Dental crowns have surface pollutants after their manufacturing. We know that these pollutants can be a source of peri-implant inflammation for some cases. This study aimed to compare two dental crowns cleaning methods that are simple and quick to apply in the dental lab. To characterize qualitatively and quantitatively the pollution of transmucosal parts of zirconia monolithic crowns after supra-mucosal glazing in the lab and to compare the efficacy of steam versus ultrasonic cleaning protocols.
