Agents For Pulp Protection

Agents For Pulp Protection

Write a short note on agents for pulp protection.
Answer:

Agents for pulp protection are:

• Varnish
• Sealer
• Liner
• Base.

Varnish:  Varnish or Cavity varnish is a solution of one or more resins in a volatile solvent which when applied onto the cavity walls, evaporates leaving a thin resin film that serves as a barrier between the restoration and dentinal tubules.

Sealer: It is used to seal dentinal tubules and to treat dentin hypersensitivity. An adhesive sealer is commonly used under indirect restorations. For the application of sealer, a cotton tip applicator is used to apply sealer on all areas of exposed dentin.

Liner:  Liner or Cavity liners are cement coatings of minimal thickness that are applied to the prepared cavity when the remaining dentin thickness is adequate.

Base:  Base or cavity base is a layer of cement placed beneath a permanent restoration to encourage recovery of the injured pulp and to protect it against numerous types of insults to which it may be subjected.
