Which type of glass ionomer is specifically known for its fluoride release?

The type of glass ionomer specifically known for its fluoride release is Type 3. Glass ionomers are dental materials that bond to both enamel and dentin, and their fluoride-releasing properties are one of their key advantages, particularly in preventive and restorative dentistry.

Type 3 glass ionomer cement is designed for use in specific areas such as temporary restorations, where the release of fluoride is particularly beneficial for protecting the tooth from decay. The characteristic of releasing fluoride helps in providing a reparative effect on the surrounding dental tissues by promoting remineralization.

In contrast, Type 1 is typically used for luting cement, and while it does have fluoride-releasing properties, it is not primarily recognized for this feature. Types 5 and 6 are specialized materials with uses in different contexts and do not emphasize fluoride release as their main attribute.

This makes Type 3 the most representative answer in the context of fluoride release among glass ionomer types.
