| Research Abstract |
Optical coherence tomography(OCT) is noninvasive imaging modality which enables cross-sectional tomographic visualization of internal structure without radiation dose. The purpose of this study was to utilize the OCT for the non-destructive examination of dental restorations and for the diagnosis of caries. Internal defects and marginal gaps within the composite resin restorations were evaluated non-destructively in tomograms. Carious lesions of extracted teeth were detected using OCT. Within the limitation of our study, it is suggested that the OCT is a promising imaging modality for non-destructive examination of composite resin restoration and for the detection of carious lesion.
