The photodynamic therapy involves delivering visible light of the appropriate wavelength into a tissue or microorganism previously exposed to a photo-sensitive dye. Its use is widely spread between neoplastic and infeccious diseases. Nevertheless, its effects upon wound healing h...

The management of nonspecific lumbar pain (NSLP) using laser irradiation remains controversial. A systematic review of recently published studies indicates that the effects of laser therapy are commonly assessed using only imperfect methods in terms of measurement error. The main...

Abstract The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS). Thirty BMS subjects were randomized into two groups – Laser (LG) and Placebo (CG). Seven patients dropped out, leaving 13 patients in LG an...

Low intensity laser have been used currently as an alternative pain-relief therapy for muscle and joint pain since it induces analgesic, anti-inflammatory and biomodulation effects of the physiological cell functions. The purpose of this study was to evaluate the effect of GaAlAs...

Diabetic complications, including wound healing deficiency, are usually associated to chronic hyperglycemia, which leads to oxidative stress and aleatory protein glycation. The aim of this study was to evaluate the effects of high glucose concentrations (HGC) on proliferation, mi...

ABSTRACT Introduction: In dental practice, low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) are mainly used for dental surgery and biostimulation therapy. Within the Orthodontic specialty, while LLLT has been widely used to treat pain associated with orthod...

Low-intensity laser therapy (LILT) has been the subject of researches to understand the mechanisms by which the laser acts stimulating wound healing. This process is dependent of a signaling transfer between epithelium and connective tissue and it influences cellular proliferatio...

Oral mucositis is one of the most debilitating complications in patients undergoing bone marrow transplants, occurring 50 to100% in these patients. The oral mucositis treatment and prevention is not completely defined, although the low intensity laser is widely used. The aim of t...

Low-intensity lasers are used for prevention and management of oral mucositis induced by anticancer therapy, but the effectiveness of treatment depends on the genetic characteristics of affected cells. This study evaluated the survival and induction of filamentation of Escherichi...

Chronic inflammation has been associated with various stages of carcinogenesis, which have hitherto been studied with the aid of animal models. Low-power laser has also been investigated for its anti-inflammatory and proliferative potential. In order to establish a correlation be...

INTRODUCTION: Low-intensity laser (LILT) and LED therapy are indicated in repairing surgical incisions, which occur in cardiac surgery. One major concern in this case is the presence of metallic wire used for sternal sutures, its temperature may rise while using a laser or LED. T...

Vários estudos têm avaliado os efeitos do ultra-som e da radiação laser de baixa intensidade separadamente no reparo ósseo. No entanto, são escassas as comparações entre estas duas modalidades terapêuticas. Este estudo teve por objetivo avaliar e comparar, através de análise hist...

Este estudo investigou os efeitos do laser de baixa intensidade na velocidade da movimentação ortodôntica de caninos submetidos à retração inicial. A amostra constou de 26 caninos superiores e inferiores, submetidos à retração inicial realizada com mola Niti, com força de 150g. U...

Low-level laser therapy is an important method for the treatment of healing processes, and several experimental studies have been carried out in search of a greater understanding of its therapeutic possibilities. The objective of this study was to review pathogenetic aspects of s...

Fractures of delayed consolidation and fractures with non-union are commonly found in medical practice and are associated with high morbidity and mortality. Within this context, biochemical and biophysical resource have been studied in an attempt enhance bone healing. Among these...

Low level laser therapy (LLLT) is a therapeutic strategy in which its effects are still in a continuous process of evolution. The aim of the present study was to identify the effects of LLLT Ga-Al-In-P 660nm on the dynamics of a granulomatous inflammatory process in male swiss al...

Abstract: The article discusses the results of a literature review on the application of low intensity laser therapy on the healing of wounds associated diabetes mellitus in the last 10 years. Objective: To determine the most effective parameter in healing wounds related to diab...

The use of low-intensity laser and Light-Emitting Diode (LED) on the behavior of fibroblasts and in reducing the incidence of oral mucositis in children under chemotherapy were evaluated. The study was performed in two separate experiments. In the first moment, the viability of f...

This study aimed to evaluate histometrically the influence of a calcium phosphate cement and a low intensity laser on bone repair around titanium implants placed in rabbit tibiae. Twelve adult rabbits were used, and two bone defects of 3.7 mm diameter were prepared in each tibia....

Laser is one of the most effective resources of treatment for tendinous injury when anti-inflammatory and cicatrizing effects are wanted. However, it is considered an expensive treatment and so, an alternative and cheaper light therapy as effective as it has been searched and the...
