    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.
