NOVON® is a new, patented whitening compound that comprises hydrogen peroxide, urea and sodium tripolyphosphate (Reference to Technical Image; “Postulated Structure of NOVON”) and is the active ingredient in a new generation of tooth whitening gels.
NOVON® has a unique inherent feature in that, on application, it produces a “pH jump” into the alkaline pH range. This “pH jump” enhances the release of perhydroxyl ions for a faster whitening effect. (Reference to Technical Images; “Generation of the Perhydroxyl Ion” & “Diagram to Explain the Whitening Action of Perhydroxyl Ions”).
NOVON®-containing gels can therefore produce a similar whitening effect within a shorter time-frame, in comparison to whitening using a regular gel. Alternatively, within the same time-frame, a similar level of whitening can be achieved with a lower inclusion level of NOVON® (Hyland et al., 2014). This should be an advantage to patients with sensitive teeth.
In addition to the enhanced whitening effect, a further advantage of NOVON®-containing gels is their superior stability characteristics over a 24 month test period at a storage temperature of 2 – 24oC.
