The “fleur-de-lys” (flower-of-the-lily) description refers to the radiographic outline of the enamel-lined infolding seen in dens invaginatus, whose coronal cross-section often resembles the stylized lily emblem. Therefore, the term is classically applied to dens invaginatus rather than to denticles, odontomes, or supernumerary teeth [Mupparapu et al., 2006, PMID 17036586].
