Evaluation of enamel dental restoration interface by optical coherence tomography

Evaluation of molar dental restorations on enamel is performed using optical coherence tomography ( OCT ) with 10 mu m resolution. Images of similar to 50 mu m failure gaps in the restorations are demonstrated and the OCT images are compared with x- ray and optical microscopy pictures. The results demonstrate the potential of the technique for clinical evaluation of dental restorations. (C) 2005 Society of Photo-Optical Instrumentation Engineers.
