Dens in dente, also known as dens invaginatus or dilated composite odontoma, is a rare dental anomaly characterized by an unusual malformation that occurs during tooth development. Derived from Latin, "dens in dente" translates to "tooth within a tooth," which perfectly describes the nature of this condition.
In dens in dente, a deep invagination or folding inward of the dental enamel and dentin occurs, resulting in the presence of a small tooth-like structure within the affected tooth itself. This developmental defect typically affects the permanent teeth, most commonly the lateral incisors, although it can also affect canines and premolars.
The etiology of dens in dente is not yet fully understood, but it is believed to arise from an abnormality during tooth formation wherein the tooth germ folds or enfolds upon itself. This abnormal invagination creates a cavity that is prone to bacterial accumulation, leading to increased susceptibility to tooth decay, infection, and other oral complications.
Clinically, dens in dente can be diagnosed through radiographic imaging, which reveals the invagination and the presence of the additional structure within the tooth. Treatment options may vary depending on the severity of the anomaly, with conservative dental procedures such as composite resin restoration or endodontic therapy being common approaches. Extraction may be necessary in severe cases where restorative methods are not feasible or have failed.
Overall, dens in dente is a dental anomaly characterized by an inward folding of tooth enamel and dentin, resulting in the formation of a miniaturized tooth-like structure within the affected tooth. Early diagnosis and appropriate treatment are essential to prevent complications and maintain oral health.
