Dental Materials Used In Pulp Protection: Resin Sealants

Resin Sealants

 

Properties

These are light activated unfilled resins. Most are relatively viscous and do not set through loss of solvent. They set either by chemical or light activation.

Purpose of Use

  1. They are used as cavity primers or bonding agents with composite resins.
  2. They seal dentin more effectively after smear layer has been removed.
  3. They reduce the potential for ingress of bacteria or their by-products.

Disadvantages

They pose chemical risk to odontoblasts which outweighs their possible longer term benefits, of enhancing seal against micro leakage.
