Abstract
The invention discloses a dyeing method of tea pigment for pit and ditch sealing, which is to obtain the tea pigment in tea powder by grinding in absolute ethyl alcohol and then dye the tea pigment by adopting fuchsin. The dyed tea pigment is used as an anticariogenic agent for pit and furrow sealing treatment, can be used for visually judging the sealing effect of the tea pigment, and can be greatly convenient for diagnosing the dental caries of patients after the pit and furrow sealing treatment of the tea pigment.
Description
Technical Field
The invention particularly relates to a dyeing method of tea pigment for pit and ditch sealing.
Background
Human molar has uneven surface, mainly functions of increasing the chewing capacity of teeth, has very thin pits with the diameter of only 0.5 mm and the depth of 1.5 mm in the concave position, easily accumulates food residues and bacteria in the pits, is not easy to remove, and decayed teeth occur under the action of time. It has been disclosed in the prior patent (CN 103860283A) that tea pigment can be deposited in the sulcus to achieve the effect of plugging the sulcus to prevent the occurrence of dental caries. However, because the tea pigment is easily oxidized into brown and the color of the decayed tooth is often brown, the pit and fissure sealed by the tea pigment can be mistaken for the decayed tooth in the actual diagnosis and treatment process, thereby affecting the diagnosis and treatment effect.
Disclosure of Invention
In order to overcome the problems, the invention provides a dyeing method of tea pigment for pit and furrow closure, which has the advantages of quick coloring, bright color and difficult falling, can be used for visually judging the closure effect of the tea pigment and can greatly facilitate the examination of the dental caries condition of a patient after the pit and furrow closure treatment of the tea pigment.
In order to achieve the purpose, the invention adopts the following technical scheme:
A dyeing method of tea pigment for pit and furrow closing comprises the following steps:
1) adding absolute ethyl alcohol into tea powder according to the mass volume ratio of 1: 2-5 g/m L, adding sodium carbonate for grinding, then filtering, and collecting filtrate;
2) Repeatedly adding equal amount of anhydrous ethanol into the residue, grinding, filtering, adding equal amount of anhydrous ethanol again after the solution color is obviously reduced, mixing, standing for 3-5 hr, filtering, and mixing filtrates;
3) and (3) evaporating the obtained filtrate to dryness until the solvent is completely volatilized, adding absolute ethyl alcohol into the obtained tea pigment according to the mass volume ratio of 1: 10-20 g/m L to dissolve, adding fuchsin with the weight of 10% of that of the tea pigment, stirring to dissolve the fuchsin, and then adding water to adjust the concentration of the ethyl alcohol to be lower than 20 vol% to obtain the dyed tea pigment solution.
The invention adopts fuchsin as a coloring agent, not only because the fuchsin is safe, fast in coloring and bright in color, but also because the fuchsin can generate mauve ion association particles through electrostatic interaction with tea pigment with anions, the fuchsin is not easy to fall off.
The tea pigment after red dyeing of the product of the invention is used as an anticariogenic agent, which not only can intuitively judge the sealing effect of the tea pigment, but also is convenient for diagnosing the dental caries condition of a patient after pit and furrow sealing treatment. Through detection, the dyeing effect can last for 1-2 years by dyeing according to the method disclosed by the invention, and the whole treatment period of pit and furrow closing can be effectively covered.

Detailed Description
In order to make the present invention more comprehensible, the technical solutions of the present invention are further described below with reference to specific embodiments, but the present invention is not limited thereto.
Examples
1) Weighing 2g of black tea powder by using a balance, and pouring the black tea powder into a mortar;
2) adding 10 m L anhydrous ethanol into a mortar, then adding calcium carbonate for grinding, filtering, and collecting filtrate;
3) repeatedly adding 10m L anhydrous ethanol into the residue, grinding, filtering, adding 10m L anhydrous ethanol again after the solution color is obviously reduced, mixing, standing for 3-5 hr, filtering, and mixing filtrates;
4) Distilling the obtained filtrate in a distillation device, transferring the filtrate into an evaporation dish when the filtrate is quickly evaporated, and evaporating to dryness to obtain tea pigment;
5) dissolving 0.05g of the obtained tea pigment in 1m L anhydrous ethanol, adding 5mg of fuchsin, stirring to dissolve, adding 4m L water, and stirring to completely dissolve, thus obtaining the dyed tea pigment solution.
The caries preventing device disclosed in the patent (CN 103860283A) is adopted, or a bonding rod is used for dipping a small amount of dyed tea pigment solution to be uniformly coated on the pit and furrow of the tooth, wiping is carried out after stopping for several seconds for microscopic observation, the pit and furrow can be seen to be sealed by the mauve tea pigment, and the sealing performance is good and no defect can be seen under the observation of an electron microscope. In addition, long-term tracking tests show that the dyeing effect can last for 1-2 years and can effectively cover the whole treatment period of pit and furrow closure.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
