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

Abstract

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.
