The effect of air-polishing abrasives on wear of direct restoration materials and sealants.

Background: Air-polishing devices (APDs) effectively remove supragingival staining. However, the use of APDs on restorative surfaces may result in clinically relevant surface damage and material loss.

Methods: The authors made plane specimens (N = 180) of dental restorative materials (Tetric EvoCeram [Ivoclar Vivadent, Schaan, Liechtenstein], Tetric Flow [Ivoclar Vivadent ], Grandio Flow [VOCO, Cuxhaven, Germany], Admira Seal [VOCO], Grandio Seal [VOCO]) and Ionofil Molar [VOCO]).
