[The expression of interleukin-10 mRNA in gingival lesion of different clinical states in patients with adult periodontitis].

Objective: To investigate the expression of interleukin-10 (IL-10) mRNA in gingival tissue of active and stable stage in patients with adult periodontitis.

Methods: 12 patients with acute abscesses of the periodontium, 12 patients after periodontal initial treatment and 6 periodontal healthy patients having extraction of impacted wisdom tooth were randomly divided into group A (active stage group), group B (stable stage group) and the control group. Biopsies of gingival tissues were collected from every subject of three groups.

[Effect of periodontal initial therapy together with Chinese herbal compound for clearing heat and detoxification on interleukin-1 beta and tumor necrosis factor-alpha in gingival crevicular fluid of patients with chronic periodontitis].

Objective: To observe the effect of periodontal initial therapy together with Chinese herbal compound for clearing heat and detoxification (Abbr. TCM) on the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in gingival crevicular fluid (GCF) of patients with chronic periodontitis (CPD).

Methods: Thirty-four teeth of 24 patients with CPD were randomly assigned to the control group (17 teeth of 11 patients) and the treated group (17 teeth of 13 patients), they were treated for 8 weeks with periodontal initial therapy, but TCM was given additionally to the treated group.

[Study on the expression of IL-10 mRNA and the protein in gingival tissues of patients with chronic periodontitis].

Purpose: To investigate the cell type which express IL-10 mRNA and the protein in gingival tissues of patients with chronic periodontitis.

Methods: 12 patients with chronic periodontitis who were undergoing flap operation were randomly chosen as periodontitis group;10 patients undergoing gingivectomy were chosen as gingivitis group;6 patients undergoing extraction of impacted teeth were chosen as control group. Assays of in situ hybridization and immunohistochemistry were used to observe the expression of IL-10 mRNA and the protein in gingival tissues of each group respectively .

[Observation of the clinical effects of two kinds of resin materials for restoring the defects of maxillary incisor].

To analyse and compare the effects of the resin materials of etched and nonetched groups in restoring the defect of maxillary incisor. 120 teeth were divided into two groups and filled by two kinds of materials. One year follow up results was studied.
