Preference of temporary restorations and spacers: a survey of Diplomates of the American Board of Endodontists.

The purpose of this investigation was to survey Diplomates of the American Board of Endodontists to determine their preferences in temporary restorations used during and following endodontic therapy and if cotton pellets are used as spacers. The survey asked which primary temporary material was used in anterior and posterior teeth to close access openings. Also, the endodontists were asked if they preferred a double seal and if they used cotton pellets as spacers.
