Which of the following is NOT a component of resins?

• A. BisGMA
• B. Filler particles
• C. Water
• D. Photoinitiator

Answer: (C)

Resins, particularly those used in dental applications, are typically composed of a variety of components, each serving a specific function. BisGMA (Bisphenol A Glycidyl Methacrylate) is a common monomer used to create the polymer backbone in many resins. Filler particles are added to resins to enhance their mechanical properties and to improve the overall strength and wear resistance of the material. Photoinitiators are crucial for the curing process; they are substances that initiate the polymerization reaction when exposed to light. Water, however, is not a standard component in the formulation of these resins. While some materials may incorporate water in different contexts, such as in aqueous solutions or for storage purposes, it is not a fundamental part of resin composition. The absence of water in the formulation helps maintain the integrity and performance characteristics of the resin during application and curing. Thus, identifying water as a non-component aligns with the typical understanding of resin chemistry in dental and material sciences.
