Understanding the spatial and topographic characteristics of enamel white spot lesions for targeted remineralization.

Introduction: White spot lesions are opaque, chalky white or yellowish discolorations on the surface of teeth that result from the demineralization of the tooth structure. Many methods, including SEM, XRD, and FTIR spectroscopy, are crucial for identifying and evaluating enamel white spot lesions. It is imperative to have a thorough grasp of the morphology, crystallographic structure, mineral composition, and chemical changes associated with enamel white spot lesions.
