Interdental papilla construction, especially in the esthetic area, is one of the most challenging tasks. Interdental papilla loss might occur due to several reasons as a consequence of periodontal surgery or trauma. The purpose of this study is to report the reconstruction of lost interdental papilla using hyaluronic acid gel. Hyaluronic acid is a glycosaminoglycan molecule with anti-inflammatory, anti-edematous properties on periodontal tissues invaded by submicrobial flora. It enhances wound healing and accelerates periodontal repair and regeneration. In addition to the field of dentistry, it has been used in other fields such as orthopedics, ophthalmology, and dermatology. It shows growth factor interaction, regulates osmotic pressure, and enhances tissue lubrication, which helps in maintaining the structural and homeostatic integrity of tissues, hence resulting in beneficial effect on lost interdental papilla. This study was aimed to reconstruct the lost interdental papilla by injecting 0.2% hyaluronic acid via nonsurgical approach. It is a noninvasive approach which reduces patient's postoperative discomfort with marked variations in the volume of interdental papilla before and after the procedure. As sufficient information is not available regarding the effectiveness of hyaluronic acid in interdental papilla construction, this study was conducted.

Periodontal regeneration is the major focus for treatment of periodontitis. The goal of periodontal therapy is to regenerate the periodontal tissues destroyed by the disease process. Present study was carried out to investigate the efficacy of guided tissue regeneration (GTR) membrane in the treatment of deep infrabony defects. A patient with pain and pus discharge in maxillary second molar was presented with pocket probing depth of 8mm and was treated with DFDB allograft covered with GTR membrane and was sutured. It was found that after 6 months of surgical procedure of GTR membrane placement with decalcified freeze dried bone allograft, a reduction of 5mm in pocket probing depth took place, which indicates that the resorbable GTR membrane can be effectively used for the treatment of deep infrabony angular defects.

Gingival recession is the most common mucogingival deformity and should be treated at its earliest detection. Exposed root surfaces are more likely to develop root sensitivity and root caries and pose esthetic problems. Among various procedures, laterally positioned pedicle graft (LPG) is widely used successfully to cover Miller class-I and Class-II recession defects. The main advantages of the laterally positioned pedicle graft are that it is relatively easy and less time-consuming. It produces excellent esthetic results and no second surgical site is involved for donor harvesting. Thus the present study was undertaken to understand the efficacy of lateral pedicle grafts in Miller's class I gingival recession defects.
