Dimensional stability of reversible hydrocolloid impressions immersed in selected disinfectant solutions.
Full-arch reversible hydrocolloid impressions of a dentoform arch (Columbia) containing an extracted first premolar prepared for a distal-occlusal inlay were immersed for 30 minutes in selected disinfectant solutions. The impressions were poured with die stone, and three cast inlays were fabricated on each die. The results of this procedure indicate that a 30-minute immersion of reversible hydrocolloid impressions in diluted solutions of iodophor, commercial hypochlorite, or 2% acidic glutaraldehyde does not adversely affect the dimensional stability of these impressions.
