| Abstract;In three adult dogs, the dental root of the premolar of extraction was divided into small tips after freezing (-20.DEG.C., 3 months), and the tips were transplanted into own bone cavity of mandibular bone. Tissue specimens 1, 3 and 5 weeks after operations were made for observation under the light microscope. 1. In the case of the filling of frozen dental root tips, the osseous addition of frozen dental root tips was active 3 weeks after operation. These had been more active 5 weeks after, and frozen dental root tips were made up to bone by the absorption for replacement. 2. In the case of the own transplant of dental root tips immediately after extraction, compared with frozen dental root tips, osseous addition was similarly found at 3 weeks after operation. However matured bone trabeculae and progressed bone remodeling were found more clearly 5 weeks after. 3. We found no differences between bony interfaces on the frozen dental root tips and extracted dental root tips, and the ratios of bony interfaces were about 0% after 1 week, 54% after 3 weeks, and 73% after 5 weeks.
