Also if any of your dentists buy one of these . make sure they keep the "calibration-block" clean and recalibrate every time they use it ! After recalibration put it in "Shade Tab" mode and scan the shade tabs - as it can regularly give false readings ! When taking tooth shades use it in "Tooth- Area" mode - ie three separate readings , cervical area , body area,and incisal area.The one shade mode ( can`t remember what its called ) is a waste of time as it just gives an average shade. Also if its set in 3D shade mode as opposed too "Classic" you will end up with lots of interpolated shades-ie a mixture of 2 X 3D shades ! Pain in the ass if you don`t have every 3D shade in the lab !! I does not read translucency
- therefore it will give you an incisal reading like "EN1" etc. Its pretty basic, so you need to interpret the true characteristics by "Eye & Photograph" I think a nice DSLR
, macro lens (105mm for patients) and a dual flash would be money better spent - and you will have money to spare
