Quick correction! At 7:06 I meant to say the mesial root usually has 2 canals (not the distal canal). The diagram shows this correctly. Thanks for watching!
Hi Dr Ryan, I have a question, here in Vedio you said all premolars has 2 canals, but in Bootcamp it says all premolars as 1 canal except max first Premoalr with 2 canals, I am so confused which one to learn. Please reply Thanks
@@doc-bu8ek Nope! If you go back and listen carefully, I said that "upper and lower premolars can certainly have two canals," but that doesn't mean they always do. For every premolar EXCEPT for the maxillary first premolar, having 2 canals is more common than having 1 canal. However, every premolar in the mouth is capable of having 2 canals. For more information, check out my Dental Anatomy series!
I’m a dentist with one year experience now but I’ve been following you since I was a student. I just want to say a BIG THANK YOU for these videos, I’ve learned so much about dentistry only from watching your videos ❤
I made a song " white - Yellow - red - blue - green - black" !!! hahahahaaha!!! Thank you Dr.Rian for all that content! You help me a lot! God bless you!
Great job! So informative. I've been in the GD field for 9 years, but just recently started working for an Endodontist.. I cannot believe how incredibly detailed it gets! Its super interesting.
Thank you so much for this. I'm a student dental nurse. This really helps me to understand what is going on, and support the dentist more effectively. X
Thanks so much for your videos! They are amazing! One thing I did notice in this video though is at 7:06 when talking about the canals of the mandibular molars, you say the distal root usually has 2 canals, but the diagram correctly shows the two canals in the mesial root.
Great video! EDIT: the rest of this comment is poppycock. Ignore it. One correction: The formula to find the diameter of a file at a given point should be: File size + Taper*(Dx-D1) So a size 15 would be: 0.15 + 0.02*(16-1) = 0.45 If we just multiply the 16 by 0.02, we're neglecting the fact that we label the tip as D1, rather than D0. In other words, starting at D1, we increase by 0.02mm 15 times to get to D16. That means .30mm on top of the starting 0.15mm. I though really hard about this, but feel free to correct me. I'll delete this if you convince me I'm wrong lol.
Ah, this is a real head scratcher! I think the problem is getting caught up in the nomenclature of D1 vs. D16 and what they represent. By your logic, if we wanted to figure out the diameter of a file 1mm from the tip, the result would be 0.15 + 0.02(1-1) which would give 0.15 which is not correct because we know it should be wider than at the tip. The way you calculated it would tell you the diameter 15mm from the tip, not 16mm which is how long the cutting flutes of a traditional file go until. Does that make sense?
@@mentaldental I think you hit the nail on the head when you said the problem is in the nomenclature. So many diagrams point to the tip when they say D1, rather than just saying D0. For example: bit.ly/2DsKlqq vs bit.ly/39RfyQ6 Classic dentistry. Additionally, I feel like I remember learning it the way I explained. BUT, what you're saying is pretty undeniable lol. So I agree with you! Thanks for the response.
Dear Dr. Ryan, The access opening for a mandibular molar is trapezoidal in shape A- To establish straight-line access B- Due to the shape of the crown C- To include any remnants of pulp horns within the access opening D- To facilitate the final restoration of the access opening (you have mentioned both A and D in the first slide, which would be the best response)? Thank you so much!
At 7.09 did you mean mesial root of the lower molar that has 2 canal? Im having Thai board exam next week! Your video helps me a lot thanks for greats video!
Step Back Technique involves preparation of the apical third initially ...The one which you have mentioned is Hybrid Technique.. (some books say this ) which one is correct Dr.Ryan ??
I don't understand why you mention that the diameter at the tip is D1 instead of D0. All file manufacturers identify the tip diameter as D0. D1 should be 1mm from the tip and in the case of a 15 file with a .02 taper, the diameter would be 0,17mm. Please expand?
@@mentaldental i just wanted to ask about this, and i noticed that somebody already asked, so in distal root there is more often 1 canal :D thx for these very informative videos and keep up
Hello, I wanted to ask something. I need to have root canal treatment at the dentist, but I have never had local anesthesia before. My doctor told me that I should do an allergy test and gave me the medicine he used (ultracain) how is the allergy test done for this drug?
Hello Dr Ryan I am a final year dentistry student and actually had a question in regards to the ZOE sealer used. In the Europe ( Prague, CZ to be specific) they teach us to use neo-MTA (preferred but more expensive) or resin sealers (esp Epoxy resin type) and they told us ZOE lasts only for a few years. Here ZOE is recommended for temporary teeth only (used without GP) I wanted to ask why ZOE is preferred in the USA and clinically does it actually last for a few years only? Looking forward to hear from you
dr ryan thank you for the amazing videos. one question, doesn't file size 15 for example mean that the diameter is 0.15mm, at a 1mm distance from the tip? rather than at the tip please?

One correction:
The formula to find the diameter of a file at a given point should be:
File size + Taper*(Dx-D1)
So a size 15 would be:
0.15 + 0.02*(16-1) = 0.45

13:03 the tip should be D0 or else .02 would not be times 16mm at D16, please correct me if i am wrong

@mentaldental same question here........ can you please clarify Dr ?
Or is it just a small mistake?
God bless u doc thank u so much
Thank you! God bless you 😀
Thankkkkksssss !!!!!💜💜💜💜
Thank you Dr.Ryan ,12:00 but what I know that D0 represents the diameter at the tip ,and D1 is 0.17 in this example .. Are they different systems ?
Yes, there are different methods of labeling those two points, and the one you mention is an alternative system.
@@mentaldental Wouldn't D16 be 0.45mm if we labeled the tip as D1=0.15?
The math makes sense if D0=0.15mm, then D16 would be 0.47mm
Love your videos!
On 7:07, do you mean mesial root?
Yes I did mean mesial root. Thank you for the correction!
@@mentaldental i just wanted to ask about this, and i noticed that somebody already asked, so in distal root there is more often 1 canal :D thx for these very informative videos and keep up

Looking forward to hear from you
I’m sure the diameter at the tip is d0 and not d1. That’s how I was taught. What do we think?
Could you please explain to me the consequence of completing a root canal on a lower molar that is not tapered?
By the mandibular molars, you have your two canals in the mesial root, not in the distal^^
thankkkkk you so much ~.~
dr ryan thank you for the amazing videos. one question, doesn't file size 15 for example mean that the diameter is 0.15mm, at a 1mm distance from the tip? rather than at the tip please?
It refers to the diameter at the tip, not 1mm from the tip.
The way I remember the Crown-Down technique is thinking of Biggie Smalls' famous crown picture 🤴🏾 ;)
thank you so much
Thanks🌷
I have a pneumonic from my endodontic faculty:
Starting from the 15-file of course... "What You Really Blew Gets Better"
What = White
You = Yellow
Really = Red
Blew = Blue (duh)
Gets = Green
Better = Black
you dont have to say it was too long. I could sit and listen longer
What are the reamers used for?
More videos please
Around 13:00 you keep switching between saying 0.02mm and 0.2mm taper??
Pink (the singer) Got Pranked With Yellow Rocket Bringing Green Blankets,
thats how i remembered the colors at first
Apical seat or apical stop at 17:25?
Apical stop!
I thought the apical seat is better 😓 thank you
isn't the diameter of the tip called D0 not D1 ?
Both labels are used interchangeably depending on the source you refer to.
How to determine master apical file??
General dentists in america dont do molar endo? Strange
Some do! Most choose to refer those to an endodontist though.
