Final answer:
The question is about the types of materials used in auxiliary polishing aids for teeth, such as fluoride-infused or metal-based components, which help in removing plaque and stains while promoting oral health.
Step-by-step explanation:
The question pertains to auxiliary polishing aids used in dental practices. These aids are typically used to remove plaque and stains from the surface of teeth, contributing to both oral hygiene and the aesthetic appearance of the teeth. Auxiliary polishing aids can be impregnated or coated with various substances to enhance their effectiveness. The options provided in the question—silicone-based, nylon-based, fluoride-infused, and metal-based—refer to different types of material that abrasive polishing strips may be composed of or coated with.
For example, fluoride-infused strips can aid in the remineralization of teeth enamel, combatting dental caries by incorporating small amounts of fluoride, which is a beneficial practice noted for the formation of dental enamel and bones. Metal-based strips could refer to the metal components used in certain cleaning and polishing products, which might potentially include stainless steel or nickel.
