I'm a trainee, and trying to grasp this. My colleagues haven't been supportive, and have made me feel stupid when i've asked more than once, as if i'm instantly supposed to know them after being told once!
Is there a distinguishable feature of each tooth group type of forceps?? Or is it just random and dependent on brand?? Cos just when i thought i was learning a common feature of each (or example, root forceps having more elongated beaks, and no gap between the tips), i'd see a pair at my practice, or a photo in a textbook, that totally confused me again (like seeing root forceps that had quite fat beaks, and a sizable gap, and to me looked more like molar forceps). Another one that's confusing me a lot is the difference between universals, and anteriors.
What i *thought* i'd learnt, was:
Molars = have a smooth beak, and then one with a little spike/point on the opposite beak
Anteriors = have the smallest gap between tips (apart from root forceps), and are smooth beaked
Roots = smooth, elongated beak, and no gap between tips
Premolars = ??? struggle with finding a distinguishing feature to these, but i guess just a narrower, smaller version of molar forceps?
But when i'm handed a pair of "lower universals" by a senior nurse at work and going by my distinguishing features guide, they look more like root forceps (narrow elongated beak, and no gap between tips), it totally confuses me again. I mean if nothing is set in stone with each type and it's all interchangable and dependant on brand or whatever, when how am i supposed to make sense of them??
Please only reply if you want to help, i've had enough sarky comments about this already.
