Orthodontic management of a dental concrescence: a case report. Dental concrescence is a rare dental abnormality resulting in the joining of two teeth at the level of the cementum. This is the first reported case of the orthodontic management of a dental concrescence and the options for patient treatment are discussed. In this case, a compromised occlusal result was accepted with restorative
Concrescence: Cone-Beam Computed Tomography Imaging Perspective Concrescence is a form of twinning, formed by the confluence of cementum of two teeth at the root level. The diagnosis of concrescence has largely relied on the conventional 2D imaging. The 2D imaging has inherent limitations such as distortion and superimposition. Cone-Beam CT eliminates these limitations. The aim of this article was to describe a case of dental abnormality using Cone-Beam CT imaging modality. Volumetric data demonstrated confluence of left mandibular third molar with a paramolar, a supernumerary tooth. To our knowledge, this is the second case in the dental literature reported demonstrating the use of Cone-Beam CT in the diagnosis of concrescence.
Unusual finding of concrescenceConcrescence is a rare dental anomaly whereby adjacent teeth are united by cementum. It has been reported to occur in around 0.8% of permanent dental extractions and a correct diagnosis prior to surgical intervention is important to ensure that patients can make an informed decision about their treatment and to reduce the potential for dentolegal action against of concrescence was established. The patient was informed of the complication and provided with a 1-week review appointment, at which stage she was discharged.
and radiographic examinations, one was diagnosed with fusion, and the other was diagnosed with concrescence. The crown of the fused incisor was separated using a burs and extracted intraorally. The concrescent incisor was separated along its length using a laser and intentionally replanted extraorally. After a 6-year follow-up, no pathological signs were observed in the fused incisor. However, after an 11-year follow-up, external resorption was observed in the concrescent incisor. Both incisors remained asymptomatic throughout the observation period. This case report highlights two different and effective methods employed to preserve the natural function, form, and aesthetics of double incisors.

Triple tooth in primary dentition: A proposed classification Triple teeth may result from fusion, gemination or concrescence causing transient esthetic and functional problems in primary dentition and retardation or alteration of development and eruption of permanent successors. We report an unusual case of a boy aged five with fusion among maxillary left primary central incisor, lateral incisor
staining. TEM observation showed there were typical chondrocytes in the reparative tissue in group B, while parallel or interlaced arrangement collagen fiber existed in groups A and C. Combining mosaicplasty with tissue engineering methods can solve the problem caused by single use of mosaicplasty, including the poor concrescence of the remnant defect and poor integration with host cartilages.
Concrescence of a mandibular third molar and a supernumerary fourth molar: report of a rare case. Concrescence represents a rare developmental anomaly in which two fully formed teeth are joined along the root surfaces by cementum. Maxillary molars are the teeth most frequently involved, especially a third molar and a supernumerary tooth. Very few cases have been reported about the concrescence of a third molar and a supernumerary tooth. According to our current knowledge, this case report is the first in the literature in which concrescence is observed between a third molar and a supernumerary fourth molar in the mandible.
with appropriate radiographs. A comprehensive clinical examination was performed to detect hyperdontia, talon cusp, fused teeth, gemination, concrescence, hypodontia, dens invaginatus, dens evaginatus, macro- and microdontia and taurodontism. Patients with syndromes were not included in the study. Of the 20,182 patients screened, 350 had dental anomalies. Of these, 57.43% of anomalies occurred in male patients
of hemifacial hyperplasia.Abnormality in shapeThe fusion of two deciduous teeth * Gemination occurs when a developing tooth incompletely splits into the formation of two teeth. * Fusion is the union of two adjacent teeth during development. * Concrescence is the fusion of two separate teeth only in their cementum. * Accessory cusps are additional cusps on a tooth and may manifest as a Talon cusp, Cusp
