Radiographically lesion looks smaller because demineralisation is less than 50% and hence full extent of carious lesion can't be detected
Great. You are right
Sir you're just awesome. You made composite so much easy for me. Thank you so much sir.
Greatful for the appreciation. If you like my videos , help me teach more students by sharing this videos on whatsapp and other special platforms :)

This was amazing lecture 🥰
Thank you :)
Thank you sir .....these videos are not just about very well informed videos but also so inspiring to teach in such a super clear way.
You are most welcome. I understand how difficult the topics are difficult to grasp in initial days of learning. Glad to hear to those beautiful words of appreciation :). Do share the links with you friends. Lets learn it together :)
Thank you sir..it was very informative and got many things clear about class 2 cavity preparation.❤
Thank you Anikta. I am happy that you liked the video a lot. :). Do share it with your friends if possible. I want others to understand the concepts easily :)
Thanks a lot sir. Bull's eye explanation and clinically oriented. Looking forward for new videos. Can you take 'how to locate canal orifices' as a topic?
Hi Prasand. Thank you for the feedback. Also I do agree that we can make a video on how to locate the canal.. However for that I need to make clinical videos which I would surely work on, but post covid :)
Meanwhile also check-out our other videos :)
@@Aspire32 Sure sir
Really super sir thank you ☺️

Thank you very good covered
Thank you :)
Thankyou sir 😍🤗🤗🤗
Welcome Kiran :).. Your smilies indicate that the video was helpful :)
Amazing!!!
Thanks!!
Radiographic lesions appear smaller because 40-50% decalcification is required to be evident on intraoral imaging
Thank you for replying :) Appreciate it :)
Great answer. :) Expected.. You are supper intelligent :)
very informative thanks alot
Most welcome n:)
Sir amazing video and sir it's a request to make a video on what special consideration do we have to kept in our mind while using composite and gic as a restorative material in class 2 cavity prepration
I am currently working on cement series. Today released zin phosphate. Do check it.
Did you check my Composite video ?.. it covers the basic. Will consider to make a clinical video
@@Aspire32 sir i do check ur every video i have seen the composite videos actually every video is superb but i just want to know is there any thing special that we do prepare class 2 cavity when we have chossen gic and composite as a restorative material
Got it. I will try to make one about this. Soon:)
Bravoo sir bravooo
Hi sir
What is the shape of proximal box ?
Thank u so much sir❤❤
Most welcome :)
Thank you so much for these videos. I have been watching them all day. I just want to clarify a few things if you have time please; we bevel the axiopulpal line angle always regardless of composite or amalgam, correct? And we never bevel the cavosurface margin on amalgam, but we do on composite right?
For amalgam we bevel in gingival cavosurface margin in class 2. For composite we bevel everywhere except the occlusal area
Pls watch this video to understand it better
ua-cam.com/video/oRfTlb3uM3Q/v-deo.html
Yes.we rounden axiopulpal line angle
Hello sir very well explained.u asked the que.. radiographic lesion is less than the clinical bcz it requires 30 percent destruction to appear radiographically..
Right answers :). Thanks for watching. Do check other videos and subscribe :)
@@Aspire32 thank you sir.regularly watching ur videos for afk exam and already subscribed
Thank you :) hope to make many more videos :)
Nicely explained sir
Thank you Harsh :). I hope you will Subscribe to the channel. Do check the other videos. Evey video will help you to understand the topic Better :)
Thank you sir 😊

Omg thank you 😭😭
Welcome. Looks like you are happy with the video :)
Very good video.
Thank you very much!
sir may i ask to clarify this more ( if more of the explorer is passing beyond the contact this means the proximal wall is more than what is required ) do you mean that the explorer tip should only pass through the contact, and if is more than the tip is passed this means more than required ?
Yes. If the caries was small and u made a preparation in which the more instrument is passing between the walls then this means the box is widened more than needed
Thank you Sir
Most welcome n:)

Sir can you please comfirm that buccolingual dimension of gingival seat should be 0.2 to 0.3mm as you told that it would be same as for proximal box ?😊
I did not get you
How do you prevent the fracture or dislodgement of composite class 2 restoration?
Dear Sir, There are many reasons for dislodgement of composite,, The most common being improper isolation. Also its important to select the correct bonding agent for the tooth structure. I hope you will see our popular video on Dentin bonding agent which can help you with the selection of proper generation of composite. For the fracture, most of the time its because the time its in high stress bearing area like involving Class 2 involving more cuspal area for which composite may not be a ideal material.
Sir please make videos on commonly ask Viva questions in preclinic conservative
I do mention the questions in each video. Hope you will check all videos
Hello sir, my question is patient with class 2 lesion on mesial surface of mandibular molar that extends onto contact point but occlusual surface is intact then which conservative technique we will follow to reach this lesion and how will restore this tooth??
Pls check this video
ua-cam.com/video/oRfTlb3uM3Q/v-deo.html
The best method is still box only because other techniques may be difficult to prepared
Thanku sir
Most welcome :)
Sir it was amazing to attend your lecture thankyou very much for your efforts
And i have one doubt why do we need to break contact and give clearance?
Breaking contact get the margin in self cleansable area. I think I must have explained it in fundamentals video. Do Check here

