The technique of laser-induced cavitation using an Er:YAG laser system is increasingly being adopted in dental medicine for the removal of harmful biofilm on teeth and gums. The amount of induced cavitation depends on the shape of the fiber tip, through which high-intensity laser radiation is introduced into the fluid. In this study, the cavitation process was recorded with a high-speed camera and analyzed using MATLAB. Three different fiber tip shapes were examined. Video processing techniques revealed that the conical tip is the most effective in generating cavitation.
