Which of the following substances promotes mineralization in dental treatments?

Mineral Trioxide Aggregate (MTA) is recognized in dental treatments for its significant role in promoting mineralization. MTA is a biocompatible material that has excellent sealing properties and stimulates various biological responses, including the deposition of mineralized tissues. It acts as a scaffold for reparative processes, encouraging the formation of hard tissue in the presence of biological fluids.

When used in procedures such as pulp capping or apexification, MTA fosters the regeneration of dental pulp tissue and subsequent mineralization at the site of application. It promotes the production of odontoblast-like cells that secrete dentin matrix, thus enhancing the overall repair and healing processes in the dental structure.

While substances like calcium hydroxide can also contribute to mineralization, MTA has a broader application and superior properties for stimulating mineralization, making it the more effective choice among the substances listed. Other materials, such as ferric sulfate and composite resin, do not primarily serve to promote mineralization in dental treatments in the same capacity as MTA.
