Resumo
O isolamento absoluto do campo operatório para realização de selante resinoso em fóssulas e fissuras tem sido apontado como um fator imprescindível no sucesso desta técnica, gerando maior qualidade e longevidade ao tratamento. Porém, o grampo utilizado no procedimento de isolamento exerce sobre o dente uma pressão e entra em contato com a gengiva, podendo causar dor e/ou desconforto. Esta situação indica a necessidade prévia de anestesia infiltrativa, que por sua vez, gera medo e ansiedade. Este ensaio clínico abrangeu um caráter experimental, terapêutico, de conveniência e duplamente cego, com delineamento boca dividida, cujo objetivo foi comparar a eficácia entre dois anestésicos tópicos, quando da colocação de grampo para a instalação do isolamento absoluto. Foram selecionadas 30 crianças, com idades entre sete e onze anos, com indicação de selantes de fóssulas e fissuras nos primeiros molares permanentes inferiores. Os anestésicos tópicos eleitos para a pesquisa foram: Cloridrato de Tetracaína (Líquido) e Benzocaína (Gel). O primeiro utilizado na Oftalmologia como anestésico em algumas cirurgias, e o segundo utilizado na Odontologia como pré-anestésico. Foram aplicadas escalas de dor, a fim de mensurar a sensibilidade e intensidade dolorosa das crianças. Efetuou-se a análise exploratória dos dados, com uma abordagem não paramétrica. Foi utilizado o teste de Sinais de Postos de Wilcoxon, nível de significância de 5%. Foi verificado que houve diferença estatisticamente significante para a Escala Numérica. Nesta pesquisa, o Cloridrato de Tetracaína mostrou-se mais eficaz que a Benzocaína. Não houve efeitos adversos aos fármacos experimentados. Concluiu-se que inserir o anestésico tópico oftálmico Cloridrato de Tetracaína na rotina da clínica odontológica consiste numa alternativa viável no controle da dor, proporcionando maior conforto e consequentemente controlando o medo e ansiedade dos pacientes.
The absolute isolation of the operative field for the realization of resinous sealant in pit and fissures has been pointed out as an indispensable factor in the success of this technique, generating greater quality and longevity to the treatment. However, the clamp used in the insulation procedure exerts a pressure on the tooth and comes into contact with the gums and may cause pain and/or discomfort. This situation indicates the prior need for infiltration anesthesia, which in turn generates fear and anxiety. This clinical trial covered an experimental, therapeutic, convenience and doubly-blind character, with split mouth design, whose objective was to compare the efficacy between two topical anesthetics, when the staple placement for the installation of the Absolute isolation. 30 children were selected, aged between seven and eleven years, with an indication of pit sealants and fissures in the first lower permanent molars. The topical anesthetics chosen for the research were: Tetracaine hydrochloride (liquid) and Benzocaine (Gel). The first used in ophthalmology as an anesthetic in some surgeries, and the second used in dentistry as preanesthetic. Pain scales were applied in order to measure the painful sensitivity and intensity of children. Exploratory analysis of the data was carried out, with a non-parametric approach. We used the Wilcoxon signal test, 5% significance level. It was verified that there was statistically significant difference to the numerical scale. In this research, tetracaine hydrochloride proved to be more effective than benzocaine. There were no adverse effects on the experienced drugs. It was concluded that inserting the topical anesthetic ophthalmic hydrochloride tetracaine in the routine of the dental clinic consists of a viable alternative in the control of pain, providing greater comfort and consequently controlling the fear and anxiety of patients.
