Abstract
The HygojetTM System (Dürr Dental GmbH & Co. KG, Germany) is the fast and safe cleaning and disinfection system for impression materials of all types in dental practices. The dimensional change and the surface roughness of five kinds of impression materials, that is, AROMA FINE and HI-TECHNICOL alginate impression materials, SURGIDENT hydrocolloid impression material, and XANTOPREN and EXAFLEX silicone rubber impression materials, following the treatment with this system were evaluated. The results were as follows.
1. No significant reduction was observed on the dimensional change of all kinds of impression materials.
2. No significant effect was observed on the surface roughness of all kinds of impression materials.
The results of this study indicated that HygojetTM System had no adverse effect on the dimensional change and the surface roughness of the impression materials of all types tested.
