Summary

The aim of this double-blind randomized controlled clinical trial was to evaluate the effect on dentin sensitivity using oxalic acid desensitizing agent before restoring with resin-based-composites, during one-year follow-up. One hundred and twenty two cervical lesions (31 patients, age range between 24 and 66 years) were selected and randomly divided into four groups: OA/Z250: treated with acid oxalic desensitizing agent (Desenssiv, SSWhite) before restoring with a methacrylate resin-based-composite (Z250, 3M ESPE), (n=31), OA/P90 treated with acid oxalic desensitizing agent (Desenssiv, SSWhite) before restoring with a silorane resin-based-composite (Silorane p90, 3M ESPE) (n=31), Z250 restored with methacrylate resin-based-composite (Z250, 3M ESPE) (n=30) and P90 restored with a silorane resin-based-composite (Silorane p90, 3M ESPE) (n=30). All lesions were evaluated at baseline, immediately and 1, 2, 3, 6 months and 1 year after treatment. Teeth sensitivity was measured by visual analog scale (VAS) after evaporation and tactile stimuli
