Desensitizing Efficacy of Polymeric Nano Calcium Fluoride Containing Varnish

Desensitizing Efficacy of Polymeric Nano Calcium Fluoride Containing Varnish Versus Casein Phosphopeptide Amorphous Calcium Phosphate Containing Fluoride Varnish: Randomized Clinical Trial

The aim of this study is to evaluate the Desensitizing efficacy of polymeric nano calcium fluoride containing varnish and its implementation into clinical practice.

Increasing the demand to find a desensitizing agent that should be biocompatible, easy to apply, painless, not changing the dental color, fast onset, and maintain a long-term effect gives a highlight to the patented formula of the polymeric nano calcium fluoride which newly introduced into the practice .

OliNano SEAL is an innovative "varnish-like" protector based on a patented silicone polymer with a true nano technology that provides an exceptional adhesion to enamel and dentin without prior etching for approximately 12 months (other available products max. 2-3 months).

It consists of four components Silicone polymer provides excellent adhesion to enamel and dentine, with transparent formula. NANO-fluoroapatite flows into enamel micro cracks & seals it, penetrating into the dentinal tubules closing them eventually. As for the NANO-calcium fluoride it behaves as a fluoride reservoir, provides gradual and long-term fluoride release. The fourth component Amine fluoride (Olaflur) provides immediate fluoride ion release and accelerates natural remineralization.
