The aim of this study was to suggest a convenient method of monitoring the gingival state through plaque detection. Quantitative Light-InducedFluorescence-Digital (QLF-D), which can assess mature plaque, can be used to assess the oral hygiene status of individuals and to establish anadequate intervention plans for them. The subjects of the study participated in the clinical training at Department of Dental Hygiene, N University. The subjects completed questionnaires on general characteristics and oral hygiene methods. Then, photographs of maxillary and mandibularanterior teeth of the subjects were taken using the QLF-D. After the oral examinations, gingival state was recorded according to the Löe & Silness'sGingival Index (GI). In addition, a plaque control record was calculated in percentage using disclosing agent. The analysis of the relation betweenthe plaque control record and the QLF-D scores showed positive correlation (r=0.638, p＜0.001), and the analysis of the relation between theQLF-D scores and the gingival bleeding index scores also showed positive correlation (r=0.562, p＜0.001). Besides, the study classified theparticipants into healthy gingiva group and the gingivitis group according to the classification criteria of GI, and when the difference of QLF-D scoresbetween the groups was analyzed, the QLF-D scores were statistically significantly higher (t=－2.785, p=0.007) in the gingivitis group (1.71±1.545)than the healthy gingiva group (0.74±1.290). When the differences in mean values of the QLF-D scores were analyzed against and the gingivalbleeding index scores, the QLF-D scores of 0 and 1 belonged to the category of normal gingival state while the QLF-D scores of 2, 3 and 4 belongedto the category of gingivitis state. Therefore, it is deemed that the red fluorescence detected by the QLF-D from the mature supragingival plaquecan be used for monitoring the state of gingivitis.
Abstract
The aim of this study was to suggest a convenient method of monitoring the gingival state through plaque detection. Quantitative Light-InducedFluorescence-Digital (QLF-D), which can assess mature plaque, can be used to assess the oral hygiene status of individuals and to establish anadequate intervention plans for them. The subjects of the study participated in the clinical training at Department of Dental Hygiene, N University. The subjects completed questionnaires on general characteristics and oral hygiene methods. Then, photographs of maxillary and mandibularanterior teeth of the subjects were taken using the QLF-D. After the oral examinations, gingival state was recorded according to the Löe & Silness'sGingival Index (GI). In addition, a plaque control record was calculated in percentage using disclosing agent. The analysis of the relation betweenthe plaque control record and the QLF-D scores showed positive correlation (r=0.638, p＜0.001), and the analysis of the relation between theQLF-D scores and the gingival bleeding index scores also showed positive correlation (r=0.562, p＜0.001).

Therefore, it is deemed that the red fluorescence detected by the QLF-D from the mature supragingival plaquecan be used for monitoring the state of gingivitis.
