Objectives: The aim of the present study was to investigate the clinical effectiveness over 12 weeks of Vertise Flow(™), a self-adhering composite, in dental hypersensitivity (DH).
Material and methods: The study was conducted as a split-mouth randomized clinical trial. Vertise Flow™ was compared to the following: (1) Universal Dentine Sealant, (2) Clearfil Protect Bond, and (3) Flor-Opal® Varnish. A total of 46 patients with 116 hypersensitive teeth were studied. Pain experience was generated by a cold stimulus and assessed using the visual analog scale (VAS) of pain. The response was recorded before the application of the materials (pre-1), immediately after (post-1), at 1- (post-2), 2- (post-3), and 12-week controls (post-4). Statistical differences in VAS were performed using the Kruskal-Wallis analysis at the different time-points (P < 0.05), adjusting statistical significances for multiple comparisons (Bonferroni correction).
Results: All the materials showed any statistically significant differences at the baseline. After the application of each material, a VAS decrease was demonstrated at every post-control. VF showed significant hypersensitivity reduction in post-1. Statistically significant relief was also observed in post-2 while no significant differences were detected in post-3 and post-4.
Conclusions: After 12-week controls, there was no statistically significant hypersensitivity reduction using VF in respect to the other materials. On the other hand, any significant differences were detected in the decrease of the VAS irrespective of the desensitizing agent employed at the 12-week controls.
Clinical relevance: The significant increase in VAS scores within the 12-weeks of environment suggested there is instability of VF when used as desensitizing agent.
