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. Eighty percent (507 of 603) of the surveys were returned. Cavit was the temporary restoration of choice for both anterior and posterior teeth, 48% and 54%, respectively. The majority of Diplomates, 83%, placed a cotton pellet beneath the temporary restorations.
