Abstract

Liquid-assisted hard tissue ablation has been paid more and more attentions in recent years and its enhancement mechanism has not yet been fully understood. In the present paper, the dynamic process of cavitation bubble and microjet generation induced by Ho:YAG laser, as well as their effects on hard dental tissue ablation were monitored by a high-speed camera. The results showed that the maximum size of the cavitation bubble increases with the increase of laser energy, and the collapse time of cavitation bubbles is also extended accordingly.
