In a survey of dentists practicing in eight states, it was found that polysulfide is used by 35.8% of them for cast restorations. Polyether and hydrocolloid are the second most used materials; silicone putty/reline and double mix standard silicone follow. Epinephrine cord was chosen for gingival retraction by 73.3% of the respondents. Nonepinephrine cord is used by 23.5% of the dentists who responded.
