Early Detection of Initial Caries Using Fluorescent Starch Nano-particles Compared With Salivary Biomarkers

Conventional diagnostic methods, including visual‐tactile examination, radiographicassessment, and caries detection systems such as the International Caries Detection andAssessment System (ICDAS), are routinely used to diagnose caries. However, these methodshave several limitations. Visual examination depends greatly on the clinician'sexperience and often detects lesions only after visible changes in enamel have occurred.Similarly, bitewing radiographs have limited sensitivity for detecting early enamellesions because radiographic changes become evident only after considerable mineral loss.Consequently, many early carious lesions remain undetected until the disease hasprogressed.In addition, saliva liquid sample had gained increasing attention as a valuablediagnostic method. Saliva contains numerous biological molecules that reflect themetabolic activity of the oral environment. Changes in salivary biomarkers associatedwith demineralization, inflammation, microbial activity, and host immune response mayoccur before obvious clinical manifestations become visible. Therefore, salivarybiomarker analysis provides a non‐invasive approach for detecting biological changesrelated to the initiation and progression of dental caries.These limitations have encouraged the development of more sensitive, non‐invasivediagnostic techniques capable of identifying carious lesions before irreversiblestructural damage becomes clinically apparent using fluorescent starch nano‐particles.One of these emerging technologies is LumiCare mouth rinse, a fluorescence‐baseddiagnostic aid that enhances the visualization of early enamel demineralization byhighlighting areas of altered mineral content. This technique has the potential toimprove the detection of initial carious lesions that may not be recognized usingconventional clinical examination alone.Recent research suggests that combining structural detection methods with biologicalindicators may significantly improve the diagnostic accuracy of early caries detection.While LumiCare mouth rinse identifies early mineral changes within enamel, salivarybiomarkers provide information regarding the biological activity of the disease.The integration of both diagnostic approaches may overcome many of the limitationsassociated with conventional diagnostic methods and enable clinicians to identify initialcarious lesions at a much earlier stage.However, limited evidence is available regarding the combined use of LumiCare mouth rinseand salivary biomarkers for the diagnosis of initial enamel caries.Therefore, furtherclinical investigation is required to evaluate whether this combined approach offerssuperior diagnostic performance compared with conventional methods.
