Resumo
Objetivo: determinar prevalência, extensão, severidade e distribuição do desgaste erosivo (DE) em pré-escolares de Montevidéu.
Metodologia: estudo transversal de base populacional, amostra representativa de centros educacionais públicos e privados. Aspetos sociodemográficos, biológicos e comportamentais foram investigados por meio de questionário autorreferência pelos pais/responsáveis.Os exames foram realizados por dois operadores Kappa ≥ 0,7. DE foi registado com o Índice O´Brien modificado, relatando porcentagem e média; intervalo de confiança (IC) 95%. Foi realizada análise de associação com sexo e nível socioeconômico.
Resultados: 614 pré-escolares foram examinados. Prevalência: 57,6% (IC95%: 52,7-62,5). Extensão: 4,8 (IC 95%: 4,3-5,3). DE grave: 8,2% (IC 95%: 5,5-10,9). As superfícies mais afetadas foram palatinas dos incisivos superiores. Pré-escolares de alto nível socioeconômico apresentaram maior DE que os de baixo nível; 73,1% (IC 95%: 61,9-84,2) e 48,4% (IC 95%: 39,2-57,7) respetivamente (≤0,01).
Conclusões: a prevalência e extensão da DE foi alta. Esses dados podem contribuir em la modificação de medidas que visam controlar a prevalência de DE.
