Early stage dental caries detection using near infrared spatial frequency domain imaging

Abstract Early stage dental caries can be remineralized without the need for “drill-and-fill” treatments that are more invasive and less permanent. However, early stage caries lesions typically present as a white spot on a white background, resulting in many lesions only being identified after they...
