case_images: (a)-(d) Deep pockets were present even though signs of gingival inflammation other than bleeding on probing were absent.

case_images:  An OPG and full-mouth IOPA X-ray were performed which revealed the generalized distribution of alveolar bone loss which was a combination of both horizontal and vertical bone loss (Figure 7).

case_images: A modified Widman flap surgery in conjunction with bone replacement graft was performed in the molar regions (Figures 8(a)-8(e)) whereas a sulcular incision flap (Kirkland flap) was performed in the maxillary and mandibular anterior region to minimize the recession after healing for esthetic purposes. Healing was uneventful, and a postoperative evaluation 3 weeks after surgery showed absence of bleeding on probing and probing depths within normal limits (Figure 8(f)). A postoperative radiograph 6 months later showed a significant bone fill in the molar regions where grafting was done with an increase in bone density of the alveolar crest with corticated bone formations in the crest at the other areas (Figure 8(g)).

case_images: A 26-year-old male patient presented with the chief complaint of generalized pus discharge from gums which he had been experiencing intermittently for the past 2 years (Figures 9(a) and 9(b)).

case_images: A full mouth periodontal examination revealed generalized deep periodontal pockets and severe generalized clinical attachment loss (Figure 10).

case_images:  OPG and IOPA X-rays revealed a generalized distribution of periodontal bone loss especially severe in the incisor and canine regions with the molars and premolars affected to a lesser degree (Figure 11).
case_images: (a)-(c) Flap surgery in conjunction with bone grafting (HAP) and papilla preservation flap between 11 and 21. (d)-(f) Deep circumferential defect treated with bone grafting in conjunction with guided tissue regeneration.

case_images: In addition, the defect at site 33 was treated with guided tissue regeneration (GTR) with bioresorbable collagen membrane in conjunction with synthetic bone graft (HAP) (Figures 12(a)-12(f)).
case_images: (a) and (b) Postoperative photographs showing probing depths within normal limits with excellent gingival condition; however, there was slight increase in recession after healing. (c) and (d) Comparison of preoperative and 1 year postoperative radiographs shows good bone fill at the defect in relation to 33.

case_images: Postoperative clinical evaluation showed excellent gingival condition with reduction in probing depths to normal levels (Figures 13(a) and 13(b)). Radiographs showed bone fill in the region where bone grafts alone or in conjunction with GTR were used (Figures 13(c) and 13(d)).
