Comparative Evaluation of Fluorescence-Based Plaque Detection and Traditional Disclosing Agents: A Clinical Study

Abstract The study was aimed to evaluate the efficacy of a fluorescence-based plaque detection device compared to traditional disclosing agents. A total of 100 participants underwent plaque assessment on the facial surfaces of anterior teeth using aforementioned methods. Plaque levels were scored using the Turesky modification of the Quigley–Hein Plaque Index. White-light images from the fluorescence device correlated well with clinical evaluations, whereas red auto-fluorescence showed a moderate correlation with disclosed plaque. Participants reported higher satisfaction with the fluorescence method due to its ease of use, absence of residual staining, rapid results, and improved comfort. Fluorescence-based plaque detection demonstrates promising potential as a patient-friendly, efficient, and accurate tool for clinical use and oral hygiene education. Although limitations exist in terms of auto-fluorescence correlation, the overall benefits support broader application. Further studies with diverse populations are recommended to confirm and expand these findings.
