I failed this practical and have to retake it next week, I am so scared :( this video has been helping so much. I rewatch and drill along and it is helping so much. I have ordered the 245 bur to work on making the box the proper height and convergence. What do you recommend for getting rid of lips on the very edge of the walls and the edge of gingival floor, just the hatchet? Even when I excessively sharpen mine it chips off too much and the wall breaks off or I get sharp irregularities. I've tried everything.

@StevensonDentalSolutions 2 года назад

Make the lip very thin. Make sure your sharpened edge is at 45 degrees and not more acute.

@Ahuromazda 4 года назад

Doctor, Can you plz make a video on Endo and how to decide working length, specially with help of apex locators and the number of X rays that need to be taken during a complete Endo? Love your videos and I think many dentists out there would love to see more from you, specially in Endo and other areas. Thank you so much!

@raghavanchandrasekar2418 2 года назад

I read that the width of the occlusal cavity should accommodate the smallest condenser. Can you please explain if it means that the smallest condenser should sit on the floor of the cavity or should just the tip pass freely? Thanks

@StevensonDentalSolutions 2 года назад

Just the tip pass through the opening of the convergent occlusal. However, this statement is a rather vague and inaccurate guide, not an absolute requirement. To wit, the Oregon #1 condenser is 0.6 mm...would this now become the proper width if you have an Oregon #1? Best recommendation is to establish a 1.0 mm wide isthmus. This will meet the standards of all schools and exam boards in the US.

@afrozekhan2269 4 года назад

Hello Dr.Stevenson, For composites do we make the same prep? If so, then does the axio-pulpal line angle need to be bevelled?

@StevensonDentalSolutions 4 года назад

Smaller prep - rounded line angles, flares okay, depth about 1.25-1.5 mm, and yes an AP bevel as well. Thank you for the question.

@danapark7382 4 года назад

What would you do in case where you don’t have the enamel hatchet? What instrument would be a substitute?

@StevensonDentalSolutions 4 года назад

You could use a Bin-angle chisel or even a GMT.

@charlotteaxisa8209 5 лет назад

hi, can i ask how to get your lingual and buccal walls convergent? Is it all from a convergent bur or do you need to tilt the bur too. If so, which bur is best to create convergence, thanks a lot

@StevensonDentalSolutions 5 лет назад

Hi I’d recommend a 245 for the box and 330 for the occlusal. When refining, use an 330RGS, and never a straight fissure bur. This approach will keep the walls convergent

@charlotteaxisa8209 5 лет назад

Thanks for replying! So with these burs no tilting is required to create convergence? As i find tilting often widens the cavity too much

@StevensonDentalSolutions 5 лет назад

Correct - pretty cool

@lindak4074 2 года назад

Hi! Instead of using an enamel hatchet to remove the enamel shell, can a explorer be used? We’re doing 2nd class cavities right now and they don’t provide hatchets for us, only a mirror and a explorer... :( Is it still possible? I don’t know how else to do it, the undermined areas are killing me

@StevensonDentalSolutions 2 года назад

Nearly impossible to do without a chisel of some kind. You may be able to use a narrow bur at and angle to remove the undermined area, but be mindful of hitting the adjacent tooth, and even when you don't hit the adjacent tooth the extension (clearance) will be over-extended. Really a shame that your school fails to understand the importance of hand instruments.

@loganduncan501 2 года назад

My school doesn’t use 330 RGS. What would your next recommendation be otherwise? If you had to recommend 2nd best

@StevensonDentalSolutions 2 года назад

245

I Have #question Dr.. If the caries extended to sub gingival proximally.. How can seat the filling in the box? filled with GIC?

@StevensonDentalSolutions 5 лет назад

For amalgam, I use a #2 matrix band to extend more apically. For composite it's a whole different matter, namely margin elevation with either warm composite or preferably GIC which is packable.

Doc..i can't do the step of flaring when i transferred to the proximal surface i lose the the shape of the cavity

@StevensonDentalSolutions 3 года назад

Focus on the box form - it should be a curved rectangle and not a trapezoid shape. After this is accomplished simply blend the occlusal to the proximal carefully with a 330 but, bu removing tooth structure in the occlusal area, not the box.
