ABSTRACT
Objective:
To test the periodontal regeneration potential after tooth root replantation combined with in vitro cultured periodontal ligament cells (PDLCs).Methods:
The third and fourth mandibular premolars of two mongrel dogs were extracted and the dog PDLCs were in vitro cultured.The autologous roots combined with PDLCs were replanted into the created cavities in the right mandibular edentulous area one month after premolar extraction.Roots replanted without PDLCs on the left mandible served as the controls. The dogs were sacrificed 2 months after the replantation. Paraffin sections were made and stained with hematoxylin & eosin, then examined histologically.Results:
In the samples of root combined with PDLCs implantation, some fiber bundles vertical to the surface of bone were embedded in some inner walls of the alveolar socket opposite to the apical root.Conclusion:
Cultured PDLCs in vitro retain the capacity of PDL-like tissue formation even in the artificial alveolar socket.
