Abstract
Gelatin (denatured collagen), assumed to be a periodontal membrane, was insolubilized by glutaraldehyde in solution. DTA and IR analyses showed that gelatin can be insolubilized well by a glutaraldehyde solution. Gelation of 10wt% concentration had a maximum value of adhesive strength at the composite resin surface which was virtually independent of the type of commercial composite, although it depended strongly on the surface roughness. The adhesive strength in solution at 37℃ decreased to one-tenth in air, and was maintained for at least 2 weeks. A glutaraldehyde concentration below 5% was the most effective, but it was expected a treatment time longer than 1 hr would be required.
