Papillary regeneration aims to fill the black spaces that occur in interproximal surfaces, one of the most complex cosmetic procedures to be performed among periodontal surgeries. Black triangles (spaces because of the darkened aspect of the oral cavity) occur in more than half of the adults. A correct diagnosis should be performed for either the success or improvement of the treatment of papilla loss, as their etiological factors must be eliminated before considering therapies for reconstruction. In addition to act as a barrier to protect the periodontal structures, the papilla plays a critical role in the aesthetics. Therefore, it is very important to respect the papillary integrity during the dental procedures and minimize its disappearance .
