Paper Fluidic Device for Regular Monitoring of Oral Health
Abstract

The patent describes a paperfluidic device tailored for regular monitoring of oral health. This device utilizes a simple, inexpensive, and disposable design that incorporates at least one layer of patterned hydrophobic paper printed with various reagents for detecting pH levels, microorganisms, analytes, or enzymes. This innovative tool enables quick, sensitive, and accurate assessments of oral health, suitable for use at home or in low-resource settings, providing a practical alternative to traditional dental diagnostics methods.

Problem Statement

Traditional methods for monitoring oral health, such as visual inspections, dental probes, and x-rays, often fail to detect early stages of dental issues like caries, are costly, time-consuming and require visits to dental professionals.

Uniqueness of the Solution
  • Innovative material use and design: The device utilizes a hydrophobic patterning on paper to create distinct regions for sample addition and analysis, which is essential for guiding the fluid precisely through the test zones without the need for external pumps or equipment. 
  • Advanced diagnostic features: Integrated reagents capable of detecting pH levels, microbial presence, and specific analytes related to oral health, which help in diagnostics, directly on the paper substrate, enhancing the device's capability to deliver rapid and accurate results. 
  • Ease of use and accessibility: Designed for simplicity, the device is both user-friendly and disposable. Its low-cost production and ease of use empower individuals to manage their oral health proactively at home. 
  • Environmental consideration: The choice of materials and the disposable nature of the device are balanced by environmental considerations. The device is designed to be biodegradable, minimizing its ecological footprint post-use.
Prototype Details

The prototype consists of a layered assembly where each layer is precisely fabricated to interact seamlessly with the others. The hydrophobic regions are strategically printed to manage the flow and interaction of biological samples with reactive agents, proving the concept through effective demonstration of its functionality in detecting and evaluating oral health conditions.

Current Status of Technology

The proof-of-concept of the paper fluidic device for monitoring oral health by users at home has been developed and tested with saliva samples. Initial testing has demonstrated its effectiveness in providing quick, sensitive, and accurate diagnostics for oral health, including pH and microorganism detection.
