Polytetrafluoroethylene for interim restoration of post spaces

Bacterial recontamination of the empty space is of concern in the time between the post space preparation and cementation of a cast post-and-core. This dental technique describes a novel treatment approach with sterilized polytetrafluoroethylene tape and a reinforced zinc-oxide eugenol restorative material to maintaining asepsis of the root canal space while awaiting fabrication and delivery of a cast post-and-core. On delivery of the cast post-and-core, the material can be removed with minimal time and effort.
