What is an advantage of using zinc polycarboxylate over zinc phosphate?

• A. It is more acidic than phosphate
• B. It is less acidic than phosphate
• C. It is more brittle than zinc phosphate
• D. It is more expensive than zinc phosphate

Answer: (B)

Zinc polycarboxylate's lower acidity compared to zinc phosphate is a significant advantage in dental applications. The less acidic nature of zinc polycarboxylate makes it less irritating to the pulp and surrounding tissues, promoting a better response during dental procedures. This characteristic makes zinc polycarboxylate more biocompatible and suitable for use in various situations, including as a base or liner under restorations. Furthermore, its ability to bond chemically to tooth structure is enhanced due to the pH level, maintaining the integrity of the tooth while providing adequate support and protection. This not only supports better dental health outcomes but also makes zinc polycarboxylate an effective choice for procedures requiring a more compatible material with dental tissues.
