An acrylic model of upper left anterior teeth(11,12,13),lower anterior(41,42,31), lower right posterior teeth (44,45,46)and lower left posterior(34,35,36) was prepared in typhodont with the standard set of burs which is suitable for ceramic preparation was used to achieve the controlled tooth substance removal.The preparation featured a 1.5mm occlusal height reduction, a 1mm of chamfer ended margin and an axial reduction of 1.5mm SPRAYING AND DIGITILIZATION: A totally 12 prepared tooth placed in the typhodont with the normal adjacent teeth and the typhodont mounted on the fantam head after mounting, sparying were done in all surface of tooth (labial,lingual,mesial,distal) including occulsal surface and tooth were equally sectioned in two halves in a horizontal direction using cardamom disc. After dissection sony digital SLR camera are choosen to take photos of sparyed tooth of each surfaces and this RGB images are converted into grayscale by using gray scale photo effect generator .After converting the image where thickened spray areas were appeared dark and thinner portions of the spray appear lighter so those converted images are kept at constant 66.7% magnification and measured as inches using klonk image measurement application.and thereby measuring pixel density of the thinner and thicker portions of the prepared tooth surface using pixel density calculator .Calculating the diagonal resolution in pixels using the Pythagorean theorem:
