directly to enamel, dentin, cementum, and stainless
steel. Releases fluoride. Ex: Vitrebond
Liners Thin layers of material used to protect the pulp, aid in its
recovery, or both.
IRM IRM material is zinc oxide Eugenol with polymer reinforcement.
(Intermediate Restorative
Material)
Most common for inlay/onlay preps. Will stick to
adjacent teeth. You can roll into a ball, put into prep,

have patient bite down. You want the material to stick
to the
adjacent teeth but not to the papilla so always make
sure to check and clean interproximal excess.
Temporary filling material that hermetically deals in
Cavit
medicaments while sealing out saliva. Most common
in Endo (Root Canal) procedures.
Acrylic Bis-Acryl temporary crown and bridge material. Ideal for all
