Title: The color of gingiva studied by visual color matching. Part I. Experimental studies on the discrimination threshold for color difference and effect of training.
Abstract: As a preliminary experiment on the gingival color indicated by Munsell system, the makings or the qualities for color sensation of the individual were checked with regard to (1) discrimination threshold for color difference with certain color range of gingiva (paired difference test for color comparison) and (2) promotion of memorial power by training (test for memory color). A total of 20 males and females (20-30 years old) participated in this preliminary study as experimental subjects and the following results were obtained: (1) the average color discrimination threshold for color difference among subject trained for color memory is 0.8 Lab. (Hunter), and is assumed to be greater in the actual colorimetry of gingiva, (2) the similarity of discrimination is more frequent among the subjects trained for color memory than among those who were not trained, and (3) training for color memory is found to be effective in promoting the ability for color discrimination.
