| Outline of Final Research Achievements |
The choice of the probe is important about the trial manufacture of the carious identification device. It is demanded visible light penetrating the probe of the carious identification device and that we can insert it in oral cavity. We used a tip (P400T, J.Morita) for radiation of the Er:YAG laser for dental treatment as a probe this time.
It was incident on a probe by light output by He-Ne laser and measured strength of appearance shone light by a power meter (PM20, so laboratory) from the tip. After measured optical power when we applied black paint to the probe tip, we made the probe tip touch simulated preparation, and the paint of the probe tip made it exfoliate partly. As a result of measured strength of the light again, optical power significantly improved as compared with before contact with the preparation. We measured hardness of the preparation by measuring optical power, and this results suggested that they could distinguish carious.
