Objective: To analyze the morphology of dentin after application of desensitizing agents. Materials and Methods: Ten third molars were sectioned to obtain 2mm thick dentin disks and divided into 4 groups (n = 5): G0 – cut with a diamond disk, G1 – Colgate® Sensitive Pro-relief™ toothpaste; G2 – Duraflur® Fluoride varnish; G3 – biosilicate aqueous solution (Biosilicato®). After storage in dehydrated silica-gel (37°C/24h), the samples were placed on aluminum supports, coated with gold-palladium and observed under a scanning electron microscope. Post-treatment photomicrographs were obtained of the dentin. Results: In the G1 group the smear layer was observed; in the G2 and G4 groups, both the desensitizing agents and the smear layer and in the G3 group, a film of varnish. Conclusions: Different morphologies of dentin were observed after the proposed treatments for dentin hypersensitivity. |
