RESUMEN
PURPOSE: To apply research-based learning in education of bachelor intern students of stomatology and evaluate its role in promoting the comprehensive quality of the students. METHODS: Sixty students from grade 2007 and 2008 in school of stomatology, Wenzhou Medical University were enrolled in this study. Thirty of them were randomly selected into a group for research-based learning, while the others were taught with traditional teaching mode. Survey and assessment of the teaching effect was performed after the course. Independent t test was employed to evaluate the differences with SPSS16.0 software package. RESULTS: No significant difference of exam results was revealed between the two groups. Questionnaire survey showed a good evaluation for the teaching mode and the teachers in the group research-based learning, but the evaluation of mastering research capability was lower. CONCLUSIONS: Research-based learning mode promotes the study interest and comprehensive quality of the students. No evidence of interference with mastering clinical skills is disclosed.

Xeroderma pigmentosum is a relatively rare pigment atrophic autosomal recessive genetic disease, mainly due to defect of DNA excision repair capacity, resulting in ineffective removal of UV-induced pyrimidine dimers, and finally cell damage. This paper reported a case of xeroderma pigmentosum with recurrent episodes of oral and maxillofacial carcinogenesis, and discussed the etiology, pathology, clinical characteristics, classification, diagnosis and treatment methods of Xeroderma pigmentosum.

PURPOSE: To investigate the feasibility and indication of condylectomy for treatment of comminuted fractures of the condyle above the neck. METHODS: Sixty-one patients with condylar fractures, treated between September 2007 and September 2011 were reviewed respectively. Among them, 30 underwent open reduction and internal fixation, 15 underwent conservative therapy, and 16 patients (18 sides) who had comminuted fractures of the condyle above the neck underwent condylectomy. All the patients were followed up for 5 to 48 months after treatment to evaluate the outcomes. RESULTS: Among the 16 patients with condylectomy, poor wound healing due to rejection of hemostatic gauze was noted in 1 patient, occlusal deviation occurred in 1 patient, mild mouth opening limitation happened in 1 patient, and anterior open bite was present in 1 patient. The other patients recovered well, without apparent discomfort, malocclusion and facial asymmetry. CONCLUSIONS: For patients with finished maxillofacial growth, condylectomy is a feasible and effective way for management of comminuted fractures of the condyle above the neck. Postoperative occlusal deviation, open bite and limited mouth opening can be corrected with further expectant treatment.
