Previous issue date: 2007-03-01 / Many studies have been made to understand the process of tissular cicatrization, as well as the possible effects of laser therapy in the wound healing. However, the influence of low frequency laser irradiation in the repairing process is not completely understood. Our study has the purpose to assess clinically the effect of postoperative irradiation of the low frequency laser in humans, and the gingival repairing process postgingivoplasty performed with the extern bevel technique. Twenty-four patients with inflammatory gingival hyperplasia were enrolled in this study, which did not reduce with basic periodontal procedures, and patients with melanin pigmentation, with esthetic indications. After surgery the test group, randomly selected by a drawing, received laser application with energy density of 4 J/cm2, immediately after surgery and each 48 hours, during a week, with a total of 4 sections. The control group did not receive irradiation. The visual clinical analyses were performed by a single blind examiner, in the 2nd, 4th, 6th, 8th, 15th and 21st days post surgery. For statistic analyses of the data was used a Q-square test. Concerning the color, the results showed a better wound healing during days 6 to 8. when assessed the degree of progress of surgical wound, the results showed that the test group had a better cicatrization compared with the control group in the 2nd, 6th, 8th and 15th days post surgery, and at the 21st day both groups had the same results. Our results confirm that the laser had clinical influence in the repairing process after gingivoplasty surgery during days 2 to 15 post surgery / V?rios estudos t?m sido realizados para compreender o processo de reparo tecidual, bem como os poss?veis efeitos da terapia a laser na cicatriza??o de feridas. Entretanto, a influ?ncia da irradia??o do laser de baixa intensidade no processo de reparo ainda n?o est? totalmente clara. Nosso trabalho teve como objetivo avaliar clinicamente, em humanos, o efeito da irradia??o p?s-operat?ria do laser de baixa intensidade no processo de reparo gengival ap?s gengivoplastia. Participaram desse estudo 24 pacientes portadores de hiperplasia gengival inflamat?ria, que n?o regrediu com os procedimentos b?sicos periodontais, e portadores de pigmenta??o mel?nica, com indica??es est?ticas. Ap?s a cirurgia o lado teste, escolhido aleatoriamente atrav?s de um sorteio, recebeu aplica??o do laser com densidade de energia de 4 J/cm2, imediatamente o t?rmino da cirurgia e a cada 48h, durante 1 semana, totalizando 4 sess?es. O lado controle n?o foi irradiado. A an?lise cl?nica visual foi feita por um ?nico examinador de maneira cega, no 2?, 4?, 6?, 8?, 15? e 21? dia do p?s-operat?rio. Para a an?lise estat?stica dos dados obtidos foi utilizado o teste qui-quadrado. Com rela??o ? cor, os resultados obtidos mostraram um melhor reparo cicatricial durante o per?odo de 6 a 8 dias. Quando avaliado o grau de evolu??o da ferida cir?rgica, os resultados mostraram que o lado teste apresentou uma melhor cicatriza??o em rela??o ao lado controle no 2?, 6?, 8? e 15? dia de p?s-operat?rio, entretanto, no tempo de 21 dias ambos foram considerados iguais. Podemos constatar que o laser influenciou clinicamente no processo de reparo ap?s cirurgias de Gengivoplastia no per?odo de 2 a 15 dias de p?s-operat?rio
