Resumo
A retração gengival é um problema altamente prevalente, podendo atingir até 100% dos indivíduos com mais de 50 anos de idade. Para lidar com as recessões, diversas técnicas cirúrgicas foram desenvolvidas. A que apresenta melhores resultados é a técnica de retalho posicionado coronariamente (RPC), feita de forma isolada ou associada ao enxerto de tecido conjuntivo (ETC). No entanto, existem na literatura diversos estudos que demonstram que os pacientes fumantes têm um pior prognóstico no tratamento de recessões gengivais quando comparados aos pacientes não fumantes. Assim, há a necessidade de testar novas abordagens que aumentem a previsibilidade do tratamento das recessões gengivais para esse grupo de pacientes. Portanto, o objetivo do presente estudo foi avaliar influência da terapia com laser de baixa intensidade associado à técnica de enxerto de tecido conjuntivo para recobrimento radicular em pacientes fumantes. Para tal, foi realizado um ensaio clínico duplo cego, controlado, randomizado seguindo as normativas do CONSORT-STATEMENT 2010. Foram selecionados 28 pacientes fumantes apresentando retração gengival que foram divididos nos grupos teste: enxerto de tecido conjuntivo associado à aplicação de laser de baixa intensidade e o grupo controle: enxerto de tecido conjuntivo associado à aplicação SHAM de laser em indivíduos fumantes. Foram avaliadas a taxa de recobrimento, estética e conforto dos pacientes aos, 3 e 6 meses após o procedimento. Encontramos médias de recobrimento parcial de 69% e 70% e de recobrimento total de 22% e 21%, respectivamente para os grupos teste e controle. Não havendo diferenças estatisticamente significantes entre os grupos em nenhum dos parâmetros avaliados. Baseado nos resultados desse estudo pode-se concluir que a aplicação de LBI não aumentou a porcentagem de recobrimento radicular completo e melhora da estética e dor pós-operatória em pacientes fumantes.
Gingival recession is a highly prevalent problem and can reach up to 100 % of individuals over 50 years of age. To cope with recessions, various surgical techniques have been developed. As with the best results is the technique of coronally advanced flap (CAF), taken in isolation or associated with connective tissue graft (CTG). However, in the literature there are several studies that show that smokers have a worse prognosis in the treatment of gingival recession compared to non- smokers. Thus there is the need to test new approaches that increase the predictability of the treatment of gingival recession for this group of patients. Therefore, the aim of this study is to evaluate the influence of therapy with lowintensity laser technique associated with connective tissue graft for root coverage in smokers. To do so, double- blind clinical trial, controlled following the regulations of the CONSORT STATEMENT - 2010 will be conducted. We selected 28 patients with gingival recession smokers who were divided into test groups: connective tissue graft associated with the application of low intensity laser and the control group: connective tissue graft associated with laser SHAM application in smokers. The rate of coverage, aesthetics and comfort of patients at 45 days, 2, 3 and 6 months will be evaluated after the procedure We find means of partial coverage of 69% and 70% and total coverage of 22% and 21% respectively for the test and control groups. No statistically significant differences between groups in all evaluated parameters. Based on the results of this study it can be concluded that the application of LILT did not increase the percentage of complete root coverage and improved aesthetics and post-operative pain in smokers.
