Radiographic examinations are very useful for endodontists to diagnose and plan efficient treatment for their patients. Until recently, 2- dimensional projections, mainly periapical radiographs, were used for treatment planning of endodontic cases with obliterated canals. However, at present, the use of cone beam computed tomography (CBCT) is the most accurate tool and its use is increasingly more frequent, especially in cases of obliteration of the root canal. Image-guided endodontics has become an alternative procedure to conventional treatment, facilitating the treatment of partially or totally obliterated root canals. While there are still no data on any clinical technique able to determine the exact location of a calcified canal, the intraoperative use of CBCT in very complicated endodontic cases can help endodontists obtain a more accurate diagnosis to perform the most adequate pro...

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 ...
