Tooth Sensitivity Treatment via Calcium Precipitate Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tooth sensitivity treatments, such as those containing potassium nitrate and bio-glass, are not completely effective in mitigating dentinal sensitivity due to inadequate occlusion of dentinal tubules, which is dependent on various variables and does not provide a consistent solution for exposed dentin.
Innovation Solution
A composition comprising specific compounds like potassium titanium oxide oxalate, which forms a precipitate with calcium on the teeth, effectively occluding dentinal tubules and reducing sensitivity, with at least 30% of the precipitate remaining after sonicating, and is applied for at least two consecutive applications spaced no more than 12 hours apart or in the presence of calcium for at least 10 seconds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional occluding agents like potassium nitrate and bio-glass are used, then tooth sensitivity treatment is provided, but effective occlusion of dentinal tubules is not achieved
Solution Approach 1:
The patent changes the chemical parameters by using compounds with specific formulas (Formula I and Formula II) that have different chemical properties from conventional agents. These compounds form stable precipitates with calcium that effectively occlude dentinal tubules, resolving the contradiction between treatment effectiveness and occlusion precision.
Solution Approach 2:
The invention uses composite material systems where the active compounds (Formula I or II) work synergistically with calcium to form precipitate deposits. This composite approach creates a more effective occlusion mechanism than single-agent conventional treatments, simultaneously improving reliability and occlusion precision.
2Duration of action of moving object
If occluding agents are applied to dentinal tubules, then sensitivity relief is achieved, but the occlusion is not stable and does not last
Solution Approach 1:
The compounds in the invention perform preliminary action by forming stable precipitates with calcium that create lasting occlusion. The precipitate formation occurs during the application process itself, creating a stable barrier before exposure to oral conditions, thereby extending the duration of sensitivity relief and improving occlusion stability.
Solution Approach 2:
The invention utilizes phase transition from soluble compound to insoluble precipitate. The compounds (Formula I or II) transition from dissolved state in the composition to solid precipitate deposits on the dentin surface, creating stable and long-lasting occlusion that resists dislodgement and maintains effectiveness over time.
3Quantity of substance
If precipitate formation is increased to improve occlusion, then more material remains on teeth, but the composition becomes less stable
Solution Approach 1:
The patent optimizes chemical parameters including pH (adjusted to specific ranges), ionic strength, and compound concentration to control precipitate formation. These parameter changes ensure that sufficient precipitate forms for effective occlusion while maintaining composition stability and preventing premature precipitation during storage or application.
