Abstract
Dentinal hypersensitivity results when stimulation causes the fluid in open dentinal tubules to undergo pressure changes, which activates mechanoreceptor nerves and results in pain. Treatment with fluoride varnish forms a protective layer of calcium fluoride that prevents this fluid flow, thereby reducing dentinal sensitivity.
摘要
当刺激导致开放牙本质小管中的液体发生压力变化时，就会引发牙本质过敏，这种压力变化会激活机械感受器神经并导致疼痛。使用含氟涂料进行治疗可形成一层氟化钙保护层，防止这种液体流动，从而降低牙本质敏感性。
