The storage of teeth before reimplantation in monkeys. A histologic study

This study is a histologic comparison of twenty teeth which were extracted, endodontically treated, stored for 7 days at +4 degrees C. and at -10 degrees C., and subsequently reimplanted in ten monkeys. In these monkeys, as controls, ten more teeth were extracted, endodontically treated, and immediately reimplanted. Up to 1 year, 100 per cent success was obtained in those teeth stored at +4 degrees C. before reimplantation, and only 50 per cent success was obtained in those teeth stored at -10 degrees C. before reimplantation.
