Pictures or movies of simulated models of teeth just doesn't cut it when you have to integrate new methods into a busy practice. Movies are fine for a sales pitch at a convention booth but not if you expect to put those skills to work for you. Dentistry and especially endo, requires psycho-motor skills. You need hands-on experience to develop those skills. There are never more than 16 dentists per class.
Individual attention is the norm.
And you need bring nothing with you except a desire to learn. Ask any one of the 22,000 previous attendees. There will probably be several in your class. About 50 per cent of each class is retakes. You may not have heard of 'Automated Endo' because until recently we didn't even send letters to new graduates.
