"I found the practice tests extremely helpful. I passed the DANB RHS exam and felt that the subject matter was thoroughly covered by your practice tests. The viewing of films and answering questions on them was especially helpful. Thank you very much for the assistance in preparing for the DANB RHS exam."

DANB NJ Expanded Duties General Exam - Test Reviews Sample Questions

Which of the following is the CORRECT components of a composite resin material? 

Correct Answer:
organic resin matrix, inorganic filler, coupling agent
the correct components of a composite resin material are: 1. **organic resin matrix** 2. **inorganic filler** 3. **coupling agent**

each of these components plays a crucial role in the properties and functionality of the composite resin, which is commonly used in dental restorations like fillings and crowns.

**organic resin matrix:** this is typically composed of a type of synthetic resin, most commonly bisphenol a-glycidyl methacrylate (bis-gma), urethane dimethacrylate (udma), or triethylene glycol dimethacrylate (tegdma). the resin matrix forms the bulk of the composite material, providing a binding medium for the inorganic fillers. it is responsible for the overall handling properties and the aesthetic appearance of the composite resin. the matrix also reacts during the curing process to solidify the composite, linking chemically through a process known as polymerization.

**inorganic filler:** these are made from glass, ceramic, or silica particles and are added to the organic matrix to improve the mechanical properties of the composite, such as strength, wear resistance, and thermal expansion coefficient. the fillers also help in reducing the shrinkage of the resin upon curing and improve the tactile and aesthetic qualities of the finished product.

**coupling agent:** typically, this is a silane compound that acts as a mediator to bond the inorganic filler particles to the organic matrix. the coupling agent provides a strong bond that ensures the effectiveness and durability of the composite resin. without an effective coupling agent, the filler particles could detach from the matrix, leading to weaker mechanical properties and potentially shorter lifespan of the restoration.

in summary, composite resin materials are carefully formulated to provide optimal performance characteristics for dental restorations. the combination of an organic resin matrix, inorganic fillers, and a coupling agent allows for a durable, aesthetically pleasing, and functional material that aligns well with the natural properties of tooth structures.
