PVS is an example of an ____.

addition silicone
condensation silicone
polysulfide
polyether

The correct answer is: addition silicone

PVS is an abbreviation for Polyvinyl siloxane, which is a type of addition silicone. Addition silicone is different from condensation silicone, polysulfide, and polyether because it is a type of silicone that carries the vinyl group and undergoes an addition reaction to form a crosslinked network. Condensation silicone, on the other hand, undergoes a condensation reaction and releases water as a byproduct. Polysulfide is another type of rubbery material used in dentistry, but it is not a silicone. Polyether is also a type of rubber material, but it has a longer setting time and less hydrophilic properties compared to addition silicone. Therefore, PVS is an example of an addition silicone and not the other options provided.
