PBCP生物陶瓷修复比格犬牙周骨缺损的组织学观察

he purpose of the present study was to evaluate healing of surgically-created labial alveolar bone dehiscence following treatment with or without porous biphasic calcium phosphate (PBCP) in Beagle dogs. Alveolar bone dehiscences were surgically created bilaterally at the labial aspects of maxillary third incisors in twelve beagle dogs. After root conditioning, PBCP were filled in defects and contralaterals were put nothing. Beagle dogs were killed at the 3 months. Histological observations were processed through light microscopy. The results revealed the healing in PBCP groups evidenced a new attachment apparatus and that in the control groups demonstrated a long junctional epithelium. There was always much more bone fill in PBCP groups compared to the control groups in the same dog. In this study, PBCP had proved to work well as a bioactive and osteoconductive scaffold material to promote periodontal regeneration effectively.
