Abstract

The low intensity laser therapy (LLLT) has been indicated as coadjuvant treatment of postoperative dental extraction surgery. Objective: The aim of this study was to evaluate the clinical and radiological findings of LLLT in the surgery for extraction of unerupted third molars. Material and method: Eight patients were submitted to extraction of mandibular third molar. The left tooth was treated with laser during surgery and for another 2 days after surgery (Laser Group). The right tooth surgery was performed after 15 days and did not receive laser therapy (control group). Clinical evaluation of the postoperative period was based on the measuring of edema and analysis of  a questionnaire to assess pain. After 40 days of each surgery, digital periapical radiographs were made and measured the optical density of bone repair were analyzed using the Image J. The data obtained in the measurement of edema and analysis of optical density were tested using Student t test. Result: The level of pain in postoperative patients was lower in the laser group compared to the control group. However, in the measurement of edema and analysis of optical density of radiographs there was no statistically significant difference in the laser group compared to control. Conclusion: According to the parameters used in this study, we can concluded that the application of  LLLT promoted analgesia postoperatively, but did not show effects on edema and bone repair.

Resumo

O laser em baixa intensidade tem sido indicado como tratamento coadjuvante no pós-operatório da cirurgia de extração dentária. Objetivo: O objetivo desse trabalho foi avaliar os efeitos clínicos e radiográficos do laser em baixa intensidade na cirurgia de exodontia de terceiros molares inclusos. Material e método: Oito pacientes foram submetidos à extração dos terceiros molares inferiores inclusos. O dente esquerdo foi tratado com laser durante a cirurgia e por mais 2 dias do pós-operatório (Grupo Laser). A cirurgia do dente direito foi realizada após 15 dias e não recebeu laserterapia (Grupo Controle). A avaliação clínica do pós-operatório foi baseada na medida do edema e análise de questionário para avaliação da dor. Após 40 dias de cada cirurgia, foram feitas radiografias periapicais digitais para medida das densidades ópticas da reparação óssea por meio do programa Image J. Os dados obtidos na medida do edema e análise de densidade óptica foram submetidos ao teste estatístico t de Student. Resultado: O nível de dor dos pacientes no pós-operatório foi menor no grupo laser em relação ao grupo controle. Entretanto, na medida do edema e na análise de densidade óptica das radiografias não houve diferença estaticamente significante do grupo laser em relação ao grupo controle. Conclusão: De acordo com os parâmetros utilizados nesse estudo, concluiu-se que a aplicação do laser em baixa intensidade promoveu analgesia  no pós-operatório, porém não teve efeito sobre o edema e a reparação óssea.
