Resumo: | Purpose: To assess the damage and the prevalence of caries and fluorosis in children and adolescents in the metropolitan area after 8 years of drinking water fluoridation and to compare them with the baseline study. Methods: This was a prevalence study. The sample was selected using two-step probability sampling and stratified according to socioeconomic level. Subjects included 2,323 schoolchildren aged 6 to 8 years and 12 years living within the metropolitan region. The parents of all students provided consent and were previously included in the study. The subjects were clinically examined by calibrated dentists, who used World Health Organization (WHO) screening criteria and indicators to determine the presence of caries and dental fluorosis. Results: No cavity damage was found in 23.68% of the children. The average dmft was 3.18 for children aged 6 to 8 years. The DMFT was 0.59 in children aged 6 to 8 years and 2.6 in children 12 years compared with the baseline study. These differences were statistically significant. There were also significant differences in the DMFT index for each socioeconomic status group. The average number of dams was higher among children of low socioeconomic status. Of the studied children, 14.3% of children had dental fluorosis. Fluorosis was very mild in 12.35% of the cases, mild in 1.98% and moderate in 0.26%. There were no cases of severe fluorosis (classified according to Dean's index). Conclusion: We conclude that after 8 years drinking water fluoridation in the metropolitan area, the number of children with no history of caries has increased by approximately 100%. The number of cases significantly affected by caries has also decreased significantly. The incidence of dental fluorosis has increased, but to milder degrees. |

Metodologia: Desenho: estudo de prevalência. A amostra probabilística, estratificada por nível socioeconômico, constituiu-se de 2.323 escolares de 6-8 e 12 anos na Região Metropolitana. Todos os alunos foram clinicamente examinados por dentistas calibrados, utilizando critérios de seleção e indicadores propostos pela OMS para determinar cárie e fluorose dentária. Resultados: Cerca de 24% das crianças estavam livres de cáries. A média de CPOD foi de 3,18 em escolares de 6 a 8 anos. O CPOD foi de 0,59 em crianças de 6 a 8 anos e de 2,6 em crianças de 12 anos em relação ao estudo de base, sendo essas diferenças estatisticamente significativas. Houve diferenças significativas devido ao nível socioeconômico, sendo que os valores médios foram maiores em crianças de baixo nível socioeconômico. Cerca de 14% das crianças apresentaram fluorose dentária, em geral de grau muito leve. Conclusão: Após 8 anos de fluoretação da água potável na região metropolitana, observou-se um aumento de 100% de crianças sem história de cárie e significativa diminuição de danos. A fluorose dentária aumentou, mas em graus mais leves.EDIPUCRS - Editora Universitária da PUCRS2011-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlecross-sectional studyestudo transversalapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/8133Revista Odonto Ciência; Vol. 26 No. 2 (2011); 109 - 115Revista Odonto Ciência; v. 26 n. 2 (2011); 109 - 1151980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/8133/6498Yevenes, Ismael HenryZillmann, Gisela CarmenMuñoz, Andrea PaulinaAranda, WaldoEcheverría, SoniaHassi, JoséMaass, PaulaSalazar, Marliinfo:eu-repo/semantics/openAccess2013-11-11T12:02:46Zoai:ojs.revistaseletronicas.pucrs.br:article/8133Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:02:46Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
