Dental Materials
Silane-coupling agents are used to improve the bonding between filler particles and the matrix in dental composite materials. They contain a methacrylic group that can co-polymerize with the dimethacrylate monomers present in the matrix, while also having functional groups that can interact with the filler material, typically silica or glass particles. This dual interaction creates a chemical bond, which enhances the overall stability and strength of the composite material.

The patient's presentation of a puffy face (facial edema) and swollen ankles (peripheral edema), along with markedly raised protein levels in the urine (proteinuria), are classic symptoms of nephrotic syndrome. This condition occurs when the kidney's filtering units (glomeruli) are damaged, allowing excessive protein to leak from the blood into the urine, which in turn causes fluid retention and swelling in the body.

Dental Materials
A base material in dental restoration is primarily used to provide a seal against microleakage.
