“…The tomography and its beautiful images, 5,6 including 3D, have provided a very accurate diagnostic acuity and allow an accurate diagnosis of dental concrescence based on very precise conceptual and imaging criteria applicable to all specialties of human knowledge. [7][8][9][10]…”

The atrophy of the periodontal ligament places the tooth very close to the bone or another tooth, as occurs in unerupted teeth. The absent interdental bone and the lack of functional periodontal stimulus may lead to the fusion of the appositional layers of cement between the roots of the teeth. Concrescence almost always occurs in the region of the maxillary molars. Asymptomatic, it should always be remembered when the proper response to orthodontic movement is not obtained, and there is no apparent explanation. When surgically extracting a tooth and there is resistance, insisting will not be the best strategy. Moving the teeth with concrescence is not convenient, as it requires very intense forces. Once separated, these teeth can be considered normal for movement. It is possible to separate two teeth presenting concrescence, but it depends on the extension of the area, the surgical access and, especially, the clinical convenience. The tooth to be extracted will be repaired with new cement deposited in the sectioned area. The simple separation with the maintenance of the proximity and the lack of function of one of the teeth will cause a new concrescence. After a period of 1 to 3 months, the separated teeth are biologically prepared to be moved. The most important detail in this separation of teeth presenting concrescence is that the diagnosis should be made in advance, and not at the time of the intervention.

“…16 Also, CBCT will best show cementum connection. 40 Dens invaginatus is an anomaly that occurs on teeth presenting calcified layers invaginated in the dental pulp, forming a new tooth inside the tooth itself. This condition usually occurs bilaterally, with the most affected tooth the maxillary lateral incisor.…”

Dentists and oral and maxillofacial radiologists have used periapical, occlusal, panoramic, and cephalometric radiographs for many years for diagnosing dental anomalies, especially before orthodontic or surgical treatment. Cone beam computed tomography was developed in recent years especially for the dental and maxillofacial region. Thus it has become the imaging modality of choice for many clinical situations, such as the assessment of dental impaction and structural teeth anomalies or other associated diseases and disorders (e.g., Gardner's syndrome, cleidocranial dysplasia). This article reviews different aspects of dental impaction and its possible effects on adjacent structures such as external root resorption, marginal bone loss, as well as describing structural dental anomalies. It provides a systematic analysis of their characteristic features and imaging findings for general radiologists to achieve a precise diagnosis and an optimal interpretation.

“…Concrescence is a rare developmental dental alteration, which may be influenced by environmental factors in its etiology, such as trauma, infections, inflammatory reactions, among others (Neville, Damm, Allen &Chi, 2016 andSugiyama et al 2007). However, its etiology is still not fully understood (Syed, Alluri, Mallela &Frazee, 2016 andRomito, 2004). Its development can occur in two different stages: first during root formation, being classified as true concrescence, and after complete root formation, being denominated as acquired concrescence (Gunduz, Sumer, Sumer & Gunhan, 2006).…”

“…Recent studies have shown no predisposition for a particular ethnicity, age or gender (Syed et al 2016 andKardach, Sobieszczyk &Sokalski, 2016). And the incidence of concrescence in extracted teeth is 0.8% in permanent teeth and 0.2-4% in the deciduous dentition (Syed et al 2016 andForan, Komabayashi &Lin, 2012). The concrescence was describe as the union of two adjacent teeth by a cementum layer, which is usually deposited among the roots, without the confluence of dentin; therefore, they are two independent teeth, regarding the crowns, roots and pulpal canals (Syed et al 2016 andGunduz et al 2006).…”

Can concrescence diagnosis be obtained merely by clinical and imaging examination? from clinical case to histology

Concrescence is a rare type of union of two teeth, with no predisposition for a particular ethnicity, gender or age, specifically united by a portion of cementum, without the fusion of dentin, commonly reported in the posterior maxilla region, in most cases, this anomaly affects the second and third molars. Its diagnosis is suggested by radiographic images when there is proximity between two teeth, without signs of the periodontal ligament, or interdental bone between them, often showing a radiographic overlap. The lack of attention to these signs can lead to complications during endodontic and surgical procedures, such as unplanned extraction of the involved teeth, even leading to legal problems. The aim of this paper is to report a histologically proven case of concrescence between an erupted second molar largely compromised by caries and an impacted third molar, in addition to presenting a literature review, along with the histological aspect, about the subject.
