ABSTRACT
The aim of this study was to evaluate the efficacy of two desensitizing agents in the reduction of dentin hypersensitivity in a randomized, double-blind, split-mouth clinical trial. Seventy-seven teeth from 13 patients that presented some degree of sensitivity to probing and/or air stimulation were treated with one of the following desensitizing agents Oxa-Gel (G1), Sensi Kill (G2) and placebo gel (G3 - control). According to paired t-test, all treatments, even the placebo gel, were capable of reducing sensitivity scores for both stimuli. Analysis of data by ANOVA and Tukey's test (?=0.05) showed that the sensitivity scores were significantly lower only for Sensi Kill in comparison to the other products (Oxa-Gel and placebo), when air stimulus was applied. It may be concluded that treatment with Sensi Kill presented a slightly better performance in reducing dentin hypersensitivity when compared to the other desensitizing agent.
RESUMO
O objetivo desse estudo foi avaliar a eficiência de dois agentes dessensibilizantes na redução da hipersensibilidade dentinária, em um estudo clínico aleatório do tipo boca-dividida e duplo-cego. Setenta e sete dentes de 13 pacientes que apresentavam algum grau de sensibilidade à sondagem e/ou estímulo ao ar foram tratados com um dos seguintes agentes dessensibilizantes Oxa-Gel (G1), Sensi Kill (G2) e gel placebo (G3-controle). De acordo com o teste t pareado, todos os tratamentos, inclusive o placebo, foram capazes de reduzir os escores para ambos os estímulos. A análise dos dados pelos testes de ANOVA e de Tukey (?=0,05) demonstrou que os escores de sensibilidade foram significantemente menores somente para o Sensi-Kill em comparação aos outros produtos (Oxa-Gel e placebo) quando o estímulo ar foi aplicado. Pode-se concluir que o tratamento com Sensi-Kill apresentou um desempenho ligeiramente melhor na redução da hipersensibilidade dentinária quando comparados aos outros agentes dessensibilizantes.
