比格犬自体牙移植的影像学和组织学观察
Imaging and histological observation of teeth autotransplantation in Beagle dog
摘要
Abstract
Objective To study the mechanism of periodontal tissue repair of transplanted tooth by analyzing the imaging and histological changes of autogenous transplanted tooth in Beagle dog.Methods For a 8-months-old beagle,the left mandibular premolar region was used as receptor region for autologous tooth transplantation of anterior teeth.X-ray examination was done after operation to observe the periodontal healing of transplanted teeth.Results X-ray at one month after operation showed that the No.1 tooth (left mandibular second premolar) has a narrowed periodontal gap,a small periapical radiolucency and external resorption at tooth neck;No.2 tooth (the left mandibular first premolar) has a internal resorption in the upper 1/3 root canal.Two-month post-operative X-ray examination indicated the periodontal healing of transplanted teeth was perfect.The external resorption of No.1 tooth enlarged and internal resorption of No.2 tooth remained the same.HE staining results showed that new fibrous bundle was formed at the root tip.A large number of lymphocytes and some plasmocytes exited at the tooth neck,pulp cavity and root tip.Conclusion Autogenous tooth transplantation can achieve good periodontal membrane healing.It is important to reduce the mechanical damage to tooth neck while pulling out the teeth.The timing of the dental pulp treatment after transplantation is one of the key elements to reduce postoperative complications.关键词
