Objective To observe the clinical effects of GLUMA desensitizer in treatment of dentin hypersensitivity.

观察GLUMA系统处理剂治疗本质过敏症临床疗。

The additional enamel (much harder than the dentin in tooth interiors) makes hypsodont teeth more wear-resistant than low-crowned teeth are.

额外珐琅质（比其内部质硬很多）使高冠齿比低冠齿耐磨得多。

Conclusions:Light cure pit and fissure sealant technique can be used to treat pit and fissure caries after the cariated dentin has been cleared up.

在彻底清除龋坏体组织后用光固化窝沟封闭术可以做为磨 合面窝沟龋预防治疗方法之一。

Dentin matrix protein 1 (DMP1) is expressed in both pulp and odontoblast cells and deletion of the Dmp1 gene leads to defects in odontogenesis and mineralization.

本质基质蛋白-1（DMP1）在髓和成本质细胞中均有表达，Dmp1基因缺失可导致齿发育和矿化障碍。
