Palatal radicular multigrooves associated with severe periodontal defects in maxillary central incisors

This case report describes a rare condition of palatal radicular multigrooves on teeth 11 and 21 with severe periodontal defects and the findings at 3-year follow-up.

Radiculoplasty using hand curettes and rotary burs were used to remove the multigrooves on the root surfaces and change the wrinkled root form to the relatively flat and smooth normal root morphology. Minor tooth movement and frenotomy were performed for a diastema between teeth 11 and 21. Supportive periodontal therapy started immediately after completion of the active treatment.

Improved healthy periodontal tissues and adequate plaque control have been maintained.
