Solitary/single median maxillary central incisor syndrome indicates the presence of a single median maxillary central incisor together with other midline defects of development. A single maxillary central incisor not positioned in the midline indicates agenesis of the contralateral central incisor and can be differentiated furthermore by the morphology of the crown. A diagnosis of a solitary median maxillary central incisor typically requires X-ray examinations.
