Quick correction! Just a minor adjustment to the instrument formula section. This doesn't impact what you need to know for the board exam, but if you're curious, the second number of the formula is actually measured as a percentage of 360˚ (similar to how the fourth number is calculated) of the cutting edge in relation to the long axis of the handle. The important thing though is this number is omitted if the cutting edge is perpendicular to the blade as we talked about in the video. I also drew the angle for the fourth number incorrectly - I should’ve drawn the supplementary angle in that case. Thanks again for watching!
Could you please clarify if this formula is the same as GV Black's instrument formula? GVB's 3 or 4-numbered formula says that the 2nd number and 4th number is measured in centigrades (100th of a circle). Thank you
@@janicem8324 Exactly! As I mentioned above, both the second and fourth numbers are measured in centigrades (a percentage of 360˚ or as you said 100th of a circle).
@@mentaldental A textbook said the number is centigrade of 100˚, not out of 360. Please see link below (page 50)
books.google.com/books?id=HgRACwAAQBAJ&pg=PA50&lpg=PA50&dq=gv+black+instrument+formula+centigrade&source=bl&ots=fEmL7YWb-h&sig=ACfU3U0zwOqffgBzYWIRx4anfq-fCWMO5A&hl=en&sa=X&ved=2ahUKEwjTqrS9na_pAhVWjp4KHXYEBWAQ6AEwCnoECAoQAQ#v=onepage&q=gv%20black%20instrument%20formula%20centigrade&f=false
@@janicem8324 Thanks for linking that textbook! To be honest though, that doesn't make sense. Centigrade is a percentage of 360˚ or a full circle. So 95 centigrade= 95% of 360˚= 342˚ for example.
@@janicem8324 where can we find you you lecture on geenral operative procedure
Don’t forget to like the individual videos... he deserves it
Dr.Ryan you are game changer,sending lots of love
Thanks Dr Ryan for excellent videos. Very well explained, to the point and very crisp. Appreciate the efforts you have taken in imparting relevant information in a very simplified method and are easy to remember.
My pleasure!
hi Rayan ,I'm here to watch the videos again from the last once year because of your great and clear explanation and also to get back the information thank u so much.
from Iraq🖤
Thank you so much, Dr Ryan! ❤️
Loving all ur lectures in a row, so simplified
I’m glad you’re enjoying the video series! 😄
Hey Dr. Rayan , you are amazing , um so greatful for all of ur efforts , thank you 🤍
Thanx immensely doc !!!!
Thank you, Ryan as always it is a great job. I only wanted to remind you that at 12:30 when talking about the 4h number it is better to draw the supplementary angle. Thank you again and good luck
Yes, good point, I should’ve drawn the supplementary angle in that case. Thank you for pointing that out!
Great lecture! Thank you.
Why this video wasn't part of the bootcamp INBDE series
we appreciate the effort
thank you so much ,great job
thank you allot , It was so helpful and I am enjoyed really
You are amazing really ❤️
Thank you!
that angle ain't 50; good video!
Thank you very much
Hello sir, I was thinking (according to some websites and photos i've seen) the second number is actually the number between the shaft's axis and the cutting edge but as I understood you said it is between cutting edge and the blade, would you please clarify if i'm wrong or not? thank you for all your incredible videos!
amazing lecture! thank you
Thank you Sir
I’m dental student ur videos helped me so much thank you
Thanks very much
Thanks💙🌿
Gracias 2.0 I´m understanding everything and english isn´t my first language
Nice lectures sir very informative
after an entire d3 year of not knowing what these are called I finally learned lmao
Thank youuu
Thank you!!!
thanks
Thak you ,nice
thank you for the great video. So when is the next video coming?
It is out right now!
great video! very informative. Just one thing with number 4, the blade angle (50 degree) is the angle formed on the left side towards the end of the instrument, not the right side one you marked. subscribed!!
In the Cutting Instrument Formula, the fourth number is a obtuse angle. It does seems like 50 degrees. Can anyone explain my question? Thank you.
hey Dr Ryan great job and many thanks for all the effort
I hope you can as well share the slides If you don't mind as we can add the notes and revise the info easily

Thank you Dr. Ryan. Can I ask you how did you get the 50 degree when our formula is 14 percentage of 360 degree? I cant understand how you get the 50 degree through this formula
Hi just to offer some help... 14% is 0.14, therefore 0.14×360 = 50.4. I think that's how he got it.
Why does the document I’m using say that 245 is preferred for peds? I agree with you that 330 is better but I’m not sure why it says 245 is?
tq
Great video as always! Was wondering how many total operative videos you were planning?
I am planning for six videos in the series, followed by our bonus video with practice questions!
memory trick for the 245...... 30 x 8 = 240
Sir, can you please tell why 4th and 6th marking is absent in William's probe otherwise video was so useful
It makes it easier to find the 5mm mark!
Can I get this presentation please.

Great video👌
I think that at 12:14 the angle of the 4th number is demonstrated wrong (you can easily recognize this because it should be 50 while the purple angle is Obtuse angle measuring more than 90 degrees)
right?
14% of 360 is 50
exactly
Hello
You mentioned in the periodontics series that Gracey is a curette. However, in this lecture you are saying that they are scalers and that the curette is not pictured. Am I missing something?
Thank you for the great lecture as always.
"Scaling" instruments is an overarching category and includes either sickle scalers or curettes. Graceys are area-specific curettes for removing subgingival calculus.
❤
How can possibly the 4th number of the cutting instrument on your example be 50 degrees if it's clearly larger than 90?
Look at the following slide. The 50˚ angle is drawn between an imaginary line extending the long axis of the handle beyond the blade and the blade itself.
@@mentaldental Oh, Thank you! :)
Why there's no videos about OMFS
There’s an entire series dedicated to Oral Surgery on my channel!
@@mentaldental Oh sorry
Hey dr. Rayan..I didn't find this vid on bootcamp with your vids...please say it's not important anymore :D... I don't like memorizing all those numbers
I’m afraid it’s still important, sorry! 🥲
How can I have your ppts?
