متن کاملAdhesion of human periodontal ligament cells by three-dimensional culture to the sterilized root surface of extracted human teeth.
Residual periodontal ligament (PDL) and cement mass on the roots of extracted teeth are factors that considerably affect tooth transplantation. Therefore, when normal extracted teeth are used for autologous transplantation, it is necessary to regenerate the PDL of the root surface. Here we describe a method to examine human PDL cell adhesion on sterilized root surfaces. Sample teeth were extrac...

متن کاملCalculation of natural frequencies of teeth supported with the periodontal ligament.
Natural frequencies and vibration modes of four kinds of teeth were calculated by using a mechanical model. The alveolar bone and the tooth were assumed as rigid bodies, while the periodontal ligament was assumed as an elastic spring. All the natural frequencies were within a range of 1 to 10 kHz. The first natural frequencies of four teeth were about 1.5 kHz, and decreased as the root length d...
متن کاملIndication for Intentional Replantation of Teeth
Intentional replantation can be used for root canal re-treatment when other methods are deemed unsuitable. This procedure is based on the approach used to obtain good clinical outcomes for replantation of an avulsed tooth. The key to a successful procedure is atraumatic extraction and replacement in the socket without damage to the periodontal ligament. This case series presents the long-term o...
