Aim: This paper focuses on the 12 weeks clinical effectiveness of Vertise FlowTM, (VF) a proprietary self-adhering flowable resin composite, in comparison to other resin-based materials also suggested as hypersensitive agents and on an analytical study as a means to elucidate the mechanism of action.
Methods: The elemental composition of VF, Universal Dentine Sealant (UDS), a desensitize sealant, Clearfil Protect Bond (CPB), a self-etching adhesive, and Flor-Opal® Varnish (FOV), a fluoride-varnish, were investigated by using an X-ray energy dispersive spectrometer (EDX) in conjunction with a scanning electron microscope (SEM). Data was analysed by Anova test to obtain the percent of elemental components of each materials. Pain reduction in hypersensitive teeth was evaluated according to the Visual Analogue Scale (VAS), before the application of the materials, immediately after, and in 12 weeks of post-treatment. Clinical data was analysed with the Student’s t test for paired data, with a 5% significance level.
Results an amorphous layer with particle dispersed, which composition reflects silicon, ytterbium, alumina, phosphorus, calcium, barium, and fluoride formed the matrix of VF. Clinically, all the materials were able to reduce VAS, however, at 12 weeks VF and UDS showed the higher reduction followed by PB and FOV.
Conclusion: With the limit of this study, data are attributed to the capacity of VF to produce effective tubular seal in dental hypersensitivity in a consequence of its proper chemical components.
