apparantly you are not a dental student...otherwise you would know that the main reason dental schools require students to collect teeth are for restorative and endo practice...not to study morphology. 😉
to the incoming students who wonder if they should collect teeth...YES! ask your local dentist / whomever you shadow, and collect as many as possible. you will need bombed-out teeth to practice large / complex restorations, and u will need teeth for endo class. be wary of upperclassmen!! they will ask to see your collection of teeth, and jack you of all u'r good endo teeth. you will need them to learn, need them for projects, and ultimately, you will need them for boards. so hang on to them. BUT if you happen to get luck and have a lot, then be nice and share (some board candidates are even willing to pay $50 / tooth for teeth that straight canals!) to store them, you can keep them in a jar with chlorohexadine....that works the best and doesn't stain the teeth. if you can't get that, you can use the yellow listerine (don't use and blue or green mouthwashes...they will stain your teeth).
so to make a long story short...YES, you do need to collect teeth.... 😎
