Ibuprofeno e a associação de codeína + paracetamol frente a sensibilidade imediata no clareamento dentário: um ensaio clínico

Abstract

Sensitivity is the main adverse effect caused by tooth whitening. The aim of the present study was to compare the efficacy of ibuprofen and the combination of codeine + paracetamol in the control of the immediate sensitivity generated by dental office whitening with 35% hydrogen peroxide. Methods: Sixty volunteers were randomly selected and divided into three groups: Placebo (PL) 400 mg (n = 20), Ibuprofen (IB) 400 mg (n = 20) and Codeine 30 mg + Paracetamol 500 mg (N = 20). The volunteers were submitted to 2 bleaching sessions with 35% hydrogen peroxide in 2 applications of 20 min each. Medications were taken 1 hour before the bleaching procedure in both sessions. Sensitivity values were collected using a visual analog pain scale. Statistical analysis was done using ANOVA 1 Factor and post test of tukey, using Assistat® software. Results: There was a statistically significant difference between the treatments (p <0.01) (averages: PL: 4.7, IB: 4.8 and CP: 1.0). Conclusion: The treatment of codeine + paracetamol was more effective in eliminating the immediate sensitivity generated by tooth whitening with 35% hydrogen peroxide, with values close to zero, compared to ibuprofen and placebo.
