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 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.

OBJECTIVETo assess the dental caries prevalence of children in Yinchuan.

METHODSThe 3-, 5-, 12-, 15-year-old children were chosed from nursery, primary and middle schools of Yinchuan in 1990, 1996 and 2001. The survey was carried out by five senior dentists from stomatologic hospital of Yinchuan according WHO criteria. DMFT, DMFS and the ratio of tooth filled were counted.

RESULTSFrom 1990 to 2001, the prevalence of dental caries of 3-, 5-, 12-year-old children was degression (P < 0.01). But the prevalence of dental caries of 15-year-old children had no obvious change. The dental caries of small proportion of children were serious. The ratio of tooth filling was low.

CONCLUSIONWith the development of oral health education, the prevalence of dental caries of 3-, 5-, 12-year-old children in Yinchuan is descend. But the diagnosis, prevention and treatment should be strengthened, and the ratio of tooth filling should be increased.

OBJECTIVETo investigate the oral health status of undergraduate university students and to guide their oral hygiene behaviors.

METHODS3516 college students in Northwest University for Nationalities were investigated in this study according to the criterion issued by World Health Organization (WHO) on the basic methods of oral health investigation in 1997.

RESULTSThe caries prevalence rate among the students investigated was 47.87%. The average decayed teeth were 1.29. The obturation rate of caries was 20.42%. The students came from city showed significant higher caries rate than those from countryside, and so did the female students compared with the male students. Dental calculus rate was 79.78%. The dental segments related were 3.75. The worst situation was among male students and students from countryside. The examined rates were 53.30% of crowded incisor, 42.58% of maximum upper-incisor anomaly, 50.60% of the maximum lower-incisor anomaly and 31.09% of molar malposition, respectively. More rates of dentofacial anomalies showed no differences of significance between different area and gender.

CONCLUSIONIn general, the oral health status of the college students are not ideal. It is necessary to advocate early examination, early prevention and early treatment among the students in university.

OBJECTIVETo evaluate the differences in temperament between children with early childhood caries (ECC) and an age-matched children without ECC.

METHODSA total of 219 3-year-old children were selected in urban areas of Beijing, who were physically and mentally healthy. There were 109 children in ECC group, who had unfilled caries in 1 or more surfaces in primary maxillary anterior teeth, and 110 children without caries. The children were examined for ECC levels, and their parents were asked to complete the NYLS Temperament Scale questionnaire. Then the data was collected and analyzed.

RESULTSChildren with difficult, intermediate high or slow-to-warm-up temperament had more severe caries than children with easy or intermediate low temperament. There was a significant difference in temperament attribute "Activity level" between male children with ECC and without ECC. There was a significant difference in temperament attribute "Rhythmicity" between female children with ECC and without ECC.

CONCLUSIONSThere were some differences in temperament between 3-year-old children with ECC and without ECC in urban areas of Beijing.

OBJECTIVETo investigate dental caries polarization in 2-5 year-old children.

METHODS3 799 random samples of 2-5 year-old children from attending kindergarten in Shenyang were selected. Means of dmft index and SiC index for each age group were calculated by WHO Collaborating Center. The subjects of each age group were further divided into subgroups of different level of dmft: the dmft of subgroup I was 0, the dmft of subgroup II was 1, the dmft of subgroup III was 2, the dmft of sub-group IV was equal to or more than 3. The obtained data were analyzed statistically with SPSS 10.0.

RESULTS4.5% of 2-year-old children were carriers of 60.0% of the total dmft in that age group, 13.2% of 3-year-old children were carriers of 69.4% of the total dmft in that age group, 34.4% of 4-year-old children were carriers of 86.6% of the total dmft in that age group, and 47.8% of 5-year-old children were carriers of 89.8% of the total dmft of that age group.

CONCLUSIONThis study supports the assertion that a small percentage of persons with high dental caries rate and a large percentage of caries-free persons of early childhood caries.

OBJECTIVEThe aim of this survey was to obtain some information about the prevalence of deciduous tooth caries of 5-year-old children in Sichuan province.

METHODSBased on World Health Organization and national oral health survey standards, dental caries prevalence and treatment needs were investigated randomly in selected children of Sichuan province in 2005. And the differences between this survey result and the dental caries prevalence of 5-year-old children of Sichuan province in 1995 were compared.

RESULTSThe prevalence rate of deciduous tooth caries of 5-year-old children in Sichuan province was 58.72%. The mean number of dmft of 5-year-old was 2.77. The filling rate was only 2.32%. The prevalence rate and mean dmft of deciduous tooth caries showed no significant difference between different area and gender; but the children came from city showed significant higher filling rate than those from countryside, so did the female children compared with the male children. Compared these results with the dental caries of 5-year-old children in Sichuan province in 1995, the prevalence rate and mean dmft of deciduous tooth caries in Sichuan province in 2005 had no significant difference, but the filling rate decreased significantly.

CONCLUSIONThe deciduous tooth caries prevalence rate of 5-year-old children is still relatively high in Sichuan province; there remains a proportion of active untreated decays. The dental health care education to the parents and teachers should be emphasized. In order to get the earlier diagnosis and treatment, regular examination and prevention method should be conducted.

PURPOSE: This study was performed to investigate the effects of oral health education on kindergarten children. METHOD: The study was designed as a quasi-experimental, nonequivalent control group pre -post test design. Data was collected from April 1st to November 30th, 2001. The total samples were sixty seven healthy kindergarten children; the experiment group consisted of thirty three and the control group was thirty four children. The experimental group received an oral health education program daily for 20 minutes for four weeks. RESULT : There was significant improvements on oral health behavior in the experimental group. Streptococcus mutans and lactobacilli of the salivary variables in the experimental group were significantly higher than the control group. The dmft was lower in the experimental group than the control group, but there was no significant difference between the two groups. However it was significantly lower in the experimental group than control group over time. CONCLUSION: Oral health education for kindergarten children showed an increase in the use of tooth paste and practicing correct tooth brush usage. Also, it decreased the rate of eating cariogenic food and had a positive effect on oral health through suppressing dental cavities.
