[SavigeBlazer]

why does the skin above the tooth that is being worked on has a different colour during the prosideure ?

@drnoosaya practice indirect vision more

[dashark79]

they are working on a plastic model without water for better visualisation... I'm sure they'd use coolant spray in the mouth of a live patient!

@bafan4lifehotline the white is the powdered tooth as it doesnt look like they are using water spray, which they should by modern standards but this movie is really old so perhaps they didnt use water cooling then :)

It's strange how enamel, the hardest bodily substance, is casually removed by a such a small tool.

@muneco0211 dimonds rotating at speeds of 400,000 rpm, not so strange really lol

can anyone tell me what burs are used in this preparation? and is the finishing line shoulder and champhor?

and lastly, are the grooves labially, made after the finishing line is done with? i thought u made the grooves first. thanks.

[andypandyhu]

@ammhn88 in my opinion the burs that were used are as follows. round bur first for front and depth groves, the needle point for interproximal to avoid damage to neighbouring teeth, normal torpedo for palatalside gingival area and just general shaping of front, and oval shaped for the lingual fossa/cingulum area with no depth groves formed. looks to me like it was a chamfer preperation.

i guess its 9months late but you asked so i thought i would give you my ideas lol ;-P
