Changes in caries prevalence in 7-12-year-old children from Araraquara, São Paulo, Brazil: 1989-1995

Abstract

The aim of this study was to compare the prevalence of caries in 7-12-year-old children from Araraquara, São Paulo, Brazil, in 1989 and 1995. Systematic random samples were drawn from the population of children enrolled in public schools. The surveys were carried out by trained examiners using the DMFT index and WHO diagnostic criteria. There was an increase in the percentage of children free of caries in the permanent dentition in all age groups (from 29 percent in 1989 to 51 percent in 1995). Amongst 12 year olds, the DMFT index was 3.8 in 1989 and 2.6 in 1995. Decreases were observed in the percentages of children classified in the 1-3 DMFT index category (from 40 percent in 1989 to 31 percent in 1995) and in the 4-6 DMFT index category (26.6 percent in 1989 to 16.5 percent in 1995). There was also a reduction in the percentage of children with a DMFT of 7 or more (4.4 percent in 1989 to 1.5 in 1995). The WHO/ FDI goal for the year 2000 of a mean DMFT index no more than 3 at the age of 12 years was achieved in this population, and on-going efforts should be made to reduce the percentage of children with caries in order to achieve the WHO/FDI goals for the year 2010.

“…11 This decrease has been also observed in the present study for the ages 12 and 18 years old, where there was a decrease in DMFT values at 12 year old around 32.3%, similar to that found in Araraquara, from 1989 to 1995. 3 In another study performed in a city (Bilac, Southeastern Brazil) without water fl uoridation, a 50.4% decrease in DMFT index was observed at 12 year-old children from public schools, 6 greater than the one found in the present study. According to WHO data (2003), dental caries experience has been increasing in the last years in most developing countries, in developed countries caries experience has decreased in the last 20 years.…”

“…Trata-se de tendência inversa ao que se tem observado em estudos epidemiológicos conduzidos em várias regiões do Brasil, nas quais os índices de cárie vêm apresentando tendência de queda ao longo do tempo (Dini et al, 1999;Freysleben et al, 2000;MS, 1996;Narvai et al, 2000).…”

“…No Brasil, as informações epidemiológicas disponíveis sobre ocorrência e distribuição da cárie são ainda muito limitadas, no que diz respeito tanto à cobertura geográfi-ca, como a tendências temporais. Usualmente, envolvem amostras urbanas, sobretudo de escolares (Dini et al, 1999;Freysleben et al, 2000;MS, 1988MS, , 1996Narvai et al, 2000;Normando & Araújo, 1990;Pinto, 1992;Viegas & Viegas, 1988).…”
