Brief Summary
The interdental papilla is a crucial part of an esthetic smile, its loss results in gingival black triangles giving unpleasant appearance which directly affect patient self-esteem (Lee et al. 2016). The presence of interdental papilla is of great concern for the clinician and the patient. Gingival black triangles are considered to be the most disliked esthetic issue. As well open embrasures can cause food impaction and phonetic problems (Prato et al. 2004). The treatment of black triangles is challenging in modern dentistry. The treatment options are surgical and non-surgical. Surgical treatments are invasive and do not always give a predictable result due to limited blood supply of the papilla (Mansouri 2013). However, no technique has been set up as a gold standard treatment for gingival black triangles, although, connective tissue graft surgical techniques are the most common used approaches for treatment of black triangles (RahimiRad 2018). A modern, non-surgical method for treating papillary deficiencies is the use of hyaluronic acid, which have demonstrated encouraging outcome (Ni et al. 2021). Subperiosteal hyaluronic acid injection overlay technique was proposed by Spano et al, (2020) with the idea of merging hyaluronic acid injection with simple surgical intervention to reconstruct the lost interdental papilla. As far as we know, there is no present studies comparing hyaluronic acid overlay technique with connective tissue graft in treatment of interdental papilla deficiencies.

Outcome Measures
Primary Outcomes (1)
Changes in papilla height
Clinical changes in papilla will be recorded by measuring papilla height at the distance between the tip of the papilla and the incisal edge of the adjacent tooth using UNC periodontal probe .
Changes will be recorded at 3, 6 and 12 months
Secondary Outcomes (7)
Percentage of changes in papilla height
3, 6 and 12 months
Papilla presence index
3, 6 and 12 months
Clinical attachment loss
3, 6 and 12 months
Gingival thickness
3, 6 and 12 months
Post-operative pain
1,3 and 10 days post-surgical.

ACTIVE COMPARATORInterventions
using subperiosteal hyaluronic acid injection overlay technique showed promising results in treating lost interdental papilla which needs further assessment to its clinical effectiveness
Connective tissue graft base techniques have been for years the most predictable approach for treatment of interdental papillary defects. CTG can as a biological filler which enhances flap stability and wound strength. CTG also can promote coagulation cascade and protects the maturating fibrin clot (Tavelli et al. 2019). Moreover, CTG results in significant increase in gingival tissue thickness which positively improve tissue fill and soft tissue volume creeping which influence esthetic outcomes following periodontal regeneration
