title: Dens invaginatus in a geminated maxillary lateral incisor.
abstract: Dens invaginatus (DI) and gemination are two developmental abnormalities that are well reported in the dental literature, but their coexistence in a single tooth is rare. Such situations worsen the risk factors associated with these anomalies, and the treatment plan should be customised as they possess altered morphology and anatomy. A 19-year-old girl came for evaluation of a cracked tooth in the front region of the upper jaw. The tooth showed clinical features of gemination and radiographic features of DI, and was diagnosed as DI in geminated maxillary lateral incisor. The differential diagnoses based on clinical appearance without radiographic investigation may warrant the treatment approach if these two abnormalities coexist in a single tooth. The report also highlights the importance of three-dimensional imaging in diagnosis and treatment planning of teeth with altered pulp canal anatomy. There are few reported cases in the literature detailing the treatment options for these two anomalies occurring in the same tooth.
