Resin Coating (RC)

A key term of biomimetic restorative dentistry, clearly defined. Part of The Hybrid Layer's free reference glossary.

Summary – What is Resin Coating (RC)?

Resin Coating (RC) is the technique by which 0.5 mm of microfilled, flowable composite is placed over the Immediate Dentin Sealing (IDS) layer. An example of an appropriate material to use for RC is Clearfil Majesty Flow by Kuraray. RC:

  • Allows more time for the dentin bond to develop and for the hybrid layer to mature and therefore contributes to the concept of Decoupling With Time (DWT)
  • Reduces the thickness of the Oxygen-Inhibited Layer
  • Forms part of the Biobase
  • Prevents transudation (movement of pulpal fluid) through the IDS layer.
