Hey! I'm just curious how often students make crucial mistakes during a procedure, such as drilling too deep and turning a filling into a root canal, or something worse...

							In a year of clinic, just once. All I'll say is: Rely-X probably isn't a good cement to use when it's your first time cementing a cast post.

 3M after spending likely a few million in advertising reassured a bunch of dentists and continues to sell millions of dollars of Rely-X every year.  While I don't have any factual numbers, it wouldn't suprise me 1 bit to see that Relx cement is IN more dental offices where units of crown and bridge are cemented than it isn't in - it's that popular and has that good a track record!  And after 15+ years of cementing units of crown and bridge, the vast majority of the time, if your patient has good hygiene, if there's an issue with a cement in the very short term post cementation, the problem more often than not is due to dentist error (improper mixing technique/moisture control or prep design error) than it is an actual problem with the cement

Too slow, didn't seat the post fully in timeWhy?? To slow on your part from mixing to seating?? Or not enough retention?? And if it was not enough retention, did you have enough post length or ferrule??

Been there, done that!
And I'll bet that you'll never have that happen again having realized what a pain it is when that occurs. For the rest of your career, either you (or your assistant) will be quick with the spatula and mixing pad and getting that freshly loaded new crown or cast post fully seated well within the working time of the cement! Plus, this is one of the main reasons why I keep a small timer in my operatories. There is no guessing then about how much time you have left to work with a cement or has the full set time been reached on a cement or impression material or temporary material, etc
Yup. BIG difference between setting time and working time, which I painfully learned the first time I tried to cement a crown. 😳
