    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).

      @@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.

      Hi just to offer some help... 14% is 0.14, therefore 0.14×360 = 50.4. I think that's how he got it.

    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?

    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.

    • @mentaldental
      @mentaldental  4 роки тому +2

      "Scaling" instruments is an overarching category and includes either sickle scalers or curettes. Graceys are area-specific curettes for removing subgingival calculus.
