  • To evaluate the effect of oxalic acid in cervical hypersensitivity, used under two different resin restorations one based on methacrylate and another based on silorane. Methods: 19 patients with “LCNC with hypersensitivity” were distributed into 4 groups according to treatment: G1 (n = 31): 0.5% oxalic acid (Desenssiv, SSWhite) + Z250 (3MESPE), G2 (n = 31): 0.5% oxalic acid + Filtek Silorane - P90 (3MESPE), G3 (n = 30): Distilled water + Z250; G4 (n = 30): Distilled water + Filtek Silorane - P90. Two clinical calibrated (kappa> 0.75) evaluated the sensitivity of the teeth: Before treatment, at 30, 60 and 90 days post-treatment (VAS). Results: The 4 groups at 30, 60 and 90 days reduced HS compared with the baseline (p <0.05). G1 and G2 showed less HS than G3 and G4 (p <0.05). Conclusion: The 4 restorative procedures significantly reduce the hypersensitivity, 30, 60 and 90 days compared to the baseline.
  • Evaluar el efecto del ácido oxálico en la hipersensibilidd cervical, utilizado bajo dos diferentes restauraciones una en base a metacrilato y otra en base a silorano. Metodología: 19 pacientes con LCNC hipersensibilidad, se distribuyeron en 4 grupos según el tratamiento: G1(n=31): Acido oxálico al 0,5% (Desenssiv, SSWhite)+Z250 (3MESPE); G2 (n=31): Acido oxálico al 0,5%+Filtek Silorane-P90 (3MESPE); G3 (n=30): Agua destilada+Z250; G4 (n=30): Agua destilada+Filtek Silorane-P90. Dos clínicos calibrados (kappa>0,75) evaluaron la sensibilidad de los dientes: Previo al tratamiento, a los 30, 60 y 90 días post-tratamiento mediante la escala VAS. Resultados: Los 4 grupos a los 30, 60 y 90 días redujeron la HS comparado con el baseline (p<0,05). G1 y G2 mostraron menor HS con G3 y G4 (p<0,05). Conclusión: Los 4 procedimientos restauradores reducen significativamente la hipersensibilidad, tanto a los 30, 60 y 90 días al comparar con el baseline.
