introduction: pyogenic granuloma (pg) is one of the inflammatory hyperplasia seen in the oral cavity. it is a reactional response to minor trauma or chronic irritation. the most common treatment of pg is surgical excision but alternative approaches such as laser excision have also been proposed especially for pediatric patients. case report: herein, we present a case of gingival pyogenic granul...

introduction: the aim of this study was to evaluate and compare the scanning electron microscope (sem) of indirect composite conditioned by erbium-doped yttrium aluminum garnet (er:yag) laser, neodymium-doped yttrium aluminium garnet (nd:yag) laserand carbon dioxide (co2) laser. methods: 18 indirect composite blocks (gc gradia da2, japan) with 15 × 10 × 10 mm dimensions were made. the bonding s...

In this work, potential of the nanosecond laser processing technique on manipulating the surface wettability of 316L bio grade stainless steel is investigated. Results show that the steel wettability toward water, improves significantly after the laser treatment. Different analyses are assessed in correlation with wettability using Scanning Electron Microscope (SEM), Scanning Tunneling Microsco...

Rhinophyma is a severe late complication of rosacea, which is characterized by progressive hyperplasia of sebaceous glands and connective tissue involving the lower two-thirds of the nose. It can be an emotionally devastating disorder, and serve as a medium for occult cancers and other health problems. Many surgical treatments have been advocated, as well as dermabrasion and laser therapy. In l...

treatment protocols with low-level laser (also called ‘soft laser therapy) have been used in health care systems for more than three decades. bearing in mind the suitable sub-cellular absorption and the cellular-vascular impacts, low-level laser may be a treatment of choice for soft tissues. low-level lasers have played crucial and colorful roles in performing periodontal surgeries. their anti-...

o bjectives: providing reliable attachment between bracket base and zirconia surface is a prerequisite for exertion of orthodontic force. the purpose of the present study was to eval- uate the effect of four zirconium surface treatment methods on shear bond strength (sbs) of orthodontic brackets. mat erials and methods: one block of zirconium was trimmed into four zirconium sur- faces, which se...

low-power lasers are a group of lasers with a power less than 500 mw and unlike high-power lasers they have no effect on tissue temperature; they produce light-dependent chemical reactions in tissues. the purpose of this study was to review the clinical applications of these lasers and their success rate in different studies in orofacial pains. the articles with the key word “low level laser th...
