Anti-calculus Dental Composition Using Pyrophosphate and Polyphosphate Agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing dental calculus, such as mechanical scaling, are invasive, painful, and can damage healthy gum tissue, while chemical agents often cause side effects like discoloration and toxicity, and are ineffective in reaching subgingival calculus.
Innovation Solution
A composition comprising pyrophosphate and polyphosphate agents, potentially combined with alkali bicarbonate and fluoride, is applied topically to dissolve and remove subgingival calculus, using a device to deliver the solution directly to the calculus pocket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical scaling is used to remove calculus, then calculus removal effectiveness is improved, but gum tissue damage and pain occur
Solution Approach 1:
The patent replaces the mechanical scaling system with a chemical dissolution system. The composition uses pyrophosphate and polyphosphate agents to chemically dissolve calculus through chelation of calcium ions, eliminating the need for mechanical force that damages gum tissue while maintaining effective calculus removal.
Solution Approach 2:
The patent changes the chemical parameters of the oral environment by introducing specific phosphate compounds that alter the solubility equilibrium of calculus minerals. The composition modifies the chemical composition and pH parameters to create conditions favorable for calculus dissolution without mechanical intervention.
2Reliability
If chemical agents are used to prevent calculus formation, then calculus prevention is improved, but tooth discoloration and oral mucosa irritation occur
Solution Approach 1:
The patent optimizes the chemical parameters of the composition including pH control (buffered to physiological range), concentration of phosphate agents, and ionic strength to achieve calculus prevention without the side effects of earlier chemical agents. The buffered composition maintains parameters that are effective against calculus but safe for oral tissues.
Solution Approach 2:
The patent uses a composite chemical system combining pyrophosphate, polyphosphate, and buffering agents in specific proportions. This composite composition achieves synergistic effects where the combined formulation provides superior calculus prevention while the buffering components neutralize potential irritating effects on oral mucosa.
3Ease of operation
If standard mouthwashes are used for oral care, then ease of application is improved, but effectiveness in reaching subgingival calculus is reduced
Solution Approach 1:
The patent utilizes hydraulic principles by formulating the composition as a liquid or gel that can be delivered through subgingival irrigation devices. The fluid dynamics of the composition allow it to be propelled under pressure into subgingival pockets, achieving deep penetration while maintaining ease of application through simple irrigation protocols.
