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.

[EN]The geometry and the hydraulic conductivity of the unsaturated zone is difficult to study from traditional techniques, like samples from trenches that normally provide surficial data or boreholes, that are expensive and provide local information. Non-destructive geophysical techniques and among them the electrical resistivity tomography method can be applicable in volcanic areas, where the lava flows and pyroclastic deposits have a wide range of values depending on the degree of fracturing and weathering of lava flows, and porosity and texture of the pyroclastic deposits. In order to characterize the subsurface geology below the golf course of Bandama (Gran Canaria) has conducted a campaign of electrical resistivity tomography profiles.
