Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing periodontal diseases require professional dental examinations and specialized equipment, are inconsistent due to clinician variability, and lack awareness among patients, making them inefficient and inaccessible.
Innovation Solution
A non-invasive diagnostic test using a kit that includes a colourimetric indicator reactive to biomarkers in oral rinsing substances, allowing self-administered detection of inflammation levels through a rinse-and-compare method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If professional dental examination with metal probe insertion is used to diagnose periodontal diseases, then measurement precision of inflammation level is improved, but device complexity and ease of operation deteriorate due to requiring specialized equipment and clinician training
Solution Approach 1:
The patent replaces the mechanical probe insertion method with a chemical/biochemical detection system. Colorimetric sensors detect biomarkers (such as neutrophil elastase or other inflammatory enzymes) in oral rinsing substances, substituting the mechanical probing action with a chemical reaction-based detection method that produces visible color changes proportional to inflammation levels.
Solution Approach 2:
The patent introduces colorimetric sensors as intermediary substances that mediate between the biomarkers in oral fluid and the detection system. These sensors contain enzymes or antibody-enzyme conjugates that specifically bind to inflammatory biomarkers and catalyze color-changing reactions, serving as a bridge between the biological sample and the measurable optical signal.
2Reliability
If professional dental examination is used for periodontal disease diagnosis, then reliability of diagnosis is improved, but ease of operation deteriorates due to requiring regular visits to dentist and professional supervision
Solution Approach 1:
The patent enables patients to perform their own periodontal health monitoring at home using the colorimetric test kit. Patients collect oral rinsing substances and apply the colorimetric sensors themselves, eliminating the need for professional supervision during the actual measurement process while maintaining diagnostic reliability through standardized procedures and control mechanisms.
Solution Approach 2:
The patent incorporates preliminary calibration and control mechanisms into the test kit design. Control sensors with known biomarker concentrations are included to establish baseline color responses, allowing patients to validate their results against predetermined standards before interpretation, ensuring reliable self-diagnosis without requiring prior professional training.
3Measurement precision
If biochemical tests identifying enzymes from periodontium are used, then measurement precision of biomarkers is improved, but device complexity and ease of operation worsen due to requiring specialized equipment and training
Solution Approach 1:
The patent replaces complex biochemical instrumentation with simple colorimetric detection. Instead of using spectrophotometers or other specialized equipment to measure enzyme activity, the system uses color-changing sensors where the intensity of color development directly indicates biomarker concentration, readable by the naked eye or simple photodetectors.
Solution Approach 2:
The patent utilizes colorimetric reactions as the primary detection mechanism. Enzyme-linked immunosorbent assay (ELISA) or similar colorimetric methods are employed where specific enzymes or antibody-enzyme conjugates produce visible color changes in proportion to the concentration of target biomarkers, making complex biochemical information visually accessible without specialized equipment.
