Finished surface texture, abrasion resistance, and porosity of Aspa glass-ionomer cement. 1978

R Smales, and K Joyce

1. With the finishing agents tested Concise had a smoother surface texture than Aspa. 2. The smoothest surface was on Concise polymerized against a Mylar matrix strip. The smoothest surface for Aspa was obtained with a silicon carbide disk. 3. Aspa abraded about three times as rapidly by volume as Concise when tested by a two-body abrasion method. 4. Significantly more air bubbles were entrapped by hand mixing within Aspa than within Concise. 5. Controlled clinical studies of the glass-ionomer cements are needed before they can be fully evaluated as restorative materials.
