Microneedling-Assisted Hyaluronic Acid for Interdental Papilla Deficiency
Microneedling-Assisted Hyaluronic Acid for Interdental Papilla Deficiency: Effects on Gingival Crevicular Fluid Biomarkers and Clinical Outcomes-A Randomized Controlled Clinical Trial
This randomized controlled clinical trial will evaluate whether microneedling combined with cross-linked hyaluronic acid injection provides superior reconstruction of interdental papilla deficiency compared with hyaluronic acid injection alone. Twenty participants with Nordland-Tarnow Class I or II interdental papilla deficiency will be randomly allocated into two parallel groups. The test group will receive microneedling followed by submucosal injection of cross-linked hyaluronic acid, while the control group will receive cross-linked hyaluronic acid injection alone. Three treatment sessions will be performed at 4-week intervals. Participants will be followed for 6 months. The primary outcome will be change in black triangle height. Secondary outcomes will include gingival crevicular fluid levels of MMP-9, TIMP-1 and periostin, plaque index, gingival index, periodontal probing depth, and patient satisfaction.

실험적: Microneedling + Hyaluronic Acid (MN+HA)
Participants will receive microneedling of the interdental papilla followed by submucosal injection of cross-linked hyaluronic acid. Three treatment sessions will be performed at 4-week intervals. |
A sterile disposable microneedling device will be applied to the interdental papilla using controlled vertical and oblique strokes until uniform punctate bleeding is observed. Cross-linked hyaluronic acid will be administered by submucosal injection into the interdental papilla. Three treatment sessions will be performed at 4-week intervals. |

활성 비교기: Hyaluronic Acid (HA)
Participants will receive submucosal injection of cross-linked hyaluronic acid without preceding microneedling. Three treatment sessions will be performed at 4-week intervals. |

|
Change in Black Triangle Height
기간: Baseline, 1 month, 3 months, and 6 months
|
Black triangle height will be measured in millimeters as the linear distance from the base of the interproximal contact point to the most coronal tip of the interdental papilla using a calibrated UNC-15 periodontal probe. Standardized acrylic stents will be used to ensure reproducible probe angulation and reference point positioning. |
