Resumen


La fluorosis dental (FD) es un defecto del desarrollo del esmalte dental causado por la ingesta crónica y excesiva de fluoruro, que resulta en un esmalte hipomineralizado y poroso. Clínicamente se manifiesta desde manchas y delicadas líneas blancas hasta manchas opacas que cubren parte o toda la superficie del esmalte, el cual es susceptible a pigmentaciones o fracturas post-eruptivas. Sin embargo, establecer el grado de compromiso de los dientes no es una tarea fácil y para esto se han presentado índices que determinan el grado de severidad con mayor o menor detalle. Como la decisión de tratamiento está estrechamente relacionada a la gravedad del defecto, el objetivo de este artículo es presentar los aspectos clínicos de la fluorosis dental de acuerdo al Índice de Thylstrup-Fejerskov (1978). Los grados de severidad son representados de acuerdo con las características histológicas y las diferencias entre ellos son discutidas para que el odontólogo pueda diagnosticas correctamente y escoger el tratamiento más adecuado para el paciente con FD.


Aspectos clínicos da fluorose dentária de acordo com as características histológicas: revisão do Índice Thylstrup Fejerskov


A fluorose dental (FD) é um defeito de desenvolvimento do esmalte causado pela ingestão crônica e excessiva de flúor, resultando em um esmalte hipomineralizado com maior porosidade. Clinicamente é identificada como manchas que vão desde delicadas linhas brancas  até  manchas opacas que cobrem parte ou toda a superfície do esmalte podendo sofrer pigmentações ou fraturas após a irrupção. No entanto, a definição clínica do grau de comprometimento dos dentes não é uma tarefa fácil e tem sido apresentada na forma de índices que geralmente qualificam o grau de severidade com maior ou menor detalhes. Como a escolha do tratamento está intimamente ligada à gravidade do defeito, o objetivo deste artigo é apresentar os aspectos clínicos da fluorose dental representadas por meios do Índice de Thylstrup-Fejerskov (1978). Os escores de severidade são apresentadas de acordo com as características histológicas e as diferenças entre eles serão discutidas a fim de permitir ao dentista diagnosticar corretamente e escolher o tratamento mais adequado para o paciente com FD.
