Kurzfassung

Visual colour determination, by comparison of the tooth with standard colour tooth shade guides, is the most frequently applied method in dentistry. It is a subjective process whereby the tooth and the shade guide are observed simultaneously under the same lighting conditions. General variables such as external light conditions, experience, age, and fatigue of the human eye and physiological variables such as colour blindness may lead to inconsistencies.

It is a subjective process whereby the tooth and the shade guide are observed simultaneously under the same lighting conditions. General variables such as external light conditions, experience, age, and fatigue of the human eye and physiological variables such as colour blindness may lead to inconsistencies. Despite these limitations, the human eye is very efficient in detecting even small differences of colour between two objects. The aim of this in vitro- study was to evaluate the conformance of equal shade guides (Vita classical; Vita Toothguide 3D Master; Vita Linearguide) using a clinical spectrophotometer.» weiterlesen» einklappen
