What is an IRM 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 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.
Can you use IRM under composite?
Related to microhardness test, IRM can be used safely underneath composite restorations or GI restorations.
What is reinforced zinc oxide-eugenol?
This cement features a reinforcing polymer incorporated into the powder. This gives the cement the strength to resist condensation forces and to ensure adequate life when used as a temporary filling.
How is IRM used?
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.
How long does zinc oxide filling last?
But how long does this filling last? From the word itself, it is meant not to last for a long period of time because it wears out more swiftly. This filling often lasts about six to eight weeks, especially if the reason of the filling is about the root canal.
What is calcium hydroxide dental?
Calcium hydroxide has a hard tissue inducing effect. It is a powder, that can be mixed with a physiological saline to a paste. The paste is highly alkaline with a pH 12.5 and its application to the pulp results in necrosis of the part of coronal pulp tissue shows no or only a milled inflammatory reaction.

When to use IRM as an intermediate restorative material?
IRM is an intermediate restorative material, composed of polymer reinforcement zinc oxide-eugenol (ZOE). IRM is recommended for many applications, including restoration of deciduous teeth (when permanent teeth are two years or less from eruption); restorative emergencies;
What kind of base is used for IRM?

The powder is mainly zinc oxide and the liquid is eugenol with olive oil as a plasticizer. Secondly, what is Cavit used for?
Which is better for teeth znoe or IRM?
IRM has been shown to be superior to conventional ZnOE cements. This study is a biotechnical investigation of IRM’s effect on the dental pulp with respect to its sealing capacity. Enamel-dentin test bodies with IRM fillings were used in the in vitro part, where insufficiencies in sealing were detect …
