Outline of Final Research Achievements

The aim of this research is to elucidate the kinetics of cavitation agitated by LAI(Laser-Activated Irrigation) and establish the clinical application of the new tips of LAI.
We investigated the root canal irrigation pressure generated outside the apical foramen. It showed that LAI is relatively safer than a conventional irrigation using only syringe and the irrigation activated by Er:YAG laser will be recommended in the future.
Furthermore, we found that the irrigation activated by Er:YAG laser is more effective than a conventional irrigation in the efficacy of irrigation through lateral canals.
