| Outline of Final Research Achievements |
It is difficult to make a definite diagnosis of root canal crack at the clinic.It is important to detect the micro-cracks. Our purpose of this study is to detect the micro-cracks with infrared thermography.
The micro-cracks on the root canals were created with tapered indenter under an optical microscope.The micro-crack surfaces were vibrated using ultrasonic scaler to generate frictional heat.The infrared-ray thermography recorded the frictional heat at the micro-cracks.We examined with using specular reflector.
The width of micro-cracks could be detected in the range of 4.1～50μm.With using specular reflector,the micro-cracks could be detected on the image of specular reflector.
