I don't know why you wouldn't bevel any composite prep if you're on enamel. Unless you're doing a class IV amalgam I guess.

They don't have us bevel class IIIs.

They should. It helps blend shade discrepancies; it cuts & exposes enamel rod endings, which bond much more strongly than their axial surfaces; and it increases bonding surface area.

Hey I know all that stuff haha but they mentioned that we don't need to do it. So far we've only prepped from the lingual so I'm guessing that the shade discrepancies wouldn't matter for that. I agree with exposing more enamel rods but they still don't make us do it. We do it for class IV and class V.

just because your clinical instructors dont have enough faith in your hand skills to place a nice shallow angled bevel doesnt mean you shouldnt be learning to do so. it really makes for greater marginal integrity and increased bond longevity. (that is, not just the initial strength, but strength of the bond over time).

inexperience is the only reason i can come up with for telling students not to bevel lingually accessed class IIIs, especially if they have you doing so on IVs and Vs. did they give any other rational?

I honestly do not remember which is probably a bad thing. But they definitely mentioned that it was not necessary when I showed them my prep.

BTW, they make us do everything to perfection, as a d-school should. I find it odd that they would randomly have us cutting corners or missing an important step. Our operative instructor can be quite anal about making a correct prep.

Wouldn't placing a lingual bevel on a maxillary class III potentially create an issue whereby occluding on said bevel may cause material fracture?
