Active clinical trials for "Gingival Recession"

The purpose of this randomized controlled clinical trial (RCT) is to determine the efficacy hyaluronic acid (HA) in combination with the coronally advanced flap (CAF) for the treatment of single gingival recession site. The hypothesis is that HA will result in improved the clinical outcomes and will reduce the pos-operative morbidity

Different surgical techniques have been proposed for root coverage, showing varying results especially in areas of deep recessions. The aim of this study is to evaluate the effectiveness of the newly forming bone technique (NFB)as an alternative treatment for Miller class I or II deep recessions, requiring regeneration of lost periodontal tissues. Sample should be comprised of patients aged 18-45 years, both genders, presenting at least one site with marginal tissue recession >4mm. Patients will be randomly assigned to either one of the groups, based on treatment technique: newly forming bone (NFB) or subepithelial connective tissue graft (SCTG). Clinical examinations will be performed by a single blinded examiner at baseline, 1, 3, 6 and 9 months after surgery. Intra-group analysis will be performed by one way analysis of variance for repeated measures. Inter-group analysis will be performed by unpaired t-test for each of evaluation periods.

The aim of the present study was to compare between nanocrystalline hydroxyapatite and tricalcium phosphate carried on PRP membrane in treatment of Miller's class 1 gingival recession in human.

This study evaluates the clinical and biological effects of leucocyte and platelet-rich fibrin (L-PRF) on intraoral wound healing.

The aim of this study was to evaluate the effect of two different treatment agents used in conjunction with subepithelial connective graft technique on root coverage outcomes in multiple recession defects. Half of patients will receive root treatment with antimicrobial photodynamic therapy and the other half will receive photobiomodulation therapy by laser on surgery site.

The purpose of this multi-center study is to compare the effectiveness of Mucograft versus connective tissue graft in combination with coronal advanced flap for the treatment of Miller class III recessions The connective tissue graft in combination with coronal advanced flap is considered the gold standard for the treatment of gingival recession in terms of percentage of root coverage and complete root coverage. However connective tissue graft harvesting from the palatal mucosa is often associated with increased patient morbidity, prolonged surgical time and is limited supply. To overcome these inconvenients many efforts are made to develop new materials (healing modifiers, barrier membranes and grafts substitutes) Recently a new two-layer , xenogenic collagen matrix (Mucograft: Geistlich Pharma , Wolhusen Switzerland) has been proposed for regenerative therapy involving teeth and implants. The use of this porcine collagen matrix has obtained promising results for treatment of Miller class I and II recession defects (isolated and multiple recession defects) The mayority of root coverage studies in the literature treats Miller class I and II recession defects .Surgical treatment of class III recesión defects is more challenging due to loss of interproximal bone and soft tissues and complete root coverage may not be expected . But some recent studies demonstrate complete root coverage and high percentage of root coverage in class III recessions. Also a new classification system using the level of interproximal attachment level has been proposed to predict the final root coverage outcome. So ,the soft tissue substitutes should be used also in Miller class III recession, and because of that fact, the investigators are conducting this study, to evaluate the effectiveness of Mucograft in Miller class III recessions compared with connective tissue graft.

OrACell has been tested as a barrier in bone regenerative procedures showing promising results in new bone formation after socket preservation, but no data is available on root coverage procedures. Moreover, it has been suggested that keratinized tissue width (KTW) ≥2mm and gingival thickness (GT) ≥1.2 mm at 6 months of the surgical procedures are two important predictors for long term stability of gingival margin Therefore, it was hypothesized that soft tissue thickness and keratinized tissue width may influence the percentage of root coverage. By means of a prospective case series (12 patients in total), the aim is to study the performance of the OrACell dermal matrix in the treatment of multiple and adjacent gingival recessions, determining the amount of complete root coverage obtained at 6 months of follow-up. At the same time, it is intended to evaluate the effect of initial gingival thickness, by means of digital scanning, upon the success of root coverage procedure with OrACell.

This is a split-mouth, randomized, controlled clinical trial that aims to evaluate the clinical efficacy of platelet-rich fibrin (PRF) membranes in conjunction with coronally advanced flap (CAF) in treating maxillary gingival recession defects.

Miller Class I Gingival Recessions (GR) have been treated by using Coronally Advanced Flap (CAF) with Platelet Rich Fibrin membrane (PRF membrane) or Connective Tissue Graft (CTG). The aim of this study was to evaluate the effect of different multiple layers of PRF membranes for the treatment of GR and compare the results with CTG procedure.

Objective: Titanium-prepared platelet-rich fibrin (T-PRF) is activated with titanium, which results in a more mature and aggregated form than PRF. In our previous studies, we established that the fibrin carpet formed with titanium had a firmer network structure, and longer resorption time in the tissue than the fibrin carpet formed with glass. The purpose of this randomized controlled clinical trial is to compare the effects of autogenous T-PRF and CTG. Materials and methods: A total 114 Miller Class I/II gingival recessions with abrasion defects will be treated either T-PRF (63 teeth) or CTG (51 teeth) using a modified tunnel technique. Clinical periodontal indexes, keratinized tissue (KTW), gingival thickness (GT) and recession depth (RD) will be recorded before surgery and at 6 and 12-month follow-up examinations. The Visual Analog Scale and healing index scores will be assessed.
