This one should be used by Pedodontics all over the world i
think, this image really makes me remember my posting in Pedo Dept where
i came across a really naughty child who was not at all co-operative
and the Doctors and his parents in the clinic had a hard time getting
the boy to cooperate.
I think this kinda setup will surely fix the problems.

I think this a good dental joke to have a good laugh at
