Dental crowns fabricated from modern ceramics inevitably retain tooling marks and minor crevices, especially at their cut and polished edges. Cutting fluids and other contaminants are also generally present, which can interfere with the bonding potential of the ceramic and can become biologically disadvantageous, as well as non-sterile. Radio Frequency Glow Discharge Treatment (RFGDT) is a recently introduced, novel cleaning and sterilization method for finishing ceramic crowns.
