Share Abstract:

Marginal seal of a resin-modified glass-ionomer restorative material: An investigation of placement techniques


Pages: 729-732
PMID: 8935116

This study examined marginal seal of a visible resin-modified glass-ionomer restorative material. Class V cavity preparations in extracted human premolars were restored with one of four different placement techniques: bulk placement, vertical incremental placement, incremental placement with the gingival increment placed first, or incremental placement with the occlusal increment placed first. Either a cervical former or a hand instrument was used to contour the restorations. Measurement of dye penetration indicated that there was no statistically significant differences in microleakage among the groups, by placement technique or method of contouring. However, two groups contoured with a cervical former were found to be 100% leakage free.
