to define the microwell structures in fused silica followed by chemical etching. Subsequently, the bottom surface of patterned micr...
