Objective:

To develop a biosensor for real-time detection of oral inflammation by measuring TNF-alpha levels, which are critical for diagnosing conditions like pulpitis and periodontitis.

Approach:

Key Findings:

• The biosensor can detect small amounts of TNF-alpha and resist interference from saliva, which is crucial for accurate diagnostics.
• It maintained accuracy despite movement and stretching in the oral cavity, indicating its robustness in real-world applications.
• Dose-dependent increases in TNF-alpha were accurately detected in preclinical models, supporting its potential for early diagnosis.

Interpretation:

The findings demonstrate the feasibility of using the TAHM biosensor for real-time monitoring of oral inflammation, which could significantly enhance point-of-care diagnostics and improve patient outcomes in dental care.

Limitations:

• The study was conducted in preclinical models; further clinical validation is needed to ensure reliability in human subjects.
• Potential challenges in integrating the device into routine dental practices include clinician training and patient acceptance.

Conclusion:

The TAHM biosensor shows promise for early detection of oral inflammation, potentially improving patient outcomes in dental care.
