Resumo
Os autores avaliaram a infiltração marginal com corante fluoresceina sódica a 2% em cavidades de classe V, localizadas no limite esmalte/cemento restauradas com cimento de ionômero vitreo; adesivo dentinário/resina composta e associação de cimento de ionômero vitreo forrador/adesivo dentinário/resina composta. Concluíram que apenas o cimento de ionômero vitreo restaurador Ma apresentou infiltração marginal estatisticamente significante.

Abstract
The authors evaluated marginal microleakage in class V restorations margins at the enamel/cementum junction. Microleakage was assessed by observation of a fluorescent dye penetration. The cavities were restored with glass ionomer restorative cement; with dentin adhesive/oomposite resin and with the association of glass ionomer lining cement/dentin adhesive/composite resin. This study indicates that only M6 glass ionomer restorative cement showed marginal microleakage statistically not significant.
