What advantage does composite have over silicate resin?

• A. Less shrinkage
• B. Less surface erosion
• C. Less water absorption
• D. All of the above

Answer: (D)

Composite materials indeed have several advantages over silicate resin, making them a preferred choice in many dental applications. One of the key benefits is less shrinkage during the curing process. This reduced shrinkage leads to improved marginal integrity and decreases the risk of voids or gaps that can result in secondary caries.

In addition, composites typically demonstrate less surface erosion compared to silicate resins. This enhanced durability contributes to a longer-lasting restoration, maintaining aesthetic appearance and overall functionality. Moreover, composites have a lower tendency for water absorption. This characteristic is crucial since it limits dimensional changes and degradation over time, particularly in moist environments typical in the oral cavity.

Therefore, the correct answer encapsulates all these advantages, highlighting the overall superiority of composites in various aspects when compared to silicate resin.
