| Research Abstract |
The aim of the present study was to evaluate the effect of a novel bone swaging (BS) approach combined with injectable calcium phosphate bone cement (CPC) on periodontal healing in 1-wall intrabony defects in dogs. 1-wall intrabony defects were surgically created on the distal and mesial sides of bilateral mandibular fourth premolars in beagle dogs. The defects were treated with BS alone, CPC alone, BS with CPC (BS/CPC) or sham-surgery (OFD). The animals were euthanized for histologic evaluation at 8 weeks. In the BS/CPC group, new bone formation was noted extending from the host bone crest toward the coronal region of the defects, compared with the other groups. 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.
