Analysis of the use of Dycal with gutta-percha points as an endodontic filling technique.

The use of Dycal combined with gutta-percha cones as a permanent root canal filling material was analyzed. The following experiments were performed: 1. In vitro microscopic analysis of Dycal's adaptation in the dentin wall--gutta-percha cone interphase. 2. Study of the duration period of alkalinity. 3. Clinical and radiograhic posttreatment, inspection and evaluation, and follow-up. The results obtained in these studies showed: 1. There was correct adaptation and adherence of the material. 2. The alkalinity persisted up to 8 months after mixing. 3. There was clinically good postoperative tolerance. 4. Clinical and radiographic success was found in 90 percent of the cases in the treatment of normal vital pulps, vital inflamed pulps, and pulpless teeth with or without areas.
