Abstract: Caries is a common disease against human health. Timely detection of early caries can maximize the preservation of teeth. Photothermal radiometry (PTR) has been a novel infrared testing technology for caries detection in recent years.In this paper, progress of this method in the field will be reviewed, and the principle of this method,imaging technology and The Canary System based on this method will also be particularly introduced.

Key words: caries , detection, photothermal radiometry
