Abstract
Aim:The main purpose of this study was to compare the wettability of light and medium body consistencies of three different elastomeric impression materials during their working time.Materials and Methods:Vinylpolysiloxane, polyether, and vinylsiloxanether light body and medium body impression materials were used to fabricate the test samples. The contact angles of the impression materials were determined at 30th s from the start of mixing until their entire range of working time using a goniometer. The mean contact angles at the early stage of working time and at the end of working time for two consistencies of each impression material were subjected for statistical analysis.Results:The result showed contact angle of all the impression materials toward the end of working time was less than the early stage with the statistical significance (P < 0.05). The contact angle of the light body impression material was less than the medium body impression materials with statistical significance (P < 0.05) except for vinylsiloxanether impression material.Conclusion:We have concluded from this study that vinylsiloxanether impression materials exhibited the least contact angle followed by polyether and the highest was recorded for vinylpolysiloxane impression material.
