Embodiment 1

[0013] Take 5.2g of resorcinol, 1.8g of potassium hydroxide and 5.2ml of water, and mix to obtain II liquid. 40% by weight formaldehyde aqueous solution was used as liquid I, and the volume ratio of the liquid I and the liquid II was mixed with the liquid II at a volume ratio of 2:1 to obtain the phenolic resin desensitizing agent 1. Immediately after mixing, it was used in the experimental example.

Embodiment 2

[0015] The phenolic resin desensitizing agent 2 was prepared in the same manner as in Example 1, except that 1.3 g of potassium fluoride was added to the II solution.

Embodiment 3

[0017] The phenolic resin desensitizer 3 was prepared in the same manner as in Example 1, except that 1.3 g of potassium fluoride and 0.5 g of calcium hydrogen phosphate were added to the II solution.

Abstract

The invention provides a fluorine / potassium-containing phenolic resin desensitizer which is the reaction product of the following substances: solution I: 40 wt% formalin; and solution II: 5.2g of resorcinol, 1.8g of potassium hydroxide and 5.2ml of water. The volume ratio of the solution I to the solution II is 2:1. The fluorine / potassium-containing phenolic resin desensitizer provided by the invention has excellent short-term and long-term effects for treating dentin hypersensitivity, and can be recommended for clinical application.

Description

technical field [0001] The invention relates to the field of oral cavity, in particular to a potassium fluorine-containing phenolic resin desensitizer. Background technique [0002] Dentin hypersensitivity (DH) refers to the short and sharp pain caused by external stimuli on exposed dentin, and cannot be attributed to tooth defects or lesions caused by other specific reasons. Typical stimuli include temperature, blowing, etc. Aerosol, mechanical or chemical stimuli. The "Epidemiological Survey on Dentin Sensitivity in Chinese Adults" released in 2008 showed that 29.7% of adults aged 20-60 in my country were troubled by dentin sensitivity, and the high-incidence age group was 50-59 years old, with a prevalence rate of 39.1%. According to foreign reports, the incidence rate of dentin hypersensitivity in the adult population is 4% to 74%, and the incidence rate in women is higher than that in men. There are many clinical methods for the treatment of dentin hypersensitivity, su...
