What is an indication for using cast gold inlays?

Using cast gold inlays is particularly indicated for small carious lesions due to several advantages that this material offers. Cast gold is highly durable and resistant to wear, making it an excellent choice for restoring areas that experience significant occlusal forces, such as posterior teeth. The precise fit of an inlay helps preserve tooth structure and provides effective sealing against microleakage, which is crucial for a long-lasting restoration in cases of small carious lesions.

In contrast, other situations such as non-vital teeth may require different restorative approaches, such as crowns, to provide adequate support and longevity given the inherent limitations of the tooth. Likewise, poor plaque control and a high caries index are usually better addressed with preventive strategies or more extensive restorations rather than relying solely on cast gold inlays, which require a higher level of oral hygiene for optimal success.
