Which restorative material is particularly well suited for root-surface (cervical) caries in older adults due to fluoride release and chemical bonding?

Glass ionomer chemically bonds to tooth structure and releases fluoride, making it ideal for root caries, areas of moisture control difficulty, and high-caries-risk patients.Other options: Amalgam, porcelain, and gold do not release fluoride or bond chemically to dentin like glass ionomer.Key exam takeaway: Root/cervical caries: glass ionomer (fluoride release + chemical bonding).
