Introdução: O manejo no atendimento odontológico infantil torna-se fatigante quando não há cooperação por parte da criança e/ou dos responsáveis. A fim de minimizar esses quadros, quando não existe sucesso das técnicas de abordagem comportamental tradicionais, métodos terapêuticos alternativos têm sido amplamente estudados, em especial a sedação consciente com óxido nitroso associada ou não a fármacos sedativos. Objetivo: Dessa forma, objetivou-se realizar uma revisão crítica da literatura norteando o cirurgião-dentista sobre o uso do óxido nitroso e sua associação a fármacos, esclarecendo suas indicações, vantagens e desvantagens. Métodos: Foi realizada uma busca integrativa da literatura nacional e internacional, entre 2004 a 2019, nas bases Bireme e PubMed, utilizando os descritores: sedação consciente, ansiedade no tratamento odontológico e óxido nitroso. Resultados: No total, 43 artigos foram incluídos nesse estudo. O óxido nitroso tem sido bastante utilizado na odontologia, especialmente na odontopediatria. Este atua no sistema nervoso, promovendo uma leve depressão do córtex cerebral e não deprime o centro respiratório, sendo considerado seguro. A técnica pode ser combinada a outros fármacos, como Midazolam e Prometazina, sendo que cada abordagem medicamentosa apresenta suas indicações e vantagens específicas. Conclusão: A sedação consciente mostra-se como um método viável, e quando bem indicada é considerada segura. Seu papel na Odontologia vem sendo consolidado com o tempo, em decorrência dos inúmeros benefícios encontrados. No entanto, ainda existe certa resistência na utilização da mesma, tanto por parte dos responsáveis como também de alguns profissionais.
Descritores: Sedação Consciente; Ansiedade ao Tratamento Odontológico; Óxido Nitroso.
