ABSTRACT

RESUMEN: Objetivo: Comparar la eficacia clínica de dentífricos en base a arginina al 8%/ monofluorfosfato de sodio 1450 ppm versus nitrato de potasio al 5%/fluoruro de sodio 2500 ppm en la terapia de la hipersensibilidad dentinaria (HSD). Materiales y método: Ensayo clínico, aleatorio, controlado, doble ciego, de grupos paralelos. Treinta y cuatro voluntarios de 18 a 70 años, con HSD en escala Visual Análoga (EVA) ≥4 en 2 ó más dientes no molares, fueron distribuidos aleatoriamente en 2 grupos: grupo T1 (n=16): dentífrico de Arginina al 8%/ monofluorfosfato de sodio 1450 ppm; y grupo T2 (n=18): dentífrico de nitrato de Potasio al 5%/fluoruro de sodio 2500 ppm. Se evaluó HSD en EVA con estímulos evaporativos y térmicos, y se compararon sus valores, así como el grado promedio de HSD y su reducción (∆HSD), intra e intergrupal, al inicio y a las 4 semanas de tratamiento. Resultados: Ambos dentífricos disminuyeron el grado promedio de HSD entre el inicio y las 4 semanas de tratamiento (T1: 5.03 ± 1.23 versus 2.60 ± 1.27, p<0.05; T2: 4.73 ± 1.51 versus 2.71 ± 1.17, p<0.05). No hubo diferencias estadísticamente significativas entre ambos dentífricos al comparar el grado promedio de reducción de HSD durante la terapia (∆HSD T1: -2.43 ± 1.22 versus ∆HSD T2: -2.27 ± 1.42). Los datos fueron analizados en Stata versión 11. Conclusiones: Ambos dentífricos fueron clínicamente eficaces en reducir la HSD a las 4 semanas, sin existir diferencias estadísticamente significativas entre ambos.


ABSTRACT: Aim: To compare the clinical efficacy of 8% arginine/1450ppm sodium monofluorophosphate and 5% potassium nitrate/2500 ppm sodium fluoride dentifrices in the treatment of dentin hypersensitivity (DH). Methods: Parallel-design, double-masked, randomized controlled clinical trial. Thirty four volunteers aged 18 to 70 years, with DH and a visual analog scale (VAS) score ≥4 at least in two or more non-molar teeth, were randomized in two groups: T1 (n=16): 8% arginine/1450 ppm sodium monofluorophosphate dentifrice; and T2 (n=18): 5% potassium nitrate/2500 ppm sodium fluoride dentifrice. DH was assessed with evaporative and thermal stimuli; and their VAS measurements, mean DH value and DH reduction (∆DH) were compared, inside and between the groups at baseline and 4-week follow-up. Data were analysed through Stata® V11 program. Results: Both toothpastes decreased mean DH value between baseline and 4 weeks (T1: 5.03 ± 1.23 versus 2.60 ± 1.27, p<0.05; T2: 4.73 ± 1.51 versus 2.71 ± 1.17, p<0.05). There were no statistical differences between both dentifrices in mean DH reduction values during therapy (∆HSD T1: -2.43 ± 1.22 versus ∆HSD T2:-2.27 ± 1.42). Conclusions: Both dentifrices had clinical efficacy in decreasing DH in a 4- week therapy, without statistical differences between both of them.
