For many years, observation of gingival color has been a popular area of dental research. However these methods are hard to analyze for any other than the different base conditions and colors. Thus we introduced an alternative method using image analysis to measure gingival color. For the research we performed a dental examination on 30 female students.The system is set up by aligning the camera area and facial area. The subjects chin is placed in a fixed chin cup mounted 30 cm from the camera lens. Each image is acquired such that comparison may be made with the original bite holder as well as a standard color scale. After converted to computer we used a curves dialog box for color adjustment. The curves dialog box allows adjustment of the entire tonal range of an image.The results of the analysis of the free gingiva compared to the attached gingiva are that attached gingiva was more vivid red and yellow compared to the free gingiva. In conclusion, the system described herein of digital caputre and comparison of color images, analysis and separation in three channels of free and attached ginigval surface images and matching with colorimetric scales may be useful for demonstrating the diversity of ginigval color as well as analysis of gingival health.
