Minimally invasive pouch technique with leukocyte platelet rich fibrin compared to non-invasive hyaluronic acid injection in reconstruction of interdental papilla in esthetic zone: a randomized clinical trial.
Trial report in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05953896 (Efficacy of Hyaluronic Acid Gel Injection Versus Multilayer Leukocyte Platelet Rich Fibrin), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundInterdental papilla deficiency is of high concern from the esthetic and functional perspectives. Several invasive approaches have been reported for interdental papilla reconstruction. However, the long-term success of invasive approaches is still controversial, therefore this study aimed to assess the minimally invasive Pouch technique using Leukocyte Platelet Rich Fibrin compared to non-invasive Hyaluronic acid gel injection in the reconstruction of Interdental papilla in esthetic zone.
methodsThe study was designed as a randomized, controlled, double-blinded, and phase (IV) clinical trial. The trial was registered retrospectively with the date (21/7/2023) and registration number (NCT05953896). A total sample size of 20 cases was planned to be recruited. i.e. (10 patients in each group). Patients with deficient interdental papilla class I or II in the esthetic zone were selected, then patients were randomized using computer-generated block randomization into two equal groups: group A (L-PRF) and group B (HA gel). Blinding was performed in selection of patient intervention, while blinding of the intervention wasn't applicable since both interventions are completely different. The clinical and radiographic parameters were assessed at 3 and 6 months, As well as evaluation of patient satisfaction between the two tested groups.
resultsBoth groups showed significant improvement in all clinical parameters at 3 months and 6 months postoperatively. Assessment of patient satisfaction showed overall improvement in both groups after 6 months, with successful reduction in the mean value of black triangle height of the PRF group: (0.9 ± 0.52), and HA group: (0.6 ± 0.46), with no significant difference (P value: 0.178
conclusionsBoth injectable HA and multilayered L-PRF gave successful results that can be comparable to the invasive surgical techniques.
