Assessment of curing behavior of light‐activated dental composites using intensity correlation based multiple reference optical coherence tomography

Monitoring the curing kinetics of light‐activated resin is a key area of research. These resins are used in restorative applications and particularly in dental applications. They can undergo volumetric shrinkage due to poor control of the depth dependent curing process, modulated by the intensity and duration of the curing light source. This often results in the formation of marginal gaps, causing pain and damage to the restoration site. In this study, we demonstrate the capabilities of a correlation method applied using a multiple references optical coherence tomography (MR‐OCT) architecture to monitor the curing of the resin.
