During periodontal plastic surgery, the necrotic bone was removed, and a free gingival graft was placed in the area.Results: After 10 days sutures were removed and 8 months later gingival healing was quite good.Conclusion: This case report shows periodontium may be damaged when fiber post drills are used to remove gutta-percha.
