Further, the statistical measurements of curriculum network were adopted to express the most relevant topological features. Subsequently, the minimum spanning tree and parallel coordinates plot were drawn to explore the curriculum community structure, quantify the key courses, and present different courses in time and space relationships. <strong>Results:</strong> The correlation analysis results show that the courses are closely related to each other. The main courses focus on pathology, pathophysiology, oral anatomy and physiology, closely connecting almost all medicine-related courses. The whole course network has an average degree value of 41.53, and a clustering coefficient of 0.78, indicating an obvious small-world characteristic. From the perspective of curriculum attributes, the number of public and theoretical courses was more than that of skills and practical courses. Moreover, the academic performance of skills and practical courses was lower than that of public and theoretical courses. <strong>Conclusion:</strong> The undergraduate dental courses have a progressive structure from basic professional knowledge to professional skills, which is reasonable for the dental education in China. However, some efforts towards curriculum reform based on this study are needed.展开更多

Some of the mainadvantages of these cells are their multifaceted differentiation capacity, along withtheir high proliferation rate, a relative simplicity of extraction and culture thatenables obtaining patient-specific cell lines for their use in autologous celltherapy. PubMed, Scopus and Google Scholar databases were searched forrelevant articles related to the use of DPSCs in regeneration of dentin-pulpcomplex (DPC), periodontal tissues, salivary gland and craniomaxillofacial bonedefects. Few studies were found regarding the use of DPSCs for regeneration ofDPC. Scaffold-based combined with DPSCs isolated from healthy pulps was thestrategy used for DPC regeneration. Studies involved subcutaneous implantationof scaffolds loaded with DPSCs pretreated with odontogenic media, or performedon human tooth root model as a root slice. Most of the studies were related toperiodontal tissue regeneration which mainly utilized DPSCs/secretome. Forperiodontal tissues, DPSCs or their secretome were isolated from healthy orinflamed pulps and they were used either for preclinical or clinical studies.Regarding salivary gland regeneration, the submandibular gland was the onlymodel used for the preclinical studies and DPSCs or their secretome were isolatedonly from healthy pulps and they were used in preclinical studies. Likewise,DPSCs have been studied for craniomaxillofacial bone defects in the form ofmandibular, calvarial and craniofacial bone defects where DPSCs were isolatedonly from healthy pulps for preclinical and clinical studies. From the previousresults, we can conclude that DPSCs is promising candidate for dental and oraltissue regeneration.展开更多
