Some confusion with a few viewers: "The point of bur entry is within the incisogingival dimension of the carious lesion or defective restoration and as close the the adjacent tooth as possible without contacting it. Direct the bur PERPENDICULAR (90 degrees) to the enamel surface..." Sturdevant, "The Art and Science of Operative Dentistry" Angling the bur at a 45 degree angle undermines the incisal enamel.
@StevensonDentalSolutions6 жыл бұрын
One more thing: For an MF (facial approach) the bur is initiated at a 45 degree angle and the facial enamel is left undermined, but this works because the facial surface isn't under function. This is done primarily for esthetic reasons.

There is this thing I am confused about. I was always taught to always use diamond burs to prep the enamel but I see a lot of US dentists to use those high speed carbide burs, whether it is crown prep and now a cavity. Could you please talk more about thee difference? Doesnt the bur have rather shattering effect?
@StevensonDentalSolutions5 жыл бұрын
In the early days of operative dentistry, carbide steel was the only technology known to make burs. It wasn't until much later, in the 1970's and 80's that diamonds really become commonplace in dental practices and textbooks. The more recent development of operative diamonds has taken some time to catch on, and although great for less chatter when penetrating enamel, they are relatively costly and not as precise dimensionally compared to carbides. If you were to peruse the two most significant Operative texts in the US - by Sturdevant and Summitt, you'll see that the carbide remains as the go to instrument for conservative preparations.
@sahilbhalla3892 жыл бұрын
Crisp and clear knowledge 👌 . I have 2 ques: 1. Which operator position would you suggest to prepare class 3 cavity on Distolingual surface of tooth no. 12 ( first quadrant lateral incisor)? I find it difficult to access this surface while keeping the bur perpendicular to tooth and using a hatchet to smooth the walls feels impossible. 2. I am currently using 3.5x magnification for restorative work required for the exam. Do you think i should switch to 4x or 4.5x to make my work more intricate for the examiner to check 😅 what according to you will be the sweetspot for magnification for a dental student?
@StevensonDentalSolutions2 жыл бұрын
1. Use the 11 O'Clock position but have the patient turn away from you - this help. 2. I siwtched from 2.5x to 4.5 x after two years and then 2 years after that ramped up to 6x. I also use a microscope. If you can, push the mag as high as you can - you'll quickly adapt. 4.5x isn't that high, so you should do well.

no need for class III's that are approached from the lingual and do not extend facially - lots of enamel exists for retention, and blend for esthetics is not critical on the lingual. Finally, the thin area of composite created by a bevel is more susceptible to fracture from occlusion...Bevels for class IVs are essential.

Bevels are rarely employed anymore on class III's unless: 1. they extend onto the facial and require an esthetic blend, 2. The are large and require additional retention. The US licensing exams not only don't require them, but would prefer they not be beveled. When a bevel IS indicated, full enamel thickness, followed by an infinity bevel or starburst is great for facial surfaces.

Hi Dr Stevenson, I have a question which might sound stupid. For all preparation of teeth ,from examiner point of view, what power loupes you recommend for practice? I got two loupes (3x and 6x) and my preparation seems very clumsy under 6x which seems fine and smooth under 3x. If we know what power loupes examiner will be using for marking, it'll be very helpful for students. Thanks...
@StevensonDentalSolutions6 жыл бұрын
Great question! Most dental school faculty and WREB/NERB examiners use 3.5x - 4.5x loupes. If the prep is smooth at 3.5x, it will always look less smooth at 6x. Using 6x takes many hours of practice and isn't initially practical. Do the best you can at 3.5x and you'll be in the "Green Zone" if you've met the criteria.

@StevensonDentalSolutions3 жыл бұрын
Great Questions! Thank you. Bevels are no longer in favor for small preps with no esthetic margin concerns. If the prep has ample retention and has no need to be "esthetically blended" with the use of a bevel, a bevel is not used. The bevel would not only remove tooth structure and it would render composite susceptible to fracture (as it is thin) due to occlusal contacts. Note: both the WREB and ADEX dental licensure exams removed the bevel requirement on the class III several years ago, in keeping with the science and teaching practices within the US. IF, the prep extended onto the facial, we would bevel the facial margin (esthetic blending) or IF the prep were large and needing retention, we would bevel all accessible margins. Bevels aren't contra-indicated in all preps, rather the algorithm for their use is more sophisticated. Dr. Stevenson
