You know, I found the first day harder, and the second day not so bad with the cases. But some of the pictures seemed weird. SOme cases said the tooth had caries, but there were no radiographic evidence nor were there any clinical evidence of caries. So how would you treatement that? DId you take their word for it, is it a trick or should you answer based on what you see on the boooklet. Anyways, I check the mail everyday single day, and each time my heart beats a million times over, and yet, there's nothing.
