RadiologyRadiographic detection of carious lesions or dentinal destruction typically requires a certain threshold of loss of tooth structure. Studies have shown that a loss of approximately 40 microns of dentin is necessary for a radiograph to show evidence of carious lesions.

Conservative DentistryThe discoloration of amalgam restorations is often due to the formation of silver sulfide on the surface, which can occur due to the reaction of silver with sulfur compounds in the oral environment. The gamma I phase is a strong component of amalgam, while the gamma II phase is weaker and less stable. Oxides can form as well, but sulfides are more directly associated with the discoloration observed in clinical settings.
