“…The baseline fluoride concentration in dental plaque was similar to that reported by Tatevossian [1990] for areas with suboptimal tap water fluoride levels. In the present study, a twofold increase was evident 2 h after the intake, which is comparable to results observed in plaque fluid immediately after the use of a fluoride rinsing solution [Ekstrand, 1997;Sjögren, 2001]. This observation indicates that fluoridated milk can act as a potential source of fluoride to dental plaque and contribute to the cariostatic effect, both regarding its control of demineralisation and remineralisation properties of enamel [ten Cate, 1999] and by influencing cariogenic micro-organisms in dental plaque [Hamilton and Bowden, 1996].…”

This study determined fluoride (F) concentrations in whole saliva and dental plaque after intake of fluoridated milk using a randomised crossover experimental design. Eighteen healthy children (6–8 years) were subjected to each of four different 3-day drinking regimens: (a) 200 ml F-free tap water; (b) 200 ml tap water with 1.0 mg F; (c) 200 ml standard milk, and (d) 200 ml standard milk with 1.0 mg F. A washout period of 7 days was organised between the different drinking regimens. All children used F-free toothpaste prior to and during the trial and were instructed to avoid F-rich food and drinks. F concentration in unstimulated whole saliva was determined at baseline and after 15 and 120 min and in plaque samples at baseline and after 2 h. The mean baseline values ranged from 0.01 to 0.02 mg F/l in saliva and between 10.4 and 14.2 mg F/l in dental plaque. A statistically significant (p < 0.05) increase of F was disclosed in saliva 15 min after drinking F-containing milk and water (0.052 and 0.058 mg F/l, respectively). After 2 h, the salivary F^– concentrations were back to baseline values. In the plaque, however, a statistically significant (p < 0.01) twofold increase was found at 2 h after the intake of fluoridated milk and water, respectively. The results indicate that consumption of fluoridated milk contributes to a F storing process with significantly elevated F concentrations in dental plaque up to 2 h after intake. Further studies are required to determine the ‘therapeutic concentration’ of F in dental plaque after intake of fluoridated milk.

“…It has been proved that clearance of fluoride from the mouth is affected by salivary flow rate of an individual, swallowing frequency, and factors which aid in retention of fluoride in the mouth such as spaces between teeth and soft tissues, tooth structure, and surface coatings of hard and soft oral tissues [8,[14][15][16]. However, since we compared different methods in the same subjects, all these factors were probably almost the same during test period.…”

“…These fluoride levels in saliva are affected by the concentration of fluoride agent applied, amount of preparation, time since the exposure, and the method of delivery, which influence fluoride clearance and retention [6][7][8][9]. A variety of the fluoride products available for professional and self-application brings with it a need to assess their possible effectiveness, reflected in the plaque and salivary retention of fluoride.…”

The aim of the study was to assess salivary fluoride concentrations and ingestion of fluorides after five different techniques of topical fluoride treatment. Ten volunteers received applications of fluoride gel, toothpaste, and foam. Fluoride concentrations were determined using ion-selective fluoride electrode in the samples of unstimulated saliva before and after procedures. The amounts of fluoride applied, recovered from the mouth, and retained in the mouth were calculated for each treatment. It was proved that fluoride ingestion following tray application of fluoride foam was significantly lower than ingestion following tray applications of fluoride gel (p < 0.01). The use of limited amounts of fluorides on a tray resulted in similar fluoride retention and lower ingestion comparing to the method which involves a large portion of fluorides followed by rinsing. Tooth brushing resulted in high salivary retention rates per amount of fluorides used in the procedure. These data provide initial concept about the possible advantages of some methods of topical fluoride application over others.

“…This result was unexpected considering the fl uoride experiments in which no rinsing after tooth brushing increased the fl uoride content in saliva and plaque Sjögren and Birkhed, 1993;Sjögren, 2001;Sjögren and Melin, 2001;Issa and Toumba, 2004]. However, in those experiments, fl uoride was followed for no longer than 3 h. At those time points, the observed differences were very small and it may be questioned whether such differences would last for another 3 h. If so, it has to be realized that this does not necessarily hold true for amine and stannous cations.…”

The aim of this clinical study was to evaluate the effect of various rinsing protocols on oral acid production 6 h after tooth brushing with an amine fluoride/stannous fluoride (AmF/SnF₂) toothpaste. After a 14-day period of using F-free toothpaste, 30 participants followed three experimental protocols each, followed by F-free washout periods in a randomized crossover trial. They used AmF/SnF₂ toothpaste twice daily for 1 week, and after brushing, they either rinsed with tap water, omitted the post-brush rinse, or rinsed with an AmF/SnF₂ mouthwash. In the F-free washout periods, the participants brushed their teeth without further instructions. Six hours after the last brushing (± rinsing) of each period, subjects rinsed with 10 ml 10% sucrose solution for 2 min. A tongue film sample and a buccal plaque sample were taken 4 and 8 min after the sucrose challenge, respectively. Metabolic acid ions were determined by capillary electrophoresis. The results show that (1) omitting the post-brush water rinse did not reduce the production of lactic, acetic or minor acids in plaque, nor on the tongue, and that (2) the additional use of AmF/SnF₂ mouthwash after brushing reduced the acid production in plaque and tongue samples for at least 6 h. The distributions of acids produced in the plaque or tongue samples were not statistically different between experimental periods. It is concluded that an increase in the antimetabolic effect of AmF/SnF₂ toothpaste in between two daily brushing exercises is not achieved by omitting the post-brush water rinse. The additional use of AmF/SnF₂ mouthwash after brushing is effective in reducing the acid metabolism in dental plaque and tongue flora.
