Effect of bone swaging with calcium phosphate bone cement on periodontal regeneration in dogs

Objectives. The present study evaluated the effects of bone swaging (BS) with injectable calcium phosphate bone cement (CPC) on periodontal healing in 1-wall intrabony defects in dogs. Study Design. Surgically created 1-wall intrabony defects were treated with BS, CPC, BS with CPC (BS/CPC), or open-flap debridement (OFD). The animals were humanely killed for histologic evaluation at 8 weeks. Results. New bone formation occurred from the host bone toward the coronal region of the defects in the BS/CPC group. The height of new bone formation was significantly higher in the BS/CPC group than in the other groups (P < .05). New cementum formation was most notable in the BS/CPC group, where it was significantly greater than in the OFD and CPC groups (P < .05). Conclusions. Within the limitations of the present study, it was concluded that BS/CPC treatment effectively promoted new bone and cementum formation in 1-wall intrabony defects in dogs.
