The purpose of this study was to obtain the fundamental data of the normal gingival color. The subjects chosen were 50 students female : aged 19-22 of Chiba College of Health Science, of which 14 students were eliminated due to the presence of periodontal disease. We conducted the examination of 36 students using chroma meter (shofu co.). The evaluation method of gingiva was carried out by the CIE Lab table color system. The L^* value of 36 students was minimum 45.07, maximum 64.36 and the average 56.91±4.41. Also, the a^* value was minimum 8.68, maximum 24.34 and the average 15.80±3.02. The b^* value was minimum 9.31, maximum 25.3 and the average 16.31±2.55. The 7 students in this trial for normal gingival color image were selected from 36 students oral slides by 5 dental hygienists, who had career as a clinical educator for over 10 years. The image of normal gingival color showed that L^* value was average 58.47±3.00, a^* value was average 15.64±2.67 and b^* value was average 16.09±2.17. The results showed that the image of normal gingival color was brighter and thinner color than the average normal gingival color. The normal gingival color resembled salmon pink (L^*76.05, a^*14.16, b^*16.71) which observes the thin yellow-red in the standard. The present study confirmed that normal gingival color was dark salmon pink rather than plain pink.
