Comparison of Three Toothpastes for the Prevention and Reduction of White Spot Lesions

During the course of orthodontic treatment, the practitioner normally faces two common iatrogenic treatment side effects: root resorption and enamel decalcification, with the latter occurring at a much higher frequency. While the processes that lead to enamel demineralization are understood, methods to diminish or perhaps eliminate degradation of enamel surfaces are being searched for. Several approaches have been formulated to counteract demineralization of tooth structure. One approach involves patient compliance and consists of in-depth oral hygiene instructions, in-office fluoride applications, and at-home fluoride rinses, gels, and varnishes. An alternative approach, which possesses potential benefit regardless of patient compliance, includes the use of fluoride-releasing agents, such as composites, glass ionomers, sealants, and elastomeric ties.

Enamel decalcification or white spot formation, is a phenomenon occurring primarily on smooth enamel surfaces of teeth, notably within the gingival third of the crown. Demineralized enamel, the precursor to caries formation, can be attributed to fixed orthodontic appliances, and prolonged exposure to bacterial plaque. Bacterial plaque promotes the accumulation of acidic byproducts and demineralization that leads to successive changes in the optical properties of subsurface demineralized enamel. Progression to clinically detectable white spot lesions may occur as early as one month following the placement of orthodontic appliances.

Two new anti-cavity toothpastes, Clinpro™ 5000 with 1.1% Sodium Fluoride and Clinpro™ Tooth Crème with 0.21% Sodium Fluoride, are currently available and have been shown in some initial case reports to be useful in the reduction of white spot lesions. Clinpro™ restores minerals and helps you produce saliva. Both the Clinpro™ products are advanced formulas containing an innovative tri-calcium phosphate ingredient. They are available exclusively from 3M ESPE. Clinpro™ contains fluoride as well as calcium and phosphate, which are components naturally found in saliva.

Thus, this study will compare Clinpro™ 5000 1.1% Sodium Fluoride Anti-Cavity Toothpaste, Clinpro™ Tooth Crème, and MI-Paste Plus for the prevention and reduction of white spot lesions during orthodontic treatment.
