What restoration material is preferred for root caries?

Explanation:
Root caries challenges the restoration at exposed root dentin where moisture control is difficult, margins may be at the cementum-dentin junction, and fluoride exposure can help slow progression. Resin-modified glass ionomer is favored because it chemically bonds to dentin, releases fluoride to help remineralize and inhibit recurrent caries, and tolerates moisture during placement better than many other materials. This combination promotes a good seal at the root surface and reduces the risk of leakage and secondary caries. In contrast, composite resin, while esthetic, is more technique-sensitive in a moist root environment and prone to polymerization shrinkage that can create gaps; amalgam lacks fluoride release and is less desirable esthetically and for root surfaces; ceramic isn’t well suited for root caries due to brittleness and the need for precise bonding.
