With the development of traditional Chinese medicine, common bletilla rubber is widely used in the treatment of bacterial infection, tumor, digestive tract ulcer, gastric mucosal lesions, external blood and so on. In this article, the pharmacological properties and chemical components of common bletilla rubber were summarized, and the mechanisms and pathways of each ingredient of common bletilla rubber were also analyzed. The application of common bletilla rubber in the field of oral diseases, including oral mucosal diseases, caries, intramedullary barrier materials and periodontal tissue engineering scaffold materials were summarized. It was proved that common bletilla rubber could play an important role in the fields above, no matter which form it was in. This article may provide reference for the further promotion of common bletilla rubber in the treatment of oral diseases.

Objective To discuss the effect of the combination of traditional Chinese and western medicine on the cellular immune functions and clinical manifestations of patients with recurrent oral ulcer (RAU). Methods 32 patients with RAU were randomly selected and treated with the combination of traditional Chinese and western medicine. The changes of their peripheral blood T lymphocyte subgroups ,before and after the treatment, were measured using immuo enzymatic technique. The healing period and recurrence frequency were recorded. Results The ratios of the patients CD 3, CD 4 and CD 4/CD 8 ,after the treatment ,went up obviously and had significant difference with those before the treatment ( t=4.53-11.31,P 0.01).The healing period shortened dramatically and the recurrence frequency lowered obviously. Both had distinctive difference compared with those before the treatment ( t=8.68,13.63, P 0.01). Conclusion The therapy of combination of traditional Chinese and western medicine can greatly improve RAU patients cellular immune function, promote the healing of ulcer and reduce ulcer recurrence. It deserves a broadly clinical application.

目的:研究局部应用碱性成纤维生长因子(basic fibroblast growth factor,bFGF)治疗复发性口腔溃疡(RAU)的近期疗效.方法:80例RAU患者随机分两组,试验组溃疡面局部应用bFGF,对照组多贝尔氏液含漱,记录溃疡面愈合时间和疼痛缓解情况,进行统计学分析.结果: bFGF有促进溃疡面愈合,缓解疼痛的作用.结论:bFGF对RAU溃疡面的愈合有应用价值.

口腔门诊的交叉污染与医护人员有密切关系.长期以来,由于经济条件的限制和人们口腔卫生保健意识较淡薄,我国口腔医学事业发展较为落后,使得临床医师在从业过程中,形成了一些传统的观念和不良的操作习惯.现在,随着我国经济高速发展和社会的进步,口腔医学也得到了迅速发展,许多先进的诊疗技术同国际接轨,人们的卫生观念和就诊要求趋向完美化,也给口腔执业人员提出了高标准的要求.本文通过分析口腔医师对病人的诊疗过程,探讨在减少口腔门诊交叉污染方面值得注意的几个问题.
