find

I need files ending with ".pdf" or ".png"; here's my attempt:

find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*[pdf|png]'

this incorrectly includes files ending with "Apdf", "Zpdf", etc. (missing literal dot before file extension)

I tried adjusting the pattern to:

find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*\.[pdf|png]'

but then no results are returned. Escaping the . with a backslash does not work. Why?
