Determine total fluoride content in Colgate dentifrices

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.

The orodental and dental hygiene in children with school age

The project was carried out to assess the situation of oral hygiene of the school children who have not been conducted oral hygiene as well as to access the effectiveness of dental education in the improvement of oral hygiene. The results of this study showed that: 1. The situation of oral hygiene of the school children is very bad. This is alarming situation of preventive hygiene. So we have to strengthen oral hygiene education for children community across the country. 2. The content of oral hygiene education of the school dental program for children (6-15 years old) has significant effectiveness on the improvement of oral hygiene. 3. The oral hygiene situation tightly related to orodental diseases such as dental caries, periodontal disease. So we have to conduct oral hygiene education for community in order to prevent dental caries and periodontal disease

The efficacy of dental care in the school age children in dental caries preventive program

The program of SCDC has been organised at all 25 primary and secondary schools of Gia Loc district since 1989-1990 to prevent dental caries for children aged 6 -15. The program’s activities include dental health education, conducting children to rinse their mouth by fluoride water 0.2% weekly and clinical preventation. After 8 years, the situatation of dental caries reduced. At age 12, the ratio of dental caries reduced 56.05% and DMFT reduced 79.41%. This result confirms that the contents of SCDC are suitble. Especially the situation of dental health shows that in 1997-1998 we reached WHO global goals and Vietnam goals for the year 2010.

Efficacy of dentooral care in school ages in the gingivitis prevention

The program of school-based oral care has been organised at all 25 primary and secondary schools of Gia Loc district since 1989/1990 to prevent oral diseases including gingivitis. After 8 years, the ratio of children who affected by gingivitis reduced clearly. The rate of school pupils who have acceptable gingival health increased from 8.42% to 94.21%. This result confirms that school-based oral preventive activities are neccesary and suitable. Particulary, in 1997/1998 we reached WHO and EEC countries’s goal as well as Vietnam’s goal for the year of 2010

On the efficacy of anticaries of Crest Toothpaste

An in-vitro study was conducted on tooth enamel collected in removed samples and processed with pH 5 demineralization solution and with the solution of Crest fluoride toothpaste. Fluoride uptake into demineralized enamel was measured. Result confirms the ability of Crest Toothpaste to prevent dental caries

Research on the change of fluoride component of the enamel structure under toothpaste's action

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.

Investigation on the concentration of fluor in natural water in North provincines of Vietnam

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.

Study on the urgent matter of school-based dental preventive program in Vietnam

The school-based dental preventive program has been developed strongly in many areas of the whole country. Especially, the program has been covered at level of province such as Ninh B×nh and Nam §Þnh. Its preventive results were very high. Dental caries were reduced and periodontal status is improved. Through the study of fluoride concentration in the natural water, we determine that the use of fluoride mouthwash for children at school is necessary to reduce dental caries.

contribution to evaluation of preventive quality of Colgate

The project was carried out to determine total fluoride on Colgate dentifrices. 10 samples of Colgate Dentifrices markerted in Vietnam were analysed. The total fluoride content was determined by measurement of solution voltage with fluoride Ionic Selective Electrode. The results of research showed that the total fluoride content on the above mentioned detifrices is high, stable and is not lower than level of 1,000-1,200 ppm.

Efficacy of school based orodental care in the prevention of periodontal diseases

The program of school-based oral care has been organised at all 25 primary and secondary schools of Gia Loc district since 1989/1990 to prevent oral diseases that include gingivitis. After 8 years, the ratio of children who affected by gingivitis reduced clearly. The rate of school pupils who have acceptable gingival health increased from 8.42% to 94.21%. This result confirms that school-based oral preventive activities are neccesary and suitable. Particularly, in 1997/1998 we reaches WHO and EEC countries’s goal as well as Vietnam’s goal for the year of 2010

School dental health care program - an effective solution of the teeth decay prevention and control

The program of SCDC has been organised at all 25 primary and secondary schools of Gia Loc district during 1989-1990 to prevent dental caries for children aged 6-15. The program’s activities include dental health education, conducting children to rinse their mouth by fluoride water 0.2% weekly and clinical preventation. After 8 years, the situation of dental caries reduced. At age of 12, the ratio of dental caries reduced 56.05% and DMFT reduced 79.41%. This result confirms that the contents of SCDC are suitable. Especially the situation of dental health shows that in 1997-1998 we reached WHO global goals and Vietnam goals for the year of 2010.

Impact of fluoride containing toothpaste in the enamel in vitro

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.
