Reconstruction of Interdental Papilla Using I-PRF: Case Report of a Novel Technique

Objectives The reconstruction of the lost interdental papilla remains one of the most intriguing and least predictable procedures in periodontology. Preservation of the integrity of the papillae is necessary for form, function, and aesthetics. Both surgical and non-surgical techniques are used for the reconstruction of interdental papilla. Platelet concentrates have wide application in dentistry and has shown promising results in most of its applications. Injectable PRF (i-PRF), which is a recent advancement in PRF formulations, is a liquid concentrate having advantages such as presence of higher leucocyte numbers, higher total growth factor release and expression, requirement of less time for preparation, induction of cell proliferation, migration and angiogenesis, higher fibroblast migration, etc. To date, no case or study has been reported to evaluate the efficacy of single application of i-PRF for the reconstruction of lost interdental papilla. Hence, the present case report intends to evaluate the effectiveness of single application of i-PRF for achieving interdental papillary enhancement.Materials & Methods A 36-year-old female reported to the department of periodontology with a chief complaint of spacing between teeth and gum in her upper right front gum region. A single application of i-PRF for achieving interdental papillary enhancement was evaluated.Results The patient was kept under follow-up for 3 months. After 3 months, the healing was found to be satisfactory and complete closure of the black triangle was noticed. The patient did not report of any adverse effect associated with injection of i-PRF. The patient was re-assessed after 6 months, and there was no recurrence observed.
