1. AIM:To investigate the expression of matrix metalloproteinase-2(MMP-2) in the pulp of the healthy and carious tooth and to evaluate the relationship between the expression of MMP-2 and caries developement.
目的：观察基质金属蛋白酶MMP-2在健康及不同程度龋损牙齿牙髓中的表达，初步研究MMP-2与龋病发展的关系。
2. METHODS: The expression of MMP-2 in of the pulp of the healthy and carious tooth were examined by immunohistochemical staining, RT-PCR, real-time PCR and western-blot.
以健康、浅龋和深龋牙齿中牙髓组织为研究对象，利用免疫组化、RT-PCR、实时荧光定量PCR和Western印迹检测MMP-2在其中的表达差异。

3. The approach involves the use of hand instruments only to remove carious tooth substances and restoring the cavities and sealing any adjacent enamel fissures with glass-ionomer cement.
在儿童牙科治疗中，高速磨牙机的使用常造成儿童恐惧看牙的因素，此时运用ARF的方法，在儿童牙科处理上常有正面的效果。
4. Significantly higher levels of NOS were found in pulp of carious tooth and traumatic pulp, but lower in inflammatory pulp.
这种染色在龋病、外伤时有不同程度的增强，而在炎症时则减弱。
5. Distribution of early carious lesions on permanent tooth surfaces and its relationship with dental plaques
