Avaliação da atividade analgésica do laser de baixa intensidade após exodontias simples: estudo clínico cego, randomizado e prospectivo.

Abstract

The objective of the present study was to evaluate the efficacy of low intensity laser in the control of postoperative pain in patients submitted to simple exodontia, at the Clinical School of Dentistry of the Universidade Federal de Campina Grande, Patos-PB. Sixty (60) patients were randomly divided into three groups. After surgery, all groups received laser application and medication to be taken, dipyrone sodium (500mg), group B, paracetamol (750mg) and group C, placebo medication. Pain measurements were performed in the immediate postoperative period, after 24 hours and 7 days. The data obtained were tabulated in the program Bioestat 5.0. The Kruskal Wallis test was used with a significance level of 95% to evaluate if there were significant differences between the groups. Regarding the results, when comparing group A and B in the first 24 hours and with 7 days observing the characterization of the scores, a greater efficacy of dipyrone sodium on paracetamol was demonstrated. In the group C scores, where the laser effect was evaluated after 24 hours and 7 days, a significant efficacy was observed in pain reduction. Statistically there were no significant differences between groups. It was concluded that the laser presented no statistical difference in relation to dipyrone sodium and paracetamol, however, it demonstrated analgesic efficacy when the pain scores were characterized, evidencing that it is a viable therapeutic alternative for greater postoperative comfort of the patient.
