What is the primary mechanism through which glass ionomer cement (GIC) adheres to the tooth surface?

Show Answers

Interaction via carboxyl groupsFormation of chelates with metal ionsBonding through carbon-carbon double bondsAdhesion by polymer chain entanglementMechanical interlocking

Explanation

The adhesion of glass ionomer cement to the tooth structure occurs mainly through the carboxyl groups in the cement, which chemically bond to the calcium ions in the tooth. Other mechanisms like chelation, polymer chain interaction, or mechanical interlocking are not the primary means of adhesion for GIC.
