Can IRM be used as a base?
IRM may also be used as a base under cements and restorative materials that do not contain resin components, such as amalgams, and inlays and onlays. Its strength properties approach those of zinc phosphate cement. IRM has excellent abrasion resistance, good sealing properties and low solubility.
Is IRM sedative?
If you have a rather large cavity, you can remove the bulk of the decay and place an “IRM” filling (Intermediate Restorative), also known as a sedative filling. This will often slow or stop the progression of decay and help the patient feel better.

Can you leave IRM under composite?
Can IRM be used as root canal sealer?

Filling the cavity. The American Academy of Pediatric Dentistry (AAPD) recommends using a direct pulp cap only on a primary tooth when exposure results from mechanical trauma. If exposure results from decay removal, indirect pulp capping, or a pulpotomy — the partial removal of pulp — is performed instead.
Can I use Dycal under composite?
Further studies are necessary to suggest that Dycal can be used without any inhibitions under composite resin restorations, may be in vivo studies with long-term follow-up of the outcome are required.
What happens if a root canal filling falls out?
If a filling falls out, see your dentist as soon as possible. Waiting too long to get the filling replaced can cause tooth decay and further problems. Keep the area clean until you can see your dentist and try to limit eating or chewing on the affected area.
