Active clinical trials for "Gingival Recession"

Gingival recession is the term used to describe the apical positioning of the marginal gingiva from the enamel-cementum junction. Platelet-rich fibrin (PRF) has been routinely used for more than 20 years to increase keratinized gingival thickness and to close gingival recessions due to the growth factors it contains. In the literature, there are studies evaluating the application of i-PRF with the microneedling technique, but there is no study evaluating the creeping attachment phenomenon and the closure percentage of gingival recession with the creeping attachment after the application of this technique. The aim of this study is to evaluate the closure rates of gingival recession and creeping attachment phenomenon after i-PRF application with microneedling technique. Systemically healthy and non-smoker patients older than 18 years of age with gingival recession in mandibular anterior teeth and keratinized gingival deficiency will be included. Before the procedure, the venous blood taken from the patient will be centrifuged at 700 RPM for 3 minutes in glass and non-addition tubes to obtain i-PRF. The prepared i-PRF will be infected to the apical mucogingival junction of the keratinized gingival area. This process will be repeated once a month for 3 months. After the 3rd month, the horizontal and vertical gingival recession values will be evaluated and recorded at the end of 6 months and 1 year.

The purpose of this study is to examine the relationship between placing specific retraction cord for different periods of time and the post-operative gingival margin level in humans. Determining the amount of immediate reversible and delayed irreversible gingival recession (vertical gingival retraction) that might happen after placing a retraction cord around a natural tooth in healthy humans. It also aims to investigate the impact of mechanical and chemo-mechanical gingival retraction on periodontal health.

The present study aims to assess the effectiveness of three different retention schemes used to maintain tooth position after orthodontic treatment with fixed orthodontic appliances (stability) and to evaluate possible association between retention scheme and gingival recessions on the lingual surfaces of the lower anterior teeth seen for up to 5 years post-treatment. Moreover the possible association between primary relapse tendency and long term occlusal stability will be evaluated.

The goal of this clinical trial is to compare two different tunneling surgical technique in treatment of gingival recession using two different materials. Participants will be divided into four groups according to the treatments they'll be given.

This study is proposing the use of i-PRF clot as a scaffold for the XCM in order to obtain a novel biomaterial, incorporating active growth factors and collagen matrix in a single framework, based on the potential effect of i-PRF to enhance fibroblast activity and angiogenesis stimulation for treatment of multiple gingival recession.

The aim of this study is to evaluate the effect of retraction techniques on gingival health. Four different method (212 clamp (Hu-Friedy, USA); Brinker B4 clamp (Coltene Hygenic, USA); dental floss using the simple knot tie method; and using the simple knot tie and 212 clamp together) will evaluated. After rubber dam isolation restorations will be performed, each restoration will take maximum 30 minutes. Changes in periodontal tissues will be evaluate; using plaque index, bleeding on probing, probing depth, keratinized gingiva, attached gingiva, relative gingival margin level, relative attachment level and VAS (visual analogue scale) scoring and patient comfort levels after the procedure at different times (pre-restoration, after restoration, 1 week, 1 month, 3 month). The evaluation time is planned not to exceed 10 minutes, restorations are done by a single specialist in Marmara University Restorative Dentistry Department.

The aim of the present randomized controlled clinical study is to compare the efficacy of subepithelial connective tissue graft harvested from the palatine area or from the maxillary retromolar tubeosity area in the treatment of RT1 recessions by coronally advanced flap. A total of 42 patients will be recruited and randomly assigned to the test group treated with CAF+tSCTG or the control group treated with (CAF+pSCTG). For each experimental site the parameters of gingival recession (GR), pocket depth (PD), clinical attachment level (CAL), keratinized gingiva width (KT) and gingival thickness (GT) will be analyzed at baseline (T0) and at 3 months after the surgical procedure (T1). In addition, the different morbidity of the two surgical techniques was also evaluated using the VAS scale values recorded in the first 2 weeks following surgery.

The aim of this randomized, parallel-group clinical trial was to compare the 1-year periodontal, root coverage, esthetic, and patient-centered outcomes of the partial restoration placement with different apical margin levels combined with coronally advanced flap (CAF) plus connective tissue graft (CTG) in the treatment of isolated gingival recessions associated with non-carious cervical lesions (NCCL). Forty patients with single gingival recessions (RT1 gingival recessions and class B+ NCCL) were randomly allocated to either placement of restoration apical margin at the level of estimated cementoenamel junction (CEJ) or within 1 mm apical to the CEJ. Two weeks after the restorative treatment, all recession defects were treated with CAF combined with CTG. Periodontal measurements were taken at baseline, and 3, 6, and 12 months postoperatively. Patient-centered outcomes were evaluated at baseline, and 7, and 15 days, 6, and 12 months postoperative follow-ups. Modified root closure aesthetic score (mRES) was used to assess aesthetics at 6 and 12 months follow-ups.

This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva. To the investigators knowledge, these two techniques have not been compared for differences in clinical (amount of root coverage, tissue thickness, and esthetics) and patient-centered outcomes (pain, swelling, change in daily activities) in a controlled study.

The study aims to test the non-inferiority of an Allogenic Dermal Matrix with Platelet-Rich Fibrin for treatment of gingival recessions in comparison to the Connective Tissue Graft.
