![]() The dimensional accuracy results (%) were subjected to analysis of variance. Surface detail reproduction and dimensional accuracy were evaluated using optical microscopy on the 50-μm wide line, which was 25 mm in length, according to ISO 1563 standard. The molds were filled with dental plaster (Durone IV). The molds were removed 2 minutes after loss of sticky consistency and either filled immediately or stored in closed jars at 100% relative humidity and 37☌ for 1, 3, or 5 days. The molds were prepared over a matrix containing 50-μm line, (ISO 1563 standard) under pressure with a perforated metal tray. All alginates are packaged in 500 g poly-aluminum pouches to increase shelf life and reduce storage space requirements.This study compared the surface detail reproduction and dimensional accuracy of stone models obtained from molds prepared using different alginate impression materials (Cavex ColorChange, Hydrogum 5, or Jeltrate Plus) and with different storage times (1, 3, and 5 days) to models from molds that were filled immediately with no storage time. Image™ Dust-Free mint scented alginate offers easy mixing, excellent stone surface, unsurpassed smoothness and fine detail.
