This investigation was undertaken to study the abrasion and staining resistance of denture base and veneering resins. The abrasion of certain resins was tested with specific commercial cleaning agents and dentifrices by use of natural and synthetic bristle toothbrushes and denture brushes. Staining resistance was tested by use of natural food stains on the resins. Results indicate some general guidelines for the clinical selection, use, and maintenance of dental restorations or appliances fabricated with these resins.
