COMMUNITY DENTISTRY SCENARIO 2 (5) The World Health Organization has evaluated the prevalence of dental caries for the 12-year-olds. Data from recent studies show that the mean caries prevalence among 12-year-olds in Latvia, Lithuania, and Estonia was 5.8, 4.9, and 4.6, respectively. Absence of caries was recorded in 5% of Latvian and Estonian and 12% of Lithuanian 12-year-olds. Fifteen-yearold Latvians and Lithuanians averaged 8.1 and 7.0 DMFT, which, owing to the absence of radiographic examination, may be a substantial underestimation of real caries levels (exposure time). The possible adverse effects of the privatization of dental care and the benefits of increased access to fluoride dentifrice in these countries have not been evaluated yet. The extremely poor oral hygiene seen in epidemiologic surveys indicates that fluoride dentifrices may not be widely used (health system). The caries levels in the Baltic states resemble those commonly encountered a couple of decades ago in the Nordic countries (exposure time). SCENARIO 3 (9) According to a National Oral Health Survey report 2004, caries prevalence in India was 51.9%, 53.8% and 63.1% at ages of 5, 12 and 15 years respectively in different parts of the country. Available literature from 1940-1960 shows the prevalence of dental caries in India had a varied picture. This study was carried out to measure the caries prevalence and treatment needs in school children of 6-14 years of age residing in coastal areas of West Bengal (9). The overall caries prevalence in the permanent dentition was 28.06%. It was of 25.39% in boys and of 30.86% in girls (9). The Discussion sections mentions the comparison of these figures with other studies. A similar result was reported by Saravanan et al. in 2008. (10) They reported that the prevalence of caries in the permanent dentition was 26.5%. The prevalence of caries increases significantly with age in the permanent dentition. A very low level of dental caries was reported by (6, 7, 8). In 12 year-old school children in urban Kenya in 1984, a caries prevalence of nearly 22% and a 0.5 DMFT were reported by the author. Low caries prevalence was reported by Knutson in 1947. He reported the caries prevalence in 6-year-old children in Nicollet Country, Minnesota. The caries prevalence was 24.3%. In 1939 Sarkar examined 18,445 school children up to 16 years of
