Appropriate regeneration of periodontal tissues is the primary purpose of periodontal disease treatment. The present study assessed the impact of three key regenerative elements—platelet-rich plasma (PRP), canine bone marrow mesenchymal stem cells (cBM-MSCs), and fibrin glue—on periodontal regeneration. In each of the study’s five dogs, Class II furcation defects were established on the buccal surface of five teeth. One tooth (five total) from each dog was placed into one of five groups: (1) PRP + fibrin glue, (2) PRP + fibrin glue + cBM-MSCs, (3) fibrin glue, (4) cBM-MSCs + fibrin glue, and (5) control (no treatment). Histologic and histometric evaluations were performed to assess the formation of new bone, cementum, and the periodontal ligament. Different types of new bone and cementum, the maximum thickness of new cementum and the periodontal ligament (PDL), the vitality of bone, and the presence of inflammation or foreign-body reactions were also elucidated. The histologic and histometric evaluations revealed substantial differences in all groups between the observed maximum thickness of newly formed cementum and PDL. The percentage of bone and cement formation drastically increased with the combined presence of stem cells, fibrin glue, and PRP. The results showed that the inherent regenerative capacity of periodontal tissues can be sufficient if their latent self-repair mechanisms are stimulated.
