It involved the labial, marginal as well as attached gingiva (Figure 1).

Radiographically, both the orthopantomograph (OPG) and Cone beam computed tomography (CBCT) images showed only mild bone loss in the labial plate of lower anterior teeth (Figure 2).

At one-week post scaling, an excisional biopsy was done, and a collagen sponge dressing (FIX PLUG from Synerheal Pharmaceuticals, Chennai) was used to cover the excision site (Figure 3A and B). The use of a collagen dressing helped in the rapid healing of excision site and did not create a mucogingival defect at the excision site as seen in the one month post operative photograph (Figure 3C).

Follow-up of the patient at one year revealed a small area of focal hyperpigmentation at the site of the previous lesion which is being closely followed up (Figure 5).
