Which type of cement is known to inhibit recurrent decay?

Glass ionomer cement is known for its ability to inhibit recurrent decay due to its unique properties. It releases fluoride over time, which can help remineralize tooth structure and provide a protective effect against caries. This fluoride release creates a hostile environment for acidogenic bacteria, thereby reducing the risk of recurrent decay.

Additionally, glass ionomer cement has good adhesion properties to tooth structure and can effectively seal the margins of restorations, further minimizing the potential for decay at those margins. It's particularly beneficial in areas where moisture control is challenging, such as in pediatric dentistry or in patients who have difficulties maintaining oral hygiene.

While composite resin and resin-modified glass ionomer also provide good sealing capabilities and some level of fluoride release, glass ionomer’s broader and more sustained fluoride release makes it particularly effective in preventing recurrent decay. Zinc oxide eugenol, while useful for certain applications, does not have the same fluoride-releasing properties and is typically used for its sedative effect on the pulp rather than for long-term prevention of caries.
