| Outline of Final Research Achievements |
the potential of the Er:YAG laser to cut hard dental tissues without significant thermal or structural damage would eliminate the need of an ultrasonic unit. However, it is difficult to use a straight tip that has widely applied for cavity preparation because the access is limited. Recently, some types of tips have been developed, the purpose of this study was to investigate the performance of Er:YAG laser with a narrow tip (diameter=0.4mm) to prepare hard tissues.
All specimens were also photographed using micro computed tomography. Then microscope images were recorded and analyzed in the same way as contact microradiographs. Some samples were observed by optical computed tomographyelectron microscopy.
