Platinized gold foil is a combination of gold and platinum where 15% of the content is platinum. It is produced by rolling layers of gold and platinum together to achieve the desired thickness and distribution of the platinum within the gold foil. This process creates a homogeneous mixture that enhances the hardness and wear resistance of the restoration, making it suitable for high-stress areas like incisal edges and cusp tips.

Prophylactic spinal irradiation is often used in conditions like acute lymphatic leukemia and non-Hodgkin's lymphoma to prevent central nervous system involvement. However, it is not routinely used in Hodgkin's lymphoma unless there is a specific indication for it.
