Ah, this is frustrating, and my comment is unnecessary. But I'm going to add it because I'm somewhat pedantic.
All you people who have been talking about undergrad vs post grad degrees are missing a term. Graduate.
The Bachelor of Dental Science is an Undergraduate degree. (BDSc)
A Masters of Dental Science or a Doctor of Dental Science are both Post-Graduate degrees.(MSc, DDSc at UQ)
The four year programs you gain entry into after completing a separate undergraduate are Graduate degrees. Not post-graduate. (4 yr MBBS, DDS)
A graduate degree is a degree that requires you to have completed another degree - but because that degree does not necessarily have to be in the same field, the second degree you gain entry into is not technically a post-graduate. A graduate degree still only puts you on entry level in that field. Because post-grads imply further learning and/or research in the field of your first degree.
I think the reason people are getting confused by this though is the way the universities are starting to mess with their names in order to make us think their degrees are better. e.g. Melbourne calling its graduate dental degree Doctor of dental surgery, when at UQ their highest research degree for dent is a Doctor of Dental Science. Add to that UQ have called their specialisation degree the Doctor of Clinical Dentistry, where at Melbourne it used to be a Masters of Dental Science.... of course then you have Griffith calling things Graduate diplomas and confusing everyone because it sounds worse (why oh why did they decide on that name *facepalm*)
