Abstract : [Abstract] The mandibular first and second molar buds from 4-day-old hamsters were transplanted in a subcutaneous space behind the ear of a young hamster of the same strain. The flank of each of the removed bell-stage molar buds was partially resected, the resected faces were joined, the first and second molar buds from the same jaw bound together with looped utility wax and then placed in the subcutaneous space. Some halved molar buds were also transplanted in the same manner. After 30 days of grafting the grafts were harvested, fixed and sectioned for histology. But some were observed macroscopically and prepared as ground sections. Dentin-union occurred between the two molars. No enamel-union was observed. Some of them had a common pulp cavity, whereas the remaining had a unfused pulp, respectively. Halved buds and some buds with a small resection which failed to fuse developed into a malformed tooth respectively, although the resected part which was imperfectly closed developed into a slit in the dentin through which the pulp cavity was connected to the periodontal tissue.
