Subject: [roots] second molar crown prep through the scope. a picture sequence..

All photos were essentially un altered for centering to allow for the awkard feel and limited view at times.

There is lots of scope movement when I do a crown prep

Slide 1: pre op direct view through scope
Slide 2: aerial preop view
Slide 3: alloy removal to verify and locate that tooth was actually cracked arrow marking crack
Slide 4: in same view the occlusal reduction and buccal reduction
Slide 5: a slight twist and movement of the scope gives a look right through the mesial interproximal..
         (noting the value of the rubber dam for cheek retraction and the value of high magnification which
         allows one to look right down the side of the rubber dam to the area of interest without confusion
         of the eye). As well, another slight twist and movement of the scope allows an almost direct view
         down the distal (again, the value of the rubber dam and scope)
Slide 6: movement of the scope, set up and actual view  for lingual reduction
Slide 7: lingual reduced
Slide 8: aerial view ..evaluating corners and connecting of dots..
Slide 9: all corners rounded, dots connected, radiosurg accomplished, and prep cleaned and refined with ultrasonics
         ready to drop the cord and set up for impression
