The report reviews the color determination of gingiva by a new measuring system and the accuracy of the system. Pathological change of gingiva has been determined and evaluated by personal experience of the researcher's eye. Realizing this points, the authers commenced a study of this problem and recently successful result has been obtained.
Gingiva, as a soft tissue, is not only unsteady but also uneven on the surface. There are two possible solutions to the problem; in the first place, we must describe each datum exactly, and the second place, we must obtain the data repetitionary. A new measuring system which was used in this study is the best of the countermeasures answering the request. We also performed the fundamental experiment to determine whether assumption used in the standardization is good or not. In this research, the strongest correlation was observed between measuring distance and the data, the most reliable distance was 0.05mm from the tip to gingiva.
