I would recommend Nytril gloves over vinyl. My daugther-in-law works in a dentist office and developed a vinyl allergy. The problem is it not just vinyl - its becomes anything rubber. Pens, streering wheels, gear shift knobs, camera bodies & lenes, etc. She continuily has to fight it down (BTW, she had to change jobs because of it). In her case the allergy seems to be what ever chemicals they use to process or vulcanize the rubber.

I changed to nytril because of it.
