ElementPlanned (methods)Found (results)
PopulationAdults (>=18 years) with clinically evident interdental papilla deficiency or reduced papilla fill without interdental attachment lossAdults with Nordland and Tarnow Class I/II papilla deficiency (n=8 to 24 patients; 30 to 84 papillae per trial)
InterventionInjectable hyaluronic acid, alone or as an adjunctInjectable HA gel (Restylane-Lidocaine, Revofil, HyaDENT BG, Qi Sheng) in 2 to 3 sessions (n=3 trials)
ComparisonSurgical (connective tissue graft, tunneling, envelope) or non-surgical (collagen matrix, platelet-rich fibrin, no treatment) interventionsSaline placebo (n=2), albumin-PRF or injectable PRF (n=1)
OutcomesPrimary: surface area of the black triangle or papilla fill; secondary: esthetic satisfaction, soft-tissue thickness/volume, complications, stability, retreatmentSABT, papilla height, patient satisfaction (VAS), fibroblast proliferation in vitro
Study designsRandomized and split-mouth randomized controlled trials3 RCTs (parallel-group and split-mouth)
TimingNot specified3 to 12 months follow-up
