BACKGROUND AND OBJECTIVES A reliable method to eradicate the bacteria of residual carious dentin has not yet been developed. The aim of this study was to evaluate the antibacterial effect of a diode laser on Streptococcus mutans through different thickness (500, 1,000, and 2,000 microm) of human dentin. The thermal effect of laser irradiation was also investigated. STUDY DESIGN/MATERIALS AND ...

Background and aims: This study aimed to evaluate the efficacy of ibuprofen, bite wafer and low power red and infrared lasers in orthodontic pain management. Subjects and methods: One hundred subjects were randomly assigned to 5 groups of 20 each. The patients in each group received one of the following treatments after the placement of fixed orthodontic appliances: 1. placebo medication, 2. ib...

Effects of low-power laser irradiation on cell locomotion in protozoa. Photochem Photobiol. 2004; 80 (3):531-534. Low-power lasers are commonly used in human medicine for treatment of various pathological conditions, but mechanisms of their healing effects are still poorly understood. The results of this study provide information related to these effects at the cellular level. Two different pro...

The bactericidal effect of hydroxyl radical (·OH) generated by combination of photolysis of hydrogen peroxide (H2O2) and sonolysis of water was examined under the condition in which the yield of ·OH increased additively when H2O2 aqueous solution was concomitantly irradiated with laser and ultrasound. The suspension of Staphylococcus aureus mixed with the different concentrations of H2O2 was ir...

introduction: dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. the purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity. methods: in this pil...

BACKGROUND Various trials have been conducted on the management of male pattern hair loss (MPHL). A variety of laser and light sources have been used for the treatment of MPHL. OBJECTIVE To understand the effects of a 1,550-nm fractional erbium-glass laser on the hair cycle in an alopecia mouse model and to study the clinical effects of the same laser used as treatment for MPHL. MATERIALS A...

Since 1991, phototherapy (low-level laser therapy, near-infrared ray therapy and light-emitting diode: LED therapy) has been used in the management and rehabilitation of patients with various orthopaedic diseases. The laser used was a gallium aluminum arsenide (GaAlAs) diode laser giving output powers in continuous wave of 100 mW, at a wavelength of 810 nm. The target points were the acupunctur...

The author would like to insert the citation after the following sentence, "These RBPs are detected on laser trackswithin one minute after laser irradiation, and are excluded from the laser tracks shortly (within 10-15 min, depending on conditions of laser irradiation) [1]", in the paper published in the International Journal of Molecular Sciences [2].[...].
