Effect of different frequencies of fluoride dentifrice and mouthrinse administration: an in situ study

Abstract

The effect of a combination of topical fluoridation methods for inhibition of enamel demineralization in the face of a cariogenic challenge has not been clearly established. This in situ crossover study aimed to assess whether the addition of daily use of fluoride mouthrinse (FR) to that of fluoride dentifrice (FD) is equivalent to increasing the frequency of FD application in terms of the effect on enamel demineralization and fluoride content. Over 3 phases of 14 days each, 12 volunteers wore appliances containing enamel blocks exposed to a 20% sucrose solution 8 times/day. During each phase the blocks underwent one of the following treatments: 2x/day FD, 2x/day FD + 1x/day FR, and 3x/day FD. The blocks were assessed for hardness and fluoride content. Three x/day FD did not differ from 2x/day + 1x/day FR, however it enhanced demineralization protection when compared to 2x/day FD. All treatments produced an increase in enamel fluoride content compared to no treatment (sound blocks) (p < 0.05), but the differences between them were not significant. The results of this study suggest that the daily use of fluoride mouthrinse combined with that of fluoride dentifrice has similar effects on enamel demineralization and fluoride content when compared to increasing the frequency of fluoride dentifrice use.

Tooth Loss Prevalence and Risk Indicators among 12-Year-Old Schoolchildren from South Brazil

“…These significant associations were found even after the adjustment for other factors, including gingival bleeding, a proxy for biofilm control. Thus, it is possible to speculate that the beneficial effect of brushing frequency on tooth loss is associated with fluoride exposure as shown experimentally in a previous publication by our group [Souza et al, 2010].…”

Topical Fluoride for Preventing Dental Caries in Children and Adolescents

“…Common use involves rinsing the mouth with about 20 ml (2/3 fl oz) of mouthwash two times a day after brushing. The wash is typically swished or gargled for about half a minute and then spat out [108]. With regard to the capacity of fluoride present in the mouthrinses to react with dental enamel, fluoride bio-availability is linked not only to the concentration of fluoride salt in the mouthrinse.…”

Novel Agents for Prevention of Caries: A Review

“…X-PUR is recommended as a toothpaste application, but can also be used in medication carriers for longer exposure because it does not contain fluoride. 15,16 The other products containing NovaMin include a homecare toothpaste from Natural Health Organics (Oravive® Revitalizing Paste-5 wt%, which does not contain fluoride), prescription pastes for hypersensitivity marketed by 3M/Omni (SootheRx) and (Denshield® -both with 7.5 wt%), and a prophypaste promoted by Sunstar/Butler (NuCare® -100 wt% and water). Newer products include a tooth root desensitizer (Vitalmin -100 wt% NovaMin and water), a fluoride varnish (Durashield -10 wt% NovaMin and 5% NaF), and a dentifrice (Renew 5000 ppm fluoride and 5 wt% NovaMin).…”

So there should be individualized consideration of the underlying disease process is recommended for every patient and minimal intervention program can be considered for high-risk patients.…”
