Chulalongkorn University Theses and Dissertations (Chula ETD)
After tooth loss, a consequent atrophy of the alveolar process always takes place and adversely affect the reconstruction process especially by dental implant. A novel chitosan/dicarboxylic acid scaffold (CS/DA scaffold) has been developed and proven to be an excellent candidate material in bone tissue engineering. This study aimed to evaluate the effects of a CS/DA scaffold with and without seeded primary human periodontal ligament cells (hPDLCs) in mouse calvarial defect model. Eighteen mice were divided into 3 groups of 6 each. Four-millimeter calvarial defects were created on both side of parietal bone and implanted with either CS/DA scaffold or CS/DA …
