Case Description

Evaluation and Treatment

The dental hygiene student noted the pockets on the central incisor had increased 2-3 mm over previous readings and also detected a hard, seemingly immoveable, ledge-like projection on the root surface near the base of the pocket.  The patient was unaware of the pocket, experienced no tenderness or bleeding, and reported no memory of a specific injury or trauma to the area.

A referral was made to the Graduate Periodontal Residency Clinic where flap surgery was performed.  A partially detached cemental tear fragment was evident at the base of the pocket that was removed by root planing (Figure 2).  A graft with .75 mg Biogran^® was placed in the defect together with a resorbable membrane and the flap was replaced and sutured (Figure 3 and 4).
