Background

In a common way of observing dental plaque, a reagent is applied to the tooth surface, and then the condition of the dental plaque on the tooth is determined according to the color developed on the tooth surface. This method takes a relatively long time to complete a plaque observation, and after the completion of the observation, it requires a coating of an agent that cleans the tooth surface, and the coating of the agent may remain on the tooth surface for several days, which may affect the appearance.

Some dental plaque observers also appear in the market, but only can observe rough conditions of 2 to 3 local teeth at a time, and the observers need to stretch into the oral cavity, so that oral infection is easily caused, and the observation of the oral teeth needs to be assisted by a mirror or a second person, so that the operation is complicated, and the real conditions of dental plaque are not easily observed. Some dental plaque observers are easy to cause stabbing injury and short-time dim eyesight to eyes of users by lamplight when in use.

The area array detector 9 is a digital receiver such as a CCD or a CMOS, or an enhanced CCD or CMOS receiver for weak signal detection. And a beam splitter 6 is arranged between the tooth sample 1 to be detected and the area array detector 9 so as to realize transmission of incident ultraviolet excitation light and reflection of excited visible light wave bands. A high-pass filter 8 is arranged in front of the area array detector to extract the dental plaque characteristic fluorescence between 600nm and 800 nm.
