Problems solved by technology

However, because tea pigment is easily oxidized into brown, and the color of caries is often brown, therefore, in the actual diagnosis and treatment process, pits and fissures sealed by tea pigment will be mistaken for caries, which will affect the diagnosis and treatment effect.

Embodiment

[0014] 1) Weigh 2g of black tea powder with a balance and pour it into a mortar;

[0015] 2) Add 10 mL of absolute ethanol to the mortar, then add calcium carbonate for grinding, filter, and collect the filtrate;

[0016] 3) Repeatedly add 10 mL of absolute ethanol to the filter residue for grinding and filtration, until the color of the solution becomes obviously lighter, add 10 mL of absolute ethanol again, mix well and let stand for 3-5 hours, filter, and combine the filtrates;

[0017] 4) Distill the obtained filtrate in a distillation device, and when the filtrate is almost evaporated, transfer it to an evaporating dish and evaporate to dryness to obtain tea pigment;

[0018] 5) After dissolving 0.05 g of the obtained tea pigment in 1 mL of absolute ethanol, add 5 mg of magenta, stir to dissolve, then add 4 mL of water, stir until completely miscible, and obtain the dyed tea pigment solution.

[0019] Use the anti-caries device described in the patent (CN 103860283A), or...

Abstract

The invention discloses a dyeing method of tea pigment for pit and fissure sealing. The dyeing method comprises the following steps: performing grinding in absolute ethanol to obtain tea pigment in tea powder, and then, dyeing the tea pigment by adopting magenta. By adopting the obtained dyed tea pigment as a decayed tooth prevention agent to be used for pit and fissure sealing treatment, the sealing effect of the tea pigment can be intuitively judged, and the condition of decayed teeth of a patient after pit and fissure sealing treatment with the tea pigment can be conveniently examined.

Description

technical field [0001] The invention specifically relates to a dyeing method of tea pigment for pit and fissure sealing. Background technique [0002] The surface of human molars is uneven, the main function is to increase the chewing ability of the teeth. There are very thin pits and grooves in the recesses, the diameter is only 0.5 mm, but the depth can reach 1.5 mm. Food residues and bacteria are easy to accumulate in the pits and grooves, and it is not easy to Removed, under the action of time, dental caries occurs. In the previous patent (CN 103860283A), it has been disclosed that tea pigment can be deposited in pits and fissures to seal the pits and fissures to prevent dental caries. However, because tea pigment is easily oxidized into brown, and the color of caries is often brown, therefore, in the actual diagnosis and treatment process, pits and fissures sealed by tea pigment will be mistaken for caries, which will affect the diagnosis and treatment effect.
