Efeito da aplicação ativa e passiva de agentes dessenssibilizantes no tratamento de hipersensibilidade dentinária: estudo clínico randomizado e duplo cego

Abstract

Objectives: This study aimed to assess the effect of active and passive application of desensitizing agents in the management of dentin hypersensitivity (DH). Methods: A total of sixty-two teeth with DH were randomly assigned to two treatment groups (n = 31): G1, Nitrate + Gluma (active application); G2, Nitrate + Gluma (passive application). Pain responses to thermal-evaporative and tactile stimuli were evaluated using the visual analog scale (VAS). Re-evaluations took place immediately after each application, and at 1 week, 1 month, 2 months, and 3 months post-treatment. Data were analyzed using one-way ANOVA with repeated measures followed by Dunnett's test for intragroup comparisons, and two-way ANOVA with repeated measures followed by Tukey's test for intergroup comparisons, with a significance level set at 5%. Results: Pain levels significantly decreased after treatment in all groups. Intergroup analysis revealed no significant differences in VAS score changes across the different time points. Conclusion: Both active and passive application of desensitizing agents were effective in alleviating DH. Clinical Relevance: Both methods of desensitizing agent application provide comparable results in managing dentin hypersensitivity, offering flexibility for clinicians in selecting the most practical approach without affecting treatment efficacy.
