What does IRM mean in dentistry?
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.
What is an IRM filling?
Zinc oxide-eugenol cement (IRM) is a low-strength base used as a temporary cement filling in the event that the patient will return at a later date for a semi-permanent restoration. The powder is mainly zinc oxide and the liquid is eugenol with olive oil as a plasticizer.
What is IRM made of?
IRM® Caps™ intermediate restorative material powder is composed of zinc oxide and PMMA powder (polymer reinforced). The liquid is eugenol with acetic acid added. IRM® is a reinforced zinc oxide-eugenol composition for intermediate restorations lasting up to one year.
Why is IRM used in pulpotomy?
Intermediate restorative material (IRM), which is a reinforced zinc oxide eugenol, is used widely for the dressing of the pulpal floor following root canal filling in primary teeth [11–14].
Can IRM be used for Pulpotomy?
Results. Among the 608 teeth (338 patients) treated in a single session with IRM full pulpotomy and stainless steel preformed crowns, 263 (143 patients) were evaluated after a median follow-up period of 24 months. Overall, 89% of the pulpotomies were effective, 7.6% were of uncertain outcome, and 3.4% were ineffective.

What is Apexogenesis and apexification?
Apexification is a method of inducing a calcified barrier at the apex of a nonvital tooth with incomplete root formation. Apexogenesis refers to a vital pulp therapy procedure performed to encourage physiological development and formation of the root end.
What is the difference between MTA and calcium hydroxide?
MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping material, showed higher success rate with favorable outcomes in maintaining long term tooth vitality and easier to use in pulp capping. MTA is less toxic, less pulpal inflammation capping compared to Calcium Hydroxide.
