Effect of Low-Level Laser Therapy on Wounds in Intra-Oral Surgery
Oral Health Case Reports, 2016
During the last two decades, much has been written in both the scientific literature and the popular press about lasers and their use in dentistry. Both soft-and hard-tissue applications have been discussed, including frenectomy, gingival contouring, caries removal and bleaching. The aim of this study is evaluate and compare the effects of laser therapy on the surgical wound repair process and painful symptoms in patients undergoing bilateral teeth extractions at the Department of Dentistry, State University of Paraiba. Three sessions of laser therapy (GaAlAs) were performed for each patient. The first session was immediately after the surgical procedure, the second occurred 48-72 h after the first session, and the third and final at 7 days after surgery, coinciding with the removal of the sutures. Of the patients examined, 65.5% at the first assessment (after the second laser therapy session) and 75% at the second assessment (after the third session) exhibited a better degree of repair on the side treated with laser (STL) compared to the side not treated with laser (SNTL). There was no difference in edema between the STL and SNTL. Regarding pink tissue colour, there was an increase in its frequency, from 25%-62.5% of cases, on the STL between the first and second assessments. Bleeding also showed an increased frequency on the STL and decreased on the SNTL in the second assessment. Regarding painful symptoms, the results revealed that, on the STL, they decreased, from 62.5%-0% between the first and second assessments, and on the SNTL, from 87.5%-12.5%. Hence, low-power laser use appeared to be effective for the repair of intraoral surgical wounds, accelerating the degree of repair, improving tissue colour and reducing pain symptoms.

This study aimed to evaluate the anti-inflammatory and analgesic effects of intraoral application of low-level laser therapy (660 nm) to control pain, swelling and interincisal opening following the extraction of mandibular third molars. [Subjects and Methods] Ten patients underwent removal of lower third molars using the same surgical protocol and pharmacological approach. In the postoperative period, all patients received four consecutive daily sessions of low-level laser therapy, beginning 24 hours after the surgery. Intraoral applications using the diode laser with 660 nm wavelength in the continuous scan mode were performed covering the entire surgical area, which was divided into four quadrants, each of 1 cm 2 area at a distance of 1 cm. The energy applied at each point was 5 J/cm 2 during 8 seconds. [Results] The swelling and interincisal opening returned to normal 24 hours after the first low-level laser therapy application (Friedman test). Moreover, the pain intensity was reduced on the third postoperative day, according to the Friedman test. [Conclusion] Low-level laser therapy (660 nm), at the dosimetry used in this study, was effective in reducing postoperative pain and swelling following oral surgery.

LOW LEVEL LASER THERAPY AND ITS HIGH END APPLICATIONS IN DENTISTRY – A REVIEW
These unique characteristic makes the Laser useful for commercial and medical application. An understanding of the optimal therapeutic effect results when the wavelength best absorbed by the target tissue is selected for use, However the choice of the best laser for certain procedure depends on much more than just matching emission spectra of Laser to absorption spectra of tissue. The versatility of the instrument combined with latest achievement in Laser technology, compact design and affordability should appeal to dental professional seeking to optimize the procedure they currently perform and expand the number of service they offer. Taking into consideration the effects of the laser treatment, such as activation of microcirculation, production of new capillaries and thickening of the capillary net, anti-inflammatory, analgesic effect, stimulated growth and regeneration of cells, and accelerated bone consolidation, following the need for incorporating non-invasive methods for minimizing the pain and discomfort either during or after dental treatment, we consider that the use of Low level laser therapy is an excellent treatment option.

Low-level Laser Therapy: A Literature Review
International Journal of Laser Dentistry, 2015
LASER is an acronym for "Light Amplification by Stimulated Emission of Radiation." The arena of lasers has expanded to include light-emitting diodes and other sources of light. Various wavelengths used are in the range of red and near infrared spectrum. Each wavelength has a unique interaction with the respective target tissues. High doses of laser have certain drawbacks and, in order to overcome these issues, widespread research is going on low-level laser therapy (LLLT). Low-level laser therapy results in direct biostimulation action on various cells of the body. It is reported that LLLT could enhance the process of wound healing and also has stimulating effects on bone cells and can hasten the repair process of the bone. In spite of many reports of affirmative findings from experiments conducted in vitro, in animal models, and in randomized controlled clinical trials, the effects of LLLT remain debatable. On the contrary, additional research still needs to be done in order to check the efficacy for periodontal treatment. This article focuses on the effects of LLLT on various tissues, its dosage, mechanisms of action, and applications in the field of dentistry.

Aim: To perform a systematic review to evaluate the post-surgical effect of low-level laser therapy after tooth extraction on healing improvement and pain reduction. Material and methods: Two reviewers performed a database search of studies published between 1950 and 2015. The inclusion criteria were clinical studies that applied any regimen of low-level laser therapy after any type of tooth extraction and also compared this regimen with nonadjuvant therapy. There was no language restriction. All potentially relevant studies were identified by the title and the abstract. After the full-text analyses of the potentially relevant studies, the selected studies were included in the systematic review. Results: A total of 99 non-duplicated studies were found. After reviewing the articles, only 11 were included. The selected studies were critically analysed and classified in scores. None of the studies fulfilled all of the requirements in the quality assessment. Only four studies presented high methodological soundness. Conclusions: A decrease in pain level after tooth extraction was reported after low-level laser therapy; however, there is no evidence regarding the effect on tissue healing. Adequately powered and randomised controlled trials are required to address this issue. Clinical relevance Previous studies have identified low-level laser therapy as effective adjuvant therapy for healing and pain after tooth extraction. This systematic review assessed the effect of this therapy on improvement in healing and prevention of pain. This systematic review concluded that low-level laser therapy might be effective in decreasing pain level after tooth extraction; however, further research is needed to evaluate the effectiveness on healing improvement.
Role of Laser Therapy in Dentistry: A Review
International Journal of Biomedical Research, 2014
Lasers are the direct application of light energy with biomodulatory capacity on body cells. Photo acceptors (cytochrome c oxidase) can absorb low level lasers irradiation and transfer it inside mitochondria in order to provide cell energy (ATP) which is the product cytochrome c oxidase and Krebs cycle. In final the stimulation of ATP synthesis results in increased cell activity. Biomodulatory effects of low level laser therapy comprise the following: macrophages, lymphocytes, fibroblasts, endothelial cells and keratinocytes proliferation; increase ATP synthesis and cell respiration, growth factors and other cytokines release, change of fibroblasts to myofibroblasts; change in inflammatory mediators level (histamine and prostaglandins); increase in oxygen transport and improve in glucose consumption; changes in cell membrane potential and permeability, sodium/potassium pump excitation and more calcium removal, vasodilatation , angiogenesis & collagen synthesis. 5
