Interproximal caries presents a continual clinical concern.
The purpose of this study was to evaluate the ability of fluoride-releasing materials to remineralize incipient caries lesions on adjacent teeth, at the interproximal site with and without exposure to a fluoridated dentifrice. Thirty additional teeth had 1 x 5 mm artificial caries lesions formed at the interproximal contact point. The sections had varnish placed, leaving only the external section site exposed, and were situated back into the original tooth. These teeth were then mounted with the artificial lesion having an interproximal contact with the adjacent tooth restoration. All teeth were cycled through an artificial caries system for thirty minutes, three times per day.
