[A case report of combined aesthetic diagnosis and treatment of adult concave deformity].

The non-surgical treatment of adult concave deformity can be achieved by interdisciplinary solution, which includes condylar relocation, fixed orthodontic, and functional occlusion smile design anterior prosthesis. In this study, an adult patient with concave deformity were treated by maxillary occlusal splint, conventional fixed brackets, and upper anterior teeth porcelain veneers to lead mandibular condyle to centric relation, to correct the dental arches for functional occlusion, and to gain the final desired esthetic achievement after treatments.

[A pilot study of establishing course of professional English on stomatology].

The importance of specialized English on stomatology is becoming more and more significant under the new situation. It used to be focused on vocabulary and literature teaching in the original course of specialized English, which was lack of practicability. Thus, we try to establish a course of professional English on stomatology during the postgraduate stage of the seven-year students in our college, in order to complement the course of specialized English on stomatology and improve the students' practical ability to use specialized English. In this paper, the teaching content and method, teaching materials setting and the feedback from students on the course were discussed and analyzed, in order to lay a foundation for better construction of the course.

[Analysis of vertical root fracture with two different techniques of root canal preparation].

PURPOSE: To investigate the relationship of vertical root fracture (VRF) after root canal treatment with two different technique of root canal shaping and provide clinical reference. METHODS: 1702 teeth treated with root canal treatment during recent 2 years. All teeth were divided into two groups according to different techniques of root canal shaping: 643 teeth were prepared with NiTi rotary preparation technique (NRPT) and 1059 teeth were prepared with stainless steel hand K-files preparation technique(SSPT). The clinical symptoms and signs, radiological findings were estimated. The data was analyzed by SPSS 11.5 software package. RESULTS: There were 32 teeth with vertical root fracture, the VRF rate was 1.88%. The VRF rate in NRPT group was significantly higher than in SSPT group (P<0.01). The VRF rate with retreatment history in NRPT group was significantly higher than in SSPT group (P<0.01), but The VRF rate with post and core restoration in both NRPT and SSPT groups was not significantly different(P>0.05). CONCLUSIONS: NiTi rotary preparation technique (NRPT) was closely related with vertical root fracture (VRF). And the VRF risk would be even higher if the tooth underwent root canal retreatment case or a post-core was placed in the root canal.

[Evaluation on clinical value of serum CA-125 level in hepatitis cirrhosis].

OBJECTIVE: To determine the association between elevated levels of serum cancer antigen (CA) 125 and hepatitis cirrhosis in different stage, and also to explore the clinical application value of serum CA-125. METHODS: During June to December in 2008, 200 cases with hepatitis cirrhosis were random selected in our hospital. CA-125 levels were measured by electrochemiluminescence immunization assay in sera collected from these cases which were termed with Child-Paugh classification and analyzed by SAS. RESULTS: Serum CA-125 levels were correlated closely with ascites, primary peritonitis and liver function Child-Paugh classification, but no associated with primary carcinoma of liver and other liver function index,such as ALT, AST, ALB, TBIL and PT. CONCLUSION: The levels of serum CA-125 in hepatitis cirrhosis patients were osculating correlating with lesion of liver and ascite degree, could serve as a sensitive and conventional laboratory index for liver lesion degree and monitoring ascite generation. It was necessary to further study on the association with serum CA-125 level with primary hepatic carcinoma.
