The literature currently available distinctly shows that fluoride varnish is superior to other delivery methods. Foams and rinses are yesterday's products. Varnish should be the topical fluoride of choice in your office. I understand the irony in painstakingly cleaning a patient's teeth, only to slop a sticky varnish on top of them and thus deprive the patient of that freshly polished feeling. Unfortunately, however, it's just the cost of doing business when you are providing fluoride using the most-proven delivery method available. Now, selecting the varnish to use is a different story. There are hundreds of choices on the market, and selecting one can be an exercise in trial and error. In my practice, I want a varnish that is easy to apply, has low viscosity, and dries clear.
All of those qualifications are met with Fluor Protector S from Ivoclar Vivadent Inc. Most varnishes deliver a very concentrated topical dose of fluoride. Delivered in either a multidose tube or a single-dose unit, Fluor Protector S is no different in that regard, but its chemistry offers a fairly novel concept when it comes to fluoride concentration. When Fluor Protector S is applied, the fluoride concentration is approximately 7,000 ppm. As the solvent dries, the fluoride concentration rises dramatically-to around 30,000 ppm. Also, it's a low-viscosity varnish that allows the varnish to flow into the interproximal spaces for the most benefit, unlike varnishes with higher viscosities, which can be difficult to spread over the exposed tooth structure. Like all other fluoride varnishes, it is indicated for use in patients with a high risk of caries, dental hypersensitivity, exposed root surfaces, and postoperative sensitivity.
