Fluorescence pH Sensor for Early Dental Caries Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental imaging and diagnostic instruments are limited in their ability to detect bacterial activity and monitor dental caries outside of a clinical setting, leading to inefficient and costly management of dental caries, particularly in early childhood caries (ECC), which disproportionately affects minority and low-income families.
Innovation Solution
Development of a device and method utilizing fluorescence-based pH sensing with optical spectroscopy and scanning fiber endoscope technology for non-invasive, intra-oral monitoring of pH changes and bacterial activity, enabling self-monitoring and remote supervision, incorporating a sugar challenge and porphyrin fluorescence measurement to assess caries risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical and restorative treatment is used for dental caries, then immediate treatment effect is achieved, but disease progression is not addressed and costs increase
Solution Approach 1:
The patent applies preliminary action by implementing early detection of dental caries through portable imaging devices and pH monitoring systems. The system detects demineralization at early stages before surgical intervention is needed, allowing preventive treatments like remineralization agents to be applied. This shifts the approach from reactive surgical treatment to proactive prevention, addressing the contradiction by catching disease early to avoid costly surgical interventions while maintaining effective treatment through monitoring and prevention protocols.
2Reliability
If professional monitoring is implemented for caries prevention, then disease progression is halted, but device complexity and accessibility are limited
Solution Approach 1:
The patent replaces complex mechanical diagnostic instruments with optical-based detection systems. Portable devices use light transmission and fluorescence detection to identify demineralization and bacterial activity, eliminating the need for complex mechanical imaging equipment. This substitution maintains monitoring effectiveness through sensitive optical detection while dramatically reducing device complexity, enabling home use and improving accessibility for at-home care protocols.
Solution Approach 2:
The patent enables self-service by designing portable monitoring devices that can be used by patients at home without requiring complex clinical equipment or professional operation. The simplified devices allow individuals to perform their own caries risk assessment and monitoring, collecting data on pH levels, bacterial activity, and enamel demineralization. This self-service capability maintains reliable monitoring while eliminating the need for complex professional diagnostic instruments, directly resolving the contradiction between monitoring effectiveness and device complexity.
3Loss of time
If early detection methods are implemented, then caries progression is prevented, but measurement precision of bacterial activity is insufficient
Solution Approach 1:
The patent employs multiple parameter measurements to achieve both early detection and high precision. The system simultaneously measures pH levels, light transmission properties, fluorescence intensity, and bacterial metabolic activity. By monitoring multiple parameters rather than relying on a single measurement, the system achieves rapid early detection while maintaining high precision in assessing bacterial activity and demineralization extent. This multi-parameter approach resolves the contradiction by providing comprehensive data that is both quickly obtained and highly accurate.

AI summary
A system for the optical measurement of pH includes a light emitter to emit an excitation light, and a detector coupled to receive florescence light produced by a compound in a mouth of a patient in response to the excitation light. A controller is coupled to the detector, and the controller includes logic that when executed by the controller, causes the system to perform operations. The operations may include emitting the excitation light from the light emitter; measuring an intensity of the florescence light emitted from a surface of individual teeth in a plurality of teeth in the mouth; and determining, based on the intensity of the florescence light, one or more locations on the individual teeth likely to develop demineralization.
