Control of pain in patients undergoing gingivectomy and gingivoplasty with low intensity laser / Controle da dor em pacientes submetidos a gengivectomia e gengivoplastia com laser de baixa intensidade

Objective: To evaluate the efficiency of Laser Low Intensity (LLI) in pain control and reduction of analgesic consumption after gingivectomy and gingivoplasty. Methods: Twenty patients with gingival hyperplasia were randomly divided into two groups with 10 subjects each. In the test group it was applied after gingivectomy / gingivaplasty, low intensity laser in the operative wound and prescription only in case of pain, while in the control group only analgesia was performed in case of pain. Results: The laser was applied at 3 points in the region of periodontal surgery. The irradiation was performed in a single session, using diode laser (808 nm, 100nW, 100J / cm², 30 s). Pain was assessed by Visual Analogue Scale, as well as the amount of analgesics ingested by the patient. In the test group, 80% of the individuals did not report postoperative pain, those who reported symptomatology, were identified only as mild discomfort. The analysis of the data showed a statistically significant difference when compared to the higher postoperative pain between the groups (p = 0.026). However, there was no difference in the evaluation of analgesic use. Conclusion: Based on our results, it is suggested that LLI therapy decreases the intensity of postoperative pain in periodontal surgeries (AU)

Impacto na qualidade de vida de cirurgia de aumento de coroa clínica em área estética associada ou não à laserterapia de baixa intensidade / Impact on the quality of life of the clinical crown surgery in a esthetic area associated or not to low intensity lasertherapia

Objetivo: este estudo avaliou o impacto da estética vermelha do sorriso na qualidade de vida de pacientes submetidos à cirurgia periodontal de gengivectomia/gengivoplastia, utilizando laserterapia para o controle da dor pós-operatória. Metodologia: Vinte indivíduos foram distribuídos aleatoriamente em dois grupos com 10 integrantes: no grupo teste, foi aplicado laser de baixa intensidade na ferida cirúrgica e prescrição de analgésico; enquanto, no grupo controle foi realizada apenas a terapia com analgésico. A irradiação realizada numa sessão única, por 30 segundos em cada ponto, com Laser de Diodo (808 nm, 100 mW, 105J/cm2). O laser irradiou em 3 pontos, faces mesiovestibular, distovestibular e vestibular dos elementos envolvidos na cirurgia. No pós-operatório de 5 horas e do 1o ao 7º dias a Escala Visual Analógica avaliou a dor e quantidade de analgésico ingerida pelo paciente. O impacto das alterações estéticas no sorriso foi avaliado pelo OHIP-14 em três momentos: no pré-operatório e após 7 e 21 dias. Resultado: não houve diferença significativa entre os grupos com relação à dor e número de analgésico ingerido no período de pós-operatório avaliado. Houve uma redução significativa no valor do OHIP-14 total (p ≤ 0,05) em ambos os grupos e na dimensão desconforto psicológico (p = 0, 006) no grupo teste após a correção das alterações estéticas do sorriso dos indivíduos. Conclusão: a cirurgia periodontal estética impactou positivamente na qualidade de vida, principalmente na dimensão desconforto psicológico. O LBI no controle da dor e redução de analgésicos não apresentou significância (AU_

Objective: This study evaluated the impact of the red smile aesthetics on the quality of life of patients submitted to gingivectomy/gingivoplasty periodontal surgery, using laser therapy for postoperative pain control. Methodology: Twenty individuals were randomly assigned to two groups with 10 members: in test group, low intensity laser was applied to the surgical wound and prescription of analgesic; while in the control group, only analgesic therapy was performed. The irradiation performed in a single session, for 30 seconds at each point, with Diode Laser (808 nm, 100mW, 105J / cm²). The laser light irradiated in 3 points, mesiobuccal, distobuccal and vestibular faces of the elements involved in the surgery. In the postoperative period of 5 hours and from the 1st to 7th day, the Visual Analogue Scale evaluated the pain and amount of analgesic ingested by the patient. The impact of the aesthetic changes on the smile was evaluated by the OHIP-14 in three moments: in the preoperative and after 7 and 21 days. Result: There was no significant difference between the groups regarding pain and number of analgesic ingested in the postoperative period evaluated. There was a significant reduction in the value of total OHIP-14 (p ≤0.05) in both groups and in the psychological discomfort dimension (p = 0.006) in the test group after correction of aesthetic changes in the individuals' smile. Conclusion: Aesthetic periodontal surgery positively influenced the quality of life, especially in the psychological discomfort dimension. LIL in pain control and analgesic reduction did not show any significance. (AU)
