Colldent debuts Phocal fluoride disks

Disks fight against interproximal caries.

LONDON, England--Colldent’s new Phocal fluoride disks provide dentists with ammunition in the battle against incipient interproximal caries.

Interproximal caries is a growing problem for dental professionals and patients—a problem with limited preventive treatment options. With Colldent’s Phocal disks, there is now an effective solution for preventing and treating interproximal decay.

The relatively high incidence of primary and secondary interproximal caries can be attributed to the failure of current home care and professional preventive agents from reaching these surfaces adequately. As a result, approximately 18 percent of interproximal surfaces develop caries, requiring the removal of much healthy tooth tissue for access in order to place restorations.

Furthermore, the interproximal margins at restoration-tooth interfaces often develop secondary caries after eight to 12 years, requiring restoration replacement.

The thin, round Phocal disks can be easily inserted between the teeth to deliver a concentrated dose of fluoride to previously inaccessible areas.

“Interproximal caries continues to be a frustrating problem for dental professionals,” said Dr. A. Jodaikin, Colldent’s chief scientist.

“We know that fluoride can prevent cavities, but the fluoride-containing products available today don’t effectively reach between the teeth. The Phocal disks were created to provide a simple, site-specific fluoride treatment when incipient interproximal caries is probable or detected, delivering the needed fluoride to prevent decay, arrest the progress of incipient caries and enhance remineralization at natural interproximal tooth sites and at tooth-restoration margins between teeth.”

Independent studies conducted at a Midwestern university research facility illustrate that Phocal disks provide superior fluoride uptake in the interproximal space when compared to fluoride tray gels, varnishes, and rinses.

The Phocal disks are available in two forms:

Phocal Apf (acidulated phosphate fluoride) disks contain 0.103 mg of sodium fluoride and .009 mg of hydrogen fluoride, induce an optimized low pH environment that cleans and etches tooth surfaces, and facilitate deep fluoride penetration while stimulating remineralization.

Phocal pHn (non-acidic sodium fluoride) disks are appropriate for patients with ceramic crowns or tooth-colored restorations. They contain 0.122 mg sodium fluoride, are less acidic and will not etch into ceramic crowns or restorations, and induce fluoridation and remineralization.
