Current general odontotherapy uses a diamond small tool to remove caries. Mechanical grinding has generated a vibration, heat, noise, and so on, and causes patients mental and physical pain. In order to avoid these problems, he proposed micro water jet machining. The advantages of using water jet are that it can remove only soft carious dentin and causes less heat during processing than does mechanical grinding. He measured Vickers hardness in caries and showed that caries is soft compared with normal dentin. In this study, he compared performance of water jet and abrasive water jet machining with mechanical grinding for machining force and heat. In addition, he used a harmless abrasive (nut powder) to remove carious dentin. It is found that abrasive water jet machining is useful for odontotherapy.
