Low-power, soft, or low-level laser irradiation has been successfully used to provide
analgesia in injured or diseased tissues. In this study, we tested the possible antinociceptive …

The present experiments sought to establish dose dependency and time course for effects of
cranial laser irradiation in two rodent models of pain. These were the hot plate and tail flick …

Laser irradiation of the rat cranium can produce analgesia. The present experiment
investigated the mechanism of such action. 27 rats received all possible combinations of …

The aim of the study was to confirm the analgesic effect of low-power laser radiation with a
tail-immersion test and check if nitric oxide is involved in laser radiation-induced analgesia …

Abstract Background and Objectives Analgesic properties of laser irradiation have been of
great interest in the field of dentistry. This study aimed at evaluating the analgesic effects of …

抄録 The analgesic effects in the course of application of therapeutic lasers to affected tissue
have been described in a number of works in the literature. Although a few scientific-based …

OBJECTIVES: To evaluate the analgesic effect of laser therapy on healthy tissue of mice.
STUDY DESIGN: Forty-five animals were divided in three groups of 15: A--infrared laser …

High-energy lasers are suitable for experimental pain stimulation because they selectively
activate the polymodal nociceptors. Argon laser light penetrates deep into the skin and …

The use of different lasers for stimulation in human experimental pain research has provided
a sensitive method for evaluation of thin nerve fiber functions. In this study, sensory and pain …

Low-power laser analgesic effect was generally accepted in clinical cases, whereas there
was no direct evidence to indicate that low-power laser irradiation suppressed an impulse …
