AB  - ABSTRACT. In clinical dental practice, it is often difficult or even impossible 
      to detect and assess interfacial adhesive defects at adhesive restorations by 
      means of visual inspection or other established diagnostic methods. However, 
      nondestructive optical coherence tomography (OCT) may provide a better picture in 
      this diagnostic scenario. The aim of this study was to evaluate the suitability 
      of swept source OCT (SS-OCT) for the nondestructive assessment of interfacial 
      deficiencies at composite restorations and the evaluation of cohesive defects 
      within composite material. Ten class V composite restorations that were not 
      adhesively luted were taken as validation objects and examined for frequency of 
      interfacial gaps, air entrapments, and defects between composite layers using 
      SS-OCT with a 1325-nm center wavelength. Light microscopy was used to inspect for 
      inherent structures. SS-OCT detected 79.5%+/-1.8% of the total gap lengths at the 
      enamel interface and 70.9%+/-0.4% at the dentin interface. Additionally, defective 
      structures in composite restorations were displayed. It was shown that OCT 
      imaging has the potential to nondestructively assess the interfacial adaptation 
      of composite restorations and to detect internal defects in the layered composite 
      material.
