Example Embodiment

[0029] Example 1

[0030] In this embodiment, a toothpaste containing coloring Chinese medicine components is used as a test product to evaluate the risk of tooth coloring that contains coloring Chinese medicine components.

[0031] A risk assessment method for tooth staining, including the following steps:

[0032] Step 1: Choose a human tooth brushing model to test. Such as figure 1 , figure 2 As shown, the human tooth brushing model includes a bottom plate 4, a pressure sensor 2 and a detachable fixing plate 3 mounted on the bottom plate 4. The fixing plate 3 is provided with a through rectangular hole, and the rectangular hole is used to fix the experimental tooth sample. The bottom plate 4 is welded with a threaded rod 10 perpendicular to the bottom plate 4, and a fixing nut 9 is screwed on the threaded rod 10, and the fixing nut 9 can move up and down along the threaded rod 10 when the fixing nut 9 is rotated. The fixing nut 9 is rotatably connected with a mounting part, and...

[0043] Example 2

[0044] In this embodiment, black tea is used as the test product to evaluate the risk of black tea staining the teeth.

[0045] A method for evaluating the risk of tooth staining, including the following steps:

[0046] Step 1: Choose a human diet model for experimentation. Such as image 3 As shown, the human diet model includes a bracket 11, a fixing unit, and a driving part for driving the fixing unit to rotate. The fixing unit is rotatably connected to the bracket 11, and the fixing unit is used to fix the experimental tooth sample. A horizontally arranged sliding groove is opened on the side of the support 11, and a coloring box 16 located below the fixing unit is slidably connected to the sliding groove, and the upper opening of the coloring box 16 is opened. When the fixing unit of the coloring box 16 rotates, the experimental tooth sample can be located in the coloring box 16; the bracket 11 is provided with a baking lamp 14 above the fixed unit, and the ...

Abstract

The invention relates to a risk assessment method of teeth coloring, in particular to a risk assessment method of food, medicines, oral care supplies and the like for human dental coloring. The risk assessment method of teeth coloring comprises the following steps that step 1, laboratory models of mouth entrance products people used such as the food, the medicines and the oral care supplies are established; step 2, a baseline test of experimental teeth samples is carried out, and L values of all the untreated experimental teeth samples are measured by a colorimeter; step 3, the experimental teeth samples are placed in the models for many times treatments, during the space between each treatment, and the experimental teeth samples are placed in artificial saliva and put into a 37 DEG C constant temperature and humidity box; and step 4, the L values of all the experimental teeth samples treated by the step 3 are measured by the colorimeter, data analysis is carried out on the L values ofthe experimental teeth samples treated before and after, and the risk assessment is carried out on teeth coloring. According to the application scheme, the teeth dyeing risk of the mouth entrance products such as the food, the medicines and the oral care products can be can be effectively assessed.

Description

technical field [0001] The invention relates to a method for evaluating the risk assessment of tooth staining, in particular to a method for assessing the risk assessment of human tooth staining by food, medicine and oral care products. Background technique [0002] There are many reasons for tooth staining, which can be roughly divided into two types: endogenous and exogenous. Exogenous coloring mainly comes from smoking, drinking tea, drinking coffee and eating colored foods. The colored substances are adsorbed on the organic film on the surface of the teeth. If the stained film cannot be removed in time and effectively, it will gradually deposit on the On the surface of tooth enamel, stains that are difficult to remove form, and then gradually develop into more difficult-to-remove calculus or plaque, resulting in yellowing of teeth; endogenous coloring refers to the color of teeth caused by internal or drug factors Variety. [0003] The whiteness of teeth is the most ba...
