About temporary filling materials
A temporary filling material seals the access cavity during and after endodontic treatment, until the final restoration is placed, against reinfection. The commonest short-term materials are zinc oxide eugenol and zinc oxide with calcium sulfate. Zinc oxide eugenol has antimicrobial properties that make it more resistant to bacterial penetration, while the sealing of zinc oxide with calcium sulfate is explained by setting expansion and water sorption. For longer periods, more durable materials are used: glass ionomer cements, which bond chemically to tooth structure, and resin-based materials.
Meant to come out again: it holds the access cavity closed between visits. In one study none of the materials tested stopped bacterial leakage completely.
