Resin composite polishing - Filling the gaps

Objective: The search for the ideal polishing agent for resin composite mat erials is still ongoing. A new polishing brush with abrasive bristles for p olishing resin-based restorations was tested to determine if if polishes re storations, including those with concave surfaces, macrostructured occlusal surfaces, and textured surfaces, without destroying their delicate texture or microstructure. Method and materials: The polishing effectiveness and t he ultimate destructive potential of these brushes were assessed quantitati vely and subjectively in vitro In addition, the durability of the brushes a fter repeated use and autoclaving was also evaluated. Results: The brushes were nondestructive to resin-based restoratives, enamel, dentin, and the re storation interface. They produced a shiny surface on resin-based restorati ve materials without destroying the surface texture, The abrasive brushes w ere autoclavable and demonstrated satisfactory durability, despite multiple heat sterilization cycles. Conclusion: These brushes can be considered to be key products to polish concave surfaces, anatomically shaped occlusal su rfaces, and textured surfaces without damaging the surface characteristics.
