Managing a Lateral Periodontal Cyst With Bone Graft: A Computed Tomography Assessment 18 Months Postoperatively.

The lateral periodontal cyst is a rare benign lesion that is generally asymptomatic and commonly discovered by routine intraoral radiography. Reports on proper management of this lesion are readily available. However, the literature is sparse regarding the long-term outcomes following surgery. A traditional radiographic technique does not provide an adequate image of the healing, and a patient may resist the prospect of a reentry procedure. The current report is the first to utilize a cone-beam computed tomography scan to evaluate the healing potential of a freeze-dried bone allograft approximately 18 months postoperatively.
