摘要：
A dental apparatus (4) is provided. The dental apparatus includes a handle (6). A controller (20) operably couples to the housing and includes a calibration module (44) configured to calibrate the dental apparatus. The dental apparatus emits a modulated excitation signal and the calibration module compares a detected modulated fluorescence signal with first and second reference values such that if a difference between the detected modulated fluorescence signal and the second reference signal is greater than a difference between the first reference value and the second reference value then the first reference value is updated.
