Multiple idiopathic cervical root resorptions: report of one case with 8 teeth involved successively

Abstract

Multiple idiopathic cervical root resorptions is a rare condition which is usually detected as an incidental radiographic finding. It involves more than 3 teeth in the same patient and the etiology remains elusive. Diagnosis and treatment of the defect is still challenging. The present report describes a case with progressive multiple external cervical resorption involving 8 teeth, including the history, clinical and radiographic findings. Treatment included surgical intervention and restoration of the defect. A 3-month reevaluation of the case confirmed a stable, uneventful clinical recovery.

Keywords: External root resorption; cervical lesion; tooth defect.

Panoramic radiograph showed radiolucency at the distal surface of 41, both mesial and distal surfaces of 42, mesial surface of 43.

Figure 2

Panoramic radiograph showed both mesial and distal surfaces of 31, 44, the distal surface of 32, the mesial surface of 45 were involved.

Panoramic radiographs and periapical radiographs of the involved teeth. A. Panoramic radiograph showed radiolucency at the mesial surface of 46. B. Periapical radiographs showed radiolucency at the mesial surface of 46. C. Periapical radiographs showed radiolucency at both distal and mesial surface of 31, mesial surface of 32.
