Thanks for the video. Im a current d3 dental student at ucla. I noticed that your axial wall is concave. My faculty has always really pushed for the axial wall to be convex like the natural tooth structure. I was wondering what your opinion is on this? Again i appreciate the videos. Its nice to see the touch that somebody else has up close.
@StevensonDentalSolutions4 жыл бұрын
This is a caries removal tooth, not an ideal tooth. For ideal preps, the axial wall must follow the outer gingival margin.

@StevensonDentalSolutions8 ай бұрын
ADEX allows for up to 1 mm of clearance for an ACCEPTABLE SCORE. Over 1.0 mm but less than 2.5 mm of clearance would Grade SUB (Marginally Substandard). I would shoot for 0.75 mm and then ask for a modification if you must extend further.

hey, needing advice! I am retaking and had the 29 DO and I did not leave any caries but I over-prepared my procimal wall, axial, and isthmus. i was confused because i thought they wanted us to go to the max of each of these dimensions ie near 1 mm proximal clearance, 1 mm from the DEJ etc. but also, there was mesial occlusal caries that you could not find unless you went 2mm deep and some people faield because of left caries in that area. is it typical to have the caries not connected for this exam? any adivce on going to the max i would appreciate!
@StevensonDentalSolutions4 ай бұрын
I would prep to ideal then only extend those walls required to move due to caries, slightly less than the ADEX max allowed, then involve the FE for permission to extend. If you prep 1.5 mm pulpally, you can see the decay. Stick to a traditional style prep, and not a slot or box.

I noticed you left your axial wall concave what is your opinion on those who teach that the axial wall must be convex?
@StevensonDentalSolutions Жыл бұрын
in an ideal prep with no caries, convex axial walls is appropriate. When removing caries, the axial wall will become concave, due to a caries focused modification. Creating a convex axial wall after caries removal is contra-indicated as it removes perfectly health tooth structure for no apparent benefit. Placing a liner and base in order to build the wall back to convexity may seem appealing but the "minimum basing concept" has clearly shown that this practice affords no advantage, except perhaps pulpal protection...however, with typical D1 caries, (out 1/3 of dentin) placing a base is not considered necessary.

The conventional outline as shown will always be accepted. There is no way for the plastic tooth to having carious fissures anyway. Alternatively, you may certainly prep a slot with grooves and spare the occlusal. It's up to you.

@StevensonDentalSolutions2 жыл бұрын
The RTX teeth are made specifically for WREB Exam practice, while the DTX teeth are made exclusively for ADEX Exam practice. The artificial caries in the RTX teeth behaves differently than the DTX teeth. Caries in the DTX teeth penetrates the DEJ in a more realistic manner. Having said all of this, neither type are actually used on the exams. The WREB and ADEX use special exam teeth which are similar but not the same...
