The goal of this clinical trial is to learn if the combined bilaminar tunnel technique works to treat anatomically difficult gingival recessions. It will also explore whether anatomical factors are associated with root coverage outcomes. The main questions it aims to answer are: Does the combined bilaminar tunnel technique improve root coverage outcomes in patients with anatomically difficult gingival recessions? Are specific anatomical factors associated with root coverage outcomes after the combined bilaminar tunnel technique? Participants will: Receive root coverage surgery using the combined bilaminar tunnel technique Visit the clinic for follow-up evaluations after surgery Receive clinical measurements to assess gingival recession and root coverage outcomes Receive radiographic evaluation to assess anatomical characteristics, if clinically indicated or available
NCT07554625
This randomized controlled clinical trial evaluated volumetric changes at recipient and donor sites following free gingival graft (FGG) surgery, comparing two different palatal donor regions. Forty systemically healthy non-smoking adults aged 20-40 years with Miller Class I gingival recession defects at the mandibular anterior teeth (teeth 31, 32, 41, and 42) were randomly allocated using a sealed envelope method into two groups based on the donor site: (1) the anterior palatal region (from the distal of the canine to the first molar), and (2) the posterior palatal/tuberosity region (between the first molar and the tuberosity). All grafts were harvested targeting a standardized size of 8x10 mm (80 mm²). Digital intraoral scans (3Shape TRIOS 5) were obtained preoperatively and at 1, 3, and 6 months postoperatively. Volumetric changes at both recipient and donor sites were measured using STL-based superimposition in Exocad software. The aim was to compare time-dependent volumetric change patterns at both the recipient and donor sites between the two donor groups.
NCT07550517
This research is being done to find out if the study drug, 177Lu-PSMA-617, given before and during standard of care External Beam Radiation Therapy (EBRT) treatment, with a shorter course of Androgen Deprivation Therapy (ADT) (6 months) is (1) safe and effective compared to standard of care alone, and (2) can reduce the side effects caused by long-term (24 months) ADT in men with high risk localized prostate cancer.
NCT03675334
Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (CM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The CM has the advantage of no need of a second surgical area and availability overcoming the limitations of donor site in autograft. The aim of this study is to investigate the use of Mucoderm® in root coverage procedures combined with extended coronally positioned flap (ECAF), test group (TG), in comparison to the connective tissue graft associated with the ECAF, control group (CG).
NCT06438094
The goal of this prospective cohort study is to evaluate the effect of non-carious cervical lesions (NCCLs) on the outcome of root coverage therapy. The main question it aims to answer is: In gingival recessions associated with NCCLs, characterized by an undetectable cemento-enamel junction (CEJ), reconstruction of the CEJ with a cervical composite restoration, prior to root coverage surgery by means of a coronally advanced flap combined with a connective tissue graft (CAF+CTG), provides similar clinical and patient-reported outcomes, as compared to the treatment of gingival recessions associated with NCCLs, characterized by a visible CEJ, with root coverage surgery only, by means of a CAF+CTG. In NCCLs where the CEJ is undetectable (B-type defect), the CEJ will be reconstructed before surgery with a cervical composite restoration mimicking the anatomic features of the contralateral, homologous tooth. CAF+CTG treatment will be performed in all cases. Participants will be assessed at 6 weeks, 3 months, and 6 months to evaluate clinical, volumetric, and patient-centred outcomes.
NCT03162016
Limitation of donor site and significant postoperative morbidity are often described in connective tissue graft harvesting. We want to show if mucoderm used in tunnel technique to recover miller class I and II recessions defects could be an alternative to connective tissue graft.
NCT07467096
The present study will be conducted as a randomized controlled clinical study to assess to evaluate the effect of minimally invasive VISTA with fascia lata allograft in the treatment of gingival recession
NCT07403006
This study aims to evaluate whether the method of root surface preparation influences surgical outcomes. It will assess whether manual root instrumentation can be replaced by a less invasive erythritol air-polishing technique.
NCT07450599
Researchers are looking for a better way to treat men who have high-risk localized prostate cancer, which refers to a type of prostate cancer that is still confined to the prostate gland but has certain characteristics that make it more likely to grow and spread. The study treatment darolutamide plus androgen deprivation therapy (ADT) is under development as treatment before surgery for men who have high-risk localized prostate cancer. Darolutamide works by blocking the attachment of androgen hormones to androgen receptors in cancer cells, thereby blocking cancer progression and growth. ADT is an established treatment that is used to lower the amount of androgen hormones (e.g., testosterone) in the body. The main purpose of this study is to learn how the cancer responds to the two different treatment durations (12 weeks or 24 weeks) of darolutamide combined with ADT used before the men undergo surgery to remove the prostate. For this, the researchers will compare the percentage of participants who either achieve complete response to the treatment (where no cancer cells are found) or with condition of minimal residual disease after the treatment (where only a small amount of cancer cells remains). The study participants will be randomly (by chance) assigned to one of two treatment groups. Depending on the group, they will receive darolutamide tablets by mouth plus ADT administered under the skin for either 12 weeks or 24 weeks. No more than 30 days after the end of the treatments, study participants will be performed with surgery to remove the prostate. Each participant will be in the study for approximately 29 to 32 months, including a screening phase of up to 28 days, 12 weeks or 24 weeks of treatment depending on the treatment groups, followed by the surgery no more than 30 days after the treatment, and a follow up phase of up to 2 years after the surgery. 2 visits to the study site are planned during the screening phase, followed by 3 to 6 visits (every 28 days) during treatment. The treatment period ends with a visit within 7 days after the last dose of treatment. During the study, the doctors and their study team will: * take blood and urine samples * check the participants' health parameters * do physical examinations * check if the participants' cancer has grown and/or spread using CT (computed tomography) or MRI (magnetic resonance imaging) and, if needed, bone scan * take tumor samples * ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments. About 30 days after the last dose of treatment, 5 weeks after the surgery and every 12 weeks thereafter, the study doctors and their team will check the participants' health and any changes in cancer. This follow-up period ends 2 years after the surgery.
