El objetivo de este estudio fue evaluar el destino que los dentistas de la ciudad de Juiz de Fora (Minas Gerais, Brasil) les dan a los residuos radiográficos que producen. Setenta y cuatro profesionales respondieron un cuestionario, con preguntas objetivas sobre el desecho de las soluciones reveladora y fijadora, de radiografías insatisfactorias para diagnóstico y de las láminas de plomo de los embalajes de películas intrabucales.
