E. Ostmanandersson et al., COMPARATIVE SEM STUDIES OF THE ENAMEL SURFACE APPEARANCE FOLLOWING THE USE OF GLASS-IONOMER CEMENT AND A DIACRYLATE RESIN FOR BRACKET BONDING, Swedish dental journal, 17(4), 1993, pp. 139-146
The enamel surface appearance after the use of glass ionomer cement an
d a diacrylate resin for orthodontic bracket bonding was compared in a
n in vivo test using scanning electron microscopy and an enamel surfac
e index system. Significant alterations in the enamel surface were fou
nd irrespective of the bonding procedure. The use of glass ionomer cem
ent resulted however in a somewhat less affected enamel surface compar
ed to the acrylate resin.
