Effect of Chinese nutgall solution on micro-hardness of root canal dentin / 实用口腔医学杂志

ABSTRACT

Irrigation is one of the most important steps of root canal preparation. This study evaluated the dentin micro-hardness changes irrigated by Chinese nutgall solution and other irrigants, and investigated the influence of each irrigant on root canal dentin hardness. The results showed that all kinds of solution decreased the micro-hardness of root canal dentine. Chinese nutgall solution group did not significantly decrease the dentine micro-hardness with concentration increased over time.
