introduction: the aim of this study was to evaluate and compare microhybride composite treated by bur and different power of erbium, chromium doped yttrium scandium gallium garnet (er,cr:ysgg) laser by scanning electron microscope (sem). methods: 21 microhybride composite blocks (diafil tm, diadent, korea) with 2 × 4 × 4 mm dimensions were made. the bonding surface of these blocks were polished...

Objectives: Carpal tunnel syndrome (CTS) is a common peripheral entrapment neuropathy with squeezing of the median nerve and the patient is unable to function properly. There are different physiotherapy interventions for the management of these patients and recently, shock wave therapy and low-power laser (LPL) have been widely used, but there is no strong evidence comparing the effect of shock...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...

introduction: the aim of this study was to investigate the scanning electron microscope (sem) analysis of tooth surface irradiated by different parameters of er:yag laser. methods: 15 caries-free extracted human third molars were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 2.5 w, energy: 250 mj); group 2(power: 3 w, energy: 300 mj); gro...

introduction: the use of lasers for treatment has become a common phenomenon in the medical field. currently, numerous laser systems are available for dental use. the use of lasers for periodontal treatment becomes more complicated because the periodontium consists of both hard and soft tissues. methods: related articles were gathered and selected carefully and reviewed. among the many lasers a...

in order to achieve a long-lasting effect, one of the main goals in root canal treatment is to eliminate the endodontic bacteria. conventional chemomechanical debridement is considered as the basic treatment in root canal therapy, but adjunctive techniques such as antimicrobial photodynamic therapy (apdt) can also be helpful. the aim of this study was to evaluate reports in the scientific liter...

one of the basic purposes in dental treatment is providing a painless treatment for patients. this purpose may be achieved by the application of laser in dentistry. low-level laser therapy (lllt) is an internationally accepted title for biomodulation with low-level lasers which we use to achieve ideal therapeutic effects. low-level laser therapy is a painless, reproducible, non-invasive, and wi...

the desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infection...

Background: Hirsutism is defined as the presence of terminalhairs with a male-like pattern in women, due to the increasedlevels of androgens or increased responses of the target organs toandrogens. Facial hirsutism has a negative effect on the quality oflife in female patients. Among the many therapeutic modalitie...

Lymphoedema and Laser Therapy Clinic, Adelaide, South Australia and a current director of the Australasian Lymphology Association Laser is amplified electromagnetic radiation in a particular wavelength range (measured in nanometres [nm]) produced by electronically stimulating a medium to release photon bundles of energy. Medical lasers can be broadly generalised into: 8 High output lasers that ...
