x-pur NaF varnish box

5% Neutral Sodium Fluoride


The #1 fluoride varnish used by public health in canada

Mechanism of action

White varnish works by increasing the concentration of fluoride in the outer surface of teeth, thereby enhancing fluoride uptake during early stages of demineralization. The varnish hardens on the tooth as soon as it comes in contact with saliva, allowing the high concentration of fluoride to be in contact with tooth enamel for an extended period of time (about 1 to 7 days). This is a much longer exposure compared to other high strength sodium fluroride products which are typically 10 to 15 minutes. The amount of fluoride deposited on the tooth surface is considerably greater in demineralized areas versus sound tooth surfaces. Thus, the benefits of fluoride varnish are greater for patients at high or moderate risks for caries or demineralization.

For best results, excessive saliva should be removed by blotting the tooth surfaces.
1. Treated teeth should minimally be "toothbrush" clean. A prophylaxis is not required.
2. Lift foil from the brush containing end. Once the brush is exposed, remove it from the tray. Peel back the remaining foil until the well containing the X-PUR varnish is exposed. Use the brush to move any varnish that has adhered to the foil into the well.
3. Use the brush to thoroughly mix the X-PUR varnish since components of sodium fluoride varnish may separate during storage.
4. Paint on a tiny layer of X-PUR varnish evenly to the areas being treated.
5. After application, have the patients pass their tongue over their teeth. X-PUR varnish will uniformly set to dentition in the presence of saliva. No rinsing or suctioning is required.
6. The minimal treatment for X-PUR varnish is 3 hours, preferably overnight.
7. Instruct the patient not to brush teeth or floss, to choose a softer food diet and to avoid hot fluids and alcohol containing products in order not to remove the applied varnish for at least 3 to 6 hours or preferably overnight.
