Abstract

Background: Caries is a common and frequently occurring hazards to human health, although caries in our country on a downward trend, but still on an upward trend in caries incidence in rural and underdeveloped areas, dental caries is a common childhood diseases and frequently-occurring adversely affect one interested in the growth and development of children, and caries filling rate is very low, adult caries rate of approximately 50% caries rate of about 50% -70%. Dental caries in the majority of the crowd did not get effective treatment, resulting in caries incidence has been high in many developing countries due to lack of technology and the economy is relatively backward, these caries no effective treatment. In order to understand and solve the developing countries, especially in rural and underdeveloped areas of the incidence of dental caries status and treatment issues, mid-Frencken other scholars in the 1980s in Africa and Thailand, as a filling material using simple hand instruments and modified glass ionomer and sealers preventive treatment technology called atraumatic restorative treatment techniques (Atraumatic Restorative Treatment, ART), and formally proposed the use of the World Health Day 1994. ART technology is a non-invasive caries prevention and treatment techniques, involving the use of hand instruments to remove the softened completely caries demineralization of tooth structure, use of bonding dental materials filling cavities, and closed the presence of susceptible to the point gap caries pit and fissure, this filling operation is simple, does not require electric equipment, for the prevention and control of early caries significant effect. Studies have reported a success rate of ART technology filled permanent teeth sided hole high between 1991 and 1998, studies have shown that two-year retention rate was 92% -94%, Zimbabwe 1994-1997 and 1996-2000, single The surface hole field studies three years the highest retention rate of 88% -89%. The Thailand study reported that two-year success rate of 83%. So far observed the longest time of 6.3 years the filling body retention rate was 66%. Domestic permanent teeth caries findings of the clinical effects of ART treatment for six consecutive years: The sixth year small class Ⅰ filling retention rate was 75%, the class Ⅰ larger hole filling retention rate was 61%. Objective: To understand the Mongolian pupils permanent tooth caries prevalence differences with other ethnic groups, to better carry out the oral health care of minority children and youth, and explore suitable for China's rural and underdeveloped areas of caries prevention method. Methods: The study of all students in grades 1-6 of Chifeng City Keshiketengqi by Peng town four primary age children in the 7-14 age group a total of 832 caries epidemiological baseline survey, compare Mongolian children with other ethnic groups (Han main) caries incidence, and analyzed statistically. A total of 169 children were screened at the same time meet the the ART treatment standards and receiving ART restorative treatment, dental treatment and ART filling after 6 months, 12 months, 18 months and 24 months results were observed and were statistically Analysis. Results: Mongolian pupils permanent tooth caries rate in other ethnic pupils permanent teeth caries rate (P lt; 0.05), no significant difference in prevalence of dental caries between male and female students. Mongolian pupils DMFT higher than other ethnic pupils (P lt; 0.05), the DMFT was no significant difference between male and female students. The result of the comparison between the different time filling body failure rate: 6 months and 18 months respectively, the comparison between the 24-month failure rate P values ??were 0.044 and 0.007 (P lt; 0.05), the difference was statistically significance; between 12 months and 24 months, the failure rate comparison P values ??were 0.034 (P lt; 0.05), the difference was statistically significant. While failure rates between 6 months and 12 months, P = 0.417 (P gt; 0.05), no statistically significant difference; December, compared with the 18-month failure rate between P value of 0.184 (P gt ; 0.05), the difference was not statistically significant; comparison between 18 months and 24 months, the failure rate of the filling body P value of 0.348 (P gt; 0.05), the difference was not statistically difference. Conclusion: Chifeng the City Keshiketengqi by Peng town four primary Mongolian pupils caries higher than the region's other ethnic pupils. ART treatment after the review results show that with time, the success rate of the filling body gradually decline, the failure rate is gradually increased, ART treatment is not the best choice for permanent treatment, but the ART is a less invasive technology to reduce fear of patients, vulnerable children recognized and accepted, can be used in remote areas of early childhood oral health treatment (the recommended deciduous teeth treatment permanent teeth treatment is not recommended).
