Objective: To construct a 3-D model of the masticatory mucosa to measure the thickness of the facial/lingual gingiva and palatal mucosa.
Study Design: Maxillofacial regions of 8 volunteers were scanned using cone-beam computed tomography to generate 3-D maxillary and mandibular models. Digital models were obtained by laser scanning of the impressions.
NEL-like protein 1 (NELL1) is a newly identified secreted protein involved in craniosynostosis and has been found to promote osteogenic differentiation of mesenchymal stem cells. The objective of this study was to investigate the effect of NELL1 on osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) and the potential underlying mechanism. hPDLSCs underwent lentivirus-mediated NELL1 transfection (Lenti-NELL1) and markers of osteogenesis were assessed [alkaline phosphate (ALP), osteocalcin (OCN) and calcium deposition] to evaluate the effect of NELL1 on the differentiation of these cells.

Objective: This study aimed to establish the reference value range of healthy teeth mobility in Chinese youth.
Methods: 200 right side teeth of Han nationality of Chinese youths were measured so as to get the range of the parameters.
Results: All parameters of 14 teeth were achieved.
Objective: To increase the success rate of primary culture of human periodontal ligament fibroblasts (HPLF), and to establish an experimental model for studying HPLF in vitro.
Methods: The primary cells were isolated from human periodontal ligament by explants with enzymatic digestion method. Morphological analysis and immunocytochemical staining were used to characterize the cell lineage, and growth curve assay to evaluate the biological features of HPLF.
