Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment for detecting oral diseases using optical sensors?

Research shows that optical diagnostic tools, like fluorescence spectroscopy, are effective in detecting early signs of oral diseases. These tools are non-invasive, provide real-time results, and have been shown to accurately identify oral lesions, which can help in early diagnosis and treatment. ^{1 2 3 4 5}

Is the optical sensor detection for oral diseases safe for humans?

The optical sensor detection methods for oral diseases are generally considered safe as they are non-invasive, do not use harmful radiation, and are designed to be patient-friendly. ^{2 3 5 6 7}

How is the Optical Sensor Detection for Oral Diseases treatment different from other treatments for oral diseases?

This treatment is unique because it uses optical sensors to detect oral diseases noninvasively, providing real-time, high-resolution images without the need for ionizing radiation. It offers a patient-friendly and repeatable method that can quickly identify changes in oral tissues, potentially improving early diagnosis and management of oral conditions. ^{2 4 8 9 10}

What is the purpose of this trial?

Overall objective of this work is to develop better ways of detecting, diagnosing and measuring oral diseases and structures using light and optical approaches. All different areas of the mouth will be imaged, including healthy, diseased, dysplastic and malignant, as well as oral biofilm, and the imaging data compared against conventional diagnostic approaches such clinical and histopathological and molecular evaluations to (1) gain a better understanding of processes involved in oral pathology and (2) develop a combined patient specific, non-invasive method for the detection, diagnosis and screening of oral pathology and biofilm. Thus our goal is to identify and evaluate microstructural, metabolic, vascular, protein, genomic and metabolomics biomarkers of oral pathology can be used to detect, predict and map oral pathology, especially neoplasia. We are recruiting patients with a wide range of oral conditions including plaque, dry mouth, toothache, root canal treatments, gum disease, oral sores, dysplasia and cancer, autoimmune conditions and others as well as healthy control subjects. We will use a range of non-invasive imaging modalities to obtain information on the ways in which the oral health status affects optical properties, and determine means of detecting and quantifying these factors.. Imaging modalities to be utilized include: 1. Coherence and Doppler Tomography 2. Laser Speckle Imaging 3. Various forms of Spectroscopy 4. Fluorescence

Findings from Research

A portable spectroscopy device was tested on 79 oral sites from 33 subjects, including 28 patients with oral lesions, showing high accuracy in identifying oral cancer with an area under the curve (AUC) of 0.90 for nonkeratinized sites.

The device also demonstrated good efficacy for keratinized sites, with an AUC of 0.83, indicating its potential as a noninvasive tool for early oral cancer diagnosis.

Emerging optical diagnostic tools for the oral cavity offer non-invasive, radiation-free, and patient-friendly options for detecting and diagnosing early diseases, which is crucial as the focus shifts towards disease prevention and reversal.

These technologies provide real-time, high-resolution imaging of both soft and hard tissues, making them valuable for diagnosing oral mucosal lesions and dental pathologies.

In a study of 25 patients with oral potentially malignant disorders (OPMDs), toluidine blue staining demonstrated higher sensitivity (91%) and accuracy (75%) compared to the autofluorescence evaluation with GOCCLES®, which had a sensitivity of 66% and accuracy of 53%.

Both diagnostic methods, while effective in identifying dysplastic areas, cannot reliably differentiate between benign and malignant lesions, highlighting the need for further histopathological analysis after initial screening.
