This question was submitted to us by a general dentist: What kind of restoration material is best recommended for root caries, especially where isolation is a problem?
Dr. Jacinta Santos, Assistant Professor of Restorative Dentistry, Schulich School of Dentistry at Western University, has provided this quick initial response.

In a root caries procedure, lack of dentin and poor isolation may present restoration challenges. Resin-modified glass-ionomer (RMGI) is a restorative material that can be used effectively in this situation.
Clinical studies have demonstrated that RMGIs:
- Have very good retention over time (due it’s chemical and mechanical adhesion)
- Present low polymerization shrinkage
- Is less adversely affected by moisture
- Release fluoride to the dental structure
