Fundamental Study in Measurement of Gingival Color

Measurement Apparatus and Conditions of Measurements

Abstract

From the standpoint of diagnosing the condition of the gingiva as well as esthetics, gingival color is found to play an important role in dentistry. Thus, it is important to be able to differentiate the changes in color of the portion of gingiva which is in contact with the crown. We the authors of this report, decided to measure the gingival color and make basic investigations pertaining to the conditions in relation to color measurements. The results revealed the following.
It was possible to accurately measure the marginal and papillary gingiva using the modified version of the CD-270 colorimeter, which is considered to be one of the most accurate source of equipement in differentiating color shade.
The detectable color differentiation limit among the dentist of our department was found to be 1.12.
The fixation apparatus for the colorimeter was found to show stable and repeatable data.
It was possible to be able to control the color difference below the afore mentioned detectable color differentiation limit value by a constant color setting established by our department.
