Paraphilia Phriday 6

I had to make this name up. That's a good thing, because I'm hoping this is a very isolated paraphilia. It's a very specific manifestation of a much broader paraphilia, sadism.

Dentist comes up with his own concoction; a special cleaning solution/hemostatic.

So why does this max out my disgust-o-meter whereas it wouldn't if he'd "merely" raped those women?
