What is the recommended treatment for a tooth with a significant DO amalgam and a crack in the mesial area?

The recommended treatment for a tooth with a significant distal-occlusal amalgam restoration and a crack in the mesial area is primarily to restore the structural integrity of the tooth while also providing adequate protection against further damage or fracture. A porcelain-fused-to-metal (PFM) crown is ideal in this scenario because it offers strength and durability, making it suitable for a tooth that may be compromised due to existing restorations and cracks.

PFM crowns cover the entire tooth structure, ensuring that any compromised areas are protected from additional stresses that might lead to further cracking or fracture. This is particularly important when significant restorative work has already been done, as the tooth is generally more susceptible to further damage. The biocompatible and aesthetic characteristics of PFM crowns also allow for a natural appearance, which is beneficial for patient satisfaction.

In contrast, options like composite fillings might not provide sufficient strength or support for a tooth with existing structural concerns, while dental bonding is typically used for less extensive repairs and may not be adequate for a tooth with a significant crack. Extraction is generally considered only when a tooth is non-restorable, and given that the tooth has an existing significant amalgam restoration, it suggests that there is still tooth structure present that warrants treatment rather than
