QUANTITATIVE LIGHT-INDUCED FLUORESCENCE IN THE DIAGNOSIS OF WHITE SPOT LESIONS: PRINCIPLES, APPLICATIONS, AND CLINICAL RELEVANCE

Abstract

White spot lesions (WSLs) are early signs of dental caries and are characterized by demineralization of the enamel surface. Timely detection and monitoring of WSLs are crucial for effective preventive and therapeutic interventions to halt their progression. Quantitative Light-induced Fluorescence (QLF) has emerged as a promising diagnostic tool for the early detection and quantitative assessment of WSLs. This review aims to provide a comprehensive overview of the principles, methodologies, and clinical applications of QLF in diagnosing WSLs. The underlying principles of QLF, including its interaction with dental tissues and the fluorescence properties of demineralized enamel, and methodological aspects, such as image acquisition protocols, software analysis, and interpretation criteria, are critically evaluated. Furthermore, the diagnostic accuracy, reliability, and reproducibility of QLF in detecting WSLs were systematically reviewed based on the available literature. The challenges and limitations associated with QLF, including its reliance on operator proficiency, calibration procedures, and potential confounding factors, have been identified. This review highlights the significance of QLF in enhancing the early detection and management of WSLs, thereby contributing to optimal oral health.
