THE IMPORTANCE OF CHOOSING THE APPROPRIATE DENTAL COLOUR
Abstract
Introduction Dental colour is mainly formed as a result of the interaction of light with the enamel that dispels it in the blue range of colour and together with the dentine where the absorbtion and reflection of light takes place. The process of choosing the appropriate dental colour is a difficult one, that we have to undertake on a daily basis in our individual dental practice both when restoring just one tooth but also when dealing with more difficult complex cases. Aim of the study The aim of the present paper is to appreciate the precision technique in determining the brightness of two modern colour keys like 3D keys, Toothguide 3D Master and Linearguide 3D Master, using as comparative models the values resulted from the usage of the VITA Easy Shade Advance spectophotometer. Material and methods 252 frontal teeth were carefuly selected according to strict criteria. The colour was selected both visualy using the Toothguide 3D Master and Linearguide 3D Master keys as well as the VITA Easy Shade Advance. The brightness was focused by using the CIELAB values. The difference in brightness for each group of frontal teeth were calculated. Results After analysing the differences in brightness for each group of teeth it has been determined that these differences were lower in the case of Toothguide 3D Master key than for the Linearguide 3D Master key. Conclusions The differences in brightness are better highlighted with the help of the Toothguide 3D Master key as compared to the Linearguide 3D Master key.
