Simon JC, Darling CL, Fried D.
PMID: 27006524
Proc SPIE Int Soc Opt Eng. 2016 Feb 13;9692. doi: 10.1117/12.2218656. Epub 2016 Feb 29.

Clinicians need technologies to improve the diagnosis of questionable occlusal carious lesions (QOC's) and determine if decay has penetrated to the underlying dentin. Assessing lesion depth from near-infrared (NIR) images holds great potential due to the high transparency of...

Assessment of cavitation in artificial approximal dental lesions with near-IR imaging.

Simon JC, Darling CL, Fried D.
PMID: 28626283
Proc SPIE Int Soc Opt Eng. 2017 Jan 28;10044. doi: 10.1117/12.2256701. Epub 2017 Feb 08.

Bitewing radiography is still considered state-of-the-art diagnostic technology for assessing cavitation within approximal carious dental lesions, even though radiographs cannot resolve cavitated surfaces but instead are used to measure lesion depth in order to predict cavitation. Clinicians need new...

Attenuation of near-IR light through dentin at wavelengths from 1300-1650-nm.

Light scattering in dental enamel decreases markedly from the UV to the near-IR and recent studies employing near-IR transillumination and reflectance imaging including optical coherence tomography indicate that this wavelength region is ideally suited for imaging dental caries due...

High contrast optical imaging methods for image guided laser ablation of dental caries lesions.

Proceedings of SPIE--the International Society for Optical Engineering

Lamantia NR, Tom H, Chan KH, Simon JC, Darling CL, Fried D.
PMID: 24791129
Proc SPIE Int Soc Opt Eng. 2014 Feb 18;8929. doi: 10.1117/12.2045683.

Laser based methods are well suited for automation and can be used to selectively remove dental caries to minimize the loss of healthy tissues and render the underlying enamel more resistant to acid dissolution. The purpose of this study...

Transillumination and reflectance probes for .

Proceedings of SPIE--the International Society for Optical Engineering

Simon JC, Lucas SA, Staninec M, Tom H, Chan KH, Darling CL, Fried D.
PMID: 24817803
Proc SPIE Int Soc Opt Eng. 2014 Feb 18;8929:89290D. doi: 10.1117/12.2045630.

Previous studies have demonstrated the utility of near infrared (NIR) imaging for caries detection employing transillumination and reflectance imaging geometries. Three intra-oral NIR imaging probes were fabricated for the acquisition of

Infrared Methods for Assessment of the Activity of Natural Enamel Caries Lesions.

IEEE journal of selected topics in quantum electronics : a publication of the IEEE Lasers and Electro-optics Society

IEEE J Sel Top Quantum Electron. 2016 May-Jun;22(3). doi: 10.1109/JSTQE.2016.2542481. Epub 2016 Mar 15.

New diagnostic methods are needed for the accurate assessment of caries lesion activity to establish the need for surgical treatment. Detection of the highly mineralized surface layer that forms near the surface of the lesions as a result of...

Assessment of remineralization in simulated enamel lesions via dehydration with near-IR reflectance imaging.

Proceedings of SPIE--the International Society for Optical Engineering

Lee RC, Darling CL, Fried D.
PMID: 25914494
Proc SPIE Int Soc Opt Eng. 2015 Feb 24;9306. doi: 10.1117/12.2083655.

Previous studies have demonstrated that near-IR imaging can be used to nondestructively monitor the severity of enamel lesions. Arrested lesions typically have a highly mineralized surface layer that reduces permeability and limits diffusion into the lesion. The purpose of...

PMID: 21998493
Proc SPIE Int Soc Opt Eng. 2009 Jan 01;7162. doi: 10.1117/12.816865.

Previous studies have demonstrated that polarization sensitive optical coherence tomography (PS-OCT) can be used to image natural root caries lesions, measure non-destructively the severity of dentin demineralization and determine the efficacy of intervention with anti-caries agents including fluoride and...

Near-IR Polarization Imaging of Sound and Carious Dental Enamel.

Proceedings of SPIE--the International Society for Optical Engineering
