[Purpose] Temporomandibular joint (TMJ) pain is a symptom of TMJ disease. Low-level laser therapy (LLLT) is often used in the clinical treatment of TMJ pain. The aim of this study was to review the effective parameters of LLLT for TMJ pain. [Methods] This study was a systematic review in which electronic databases were searched for the period of January 2005 to January 2010. We selected reports...

BACKGROUND Keloids are characterized by excessive collagen deposition in the dermis, in which transforming growth factor β (TGF-β)/Smad signaling plays an important role. Low-level light therapy (LLLT) is reported as effective in preventing keloids in clinical reports, recently. To date, studies investigating the effect of LLLT on keloid fibroblasts are extremely rare. OBJECTIVE We investigat...

OBJECTIVE To evaluate the effects of low-level laser therapy (LLLT) on acute, full-thickness wound healing in dogs. STUDY DESIGN Randomized block (dog); historical control. ANIMALS Adult male Beagles (n = 10). METHODS Two 2 × 2 cm(2) wounds were surgically created bilaterally on the trunk of each dog. Each side was randomized to receive LLLT (laser, LAS) or standard-of-care management (co...

Low level light therapy (LLLT) has numerous therapeutic benefits, including improving wound healing, but the precise mechanisms involved are not well established; in particular, the underlying role of cytochrome C oxidase (C-ox) as the primary photoacceptor and the associated biochemical mechanisms still require further investigation. We previously showed the nitric oxide (NO) donating drug nit...

SUMMARY OBJECTIVES This study evaluated the effect of low-level laser therapy (LLLT) on the tendency of rat molars to relapse following orthodontic tooth movement (OTM). MATERIAL AND METHODS Maxillary rat molars were moved mesially for 10 days. Animals were randomly assigned to group I (non-irradiated) or II (irradiation with LLLT). Appliances were removed, and the molars allowed to relapse f...

BACKGROUND AND PURPOSE Low-level laser therapy (LLLT) is proposed as a treatment for tendinopathies. This is the first systematic review focusing solely on LLLT treatment effects in shoulder tendinopathy. METHODS A systematic review with meta-analysis and primary outcome measures pain relief on 100-mm visual analogue scale (VAS) and relative risk for global improvement. Two independent assess...

BACKGROUND/AIM Low-level laser therapy (LLLT) has been proven to stimulate bone repair, affecting cellular proliferation, differentiation and adhesion, and has shown a potential to reduce the healing time following implant placement. The aim of this clinical study was to investigate the influence of postoperative LLLT osseointegration and early success of self-tapping implants placed into low-d...

Background: A systematic review on low-level light/laser therapy (LLLT) in male pattern hair loss (MPHL) and female (FPHL) has been performed. Objectives: Compare the reported effectiveness of LLLT MPHL FPHL with any control, through randomized controlled trials (RCTs) analysis. Methods: The protocol was developed accordance Preferred Reporting for Items Systematic Reviews Meta-Analyses-Protoco...

The aim of this study was to evaluate the effect of specific parameters of low-level laser therapy (LLLT) on biofilms formed by Streptococcus mutans, Candida albicans or an association of both species. Single and dual-species biofilms--SSB and DSB--were exposed to laser doses of 5, 10 or 20 J/cm(2) from a near infrared InGaAsP diode laser prototype (LASERTable; 780 ± 3 nm, 0.04 W). After irradi...

BACKGROUND Low-level laser therapy (LLLT) has been demonstrated to be effective in optimizing skeletal muscle performance in animal experiments and in clinical trials. However, little is known about the effects of LLLT on muscle recovery after endurance training. OBJECTIVE This study evaluates the effects of low-level laser therapy (LLLT) applied after an endurance training protocol on bioche...
