14. The influence of low-level laser irradiation on spinal cord injuries following ischemia- reperfusion in rats
PURPOSE:To investigate if low level laser therapy (LLLT) can decrease spinal cord injuries after temporary induced spinal cord ischemia-reperfusion in rats because of its anti-inflammatory effects.METHODS: Forty eight rats were randomized into two study groups of 24 rats each. In group I, ischemic-reperfusion (I-R) injury was induced without any treatment. G

15. Low-level red laser therapy alters effects of ultraviolet C radiation on Escherichia coli cells
Low-level lasers are used at low power densities and doses according to clinical protocols supplied with laser devices or based on professional practice. Although use of these lasers is increasing in many countries, the molecular mechanisms involved in effects of low-level lasers, mainly on DNA, are controversial. In this study, we evaluated the effects of l

16. Use of low-power laser to assist the healing of traumatic wounds in rats
PURPOSE: To investigate the morphological aspects of the healing of traumatic wounds in rats using low-power laser.METHODS:Twenty four non isogenic, young adult male Wistar rats (Rattus norvegicus) weighing between 200 and 300g was used. The animals were randomly distributed into two groups: Control (GC) and Laser (GL), with 12 animals each. After shaving, a

17. Effects of low-power light therapy on wound healing: LASER x LED
Several studies demonstrate the benefits of low-power light therapy on wound healing. However, the use of LED as a therapeutic resource remains controversial. There are questions regarding the equality or not of biological effects promoted by LED and LASER. One objective of this review was to determine the biological effects that support the use of LED on wo

18. In Vitro antimicrobial photoinactivation with methylene blue in different microorganisms
AIM: To evaluate the in vitro antimicrobial effects of photodynamic therapy (PDT). METHODS: The microorganism indicators were: Candida albicans, Pseudomonas aeruginosa,Enterococcus faecalis and Staphylococcus aureus. A microbial pool was prepared (10 8 cells/mL), from which aliquots were transferred to culture plates for carrying out the PDT using methy

21. Photodynamic therapy associated with full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis: a randomized-controlled clinical trial
Background: Photodynamic therapy (PDT) is a method of microbial reduction which can benefit periodontal treatment in areas of difficult access, such as deep pockets and furcations. The aim of this randomized controlled clinical trial was to evaluate the effects of PDT as an adjunct to full-mouth ultrasonic debridement in the treatment of severe chronic per

22. Efeitos dos lasers de diodo de alta e baixa potência no processo de reparo de reabsorções radiculares após reimplante tardio: análise clínica e radiográfica em ratos / Effects of high and low diode power lasers in process of heal of root resorptions in delayed replanted: clinical and radiographic analysis in rats
Objetivo: Avaliar clínica e radiograficamente os efeitos da irradiação com laser de diodo de alta potência e de baixa potência em dentes de ratos, reimplantados tardiamente. Método: Foram utilizados incisivos direitos de cinquenta ratos (Wistar) com peso entre 250 a 350g. Os dentes foram extraídos, permanecendo em meio ambiente durante 60min. Em segui

23. Estudo comparativo do efeito das fototerapias LED e LASER de baixa intensidade no tratamento da mucosite oral em pacientes submetidos à quimioterapia / Comparative study of the effects of LASER and LED phototherapies in the treatment of oral mucositis in patients submitted to chemotherapy
Patients submitted to chemotherapy and/or head and neck radiotherapy are usually affected by oral complications, especially oral mucositis and severe pain, which demands support therapy. Although the management of such oral complications by phototherapy with LASER (Laser Phototherapy - LPT) and with LEDs has been studied, the comparison between these therapi

24. Terapia laser de baixa intensidade a 808 nm reduz a resposta inflamatória e favorece a regeneração muscular
Muscle regeneration is a complex phenomenon, involving coordinated activation of several cellular responses. During this process, oxidative stress, and consequent tissue damage occur with a severity that may depend on the intensity and duration of the inflammatory response. Among the therapeutic approaches to attenuate inflammation and increase tissue repair
