The study groups using a dentifrice and mouthrinse both containing fluorides, a dentifrice containing stannous fluoride and a mouthrinse containing sodium fluoride, or a mouthrinse containing sodium fluoride with a placebo dentifrice had a 20.7% to 29.0% lower DMF increment than the control group after 30 months. These differences were significant. The study groups using a dentifrice containing amine fluorides and a placebo mouthrinse, a mouthrinse containing amine fluorides and a placebo dentifrice, or a dentifrice containing stannous fluoride and a placebo mouthrinse had a 13.6% to 22.4% lower DMF increment than the control group. These differences were not statistically significant. There was no significant difference in effectiveness against caries between the use of the organic or inorganic fluoride products. Recent studies have shown a high fluorine uptake in the enamel and a considerable caries reduction following the application of varnished containing fluoride. As the application is easy to carry out it may in certain situations serve as an alternative to other topical fluoride school programmes. The aim of the present study, therefore, was to compare the caries increment in schoolchildren exposed to a fluoride varnish (Duraphat) every six months and in children receiving the conventional weekly fluoride mouthrinsing programme with 0.2 per cent sodium fluoride over a two-year period. Two hundred 14-year-old children, divided into one test and one control group took part in the study. They were clinically and radiographically examined every year. Preexperimental data revealed no differences between the groups. During the experimental period the children in the fluoride varnish group developed a statistically significant lower number of new carious lesions compared with those in the mouthrinsing group. The difference in caries increment was about 30 per cent. Further clinical studies to compare the effects of various topical fluoride programmes are recommended. The purpose of this study was to evaluate the separate effect of fluoride dentifrice, fluoride mouthrinsing and fluoride varnish on approximal dental caries. All 252 13-14-yr-old children at an elementary school were selected at random and divided among four groups for a 3-yr longitudinal study. Group 1 received a fluoride dentifrice for home care and a fluoride mouthrinse once a week. Group 2 received a fluoride dentifrice for home care and a placebo mouthrinse once a week. Group 3 received a fluoride dentifrice for home care and a fluoride varnish once every 3 months. Group 4 received a placebo dentifrice for home care and a fluoride rinse once a week. Fluoride rinsing did not give any additional effect compared with placebo-rinsing when a fluoride dentifrice was used for home care. Fluoride varnish gave a significant caries reduction compared with fluoride rinsing. The aim of this trial was to compare the caries-preventive effect of sodium fluoride varnish and acidulated phosphate fluoride (APF) gel. A total of 254 children aged 12-13 years with high past caries experience were randomly divided into two groups. The participants received semi-annual applications of either fluoride varnish or APF gel for 3 years. During the study, the mean (+/- SD) total DMFS increments of the varnish and gel groups were 6.8 +/- 5.6 and 7.7 +/- 6.4, respectively, when initial caries was included, and 3.1 +/- 3.7 and 3.6 +/- 4.6 when initial caries was excluded. The difference was most evident on the approximal surfaces (varnish: 1.4 +/- 2.4; gel: 1.9 +/- 3.1). However, this difference was not statistically significant. Although larger studies are needed for firm conclusions about the comparative effect of the two fluoride measures, the results suggest that fluoride varnish is as effective as fluoride gel at least in preventing approximal caries. Taking into account the shorter treatment time, using fluoride varnish for professional applications seems justified. This study compared caries inhibition in children by an amine fluoride and an acidulated phosphate fluoride when administered in a topically applied gel. In addition, the effects of applying amine fluoride daily and weekly were compared. Four hundred and sixty-eight children, ages 6 to 13, were randomly assigned to one of five treatment groups and received a total of five, 5-minute treatments. The treatment and interval between each of the five treatments were as follows:(A)acidulated phosphate fluoride daily, (B) amine fluoride daily, (C) amine fluoride weekly, (D) placebo daily, and (E) placebo weekly. When the children were examined for total Decayed, Missing, and Filled Surfaces (DMFS) increments 2 years later, no significant differences were observed. However, when the data were examined for effects of DMFS for specific tooth surface, significant restriction (61%) of occlusal increment was shown in the group which was treated with amine fluoride daily for 5 consecutive days as compared with the control group. 751 14- and 15-year old children completed a 3-year, double-blind, caries preventive program. The effects of daily, supervised toothbrushing with an 0.76% sodium monofluorophosphate dentifrice, rinsing with a 0.05% sodium fluoride mouthrinse, and the combined effects of the two treatments were investigated. Both the dentifrice and mouthrinse reduced the incidence of dental caries, but their combined use at the same time had no greater effect than either used alone. The effect of reducing the abrasivity of toothpaste on dental caries was observed in a 3-year clinical trial involving 1106 11-13-year-old Berkshire schoolchildren were divided into three groups; Group 1 were allocated a low abrasivity paste containing 0.8% sodium monofluorophosphate, Group 2 a paste of conventional abrasivity also containing 0.8% sodium monofluorophosphate and Group 3 a low abrasivity non-fluoride paste. After 3 years the net DMFS increments (clinical and radiographic scores combined) were 4.22 in Group 1, 4.72 in Group 2 and 6.43 in Group 3. The differences between Groups 1 and 3 and between Groups 2 and 3 were highly significant (P less than 0.001). The mean increment in Group 1 was lower than in Group 2 but did not reach statistical significance. Reducing the abrasivity of the toothpaste had no meaningful effect on the standard of oral hygiene and prevalence of gingivitis as measured by the Gingival and Plaque Indices. In this double-blind trial, the anticaries effectiveness of a test toothpaste formulated for young children with 550 ppm F was compared with that of a positive control toothpaste containing 1055 ppm fluoride. More than 3000 2-year-old children were enrolled in the study and after 3 years of toothpaste use, 2177 (72 per cent) were examined. From a clinical and radiographic assessment, more than half the children were found to be caries free and only 32 (1.5 per cent) had evidence of rampant caries. There appeared to be little or no difference