| Outline of Final Research Achievements |
Optical coherence tomography (OCT) can obtain tomographic images of biological structures non-invasively, and is expected to be introduced as a clinical tool to dentistry. Using the OCT images of composite resin restorations obtained in this study, we reported that OCT can be used to evaluate the adaptation of these restorations efficiently.
The loss of adaptation "gaps" may be caused by the polymerization shrinkage immediately after polymerization of the composite. In addition to direct fillings, the adaptation of indirect restorations can be investigated using SS-OCT. In this project, we developed a software that could process OCT images and detect gaps or defects.
