Endodontic Management of a Mandibular Incisor Exhibiting Concurrence of Fusion, Talon Cusp and Dens Invaginatus using CBCT as a Diagnostic Aid

[Dens invaginatus or dilated odontoma, a definition controversy.]

The invaginate tooth (IT) is an alteration in the development of the dental organ, which occurs as a consequence of invagination of the internal epithelium of the enamel organ. IT is also known as "dens in dente", among other denominations, and presents a series of clinical, histological and imaging characteristics. The most extreme variant of IT has a very complex configuration, and the magnitude of the intussusception has led to it also being called dilated odontoma, being a term that generates confusion in some professionals.While the term odontoma has been reported as a synonym for both IT as well as a new variant of odontomas, there is a difference betweene the two types: one is a developmental anomaly and the other is a growth with a hamartomatous appearance. However, the literature continues to use both terms to define IT, and thus, it is important to know the origin and be aware that the controversy is based on historical and customary references.

Multiple talon cusps on maxillary central incisor: A case report

Dental anomalies affecting the teeth are relatively common. Simultaneous occurrence of multiple dental abnormalities in a single tooth is uncommon and relatively rare. One such abnormality routinely encountered in dental clinics is the talon cusp. It is also referred to as dens evaginatus, characterized by the presence of an accessory cusp-like structure projecting from the cingulum of anterior teeth. It has an increased predilection for maxillary teeth and permanent dentition. Although numerous cases of talon cusp have been reported in the literature, occurrence of multiple talon cusps in maxillary central incisors has not been found in the literature. This case report highlights the presence of talon cusps in maxillary anterior teeth with multiple impacted supernumerary teeth.
