“…According to physiological experiments using the GaAlAs laser at 830 nm, this effect is caused by blocking the depolarization of C-fiber afferents (Wakabayashi et al 1992b(Wakabayashi et al , 1993. GaAlAs laser emissions at 904 nm have an analgesic effect on the cat tongue although the mechanism remain unclear (Mezawa et al 1988). GaAlAs laser irradiation at a maximum power of 60 mW does not affect the enamel or Table 2.…”

Background, aims: Since the development of the ruby laser by Maiman in 1960, a variety of papers on potential applications for lasers in dentistry have been published. The purpose of this paper is to summarise laser applications for the treatment of dentine hypersensitivity. The effects of laser on pulp tissue and problems on laser treatment are also reviewed. This article reviews the role of lasers for the treatment of dentine hypersensitivity since 1985, summarises many research reports from the last decade, and surmises what the future may hold for lasers in this treatment. Method: To date, 4 kinds of lasers have been used for the treatment of dentine hypersensitivity, and the effectiveness ranged from 5.2 to 100%, which was dependent on the laser type and parameters used. The mechanism involved in laser treatment of dentine hypersensitivity are relatively unknown. Results: These require clarification to result in safely effective treatment optimization. In general, the efficiency for the treatment of dentine hypersensitivity using lasers is higher than other methods, but in severe cases, it is less effective. Conclusion: It is necessary to consider the severity of dentine hypersensitivity before laser use.

“…In vivo studies of the analgesic effect of LLLT on nerves supplying the oral cavity have d e m o n s t r ated that LLLT decreases the firi n g frequency of nociceptors, with a threshold effect seen in terms of the irradiance required to exert maximal suppression. 61 In vivo, LLLT selectively inhibits a range of nociceptive signals arising from peripheral nerves, including neuronal discharges elicited by pinch, cold, heat stimulation, and chemical irri t at i o n . 6 2 , 6 3…”

Despite more than 30 years of experience with low level laser therapy (LLLT) or 'biostimulation' in dentistry, concerns remain as to its effectiveness as a treatment modality. Controlled clinical studies have demonstrated that while LLLT is effective for some specific applications, it is not a panacea. This paper provides an outline of the biological basis of LLLT and summarizes the findings of controlled clinical studies of the use of LLLT for specific soft tissue applications in dentistry. Areas of controversy where there is a pressing need for further research are identified.

“…In consistent with the above findings, a number of electrophysiological experiments were carried out, to assess neuronal mediated inhibitory effects of laser irradiation [124][125][126]. Laser irradiations were able more specifically to influence the nerve conduction of small diameter, thinly myelinated A and unmyelinated C fibres.…”

The Use of Photomedicine in Musculoskeletal Pain

Musculoskeletal pain is a major cause of disability. Myofascial trigger points (MTrPs) in particular are a common source of pain in a substantial number of patients presenting at a pain clinic. Many different invasive and non-invasive forms have been advocated to the treatment of MTrPs. However, favourable outcome rates are inconsistent and some of these treatment forms described are often painful and have potentially dangerous side effects. Photomedicine including the coherent light sources (lasers) and more recently, non-coherent light sources have been reported to be beneficial in soft tissue lesions including MTrPs. Their beneficial therapeutic effects can be obtained without undesired effects. The main intentions of this chapter are to bring the attention of the doctors and physical therapists to the scientific approach of photomedicine, in particular laser therapy for the relief of pain arising from MTrPs, and to demonstrate how this type of therapy can be utilized in a rational manner for the relief of musculoskeletal pain. In addition, it has been found necessary to include or to start with an overview of the recently recognized diagnostic and therapeutic importance of MTrPs. Attention will therefore first be drawn mainly to incidence, types, aetiology, clinical diagnostic criteria and conventional forms of MTrPs.
