What can be said about the statements regarding the preparation of the intaglio surface of a casting?

In the context of dental casting, the intaglio surface refers to the inner surface of a casting that comes in contact with the tooth structure. Proper preparation of this surface is critical for the successful seating of the restoration and for ensuring adequate retention and fit.

When both statements regarding the preparation of the intaglio surface are true, it indicates that they are consistent with accepted practices and principles within restorative dentistry. This could involve techniques such as ensuring the surface is smooth, free of debris, and appropriately contouring it to match the prepared tooth. The statements might also emphasize the importance of achieving a precise fit to prevent issues such as microleakage or retention failure.

Accepting that both statements are true demonstrates an understanding of the technical processes and standards involved in dental casting preparations. Thus, the correct answer reflects a solid grasp of these essential principles in the field, ensuring optimal outcomes in restorative dentistry.
