effect of micro abrasion on surface topography of enamel and esthetic restorative materials

ABSTRACT

The effect of Prema microabrasion compound on enamel, composite, compomer, and glass ionomer was tested. Glass ionomer recorded a significantly higher average roughness than all other materials tested, that ranged between 2.7 mm [FUJI ILL C] and 3.2 um [Vitremer]. It was concluded that enamel microabrasion seems to be unsatisfactory for esthetic restorations with emphasis to roughness topography
