We examined whether seeding a culture of long spinner periodontal ligament cells on the root surface is capable of creating new attachment. Premolars were extracted from a monkey and cells from the periodontal ligaments were cultured. The maxillary central incisors were extracted, the cementum and pulps removed and the root canals filled. After culturing the periodontal ligament cells on the planed root surface of the right central incisor, the tooth was maintained in a spinner culture for 4 weeks. The left central incisor, which was preserved without exposure to the cells, served as a control. The teeth were transplanted to their original sockets. After 6 week the seeded root surface was covered with fibrillar tissues. However, epithelial downgrowth, root resorption and ankylosis was observed in the control. These results indicate that this new technique may promote the formation of new connective tissue attachment.
