Volume change in the luting gap after 5 years of artificial aging. Boxplot diagram visualizing the volume change (∆V5) in the luting gap after 5 years of professional mechanical biofilm removal (PMPR) and artificial aging for all investigated devices (RCP (rubber cup and polishing paste), LAPA-1 (air-polishing device with glycine powder) and LAPA-2 (air-polishing device with erythritol powder) and luting cements (GIZ (glass-ionomer cement) and AD (adhesive bonding) compared to the control group (no cleaning)
