Abstract
The laser light was first introduced as a laser surgical knife in the medical application, which used the thermal energy of laser light. After that, various kinds of laser lights of different wavelengths have been developed and applied in the medical field. Today, the interaction between laser lights and optical characteristics of tissue by laser lights is considered more, and a laser light which gives the best effect to a tissue is selected for each treatment. In this report, I would like to introduce the application of Erbium:YAG laser for dental treatments and the point of view for development of Erbium:YAG laser. Then, I would like to report for the point of view of the perspective in the near future.
