| Research Abstract |
Clinical diagnosis of the early stage of root fracture was difficult. With fluctuation by ultrasonic dental scaler, the root fracture was confirmed with infrared thermography. The cracks were detected in about 10 seconds when the tip was set at less than 60°from the crack, and fluctuation power set from 0.80W to 1.18W. It was found that the Vibro IR method is one of the most effective tools for diagnosis of the root fracture.
