A recessão gengival pode ser compreendida como a migração do tecido marginal que circunda o dente de maneira apical à junção cemento-esmalte, podendo afetar um ou múltiplos dentes. Dentre as diversas técnicas de recobrimento radicular, a de tunelização se mostra bastante eficaz em recessões gengivais rasa, estreitas ou amplas. Essa técnica tem como característica a preservação de papilas, além de não necessitar de incisões relaxantes, sendo mais conservadora. O objetivo desse trabalho foi realizar uma análise da literatura a fim de analisar a técnica de tunelização em cirurgias de recobrimento radiculares. Nesse sentido, foi realizado uma pesquisa no banco de dados Pubmed, utilizando apenas artigos em inglês dos últimos cinco anos e com os descritores "gingival recession” and “tunnel”. Foram encontrados vinte e um artigos, sendo utilizados apenas onze, pois se adequavam ao tema proposto. Nesse sentido, foi observado que o uso do túnel com enxerto de tecido conjuntivo para recobrimento radicular garante previsibilidade, ótimo suprimento sanguíneo e nutrição ao enxerto, cicatrização mais rápida. No entanto, o enxerto retirado do palato proporciona uma grande morbidade pós-operatória. Com isso, o uso dessa técnica em recessões RT1 de Cairo é bastante eficaz. Entretanto, suscita- se mais estudos para aprimorar esse método e buscar uma solução menos dolorosa para o sítio doador do enxerto.
