What is Restin used for?

Arestin is an antibiotic in powder form that can easily be placed into pockets. It contains "Microspheres" (tiny, bead-like particles that are smaller than grains of sand). These microspheres are filled with an antibiotic called minocycline, and they release the drug slowly into the infected periodontal pocket, killing bacteria that live there for up to 21 days. Arestin also reduces the size of periodontal pockets, killed the bacteria associated with periodontal disease, and reduced BOP of the gums.

My question to you is "Why should this hygienist have used arestin if there was no infection?"
