With the laser power and the time of irradiation increased, the sealing depth of dentinal canaliculi increased.

激光功率不变时，牙本质小管的封闭厚度随照射时间的增加而增加；照射时间相同时，牙本质小管的封闭厚度随激光功率的增加而增加，且具有显著性差异。

Results: Laser with different parameters blocked dentinal canaliculi.

结果：不同功率的激光经不同照射时间照射牙本质片后，均可封闭牙本质小管。

In this study, 156 carious teeth from the children aged from 3~11years old were collected and divided into two groups,78 in each group.

收集3~11岁儿童乳牙龋病患者156例，随机分为两组，每组78例，分别采用Carisolv凝胶去腐和常规磨牙去腐，比较两组儿童的感受及治疗效果。

Result:Lactobacillus and streptococcus mutans were found to be the main bacteria in the carious dentin.

结果：牙本质龋中的主要相关菌为乳杆菌和变链菌，龋内层牙本质中的细菌含量较外层少。

METHODS: Immunohistochemical staining was adopted for studying the expression of CaB in healthy and carious teeth, and the results were analyzed by image analysis.

Abstract〕Objective:To study the expression of BMP3 mRNA in human normal,carious and inflammatory pulp tissues.

既往，有学者采用免疫组织化学、核酸分子原位杂交技术，分别研究了BMP〔1〕和BMP-2A基因〔2〕在牙胚中的分布与表达，认为它们在牙胚的发育过程中有重要意义。

AIM:To observe the expression of Smad1,4,5 in h uman dental pulp tissue of normal, carious and inflammatory couditions, and explore the effect of Smad1,4,5 on dental pulp repair after tissue injury.

目的：观察骨形态发生蛋白下游信号转导分子Smad1，4，5在正常、龋坏和炎症人牙髓组织中的表达及表达差异，探讨Smad1， 4，5在牙髓损伤修复过程中的作用。
