Abstract

Nonendodontically treated roots were submerged 1.5 to 2.0 mm. below the alveolar crest in three dogs. Twelve roots were treated in this manner. Regeneration of alveolar bone can be seen in three weeks with complete bone coverage in five weeks. A complete lamina dura can be seen around the amputated roots.

Bone failed to regenerate over two of the twelve roots. In one case there was delayed healing due to the early loss of some sutures. A sinus tract developed connecting the oral environment with the contents of the pulp. This led to bone resorption and a necrotic pulp. In another case the lack of bone cover led to external resorption of the amputated dentin.

Half of the cavities were filled with plaster of paris; the other half filled with blood. There is no evidence that plaster changes the rate of bone regeneration.

Histological examination after twelve weeks reveals regenerated bone with its osteoblasts; the regenerated periodontal membrane; and the cut surface of dentin with a layer of cementoblasts.
