Which restoration is recommended for optimal pulpal and gingival health in a big cavity?

The choice of a gold onlay or porcelain-fused-to-metal (PFM) restoration for a large cavity is often recommended due to several key factors that contribute to both pulpal and gingival health.

Gold onlays are known for their excellent biocompatibility, which minimizes the risk of adverse reactions in surrounding tissues. The gold material itself is inert and less likely to irritate the pulp or gingival tissues. Additionally, gold provides a strong and durable restoration that can withstand significant occlusal forces, which is crucial in large cavities where structural integrity is paramount. This durability helps prevent fractures or breakdown of the restoration, reducing the risk of secondary caries and need for further treatment.

PFM restorations also offer the advantage of strength, with the metal substructure providing durability, while the porcelain overlay allows for aesthetic qualities that can blend well with natural teeth. This combination can also support gingival health due to its smooth surface and functionality, which helps to maintain proper occlusion and distribute bite forces effectively.

A gold onlay or PFM restoration's ability to preserve tooth structure, prevent microleakage, and maintain a healthy environment for the pulp and surrounding gingival tissues makes it a superior choice for large cavities. In contrast, other
