MEASURING DEVICE AND METHOD FOR DETERMINING THE ACTIVITY STATUS OF INITIAL DECAYED ENAMEL LESIONS

摘要

The invention relates to the determination of the activity status of initial decayed enamel lesions using a single measuring process. To this end, an optical distance measuring system comprising a measuring head which is housed in a handpiece is used to create a depth profile from a porous structure in the enamel by means of an optical measurement, and said depth profile is associated with a classification of depth profiles, different classifications corresponding to different states of activity. For the optical measurements, either distance measurements are provided, that can be supported by intensity measurements of reflected light of at least one wavelength which is sharply focussed onto the surface, or the intensity measurements are carried out exclusively.
