Cannes 2007 Shortlist
While curiosity is one thing, giving people a reason to scroll a banner will always work better. Also I'm guessing AACD is different in Brazil as Google tells me it's the American Academy of Cosmetic Dentistry. I'm guessing this banner would have been to generate donations? A call to action at the end might have helped.
Note: Normally I wouldn't be so critical but for something shortlisted at such a well renowned award show you expect to see best of practice coupled with great ideas and execution.
