Thank you for the nice video. I wish i had videos like this to educate me when i was graduating. Good work.
Thank you so much Dr Ryan 🌸
Nice work Dr. Wilder!
Very clear video. Thank you doctor 🙏
Thank you so much for this catchy video!! I love it so much ❤
Thank you doctor !!!
Thank u so much..your videos are really helpful 😊😊
Thank you Dr 🌸
that was so helpful
Thanks for this! First class V tomorrow morning! D3 here!
You got this! 💪🏼💯
@mentaldental I actually just got back! Did two, 8 and 9. They were mostly on the root. They came out good! Thanks again, this was a great refresher!
Thank u soo much ⭐🙏🙏
Greaat vedio 🌟
why we do retraction cord option in the last step ? what is the reason of it ?
Doctor can you please tell us the name of the instrument you are using in the description box 🌸
3 things I do differently:
- I use a metal matrix band to retract the gingiva rather than rubberdam and metal clamp. You can angle the matrix band as you desire and then lock it in place with interproximal wedges
- I use flowable composite for maximal surface smoothness at the gingival margin. I never ever touch the equigingival or subgingival part with anything rougher than a polishing bur to prevent irregular or rough surfaces.
- I never ever blow air on the primer or bonding. This is a very common mistake that should absolutely be avoided. It is advisable to use a clean microbrush instead to soak up the excess primer and/or bonding agent. This technique gives you much better control over where the primer and bonding are and aren't going, rather than blowing it all over the place.
Other than that, nice presentation and thank you for sharing this.
Interesting approach! I never thought to use a matrix band for Class V. We're taught in dental school to blow air on the adhesive in order to evaporate the solvent, which subsequently increases bond strength.
@@jdk1313 The solvent will evaporate by itself if you give it 20-30 seconds, but on the condition that you don't use too much of the primer agent. That's why I use a second (dry) microbrush to soak up the excess primer. By doing that you solve the issue of having too much primer and you also give enough time to the solvent of the primer to evaporate
@@cvdp8665 Ah okay makes sense. Thanks for explaining!
Interesting, thanks for sharing your alternative approach. I have used the metal matrix bands for Class Vs and while I personally don't prefer them, they can certainly be useful! We will agree to disagree on point 3, as there is a wealth of data supporting the efficacy of an air-stream evaporation method rather than just wiping away excess adhesive. Do you have any high-quality evidence you can share to support this method?
@@mentaldental The method I use is largely due to personal preference, though I'm sure that your method would outperform my method in a controlled study environment. The problem I have with this method is that it is harder to reliably reproduce in practice, giving you less control over where the primer and/or bonding agent is and isn't going.
I've talked a lot about this with Bart Van Meerbeek and Marleen Peumans (KU Leuven) who both have done a lot of studies on adhesive dentistry. They both apply the same technique you use, but always taught me that you should never blow air directly at the primer and/or bonding agent, but rather use gently air flow over the cavity to fasten the evaporation process.
You must cure layer after layer not the entire paste at once
Correct! 2mm layers are ideal.
Although ideal depth for a class 5 is around 1.5mm so unless very deep Carrie’s are present there is no need for incremental curing
Why do we need to do a divergent in composite preparation? Only amalgam needs convergent and divergent
Sir i have doubt.. Sometimes patients comes with sensitive after composite restoration. Can u put a video regarding how to manage
Why are mesial distal walls divergent?
and where to place retention groove and why?
Mesial and distal walls should be more parallel, but the occlusal and gingival walls should be ever so slightly divergent to avoid having unsupported enamel rods. Retention grooves are 0.2mm inside DEJ to provide resistance to buccal displacement.
Would be nice to actually see an actual cavity being worked on
Waiting for next VIDEO..
Hey doc ... I have a question that's bit off topic but I wanted to know that once I clear my nbed and get my license do I still have to do dds or I could just practice as a dentist just after clearing my exam
For foreign students,After clearing INBDE,you have to apply for dental school for DDS,which is like 2&half year course,after that you have to appear for licence exam in particular state where you want to practice in USA,then and then you can practice there
Can I apply for INBDE after BDS from Pakistan...
And how much it cost to appear in the exam????
whats the usage of cotton rolls?
Cotton rolls help provide isolation and access to your preparation while keeping soft tissues away from harm (lips, tongue, cheek, gums).
What is the black thing you apply it first directly after using the contra ?
Can you provide the timestamp of this video that you are referring to?
Etchant
Doctor what kind of composite did you use? Is that a backable?
It is a packable composite, specifically 3M Filtek Supreme Ultra.
@@mentaldental Thank you Doctor, I am following you from Egypt and I really appreciate your efforts in this channel 🙏
😍😍😍😍🔥🤩
Why not bevel the gingival?
We never recommend beveling dentin, because the resin-dentin bond is not as predictable as the resin-enamel bond and the force of polymerization shrinkage can cause a gap for secondary caries.
@@mentaldental I'm a little confused, how is the gingival margin in dentin?
Because in the majority of cases, Class V caries or non-carious cervical defects will involve the CEJ. Even if not, by the time you make the prep that enamel layer at the gingival margin is SO thin (remember the anatomy of a tooth in cross-section) that any amount of beveling will put you into dentin.
Awesome 🌟
That is the first time that i clearly understand why we don't bevel the gingival
Thank u soo much doctor 🌟🙏

Drilling in my opinion is terrible cause I don't see how destroying the natural tooth structure and enamel is a good idea your just making that small chip bigger and covering it up, couldn't you just apply the filling? And isn't their a way to restore the enamel obviously not completely but just good enough so the tooth doesn't need to be drilled esstianly making it a healthey tooth?
Does your name end in DDS or DMD?
If not, your opinion does not matter.
