10 samples of Colgate dentifrice marketed in Vietnam were analysed in this study. The total fluoride content of each sample was determined by measuring the voltage of level-known standard solutions and that of sample test solutions, using Fluoride Selective Electrodes. The results revealed that total fluoride content of these samples is high, stable and not lower than level of 1,000 - 1,200 ppm in samples.

1. Fluor can reduce the progression of carious diseases when SMT> 3. While the index of permanent teeth carious of 12-year-old pupils in the North of Vietnam is 0.06, Fluor has no effectiveness to reduce the progression of carious to permanent teeth, it has effectiveness only to milk teeth, (SMT= 3.5) 3. There has been already one auxiliary dentist in primary school named Quang Trung in charge of dental hygiene education, regular scalling.. for school children these achievements do not however meet the expected results we actually need.

The project was carried out to examine the fluoride concentration of the natural water from northern provinces. The result of research will be applied on the Oro-dental Health care of children and community. 179 samples of water from 10 northern provinces were tested. The result of research showed that in almost of sources of water (97.8%) there is not enough fluoride. So the use of fluoride to prevent dental carries for children and community is necessary and urgent.

The research was carried out invitro to assess anticaries efficacy of toothpastes. 9 groups of enamel samples were treated with 9 kinds of toothpaste including 8 fluoride-toothpastes (marketed in Vietnam) and 1 placebo (no fluoride). The result of this study showed that fluoride-toothpaste had ability to increase fluoride component of the enamel so it has anticaries efficacy. But the different dentifrice’s anticaries efficacy was also different.

exposure during enamel formation. Increased and decreased in fluorosis prevalence may also reflect to the different ways of measuring the disease. The choice of measuring fluorosis is depends on the objective of the assessment such as assessing public health significant of fluorosis in the population or assessing the detailed of biological effects of fluoride. These differences in requirement have led to the adoption of many indices and assessment methods of enamel fluorosis, which subsequently led to evaluation of examiner agreement between them. Several indices were developed to measure dental fluorosis in the 20th century. These include fluorosis specific indices such as Dean’s Index; the Thylstrup and Fejerskov Index; the Total Tooth Surface Index; and the Fluorosis Risk Index. Non-specific descriptive indices such as the Developmental Defects of Enamel index have also been used to record fluorosis. Fluorosis has most commonly been recorded using clinical examinations and photographs. Recent developments have seen the use of a Visual Analog Scale and automated grading systems such as Quantitative Light Fluorescence emerge as possible enhancements to fluorosis scoring. This article aims to review existing indices and new methods in measuring dental fluorosis, together with examiner reliability across different methods and indices.

PURPOSE: This study aimed to investigate the correlation between the solubility and the amount of fluoride release when a resin surface coating agent is applied to RMGIC. MATERIALS AND METHODS: To measure the fluoride release and solubility, Fuji II LC®and Filtek™ Z350XT without a surface coating, Fuji II LC® with G coat plus™ and Fuji II LC® with Permaseal® were prepared. And the amount of fluoride release and solubility were measured. RESULTS: There was no significant difference in the daily fluoride release between the surface coating agents. The cumulative fluoride release was significantly different between the groups using RMGIC at 56 days (P < 0.05). In the solubility measurement, RMGIC without surface coating was significantly different only on the 7th day compared to the other three groups (P < 0.05). CONCLUSION: Surface coating agents can prevent the degradation of properties by the initial solvent in RMGIC. Therefore, fluoride is preserved inside the restorative material and the effect of surface coating after the addition is reduced, so that the effect on fluoride release and storage is also reduced.

In this study, sections of twenty eight teeth were used to investigate the effect of topical application of 8% stannous fluoride on the decalcification rate of enamel surfaces stripped in a manner suggested for orthodontic purpose. The enamel treated with a single application of a fluoride had a significantly lower tile rate of decalcification for the first 96 hours to lactate buffer solution. After double application of fluoride, decalcification rate decreased signicantly. This study suggested that the continuing protection of stripped surfaces should be sought by regularly scheduled treatment of the enamel with the topical application of fluoride and regular use of a fluoride containing dentifrice.

The study was carried out in vitro to determine the changes of fluoride concentration in tooth enamels that were treated with fluoride dentifrices. The analysis of enamels showed that the fluoride from dentifricaes has been delivered into tooth enamels to contribute to the process of remineralisation at the areas of demineralised enamels. So the fluoride dentifrices have efficacy in preventation of dental caries. The difference of fluoride concentration in enamel samples demonstrated that the anticaries efficacy of dentifrices was also different.
