Os lasers de baixa potência são utilizados para fins terapêuticos e bioestimuladores, agindo principalmente como aceleradores em processos cicatriciais, além de possuírem efeitos redutores de dor e anti-inflamatórios. A cicatrização envolve fenômenos biológicos como alterações vasculares e celulares, proliferação epitelial, proliferação de fibroblastos, revascularização e contração da ferida. Em tecidos epiteliais, o laser causa a proliferação, migração de células e ativa os fatores de crescimento. Já em tecido conjuntivo, atua aumentando a síntese de colágeno por fibroblastos, além de aumentar a vascularização ao promover angiogênese. Este artigo tem por objetivo relatar um caso de exposição óssea pós-cirúrgica tratada com terapia a laser de baixa intensidade, demonstrando aspectos clínicos e teóricos, além de analisar os efeitos da laserterapia e sua importância no processo de cicatrização. Em casos de exposição óssea uma alternativa viável é a enxertia de tecido gengival. No entanto, a necessidade de dois procedimentos cirúrgicos na área doadora e da receptora pode apresentar-se como desvantagem na aplicabilidade da técnica. Considera-se que a laserterapia possibilita a regeneração com ausência de procedimentos cirúrgicos, além de promover o aumento do fluxo sanguíneo e controle de processos inflamatórios. Pode-se concluir que a laserterapia de baixa intensidade representa um auxílio no processo de cicatrização e possibilitou a resolução do caso clínico de maneira eficaz.Descritores: Lasers; Odontologia; Cicatrização.ReferênciasCavalcanti TM, Almeida-Barros RQ, Catão MHCV, Feitosa APA, Lins RDAU.

The biological effects promoted by low power laser result in faster wound healing. However, wounds are very complex systems from both host and microbial point of view. Since infection is a common cause of delayed wound healing, it is important to understand the effect of low-level laser therapy in bacterial growth. This mini-review summaries the current evidence about effects of low level laser on bacteria vitro studies.Key-words: Low power laser, infected injury, bacteria.

Introduction: Liposuction has undergone many revisions since 1980, the most notable being the introduction of the tumescent technique of local anesthesia by Jeffery Klein, MD. Since then, in an effort to improve the aesthetics of the technique and the ease and safety of the procedure, other techniques have been introduced. These include superficial liposuction, UAL, external ultrasonic liposuction, mechanically assisted liposuction, and, most recently, laser-assisted liposuction. Materials and Methods: Four centers in the United States, operating under an 1RB protocol, performed liposuction with the tumescent technique of local anesthesia on specified cosmetic units of the body. One side was exposed to 635-nm laser therapy after tumescence was achieved, whereas the contralateral side was not. Observations were recorded during surgery and at 2 weeks postoperatively. Results: Observations of intraoperative technique did not show an advantage to laser-assisted liposuction. Observations of the postoperative course were equivocal, though there was evidence of reduction of edema in certain patients. Discussion: The addition of laser therapy to liposuction technique is based on years of experience demonstrating improved wound healing using a technique of low-level laser therapy. Although the recorded observations did not support an advantage to the addition of laser therapy, there was a paradoxical difference of opinion among patients and surgeons who participated in the study. These individuals believed that, compared with patients not treated with low-level laser therapy, there was at least a reduction in degree and duration of postoperative pain and induration. As low-level laser therapy may have systemic effects on wound healing, comparing treated and untreated contralateral sides may not be valid because both sides experienced improvements in postoperative course. Laser-assisted liposuction has a potential advantage, not supported by this study, in the intraoperative and postoperative course of liposuction surgery. New studies using double-blind techniques will need to be conducted.

Background and objectives: Diode laser has been the most popular low-level laser therapy (LLLT) technique in dentistry due to its good tissue penetration, lower financial costs, small size for portable application, and convenience to use. A series of recent studies with 940 nm or 980 nm lasers demonstrated that LLLT showed positive effects after third molar extraction or periodontal flap surgery. However, the effects of LLLT on intraoral mucosal wound healing after surgical incision have not yet been determined in human clinical study. Materials and Methods: The present study was performed to determine the efficacy and safety of 915 nm wavelength low-level laser therapy (LLLT) in mucosal wound healing. A total of 108 Sprague–Dawley rats were used. They were divided into three groups: Abrasive wound group, immediate LLLT once group, and daily LLLT group. As a clinical study, a total of 16 patients with split-mouth design subjected to bilateral mandibular third molar extraction were allocated into the LLLT group and placebo group. The process of LLLT was performed on postoperative days 0, 1, and 7, and parameters related to wound healing were analyzed on days 1, 7, and 14. Results: Repeated laser irradiation promoted mucosal wound healing of the rats. In the clinical study, although there were no significant statistical differences between the LLLT and placebo groups in all inflammatory parameters, the early stage mucosal healing tendency of wound dehiscence was higher in the LLLT group than in the placebo group clinically on postoperative day 1. Conclusions: The present results showed that 915 nm LLLT could be applied safely as an auxiliary therapy for mucosal wound healing.
