Fluoride-releasing restorative materials help to prevent what kind of dental caries?

  1. Recurrent caries

  2. Primary caries

  3. Secondary caries

  4. Incipient caries

The correct answer is: Recurrent caries

Fluoride-releasing restorative materials help to prevent recurrent caries, which are cavities that form around existing dental restorations. This type of caries is commonly caused by bacteria and plaque buildup around a tooth filling, crown, or other dental restoration. Options B, C, and D, correspond to different types of primary, secondary, and incipient caries, respectively, which are not as directly affected by the use of fluoride-releasing restorative materials.
