TI  - 3D evaluation of composite resin restoration at practical training using 
      swept-source optical coherence tomography (SS-OCT).

AB  - Internal adaptation of restorations to the cavity wall is one of the important 
      topics in clinical dentistry. The purpose of this study was to investigate the 
      possibility to utilize the non-invasive tomographic imaging system for teaching 
      the importance of cavity adaptation at dental school pre-clinical training. 
      Swept-source optical coherence tomography (SS-OCT) was used for detection of 
      marginal and internal defects in the composite resin restorations as an 
      educational device. Class 1 and Class 2 composite restorations to melamine resin 
      molar tooth were assigned to the students and prepared during the skill test, and 
      SS-OCT imaging was performed to evaluate students' works. SS-OCT could detect the 
      internal gaps and voids within the restorations in tomography images synthesized 
      based on the backscatter signal from within the restoration. It is suggested that 
      the SS-OCT is promising diagnostic modality, as well as educational imaging 
      device for the detection of internal gaps in adhesive restorations.
