RESUMEN
Objective @#To explore the effect of a community family doctor model on caries management for children aged 1 to 3 years in Wuhan, and to provide basis for community prevention and control of children’s caries.@*Methods@#Using stratified randomization and paired sampling, 1 000 children aged 1 to 3 years were selected from the core community of the Wuhan Donghu High-tech Zone. The trial group was followed up 4 times a year at home or in the clinic, and the control group was followed up only at the baseline and the endpoint (2 years later). Caries and caries status were examined at baseline and 2 years later, and brushing behavior was investigated by questionnaire. @* Results @#The prevalence/dmft in the test group and control group after two years were 15.8%/1.41 and 46.6%/3.25, respectively, and the difference was statistically significant. The frequency with which parents helped their children to brush in the test group improved significantly compared to that of the control group.@* Conclusion @#For children aged 1 to 3 years, the dental family doctor model of caries prevention is economical and effective, and its application and promotion are recommended.
RESUMEN
@#As one of the most common chronic diseases of the oral cavity, caries gradually accumulate over the lifetime and affect approximately 80% of the world population. The epidemiological characteristics of the disease are specific in terms of regional distribution, temporal distribution and population distribution. Caries prevalence and mean decayed, missing and filled permanent teeth (mean DMFT) scores are the most commonly used indexes in oral epidemiology. Caries prevalence is used to describe the frequency of caries over a certain period of time. In addition, DMFT scores reflect the severity of caries in the population. The caries prevalence and the severity of caries are assessed as part of a dynamic process. In developing countries, caries prevalence is higher among urban populations than among rural populations. Currently, the epidemic characteristics of caries in urban and rural areas are changing, and the caries prevalence of urban residents is lower than that of rural residents. This article is a chronological review of the Oral Health Epidemiological Surveys of China from 1983 to 2015, the Preventive Dentistry study and other related studies. It is concluded that the epidemic characteristics of caries in urban and rural areas in China have changed from a higher caries prevalence in urban areas compared to that in rural areas to a lower caries prevalence in urban areas compared to that in rural areas. Several factors, such as the dynamic development of differences in dietary habits, economic levels and access to oral medical resources of urban and rural residents might have led to changes in caries prevalence in urban and rural areas. The caries prevalence of rural residents has increased greatly, which indicates that the caries prevention efforts of the relevant departments should be focused more on rural areas in the future.
RESUMEN
@#The most common oral disease is the dental caries, which is chronic transmissible, losing of hard tissue of teeth, and is very widespread in the world. The annual report of oral health survey of World Health Organization shows that 60-90% of population of developing countries was affected by dental caries. In the press review, the prevalence of dental caries and mean DMFt score among 18 years old were 74.4% and 4.04 in Mexico, 2009; 87.4% and 3.59 in Australia, 2003; and 88.9% and 7.15 in Japan, 1999. In Mongolia, the prevalence of dental caries and mean DMFt score among military students in 1987 were 83.3% and 3.7. There is a few studies among students of School of dentistry. Study population consisted of 115 students, who studied from 3rd to 5th course of School of Dentistry, Mongolian National University of Medical Sciences. Study was done by cross sectional study design from November to December, 2017. We checked up dental status of all students according to recommendation by WHO, 2013. The study was approved by the Medical Research Ethics Committee of the Mongolian National University of Medical Sciences and informed consent was obtained from all students (2017/3-04). The prevalence of dental caries among all students was 100% and mean dental caries score was 8.3±0.3 DMF/t, 3.7±0.3 D/t, 3.8±0.3 F/t, 0.8±0.1 M/t. When we assessed mean DMF/t score by student’s course, it was 8.5±0.5 among 3rd year students, 8.6±0.7 among 4th year and 7.9±0.5 among 5th year (p>0.05). Mean decayed teeth among 3rd, 4th, 5th course students were 4.5±0.5, 4.1±0.6 and 2.8±0.4, respectively (p<0.05). Mean filled teeth was 3.4±0.5, 3.5±0.6, 4.4±0.4 (p>0.05) and missed teeth was 0.7±0.2, 1.0±0.3, 0.7±0.2 (p>0.05) among students respectively above courses. All students, who participated in our study had dental caries and observed declining the number of decayed teeth during the study and the number of filled teeth was increasing.
RESUMEN
The aim of this study to assess dental caries status and some growth indices among preschool children of Ulaanbaatar city, Mongolia. The study population consisted of 499 preschool children aged 3-5 years old randomly selected from 6 kindergartens of Ulaanbaatar city. The all children were examined oral examination and body weight and height by anthropometric methods. 1. The caries prevalence of all preschool children was 92.9%. The mean dmft and dmfs score were 8.2±4.8 and 11.7±8.6 of all children, 8.4±4.6 and 12.9±9.1 of 5 years old, 7.8±5.4 and 10.9±9.1 of 4 years old, 8.4±4.7 and 11.3±7.7 of 3 years old, respectively (p<0.01).2. The average body weight and height were 15.8±2.2 кg and 97.7±5.8 cm of 3 years old, 17.2±1.8 kg and 103.4±4.7 cm of 4 years old, 18.5±2.3 kg and 108.1±5.5 cm of 5 years old, respectively (p<0.001).The dental caries prevalence and mean dmft score among preschool children of Ulaanbaatar city were “VERY HIGH” stage, which is determined by criteria WHO. The body height and weight of preschool children of Ulaanbaatar city are increasing year by year. There is not observed significantly the relationship between dental caries status and body growth indices
