Which type of dental materials might an EFDA be instructed to use?

The choice of composite resins, glass ionomer, and dental amalgam accurately reflects the range of dental materials that an Expanded Function Dental Assistant (EFDA) is trained to use in a clinical setting. These materials are commonly employed in restorative dentistry for various applications.

Composite resins are versatile materials that are used for both anterior and posterior restorations due to their aesthetic properties, allowing them to blend seamlessly with natural tooth structures. Glass ionomer is valued for its chemical properties and ability to release fluoride, making it useful in areas where additional tooth protection is desired. Dental amalgam is a durable material traditionally used for posterior restorations, providing strength and longevity in areas subject to heavy chewing forces.

Using these materials aligns with the understanding that EFDAs have specialized training to assist in procedures that involve direct restorative techniques, such as placing and finishing restorations. In contrast, the other options mentioned do not encompass the broader range of materials that EFDAs are trained to work with. For example, limiting the choice to only acrylic resins and porcelain does not account for the widely used materials in both aesthetic and functional restorations, and single-material options like gold or silver restorations or dental cements do not represent the full scope of a dental assistant's responsibilities
