title: Staining of light-cured aesthetic resin restorative materials by different staining media: an in vitro study.
abstract: Aesthetic restorative resins have been characterised by clinical discolouration. New light-cured anterior and posterior resins are currently available to the profession and this study investigated the in vitro colour stability at 24 hours and 7 days of ten such resins in three different staining media. Disc specimens were prepared and stained at 37 degrees C and 100 per cent R. H. and then evaluated by double blind visual assessment. All the materials undergo some staining in coffee and red wine. Coca-Cola, however, does not cause any staining of the restorative resins. Adaptic II is the most stain-resistant material and most of the staining occurs within the first 24 hours after immersion in the staining media.
