ABSTRACT
Low-level laser therapy is a tool employed in the management of post-operative inflammation process and in the enhancement of reparative process. The aim of the study was to perform histological evaluation of dental and periodontal ligament of rats central upper-left incisor teeth re-implanted and irradiated with low-level laser (InGaAl, 685 nm, 50 J/cm(2)) 15, 30, and 60 days after re-implantation. Seventy-two male rats had the central upper left incisor removed and kept for 15 min on dry gauze before replantation. Laser was irradiated over the root surface and empty alveolus prior replantation and over surrounding mucosa after the re-implantation. After histological procedures, all slices were analyzed regarding external resorption area and histological aspects. We observed an increase of root resorption (p < 0.05) in the control group compared to the laser group at 15, 30, and 60 days. These results showed that the laser groups developed less root resorption areas than the control group in all experimental periods. Additionally, histological analysis revealed less inflammatory cells and necrotic areas in laser groups.

Historically, oral soft tissue surgery on infants and young children was completed in the operating room under a general anesthetic agent. Many children were referred to an oral surgeon and required a physician's physical examination and medical clearance for a hospital admission. potentially placed a child at risk during the use of a general anesthetic for an elective procedure, which may not have insurance benefits. Traditional methods of oral surgery using scalpels or electrosurgery may produce significant postoperative discomfort and require sutures and prolonged healing. Lasers provide a simple and safe in-office alternative for children while at the same time reducing the chances of infection, swelling, discomfort, and scaring.

A aplicação de diferentes lasers de baixa potência de intensidade é um método alternativo na terapia de traumatismos. O objetivo deste trabalho é apresentar o uso do laser de diodo no tratamento de um paciente traumatizado por acidente de bicicleta. Um laser de AsGaAl de 670 nanometros com 50 mW foi usado nesta proposta de trabalho.Foram realizadas três sessões no intervalo de 48 horas entre elas. A densidade de energia aplicada foi de 15 J/cm2 na região do lábio superior, divididos em cinco pontos, cada ponto recebeu 3 J/cm2. A redução da inflamação, reparação tecidual e dor reduziram em sete dias. Não foi utilizado qualquer tipo de droga. O uso do laser de baixa potência apresentou ser muito eficiente. É uma alternativa para o tratamento de traumatismos nos dentes e tecidos mole, dando conforto ao paciente num curto espaço de tempo.