Thankyou sir

Sir is it possible to make videos on injection moulding technique and rubber dam..
Hi:). Thank you for commenting in the video.. injection moulding technique is bit difficult. I can make a video on rubber dam. But I usually cover theory aspects.. do u want theory ?
It would be great sir.... Your concept explainations are crystal clear... A fabulous teacher...
Dr Iam new on the your channel, i like your videos . I want Ask about how to know the measurment , for exempel when i stoppning 0,8mm from marginal Ridge and the start With proximal box , how i can know that is 0,8 mm?
1 mm is easy to look. Eventually once u keep doing it , it will come with experience and you dont to think too much about.mesurements
Sir,is it necessary to prepare occulasal surface if caries is not extended till the occlusal area?if yes why we sacrifice sound occlusal area ?and is it also necessary in composite restoration to formation of bevel and unexposed occulusal area???
It depends on how wide is the proximal box and how much enamel is left for bonding. If the box is too wide, one can extend it on occusal area to increase retention of composite restoration.
For occusal area but joint is preferred for composites. For rest all area bevel can be given to increase bonding.
@@Aspire32 thanks a lot sir. I m a beginner and and ur channel helps me a lot.sir can we use shofu composite in class 2caries?is it good or we use some other brand?
@@Nehakumari-in9wh most welcome:) any brand is fine :)
To be evident on the radiographs, 50 % or more demineralisation is necessary, so extent is more in clinical condition than that on radiograph...
Thanks great. 30 to 40%
👏👏
Sir what to do if the carries reaches beyond the cej? And what restoration we have to give ?
There are many options. Best would be do Crown lengthening and get a better margin.
Cast Restoration are also better for subgingival restoration
Are Restorations can be used for root carries?
You can. But if the lesion is below the level of gingiva then it can irritate the tissue. Also if you are doing Composites restoration then Composite wont cure in thag area.
Thats why its better to use cast Restoration if the lesion is below gingival level.
Or else you can reduce the height if gingiva so that more tooth structure is exposed, as done in crown lengthening
@@Aspire32 thank you so much sir.. I've seen many dentists advise extraction for root carries so I asked for clarification...thank you sir
Hey dr amazing lecture.. But how is 0.6 is 2/3 0.8? And 1/3 is 0.2 arent we supposed to divide 0.8 by 3?
2/3RD of 0.8 mm is is 0.53
the additional 0.07 may be the thickness of DEJ since we are measuring from that point
Useful qn
Sir is it necessary to varnish Matrix band in composite filling?? without varnish do composite stick to matrix band??
We dont apply varnish to matrix for composites not amalgam
Sir, the radiographic lesions looks smaller because of the angulation of xray tube.
Thank you for participating.. I will post the answer in your reply in 3 days :)
Things will appear on radiograph only where there is 30 to 40 mineral losss. So clinically thr caries has progressed but the mineral loss may not be sufficient. Hence it wont be seen in xray as much as clinical size
Thank you sir:)
Sir , please do make a video on "Finishing and Polishing". Please sir 🙏🏻🙏🏻
Surely :).. Hope you will check other videos and subscribe to the channel :)

Is there any video for class 1 cavity?
Not yet. But fundamentals of tooth preparation can help
Hello sir. In steps of cavity preparation you said we have to enter from uninvolved side but in art and science it says we have to enter the pit which is nearest to the involved proximal surface, aren't these two different things? Please correct me if i am wrong
You should start from the involved side.. as per the book.
Oh so then it is involved side. Thank you 😊
Yes. That allows u to make a conservative prepration if the other area is not affected.
Thank you sooo much sir 🙏 i got it now
Most welcome :)
can someone reply to the question sir posted at end of video?
Its there in one of the comment
I have a question... What are internal and external walls in class 2 prepration?
Its given in surrdavent
Sir i hve a doubt ki radiograpically those cones r seen ?? Usually ??
They do match the shape. May not exactly match
@@Aspire32 okay sir
From which book is your lecture, Sir?
Sturdevant
Answer:: When there is 30-40% mineral loss only than it is visible radiographically. That’s why it appears small. Thank u doc
Great :)
Sir What is the importance of clearance
Great question. I will soon make a video :)
𝙏𝙝𝙖𝙣𝙠𝙪 𝙨𝙞𝙧🙏🙏🙏
Most welcome :)
Sir what is bevel
Bevel is explained in this video
ua-cam.com/video/DqMaCXL7qpI/v-deo.html
Because radiograph only shows demineralised area/ infected dentin not affected.
Yes. 30 to 40 deminralisatiin is must if u need to see it on xray
I'm still not clear about bevel regarding enamel rods.
Pls check my inlay video. I have explained bevel in that
Sir how much marginal ridge should be left means value is different in clas 1 and 2
1.6 for premolar, 2 mm for molar
