Saliva provides minerals that help remineralization. Which minerals are these?

• A. Calcium and Phosphate
• B. Sodium and Potassium
• C. Magnesium and Zinc
• D. Fluoride and Chloride

Answer: (A)

Remineralization of enamel depends on mineral ions in saliva that can redeposit into demineralized areas. The minerals saliva provides for this process are calcium and phosphate, which combine to reform hydroxyapatite in the tooth structure. Their presence creates a reservoir that supports repair after acid attack, helping restore mineral content. Fluoride can enhance remineralization by forming fluorapatite, but the actual minerals supplied by saliva for remineralization are calcium and phosphate. Other ions like sodium, potassium, magnesium, zinc, and chloride are not the primary contributors to enamel remineralization.
