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.
