Effect of a Self-adhering Material in Dental Hypersensitivity

Aim: To compare the desensitizing capacity of Vertise Flow™ (VF), a new self adhering material, in the treatment of dentine hypersensitivity (DH) in patients who are xerostomic due to radiotherapy for head and neck cancer. Methods: A total of 17 patients were selected for the study. The study was conducted as a split-mouth randomized clinical trial comparing: 1) VF 2) Universal Dentin Sealant (UDS), 3) Clearfil Protect Bond (CPB) and 4) Flor-Opal® Varnish (FOV). Basal and stimulated salivary flow was recorded for each patient according to the method described by Sreebny. The pain experience was generated by a cold stimulus directly to a sensitive tooth surface and assessed using the Visual Analogue Scale (VAS). The response was recorded before the application of the materials (PRE-1), immediately after (POST-1), at 1-week (POST-2), 4-weeks (POST-3) and 12-week controls (POST-4).
