Assessing electrical properties of oral lesions

Characterizing In Vivo Oral Lesion Impedances

Observational Dartmouth-Hitchcock Medical Center · NCT05430477

This study is testing a special device to see if measuring the electrical properties of oral lesions can help doctors tell the difference between normal, benign, and cancerous growths in patients.

What this trial studies

This study aims to differentiate between normal, benign, premalignant, and malignant oral lesions by measuring their electrical impedance using a custom device. It involves two cohorts: one with patients undergoing oral lesion biopsies and another with patients scheduled for oral cancer resection. The study will collect data on electrical impedance and create a database of in vivo spectra and images of oral lesions. The device used is designed for high precision and accuracy in measuring impedance, complying with safety standards.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with suspected cancer in the oral cavity or related areas requiring biopsy or resection.

Not a fit: Patients who have had a previous oral biopsy within the last 30 days or those with implanted electrical devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the diagnostic accuracy of oral lesions, aiding in early detection and treatment of oral cancers.

How similar studies have performed: While this approach is novel in its specific application to oral lesions, similar electrical impedance techniques have shown promise in other medical fields.