between children who had used test or control pastes, either in caries or in plaque levels. On the basis of this clinical trial the experimental toothpaste with 550 ppm fluoride would appear to have a similar anticaries efficacy to that of the control toothpaste. Differences were seen in relation to sex of the child and to social class. Girls had lower levels of plaque than boys but more carious teeth. Children from families in higher social classes had fewer carious teeth and lower levels of plaque. The aim of this study was to assess the caries incidence and plaque accumulation in schoolchildren at caries risk, after brushing the teeth fortnightly with gels containing 0, 0.4% F, 1.25% F as amine fluoride (AmF) or the common amine fluoride toothpaste containing 0.125% F. The study was conducted double blind over an 18-month period, and after 6 months discontinuation of brushing. Only the group that brushed with the 1.25% AmF gel showed a significant decrease in caries development compared to the group that brushed with the 0.125% AmF toothpaste. During the 6-month discontinuation period, the incidence of caries increased in all groups; the differences in caries development between all groups were not significant. Plaque indices were significantly lower in the AmF-treated groups. The highest fluoride concentration in the gel reduced the development of caries to zero, probably due to increased fluoride levels in the oral milieu of caries risk children. In order to maintain a positive effect of fluoride over an extended time period, caries-prone subjects should continue an initiated fluoride programme. The effect of sodium fluoride varnish (Duraphat) applications on proximal caries progression was studied during a 3-yr period in 87 teenagers and compared to a control group (n = 107). In the fluoride varnish group the children were treated with fluoride varnish every third month during the experimental period. Caries lesions on the mesial surfaces of first premolars to the mesial surfaces of second molars were recorded annually on radiographs and an individual progression value was calculated. The study showed that topical application of fluoride varnish every third month significantly (P less than 0.05) reduced the progression of proximal caries lesions in premolars and molars. The most obvious reduction of caries progression was observed among children who developed between two and eight new proximal lesions during the test period. In the children with the highest caries activity (greater than nine new proximal lesions) Duraphat treatments did not significantly reduce proximal caries progression in premolars and molars. A 3-year clinical trial was carried out in France just after fluoride toothpaste was allowed to be sold on the mass market. The aim was to assess the caries preventive effect of a toothpaste containing the maximum fluoride level permitted by the EEC (1.2% SMFP). The trial started with 1318 10-12-yr-old children from a wide socioeconomic background in a typical French community. Test toothpaste was given to 659 children whereas the remaining 659 children obtained the same toothpaste without the fluoride additive. The brushing was unsupervised and performed by the children at home. Dental caries was assessed by clinical and radiographic examinations. 1061 children completed the trial. An interview carried out at the final examination identified a group of 116 uncooperative children (less than five brushings a week on average) who were not included in the statistical analysis. The following mean reductions were found: 26% for DMFT, 27% for DMFS, and 39% for DMFSU. The DMFS index for approximal, buccal-lingual and occlusal surfaces showed caries reductions of 32%, 25%, and 22%, respectively. The trial demonstrated a highly significant effectiveness of the 1.2% SMFP toothpaste in a French population. The caries prophylactic effect of semi-annual applications of a fluoride-containing varnish (Duraphat) was tested in 121 15-year-old children. The children were divided into a test (60 subjects). The teeth of the children in the test group were coated with fluoride varnish at the beginning of the experimental period and again 6 months later. A clinical and radiographic examination of all children was performed immediately prior to the first application of varnish and 1 year later. The mean caries increment was 0.9 new DMFS in the test group and 4.0 in the control group. The difference was statistically significant at the 0.1% level. The caries prophylactic effect on different tooth surfaces was statistically significant both on proximal and on occlusal surfaces at the 0.1% level. Analyzing the material with respect to the caries prophylactic effect against the background of caries prevalence at the start of the investigation showed a better effect in the group of children with low and medium initial DMFS values. The aim of this randomized, double-blind study was to measure the cariostatic effect of Bifluorid 12 (VOCO GmbH), containing 6% sodium fluoride and 6% calcium fluoride and Laweflour-Schüttellack (LAW), containing 5% sodium fluoride in comparing of placebo varnish. The caries study included 400 schoolchildren, aged 12-14 years. The tests according to the DMFS were carried out by two independent examiners. The 400 children were divided into 3 test and 1 placebo group, each group consisting of 100 subjects. After two years there was a significant inhibition of caries increment in all test groups compared to placebo group. Percentage caries reduction ranged from 25 to 30%. The highest effect was stated at proximal surfaces. A randomized, double blind clinical trial of the caries inhibition effects of dentifrices containing respectively monofluorophosphate and amine fluoride was performed. A third control group used a toothpaste without fluoride. A total number of 2008 schoolchildren ranging in age from 6 to 8 years and living in Strasbourg (France) participated in this study. After a baseline examination three groups were constructed with the block randomization technic. The caries inhibition effects of the three dental pastes were compared after 3 years of unsupervised use. The monofluorophosphate dentifrice showed a reduction of 7.02% for DMFT, 5.17% for DMFS and 25.26% for the df rate. The reduction of amine fluoride dentifrice caries was respectively 21.62% for DMFT, 20.94% for DMFS and 48.66% for the df rate.
Fluoride toothpastes in comparison to mouthrinses or gels appear to have a similar degree of effectiveness for the prevention of dental caries in children. There is no clear suggestion that fluoride varnish is more effective than mouthrinses and the evidence for the comparative effectiveness of fluoride varnishes and gels, and mouthrinses and gels is inconclusive. No conclusions about adverse effects could be reached, because no data were reported on in the trials. Acceptance is likely to be greater for fluoride toothpaste.
