Embodiment Construction

[0029] A method for measuring and calibrating a tooth whitening cold light instrument, comprising the steps of:

[0030] (1) Set the environmental conditions for measurement and detection;

[0031] (2) Technical requirements for installing radiometers;

[0032] (3) Carry out the working wavelength range test, the radiation test within the range of 400nm~650nm, the radiation uniformity test, the radiation stability test, the radiation test above 650nm and the ultraviolet radiation illuminance test.

[0033] In step (1), the environmental conditions for setting measurement and detection are specifically: air temperature: 15°C-35°C; relative humidity: relative humidity is not greater than 85%; power supply voltage and frequency: (220±11)V, (50±1 ) Hz.

[0034] In step (2), the specific technical requirements for setting up the radiometer are: there should be consistent spectral sensitivity within the wavelength range of 200nm to 1100nm, and the diameter of the measuring hole of...

Abstract

The invention discloses a measurement and calibration method of a tooth whitening cold light instrument. The measurement and calibration method comprises the following steps of (1) setting environmental conditions for measurement and detection, (2) setting technical requirements of the radiometer, and (3) respectively carrying out a working wavelength range test, a radiation test in a range of 400-650 nm, a radiation uniformity test, a radiation stability test, a radiation test above 650 nm and an ultraviolet radiation illumination test. The measurement characteristics of the tooth whitening cold light instrument and a corresponding measurement and calibration method are given, and measurement indexes of the measurement characteristics are put forward.

Description

technical field [0001] The invention relates to the technical field of medical measurement and calibration, in particular to a measurement and calibration method for a tooth whitening cold light instrument. Background technique [0002] Cold light tooth whitening technology is a new tooth whitening technology. This technology uses optical fiber to transmit high-intensity blue light with a wavelength in the range of 480nm to 520nm. It is filtered by two optical lenses that have been coated for more than 30 times to remove harmful ultraviolet rays. and infrared rays, thus irradiating to H 2 o 2 and silicon dioxide with a diameter of about 20nm as the main whitening agent, so that the whitening agent can pass through the enamel and dentin tubules in the shortest time to produce redox effect on the pigment deposited on the surface and deep layer of the tooth, so as to achieve the effect of whitening . This whitening technology not only has a whitening effect on teeth stained ...
