Calcium hydroxide pulpotomy for primary teeth: a clinical study.

Calcium hydroxide pulpotomies were performed in 17 carious primary mandibular molars. Variables in the pulpotomy procedure were recognized and controlled in an attempt to obtain a more favorable result or end product. The effects of two methods of hemorrhage control were also evaluated. The duration of treatment for the study ranged from three to nine months. Treatment was clinically successful for all 17 teeth. The radiographic evaluations were more favorable for the experimental group than for the control group. Treatment was radiographically successful for 15 teeth, questionable for one tooth, and unsuccessful for one other tooth. The results of this study suggest that the aluminum chloride-calcium hydroxide pulpotomy may be a viable alternative to formocresol pulpotomies in the primary dentition. Although these findings encourage continued research, including a long-term follow-up, a histologic study is indicated.

Scanning x-ray microanalysis of root canal sealers.

Seven commercially available root canal sealer powders were analyzed by scanning x-ray microanalysis to identify constituent elements in each. Analysis showed that strongly cytotoxic sealers in vitro contained lead or magnesium, while those materials which exhibited mild or moderate cytotoxicity in vitro contained bismuth, zinc, calcium, or silicone.

Cytotoxicity evaluation of root canal sealers by the tissue culture--agar overlay technique.

Ten commercially available root canal sealers were tested for cytotoxicity by the tissue culture--agar overlay method for periods of 0, 24, 48, 72, and 96 hours. All sealers manifested evidence of toxicity at every stage of testing. Some sealers which were markedly toxic at 0 hour showed reducing levels of toxicity out to 96 hours. Others remained highly toxic throughout the entirety of the experimental period.
