A risk assessment method for tooth staining

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...

Problems solved by technology

[0004] At present, although there are relevant literature reports on the research on tooth staining of imported products such as food, medicine and oral care products, they are all researched from the aspects of coloring principle and restoration, and there is no systematic and complete risk assessment method for tooth staining. For those who are concerned, tooth staining seriously affects human aesthetics, and for product R&D companies, it also increases the risk of consumer complaints after the product is launched. Therefore, there is an urgent need for a systematic and simple tooth staining risk assessment device and test method to evaluate the impact of each product on teeth. risk of coloring
