Abstract
The absence of interdental papillae leads to the appearance of black triangles. For most patients, the appearance of these triangles is an important reason for concern and affects their social relationships. Multiple reconstruction techniques have been developed with different degrees of success and predictability. The main aim of this study was to evaluate the efficiency of hyaluronic acid (HA) injected into interproximal papillae 6 months after injection and to perform a systematic review and meta-analysis. After a systematic review, seven articles were selected: two clinical randomised controlled trials and five clinical trials. In total, 127 patients with a deficiency in upper papillae in the front of the maxilla and jaw were included in the study. The height variable was evaluated (mm) 6 months after HA injection. In total, 166 interproximal papillae were studied. Four articles showed an important difference in favour of intervention. The total result regarding in the injection of HA was favourable with an approximate average filling of 0.47 mm in the height of the interdental papilla. The injection of HA for the reconstruction of deficient papillae in the region of the upper and lower maxilla was a possible option treatment strategy in mild black triangles.
Highlights
The interdental papilla is a soft tissue found in the cervical area of the free gingiva, extending from the interproximal alveolar crest to the point of contact [1].The loss of the interproximal papilla has both functional and aesthetic effects, which have been the subject of numerous studies [2,3,4].The cause of the loss of the papilla is multi-factorial; the loss of the papilla results in the appearance of so-called “black triangles”.Reconstruction of the interdental papilla has been approached from various techniques
The hyaluronic acid (HA) injection technique is effective for the reconstruction of interproximal papilla defects within 6 months of injection
The main limitation of the technique is the maximum increase in papilla that can be achieved

The interdental papilla is a soft tissue found in the cervical area of the free gingiva, extending from the interproximal alveolar crest to the point of contact [1]. The loss of the interproximal papilla has both functional and aesthetic effects, which have been the subject of numerous studies [2,3,4]. Reconstruction of the interdental papilla has been approached from various techniques. Most of them include surgical techniques with not always predictable results. The minimally invasive HA approach has the potential advantage of being effective, predictable, and minimally invasive with only slight injury [5]. Most efforts have focused on conservation techniques with the main limiting factor being the delicate vascularity of the papilla [6,7,8]
