BACKGROUND: Photobiomodulation, also referred to as low-level laser therapy (LLLT), has been studied and used for (among other diseases) the promotion of hair regrowth. OBJECTIVE/MATERIALS AND METHODS/RESULTS: A clinical study was developed to define the physiologic effects that occur when the human hair follicle and surrounding tissue structures are exposed to laser light using a novel device that is fitted with an array of laser diode sources operating at 650 nm and placed inside a sports cap to promote discretion while in use...

REVIEW
Jianru Yi, Jiani Xiao, Hanshi Li, Yu Li, Xiaobing Li, Zhihe Zhao
This study was aimed to summarize published systematic reviews that assess the effects of adjunctive interventions on the acceleration of orthodontic tooth movement (OTM). Electronic and manual searches were performed up to Aug 2016. Systematic reviews investigating the impact of adjunctive techniques on the promotion of OTM were included. The methodological quality of the included reviews was evaluated using the AMSTAR scale. The quality of evidence for each intervention was assessed using GRADE. The Jadad decision algorithm was used to select a study to provide body evidence from discordant reviews on the same intervention...

OBJECTIVE AND BACKGROUND: Tinnitus is an apparent sound, perceived in the ear with no stimulus. It has been described as a sound originating from the brain. It affects 17% of the general population. Etiological factors for tinnitus include temporomandibular joint disorders (TMJ, TMD) and Costen's syndrome. The aim of treatment is to eliminate the tinnitus or at least decrease its apparent volume. MATERIALS AND METHODS: In total, 46 patients referred to our department with bilateral subjective tinnitus with TMDs were selected for this study...

OBJECTIVE AND BACKGROUND: The surgical removal of impacted third molars is one of the most common procedures performed by oral and maxillofacial surgeons. The purpose of this study is to determine whether either transcutaneous or intraoral low-level laser therapy (LLLT) reduces postoperative pain and assists in the healing of mandibular third molar extraction. MATERIALS AND METHODS: This randomized, placebo controlled, single-blind, split-mouth design study was conducted on 60 patients with full bony impacted similar position mandibular third molars bilaterally...

Reepithelialization and wound closure are the desired outcome for several ulcerative conditions. Such resolution reduces the possibility of wound contamination and maintenance of the injury and improves the reestablishment of tissue morphology and functions. Investigators are seeking adjuvant therapies that can accelerate wound healing and are developing new strategies for clinical applications. This study compared the effects of epidermal growth factor (EGF) application and low-level laser therapy (LLLT) on cultured epithelial cells...

In the present study, the changes that occur in rat liver tissue as a result of the use of grapeseed extract (GSE) and low level laser therapy (LLLT) in intraoral wound healing are analyzed using biochemical parameters. Diode laser application groups received 8 J/cm(2) dose LLLT once a day for 4 days (810 nm wavelength, continuous mode, 0.25 W, 9 sec.). As a result of the biological parameter analysis, it was determined that the oxidative damage caused by the intraoral wounds and recovery period on 7(th) and 14(th) days could be substantially removed with GSE applications that have antioxidant capacity especially in rat liver tissue...

[Purpose] The purpose of this study was to investigate the effects of radiofrequency (RF), electroacupuncture (EA), and low-level laser therapy (LLLT), which are used in physical therapies, on facial wrinkles and moisture. [Subjects and Methods] A total of 30 female participants aged 30-55 years participated in this study and the results will be used as a reference for further development of skin physical therapy. Thirty adult females were assigned to an LLLT (n=10), EA (n=10), or RF group (n=10). The intervention was performed in two 15-minute sessions per week for six weeks...

Low level laser therapy (LLLT) has been shown to stimulate bone cell metabolism but their impact on the matrix metalloproteinase (MMP) expression and activity is little explored. This study evaluated the influence of LLLT at two different wavelengths, red and infrared, on MC3T3-E1 preosteoblast viability, alkaline phosphatase (ALP) and MMP-2 and -9 activities. To accomplish this, MC3T3-E1 cells were irradiated with a punctual application of either red (660nm; InGaAIP active medium) or infrared (780nm; GaAlAs active medium) lasers both at a potency of 20mW, energy dose of 0...

The purpose of this study was to analyze the low-level laser therapy (LLLT) on metalloproteinase expression and the mechanical strength of skeletal muscle regeneration after peripheral nerve injury. Rats were subjected to crush injury of the right sciatic nerve, followed by LLLT (830 nm, 35, 70, 140, and 280 J/cm(2)) for 21 consecutive days. Functional gait analysis was performed at weekly intervals and the animals were sacrificed after the last evaluation at day 21 for collection of the gastrocnemius muscles, which were submitted to analysis of resistance, and the tibialis anterior, for evaluation of metalloproteinase-2 (MMP-2)...

OBJECTIVE: To assess if low-level laser therapy (LLLT) enhances the efficiency of orthodontic dental alignment. BACKGROUND: There is no evidence of the effect of LLLT on the orthodontic treatment time from randomized clinical trials. METHODS: Thirty-six subjects were included in this interventional pilot study and randomly assigned for treatment with fixed appliance and LLLT (test group) or with fixed appliance only (control group). A single monthly administration of LLLT was performed intraorally using a Diode laser (980 nm, 1 W, continuous wave, total energy density = 150 J/cm(2); Doctor Smile-Lambda Spa)...

This report examines the potential of low level laser therapy (LLLT) to alter brain cell function and neurometabolic pathways using red or near infrared (NIR) wavelengths transcranially for the prevention and treatment of cognitive impairment. Although laser therapy on human tissue has been used for a number of medical conditions since the late 1960s, it is only recently that several clinical studies have shown its value in raising neurometabolic energy levels that can improve cerebral hemodynamics and cognitive abilities in humans...

OBJECTIVE: Temporomandibular disorder (TMD) is a variety of clinical problems that originate from the area of the temporomandibular joint (TMJ), masticatory muscles, and surrounding tissues. There are different treatment options; however, there is no evidence that low level laser treatment (LLLT) will last about six months. The aim of this study was to determine the survival rate of treatment with red (660 nm) and infrared (790 nm) laser in cases of TMDs. METHODS: In 19 subjects, one side of the face (half face) was randomly selected to receive intervention, in a total of 116 sensitive points...

Low-level laser therapy (LLLT) has been targeted as a promising approach that can mitigate post-infarction cardiac remodeling. There is some interesting evidence showing that the beneficial role of the LLLT could persist long-term even after the end of the application, but it remains to be systematically evaluated. Therefore, the present study aimed to test the hypothesis that LLLT beneficial effects in the early post-infarction cardiac remodeling could remain in overt heart failure even with the disruption of irradiations...

BACKGROUND: Because of its long-lasting analgesic action, bupivacaine is an anesthetic used for peripheral nerve block and relief of postoperative pain. Muscle degeneration and neurotoxicity are its main limitations. There is strong evidence that low-level laser therapy (LLLT) assists in muscle and nerve repair. The authors evaluated the effects of a Gallium Arsenide laser (GaAs), on the regeneration of muscle fibers of the sternomastoid muscle and accessory nerve after injection of bupivacaine...
