This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Dental
The integration of the fluoride-releasing capability of glass ionomers with the durability of resin composites is seen in: 
Select and explain. 
A. Cermet, B. Compomer, C. Hybrid ionomer, D. All of the above
B: Compomer
Answer: B: Compomer 
Explanation: Compomer is a polyacid-modiﬁed composite made by incorporating glass particles of GIC in water-free polyacid liquid monomer with appropriate initiator. 
The rationale for using this material is the integration of the ﬂuoride-releasing capability of glass ionomers with the durability of resin composites. 
Compomers possess properties distinctly diﬀerent from those of resin composites and glass ionomers.
