Which polishing paste is recommended for use on filled hybrid composites and resin restorations?

The recommended polishing paste for use on filled hybrid composites and resin restorations is aluminum oxide. This choice is particularly appropriate due to its fine crystalline structure, which allows for effective polishing without causing damage to the restorative material.

Aluminum oxide particles are specifically designed to achieve a high-quality finish on soft dental materials while minimizing the risk of scratching or compromising the integrity of the restoration. Their durability ensures they can withstand the pressures applied during the polishing process, making them suitable for this type of dental work.

In contrast, other substances, such as calcium carbonate or sodium bicarbonate, tend to be too abrasive for immediate use on these specific dental materials and are typically reserved for other types of cleaning applications. Silica, while also a commonly used polishing agent, may not provide the same level of control and effectiveness on filled composites and resin restorations as aluminum oxide does. Therefore, aluminum oxide stands out as the most appropriate choice for achieving a smooth, polished finish on these specific materials.
