Abstract

OBJECTIVE

To determine the effect of different retraction cord medicaments on surface detail reproduction of polyvinyl siloxane impression materials and compare this effect on any two brands of commercially available polyvinyl siloxane impression materials.

MATERIAL AND METHODS

Four stainless steel dies were made according to ADA specification no.19. Three dies were treated with aluminium chloride (5%), ferric sulphate (13.3%) and epinephrine (0.1%) while the fourth one was left untreated to serve as control. Two impression materials (Dentsply and 3M ESPE) were used.

RESULTS

All the three medicaments adversely affected the surface detail reproduction of both the brands of the polyvinyl siloxane impression materials. These effects were statistically significant as compared to untreated control. The impressions of 3M ESPE brand have shown better surface detail reproduction as compared to Dentsply impression material.

CONCLUSION

Surface detail reproduction of the polyvinyl siloxane impression materials is adversely affected by the retraction cord medicaments. The presence of moisture or any traces of the medicaments should be removed from the tooth surface to provide a dry field for the correct reproduction of the surface detail of these materials. Key words:Polyvinyl Siloxane, retraction cord medicaments, surface detail reproduction.

摘要

目的

确定不同排龈线药物对聚醚橡胶印模材料表面细节再现的影响，并比较其对两种市售聚醚橡胶印模材料的影响。

材料与方法

按照美国牙科协会第19号规范制作四个不锈钢代型。三个代型分别用氯化铝（5%）、硫酸铁（13.3%）和肾上腺素（0.1%）处理，第四个代型不做处理作为对照。使用两种印模材料（登士柏和3M ESPE）。

结果

所有三种药物均对两种聚醚橡胶印模材料的表面细节再现产生不利影响。与未处理的对照相比，这些影响具有统计学意义。与登士柏印模材料相比，3M ESPE品牌的印模表现出更好的表面细节再现。

结论

排龈线药物对聚醚橡胶印模材料的表面细节再现产生不利影响。应从牙齿表面去除水分或任何药物痕迹，以便为正确再现这些材料的表面细节提供干燥区域。关键词：聚醚橡胶、排龈线药物、表面细节再现
