Description

Technical Field

[0001] This invention relates to the field of dental oral hygiene consumables technology, specifically a dental sandblasting powder for improving flavor and its preparation method. Background Technology

[0002] Sandblasting technology uses compressed gas (usually air) to propel abrasive powder onto the tooth surface, where it mixes with a liquid medium (usually water) to clean the tooth surface. Specifically, it can remove plaque, soft deposits, tobacco stains, tea stains, etc., effectively preventing periodontal disease and maintaining dental health.

[0003] The main factors affecting the effectiveness of blasting powder include the hardness of the powder material, the particle size of the powder, and the taste. The hardness of the powder material determines whether it can be used for teeth cleaning; if the material is too soft, the cleaning effect will be poor, while if it is too hard, it will damage the tooth surface.

[0004] Sodium bicarbonate is a classic dental polishing powder, known for its high cleaning efficiency, but its salty taste leads to poor patient comfort. Commercially available products mask the saltiness of sodium bicarbonate by adding sugar or saccharin / saccharin salt to improve taste. However, sugar is unsuitable for diabetic patients and can cause tooth decay; saccharin / saccharin salt, at normal doses, cannot mask the saltiness of sodium bicarbonate, and excessive doses can result in a bitter taste.

[0005] Glycine blasting powder has low hardness and a slightly sweet taste, making it more comfortable for patients to use. However, it has low cleaning efficiency and cannot remove plaque and stains.

[0006] Erythritol blasting powder combines the advantages of both and has superior performance, but it is not sweet enough and requires the addition of chlorhexidine as an additive when used subgingivally. It also tastes bitter, and a single type of erythritol blasting powder cannot meet the diverse needs of doctors. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dental blasting powder with improved flavor and its preparation method.

[0008] The technical solution to achieve the objective of this invention is: A dental blasting powder for improving flavor, comprising mogroside, wherein the mogroside comprises 0.01–20% by mass of the blasting powder, preferably 0.01–5%.

[0009] The purity of the mogrosides is above 30%.

[0010] The blasting powder also includes at least one of an adhesive, a pH adjuster, an anti-caking agent, and a sweetener.

[0011] The adhesive content in the blasting powder is 0.5–10%, and hydroxypropyl methylcellulose (HPMC) can be used specifically.

[0012] The pH adjuster is present in 0.1–3% of the sandblasting powder, and disodium hydrogen phosphate can be used specifically.

[0013] The anti-caking agent is present in 0.1–2% of the sandblasting powder, and may specifically be silicon dioxide.

[0014] The sweetener content in the blasting powder is 0.01%-5%.

[0015] The sweetener is at least one of steviol glycoside, glycyrrhizin, stevia glycoside, neohesperidin, xylitol, erythritol, sorbitol, maltitol, honey / maple syrup, and ripe banana puree / plum puree.

[0016] A method for preparing dental air polishing powder with improved flavor includes the following steps: 1) Dissolve mogrosides in an ethanol solution, and then spray the mixture onto the surface of the base blasting powder; or directly mix mogroside powder with the base blasting powder. 2) Mix the adhesive, pH adjuster, anti-caking agent and sweetener with the powder obtained in step 1) until homogeneous; 3) Dry the well-mixed powder until the moisture content is <0.5%.

[0017] The base blasting powder is sodium bicarbonate or glycine powder.

[0018] This invention provides a dental blasting powder with improved flavor and its preparation method. This blasting powder introduces mogrosides into the dental blasting powder system for the first time, solving the bitterness problem of traditional products. The spray coating process achieves uniform loading of mogrosides on the surface of the abrasive, avoiding high-temperature deactivation. It also enhances particle adhesion and prolongs the sweetness release time by synergistically using hydroxypropyl methylcellulose (HPMC). By utilizing the natural antibacterial properties of mogrosides, the blasting powder is endowed with the dual functions of "cleaning-antibacterial". Detailed Implementation
