Abstract:
Dilated Composite Odontoma also known as Dens invaginatus, "dens in dente", or "tooth within tooth" is a rare dental anomaly resulting from enamel organ infolding during tooth development, often leading to complications like caries and pulp infection. With a prevalence of 7.45%, it commonly affects upper lateral incisors, predominantly as a Type I morphology. Mesiodens, a supernumerary tooth in the anterior maxillary midline, occurs in 89.7% of single cases and 10.3% of bilateral cases. The coexistence of dens invaginatus in a mesiodens is extremely rare, posing diagnostic and treatment challenges. This report presents a unique case of dentin invagination in a mesiodens.
