Early Caries Detection Using Optical Coherence Tomography

Successful therapeutic interventions targeting early caries in children require assessment of the early lesion and underlying biological disease. The goal of this research is: validating a novel near infrared (NIR) imaging technology, available for clinical practice in 2010-2011, to image and monitor incipient enamel carious lesions; and determining changes of the bacterial profile in the plaque while monitoring caries activity. The goal of this research is to determine if NIR imaging can be used as an adjunct to the AAPD Caries Assessment Tool (CAT) to help diagnose early occlusal and smooth surface lesions. In addition, this project will monitor the bacterial profile in the plaque during early lesion progression, to determine if certain profiles are more predictive of the rate of decay. The project requires the use of MATLAB for post-image processing and analysis of the images.
