Triple Polymer Fluoride System for Dental Erosion Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral care compositions are inadequate in preventing dental erosion and tooth wear, as they fail to effectively enhance the efficacy of fluoride ions in combating these issues, despite the presence of polymers like xanthan gum and carboxymethyl cellulose, which are known to provide some protection against demineralization.
Innovation Solution
A triple polymer system comprising xanthan gum, carboxymethyl cellulose, and copovidone, in conjunction with a source of fluoride ions, is used to enhance fluoride retention at the tooth surface, increasing remineralization and acid resistance, thereby providing better protection against dental erosion and tooth wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluoride ions are used alone to combat dental erosion, then some protection against demineralization is provided, but the efficacy is insufficient to fully prevent tooth wear and erosion
Solution Approach 1:
The patent combines fluoride ions with a triple polymer system (xanthan gum, carboxymethyl cellulose, and copovidone) to create a composite oral care composition. This composite approach allows the polymers to form a protective matrix that enhances fluoride retention and delivery to the tooth surface, thereby improving the overall reliability of protection against dental erosion beyond what fluoride alone can achieve.
Solution Approach 2:
The triple polymer system acts as an intermediary between the fluoride ions and the tooth surface. The polymers form a protective layer that facilitates fluoride adhesion and controlled release, enhancing the effectiveness of fluoride in preventing demineralization and tooth wear without directly providing protection themselves.
2Reliability
If polymers like xanthan gum and carboxymethyl cellulose are added to enhance protection, then some improvement in demineralization resistance is achieved, but the overall protection against tooth wear remains inadequate
Solution Approach 1:
The patent merges three different polymers (xanthan gum, carboxymethyl cellulose, and copovidone) with fluoride ions in a single oral care composition. This combination creates synergistic effects where each polymer contributes unique properties that collectively enhance both demineralization resistance and tooth wear protection, achieving comprehensive protection that neither polymers nor fluoride alone can provide.
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 triple polymer system significantly increases the effectiveness of fluoride ions in preventing dental erosion and tooth wear, re-hardening enamel, and reducing susceptibility to acid-mediated damage, while also combating dental caries.
Implementation Method 1
The triple polymer system helps retain fluoride at the tooth surface thereby increasing the remineralisation of teeth
Implementation Method 2
the triple polymer system helps retain fluoride at the tooth surface thereby increasing the remineralisation of teeth and increasing the acid resistance of teeth, so providing a better surface protection against the effects of dental erosion
