Restoring defective interdental papilla partially or totally in structure and function creates a challenge in dental field owing to the small working space and limited blood supply to the area. This led to the innovation of different techniques for treatment of defective interdental papilla that aimed at papillary tissue augmentation reported to be attained through influencing connective tissue cell proliferation, providing clot stability, protecting the reconstructed site during wound healing. Among these techniques is the injection of hyaluronic acid gel have been considered of the latest non-invasive technique to escape drawbacks of surgeries. Though proved to have some positive results in the literature however still entails unpredicted complete gingival papilla improvement because of the diverse injection methods, cycles, dosage, and the course of treatment that needs further optimization, in addition to the lack of unified patient inclusion criteria, especially the gingival biotype . Several surgical techniques designed to host the richest effective known sub-epithelial connective tissue graft had failed to allow maximum benefit of the graft due to the disadvantages from the number and location of incisions of their flap design, which possibly disrupt the blood supply needed added to unconsidered flap thickness, and flap retraction that impacted the success of soft tissue grafting. Surgical Tube technique has recently been developed optimizing flap thickness, flap retraction and tension to escape disturbance of the blood supply of the graft by its use of apical incisions and containment of the graft within a rich vascular enclosed bed, thereby offering an attempt to guarantee integrity of soft tissue with no disruption of blood supply.
