ABSTRACT

Accurate mimicking of human tooth colour for restorative purposes is since long an enigma to both the dentist and Lab technician. The purpose of the study is to determine validity of combination of digital photography and conventional method of shade selection using shade guide for accuracy in matching colour of human tooth over only conventional method of shade selection. 30 volunteer are selected randomly from dental students studying in dental college. These are grouped under 2 of 15 each. First group to be used for shade selection by 5 different operator plus digital photography and second group to be used for shade matching by conventional shade guide only by same 5 operators. Shade selection to be done under controlled illumination and time period. All digital images to be analysed on computer screen to help technician make an accurate observation. Technician asked to match tooth colour on standard metal framework for both groups. Prepared PFM crown to be evaluated clinically for accuracy of shade matching and validity of combination method over conventional method of shade selection. Aim-To determine validity of combination of digital photography and conventional method of shade selection for accuracy in matching colour of human tooth over a conventional method of shade selection using shade guide.Objectives- 1)To Select a shade of human natural teeth with the help of shade guide viz. Vitapan classical by five different operator.2)To digitally evaluate shade of teeth whose shades have been selected by operators.3)To Communicate with lab technician about mimicking of shade. 4) To verify shade matching clinically.
