some question about modification of class II

after the ideal preparation was completed, if there is some caries left in

pulpal wall or axial wall, do we need extend the whole pulpal wall (to pulpal

direction) or axial wall (to axial direction) to remove caires? or just remove

the caries (not extent the whole wall)?


if there is some caries left in gingival floor (in proximal box) or buccal

proxiaml wall, do we need extend the whole gingival floor (to gingival

direction) or buccal proximal wall (to buccal drection)? or just remove the

caires in gingival floor or buccal proximal wall (not extend the whole wall)?


thank you so much!
 
You don't have to extend the whole wall unless its a buccal or lingual wall. You just remove the decay with a slow speed round burr.
 
For all your examples, you just go where the caries is. You don't have to extend the entire axial wall, lower the pulpal floor or proximal walls. You basically just put in your round bur and get the caries out. However, for the proximal walls, you might have to extend the whole thing so it's not undermined. Ask for mods. I think it's actually good because it looks bigger and the examiners will not know how far from ideal it is. What I mean is that you have more wiggle room and you can make a bigger prep. If the examiners feel like the mods are obvious, they'll just sign off and you don't have to bring the patient back. If it's questionable, you have to send it back to have the examiners decide. Good luck with WREB exam.

I have a question?
When you have to ask for conversion of MO or DO into MOD. I mean when how much marginal ridge left after during removal of caries. (0.5 or 1 mm etc.)

1mm is a good guage. Anything less is pretty thin and you should request the mod. Also, if the transverse ridge is less than 1, you should also extend occlusally, for like the man. premolar or max 1st molar. If you see the initial x-ray is incipient, you could also request to do an MOD. One of the proximals have to be qualifying though. Ex, if mesial breaks the DEJ and the distal is borderline, you could request to do an MOD prep when you send it back for acceptance.
