Rubber Cup Polishing
A technique using a rotating rubber prophylaxis cup loaded with an abrasive paste to remove extrinsic stain and residual soft deposits from tooth surfaces.
Full Definition
Rubber cup polishing is performed with a low-speed handpiece fitted with a disposable or reusable rubber cup, in conjunction with a prophylaxis paste of varying abrasivity (measured by Relative Dentine Abrasivity, or RDA). It is primarily indicated for removal of extrinsic stain after supragingival deposit removal rather than as a universal polishing step. Contemporary evidence-based dental hygiene practice advocates selective polishing — applying rubber cup polishing only where stain is clinically present — to minimise unnecessary removal of the fluoride-rich outer enamel layer. Editors should note that 'rubber cup polishing' and 'coronal polishing' are often used interchangeably but coronal polishing is the broader, scope-of-practice term used in regulatory documents.
Usage
Usage note: Distinguish from 'coronal polishing', which is the credentialed scope-of-practice term. In regulatory or legislative documents, 'coronal polishing' is preferred.
