Polyphosphate Zinc Potassium Oral Composition for Tooth Whitening and Enamel Strengthening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth whitening methods using hydrogen peroxide cause irritation and weaken tooth strength, while attempts to strengthen teeth with polyphosphates can lead to demineralization due to chelate formation with calcium ions.
Innovation Solution
A composition comprising potassium ions, an organic zinc compound, and a polyphosphate, which works to improve dentin hypersensitivity, strengthen tooth enamel, and maintain an excellent whitening effect by stabilizing the zinc salts and preventing chelate formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If hydrogen peroxide is used for tooth whitening, then whitening effect is improved, but tooth strength deteriorates and irritation occurs
Solution Approach 1:
The patent changes the chemical composition parameters by replacing hydrogen peroxide with a combination of polyphosphate, zinc compound, and potassium ion. This parameter substitution maintains the whitening function while eliminating the harmful effects on tooth strength and causing irritation to oral tissues.
Solution Approach 2:
The patent extracts and removes hydrogen peroxide from the tooth whitening composition, replacing it with alternative ingredients that provide whitening effects without the side effects of peroxide-based systems.
2Strength
If polyphosphate is used to strengthen teeth, then tooth strength is improved, but demineralization occurs due to chelate formation
Solution Approach 1:
The patent introduces zinc compounds as intermediary substances that work synergistically with polyphosphate. The zinc compound acts as a mediator that prevents the harmful chelate formation between polyphosphate and calcium ions, while still allowing polyphosphate to perform its tooth-strengthening function.
Solution Approach 2:
The patent creates a composite formulation combining polyphosphate, zinc compound, and potassium ion. This composite material approach allows the components to work together synergistically, where the zinc compound protects against demineralization while polyphosphate strengthens the tooth structure.
3Illumination intensity
If low molecular weight polyphosphate is used for whitening, then whitening effect is improved, but tooth strength deteriorates due to chelate formation
Solution Approach 1:
The zinc compound serves as an intermediary that prevents harmful chelate formation between polyphosphate and calcium ions, allowing the polyphosphate to maintain its whitening effectiveness without compromising tooth strength.
Solution Approach 2:
The patent modifies the molecular weight parameter of polyphosphate to high molecular weight, which reduces its ability to form harmful chelates with calcium ions while maintaining its whitening and anti-staining properties.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively improves dentin hypersensitivity, strengthens tooth enamel, and maintains an excellent whitening effect, addressing the issues of tooth weakening and irritation associated with hydrogen peroxide-based methods.
Implementation Method 1
most methods employ high concentrations of hydrogen peroxide to oxidize the staining agents on the teeth to bleach the teeth
Implementation Method 2
The fluorine strengthens the teeth by remineralizing hydroxyapatite on the tooth surface into fluorapatite through an ion exchange reaction between the hydroxy groups and the fluoride ions
Implementation Method 3
low molecular weight polyphosphates may form chelates with dissolved calcium on the tooth surface or form chelates with supersaturated calcium in the saliva, which can cause demineralization of the teeth
