KAMBARA, Osaka Dental University, Japan Objectives:The purpose of this study was to evaluate the condition of gingiva objectively by a new digital image analysis with Quantitative Light-Induced Fluorescence (QLF). Methods:15 adults (mean age; 22-26 years old) who were informed about the aim of this study and agreed to participate, were selected as the subjects. Photographs of the gingiva were taken with an oral CCD camera (COREFRONT CORPORATION, Tokyo, Japan) and INSPEKTOR PRO(Inspektor Research Systems B.V., Amsterdam, The Netherlands). Subjects were prohibited blushing for 7 days. They were re-examined by same methods after 1, 2, 3, 5 and 7 days. The condition of gingiva was analyzed from the digital images obtained from INSPEKTOR PRO by a computer program (Inspektor-Pro 1.2.0.4, Inspektor Research Systems B.V., Amsterdam, The Netherlands). Results:On inspection, changes in the gingiva after each day could hardly be observed. However, when analyzing the images of gingiva, it was observed that a change in the color tone of the gingiva was more objectively expressed with red in the gingiva over green in the teeth fluorescence radiance that on the reference point increase, and the change of their gingival inflammation was to quantitatify with this parameter in %. Conclusions:As a result of analyzing the digital images of gingiva by QLF, it was suggested that this newly developed analyzing method could be useful for gingival examination, as changes in the quantitative value expressed the condition of the gingiva. | ||
