(a) A deep periodontal pocket and drainage of pus through the gingival sulcus are visible. (b) Radiographs of tooth #22 exhibit (i) a large lateral radiolucency on the mesial tooth surface extending from the bone crest to the root apex, (ii) calcium hydroxide [Ca(OH)2] placement, (iii) root canal obturation, and (iv) bone healing. (c) Surgical exposure of tooth #22 shows calculus accumulation and granulation tissue mesially with the absence of buccal bone. (d) Removal of calculus and granulation tissues and placement of the bone graft. (e) Placement of the barrier membrane; the 30-month recall photograph shows normal gingival tissue.
