The skeletal remains of G iovanna of A ustria (1547–1578), daughter of the E mperor F erdinand I of H absburg (1503–1564) and first wife of the Grand D uke of T uscany, F rancesco I (1541–1587), exhumed from the B asilica of S an L orenzo in F lorence, were submitted to paleopathological study. Examination of the dentition, which was in a good state of preservation, showed maxillary retrognathism, together with a caries lesion, moderate periodontal disease, malposition of the upper second premolars and tooth wear. Furthermore, several horizontal grooves were observed in both the buccal and the lingual crown surfaces of almost all teeth, especially the anterior ones. The orthopantomogram showed hypomineralized enamel and alveolar bone loss. Two third‐molar teeth were investigated using micro‐computed tomography (micro‐ CT ) analysis, revealing highly irregular enamel caps with reduced average thickness. The observed features suggest a diagnosis of hypoplastic amelogenesis imperfecta, a developmental condition affecting enamel formation.
