[2025-10-02T01:17:41.107051] [PI reasoning] **Analyzing GIC adhesion mechanism**

I’m looking at the question regarding the adhesion mechanism of glass ionomer cement (GIC) to tooth surfaces. It looks like it bonds through ionic interaction, specifically chelation of calcium ions by carboxylate groups in polyacrylic acid. Among the options, "B. Chelates with Metal Ions" seems the most accurate. While option A refers to the carboxyl group as a functional one, option B covers the overall mechanism. I need evidence from literature, so I’ll search for information on GIC adhesion and chelation with calcium.
