The invention provides a pulp-
vitality fluorescence detection device and a detection method, by employing
fluorescence for detection, the modulated exciting light after passing through a filter is transmitted by a transmitting
fiber, and irradiates the surface of a detected tooth via a probe window and drives the tooth to produce
fluorescent radiation, then the modulated exciting light is received and transmitted by a receiving
fiber in the probe window, and is transferred to a glimmer detection unit via a receiving filter, and then the modulated exciting light enters into a
data processing and
control circuit for being controlled and processed. The invention resolves professional difficult problems which include painless detection of dental diseases and particularly the fast synthetic detection of pulp
vitality, tooth decalcification and carious
dentin, the detection is accurate, and the corresponding data can be directly displayed. By applying the invention, the detection is flexible because one point detection and multi-point detection can be chosen, the detection procedure is capable of rejecting operation mistakes, the detection is rapid, visual and accurate, the detection range is large, and the structure is simple. The invention can be used in places such as stomatological hospitals, dental clinics, etc., in which dental diseases are detected.
