Coexistence of fusion and concrescence of primary teeth: in a child with Down syndrome

Concrescence of maxillary second molar and impacted third molar: A case report

BACKGROUND

Morphological anomalies of teeth, including talon cusp, dens evaginatus, gemination, fusion, concrescence, root dilaceration, and taurodontism, always involve changes in the enamel, cementum and dentin. Diagnosing concrescent teeth through routine clinical examination alone is difficult, and most cases of concrescence are found accidentally during extraction. A definite preoperative diagnosis of concrescence would contribute to a better treatment plan and fewer undesirable complications

CASE SUMMARY

A 47-year-old woman who complained of left maxillary first molar loss for half a year presented to our department seeking treatment by dental implant restoration. Panoramic radiography and cone-beam computed tomography (CBCT) showed an unclear boundary between the distal root of the second molar and the mesial root of the third molar. The teeth were extracted under local anesthesia, and a definite diagnosis of concrescence was made by histopathological examination.

CONCLUSION

CBCT is a useful tool for diagnosing and planning the management of tooth concrescence and may be beneficial for reducing unnecessary complications.

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 masking of the affected teeth.
