What is silex (Silicone Dioxide) primarily used for in dental applications?

Silex, or silicone dioxide, is primarily utilized in dental applications as an abrasive due to its effective capabilities in addressing heavy stains on dental surfaces, particularly in polishing and cleaning procedures. Its hardness and gritty texture allow for the effective removal of stubborn deposits and stains, which can be particularly beneficial when working with restorative materials or natural teeth that have accumulated extrinsic discoloration.

In polishing techniques, it acts as an efficient abrasive because it can work through tough stains without overly damaging the underlying tooth structure or restorative materials. This makes it a popular choice in polishing agents and dental cleaning pastes designed for more intense stain removal.

Options that suggest uses such as enhancing color or providing a smooth finish do not align with the primary function of silex. While it can contribute to a polished appearance indirectly by effectively removing stains, its main role remains that of a polishing abrasive, especially for surfaces that require more aggressive cleaning techniques.
