The clinical study from Italy examined the effectiveness of dental varnishes on sensitive teeth. Ninety patients affected by sensitive teeth were divided into three groups and treated with one of the following protocols:
The sensitivity of the teeth was established at the beginning of the study, in other words, at baseline, and then again after 30 and 90 days using the Schiff scale. The results were clear-cut: The tooth hypersensitivity which existed in all the groups at the beginning of the study decreased substantially and statistically significantly for a least 90 days in the groups that were treated with the protective varnishes Fluor Protector S and Cervitec F. The patients who were given the placebo did not show any improvements.
The Cervitec F varnish system contains fluoride, chlorhexidine and cetylpyridinium chloride (CPC). This innovative combination of ingredients offers protection for sensitive teeth and it provides fluoride and controls germs all in one step.
