Medical tooth polishing paste is one of the commonly used materials in dental clinics. It is mainly used to remove stains on the tooth surface and polish teeth to achieve the purpose of improving oral beauty and protecting tooth enamel. Imported medical tooth polishing paste has received widespread attention due to its advanced formula and stable performance. This article will systematically analyze the main components of imported medical tooth polishing paste, reveal its composition characteristics and mechanism of action, and provide a reference for clinical application and product development.
1. Basic composition and functional classification of polishing paste
Medical tooth polishing paste mainly includes abrasives, binders, lubricants, thickeners, active ingredients and auxiliary ingredients . The ratio of different ingredients determines the polishing effect and safety of the polishing paste. Abrasives are the core components of polishing paste and are responsible for mechanically removing stains and stains on the tooth surface. Binders make the abrasives evenly distributed and ensure the stability of the paste. Lubricants and thickeners work together to enable the abrasives to slide smoothly during the polishing process to prevent tooth surface damage. Active ingredients are often used to enhance the antibacterial, anti-caries and enamel repair effects.
2. Characteristics of Abrasive Composition
Imported tooth polishing pastes usually use micron-level or even nano-level abrasives to balance cleaning effects and tooth tissue protection. Common abrasives include:
Aluminum Hydroxide : It has uniform particles and moderate hardness. It can effectively remove stains while causing less wear on tooth enamel.
Calcium Carbonate : It has good grinding performance, stable chemical properties and relatively economical price.
Silica (Silicon Dioxide) : With its high hardness and good dispersibility, it improves the polishing effect.
Dicalcium phosphate : It not only has a polishing effect, but also can replenish minerals for teeth and play a good repair function.
The particle size and hardness of the abrasive are important indicators for evaluating the performance of polishing paste. Imported products usually use abrasive particles that have been strictly screened and surface treated to ensure effective cleaning without causing excessive wear of the tooth enamel.
3. Binder and Matrix Components
The binder is mainly a component that ensures that the abrasive is evenly dispersed and the paste is stable. Common ones are:
Hydroxyethyl Cellulose : A commonly used natural polymer thickener with good adhesion and film-forming properties.
Polyvinylpyrrolidone (PVP) : A water-soluble polymer that helps improve the stability and lubrication properties of polishing paste.
Glycerol : acts as a lubricant and humectant, increasing comfort during polishing and preventing dryness of the mouth.
The combination of these ingredients ensures that the polishing paste has appropriate fluidity and adhesion, and effectively cooperates with the mechanical action of the abrasive.
4. The role of lubricants and thickeners
Lubricants can reduce friction during polishing and protect teeth and polishing equipment. Common lubricants used in imported polishing pastes include:
Mineral Oil : has good lubrication effect and chemical stability.
PEG (polyethylene glycol) series : highly hydrophilic and can adjust the viscosity and fluidity of the paste.
Thickeners ensure the appropriate consistency of the paste and prevent the abrasive from settling or separating. Common ones include:
Carbomer : A synthetic polymer that effectively thickens and imparts a good feel.
Xanthan Gum : A natural polysaccharide with good thickening and stabilizing effects.
Reasonable ratio of lubricant and thickener improves the operating performance and user experience of polishing paste.
5. Functional expansion of active ingredients
Special active ingredients are added to some imported medical polishing pastes to enhance the functionality of the product:
Fluoride : Common sodium fluoride or stannous fluoride, helps to enhance the acid resistance of tooth enamel and prevent tooth decay.
Antibacterial agents : such as Triclosan, which reduce plaque formation and promote oral hygiene.
Mineral supplements : such as hydroxyapatite microparticles, which promote micro-repair and remineralization of tooth enamel.
Vitamin E and natural plant extracts : added to some products to reduce gum irritation and improve comfort.
The introduction of these active ingredients reflects the trend of polishing pastes shifting from simple mechanical cleaning to multifunctional oral care products.
6. Quality Control and Safety of Imported Polishing Pastes
Imported tooth polishing pastes follow strict international standards in ingredient selection and production processes. All raw materials must meet medical grade requirements to ensure that they are non-toxic and harmless. Quality control during the product production process covers raw material inspection, particle uniformity testing, microbial limit inspection, and packaging sealing testing. When used clinically, the abrasive performance of the polishing paste and its safety to tooth enamel are important assessment indicators. Imported products usually pass multiple biocompatibility and toxicology assessments to ensure their safety for long-term use.
7. Effect of ingredients on polishing effect and oral health
The fine particle size and appropriate hardness of the abrasive can effectively remove pigments and plaque, restoring the natural luster of teeth without causing micro-damage to the enamel. Binders and lubricants ensure that the paste is evenly distributed during the polishing process, reducing the burden of mechanical friction on the teeth. The active ingredients enhance the protective ability of teeth through chemical mechanisms, such as the remineralization effect of fluoride and the prevention of plaque formation by antibacterial ingredients, thereby promoting overall oral health.
Imported polishing paste not only ensures good polishing effect, but also pays more attention to the protection of oral soft and hard tissues, as well as improving the comfort of patients to meet diverse clinical needs.
8. Future Development Trends
With the development of nanotechnology and biomaterials, medical tooth polishing pastes in the future will use more nanoparticles and functional bioactive substances to achieve more precise polishing and more comprehensive oral protection. In addition, environmental protection and sustainable production have gradually become the focus of research and development, and green and harmless formulas will become a new direction.
Beauty Encyclopedia Tips:
The ingredient design of medical tooth polishing paste directly affects its clinical effect and safety. Selecting products with appropriate grinding fineness and balanced formula can effectively improve the quality of oral care and reduce irritation to teeth and gums. Patients should follow the guidance of professional doctors when using it and reasonably choose polishing products suitable for their own oral conditions.
