Reconstructing the interdental papilla- Can we get back the lost pink triangle?



In the modern era, the treatment focus in dentistry has been shifted more on esthetics with an enhanced awareness of beauty. Unlike in the past, when only functional demands were the primary consideration in dental treatment, now esthetic dentistry involves the management and reconstruction of the encasing gingiva.

With recent advances, periodontal plastic surgery aims to correct or eliminate anatomical, developmental, and/or traumatic deformities of the gingiva or alveolar mucosa to preserve and restore periodontal health with improved aesthetic outcomes of the treatment.

One among such problems is open interproximal spaces or the black triangles. “Black triangles” or the interproximal spaces are one of the most troubling dilemmas in dentistry, which can cause aesthetic concerns while smiling, phonetic difficulties, and food impaction. Several reasons contribute to the loss or absence of interdental papilla or loss of “Pink Triangle” and establishment of ’Black Triangle,’ including gingival inflammation, attachment loss, and interproximal bone resorption.

Once the papilla is lost due to any of the above factors, rebuilding it again and expecting regeneration is cumbersome. Surgical reconstruction of the papilla or its augmentation is the most esthetically challenging and technique-sensitive procedure, but it can give lasting and natural results if performed correctly. The surgical techniques aim to recontour, preserve, or reconstruct the soft tissue between two natural teeth or between teeth and implants.

Many techniques have been documented, but we will be discussing the cases of subepithelial connective tissue graft to reconstruct interdental papilla.
