[0002] Dental plaque is currently a hot topic in oral microbiology and ecology research. Researchers have established a variety of models to study the mechanism and process of plaque formation. In the field of dentistry, the current common dental plaque model is to transfer bacteria into a test tube culture medium, form a biofilm on the inner wall of the test tube to simulate the formation of dental plaque, and then quantify the dental plaque by detecting the absorbance of the liquid in the test tube.

[0003] Currently, the test tube dental plaque model cannot be visualized, and the model cannot simulate real brushing activities, resulting in less rigorous test results. Summary of the invention

[0004] In view of the shortcomings of the existing technology, a method for simulating and testing the effect of brushing teeth to remove dental plaque is proposed based on VISIA technology, which can visualize and digitize the effect of dental plaque removal.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for simulating and testing the effect of brushing teeth to remove dental plaque based on VISIA technology, comprising the following steps:

[0006] S1, removing the artificial teeth from the standard tooth model and immersing them in the PVP solution so that the PVP solution is evenly attached to the artificial teeth;

[0007] S2, placing the artificial teeth in an oven for drying;

[0015] S10, remove the test artificial teeth, and slowly rinse off the residual toothpaste in the control toothpaste group and the sample toothpaste group with clean water;

[0016] S11, fix the buccal side of the artificial tooth after brushing and grinding on the shooting position of the image analyzer (VISIA) through an accessory, take an image and save the image;

[0017] S12, select appropriate light source pictures and use Image Pro Plus software to analyze the photos.

[0018] As a preferred solution of the present invention, the concentration of the PVP solution in step S1 is 20%.

[0019] As a preferred solution of the present invention, in step S2, the drying temperature is 60° C. and the drying time is 8 to 12 hours.

[0020] As a preferred solution of the present invention, in step S4, the drying temperature is 60° C. and the drying time is 8 to 12 hours.

[0021] As a preferred solution of the present invention, in step S6, the drying temperature is 60° C. and the drying time is 8 to 12 hours.

[0022] As a preferred solution of the present invention, the number of brushing times in step S9 is to brush the front and back of the artificial teeth up and down 60 times respectively.

[0023] As a preferred solution of the present invention, the analysis method in step S12 is: divide the teeth into three parts: two sides and the middle, the two sides are the tooth gap area, and the middle is the tooth surface area. By calculating the area of ​​the red area of ​​the artificial tooth / the area of ​​the tooth, the plaque removal rate of the tooth gap area and the tooth surface area can be calculated.
