With laser-based dental treatment coming into increasing use, we introduce in-process monitoring using a two-color pyrometer and spectroscopic measurement ensuring safe treatment. Sound level monitoring is proposed for detecting hard-dental-tissue removal based on the relationship between tissue removal and sound.