NCT07437417
Periodontal health and preservation of the dentition without tooth loss are important quality of life components and should be safeguarded in order to provide optimal function and esthetics. Optimal treatment of gingiva recessions is likely to allow for more efficient use of healthcare resources and reduced costs long-term. It is evident that the prevalence in gingival recession is high and its consequences on the aging population constitute an important healthcare issue that requires further attention. The standard therapy of gingival recession encompasses a coronally advanced flap or coronally advanced tunnel flap and a connective tissue graft from the palate. Harvesting of the palatal graft involves a second surgical site and increased morbidity for the patients.This project aims to compare the connective tissue graft against a novel volume stable collagen matrix. Patients will be treated according to standard protocols of the Department of Periodontology. In the test group patient will undergo tissue thickening with a collagen matrix and the modified coronally advanced tunnel technique. The control group will undergo the standard protocol using a connective tissue graft from the palate along with the modified coronally advanced tunnel technique. No study specific risks do exist.
NCT05851248
The goal of this clinical trial is to to describe and evaluate an approach, free mucogingival graft (FMG), in periodontal plastic surgery for root coverage (RC) in lower incisor gingival recessions (GR) with mucogingival conditions and deformities (MCD) that might negatively influence the outcomes of conventional RC procedures.
NCT07200258
This randomized clinical trial will compare two surgical methods for treating multiple adjacent gingival recessions (types RT1 and RT2): the Modified Coronally Advanced Tunnel (MCAT) and the Vestibular Incision Subperiosteal Tunnel Access (VISTA). Both methods will use connective tissue grafts (CTG), which are the best way to cover roots. The main objective is to use three-dimensional (3D) digital volumetric analysis to look at how the thickness of soft tissue has changed after six and 12 months. Secondary outcomes include root coverage, esthetic outcomes, gingival health parameters, hypersensitivity, patient satisfaction, and wound healing quality. There will be 44 volunteers, and they will be randomly assigned to one of the two surgical methods. Under the same settings, periodontal specialists in training will undertake the procedures at the Universidad Complutense de Madrid. There will be follow-up evaluations at different times up to 12 months after the procedure. The results of this study will help determine whether remote incisions via the VISTA technique offer improved outcomes compared to the MCAT technique.
NCT07359300
This randomized controlled clinical trial evaluated the effectiveness of butyl-cyanoacrylate tissue adhesive compared with conventional sutures for stabilization of free gingival grafts. Twenty-four patients with insufficient keratinized tissue were randomly assigned to either cyanoacrylate or suture stabilization following free gingival graft surgery. Clinical parameters, graft dimensional changes, patient-reported postoperative discomfort, and operative time were assessed over a 6-month follow-up period.

Comparison of Volume-Stable Collagen Matrix, Platelet-Rich Fibrin, and Subepithelial Connective Tissue Graft in the Treatment of Multiple Adjacent Gingival Recessions: A Parallel-Group, Randomized, Controlled Clinical Trial
NCT03570333
The primary purpose of this protocol is to isolate, investigate and compare the regenerative and differentiation potential of mesenchymal stem cells (MSC's) in the gingival (gum) tissue harvested from two different locations from the roof of the mouth (palate), that is from the front part(premolar)and back part(molar). MSC's are known for their capacity to form different kinds of hard and soft tissue including bone, fibers for periodontal ligaments, cementum and dentin, thus this study can help in optimizing their clinical application and transplantation approaches in tissue regeneration.
NCT07292961
This study aims to investigate the effectiveness of BETY, an exercise approach based on the biopsychosocial model, in children and adults diagnosed with scleroderma.
NCT05844254
Management of GR in the initial stages (when there is no inter proximal attachment and bone loss involved) has better clinical outcomes and reduces the chances of further progression of recession. Surgical treatment of recession involves techniques like pedicle grafts and free soft tissue grafts and their modifications. Sub epithelial connective tissue graft is considered as the gold standard in root coverage techniques. However this procedure involves a second surgical site increasing surgical time, complexity and patient morbidity. So there is a need of a technique which overcomes these limitations, is easier to perform and helps to achieve comparable root coverage with stable results over a long term. Novel overlapping rotated double (NORD) flap is a novel technique which offers a solution to this problem. This may help to achieve greater thickness of gingiva in the region of GR after healing and may reduce the risk of future recession. This technique is being compared with the bilaminar technique utilizing the sub epithelial connective tissue graft at the control sites, both the test and control groups will be treated using a microsurgical approach. If there is no significant difference in the root coverage achieved between the two techniques, this may reduce the need of harvesting connective tissue graft from a second surgical site. This technique is also expected to have better patient reported outcomes and will benefit the patients and operator both. This technique may also help to modify the phenotype of the affected tooth, thus making the results more stable.
NCT03124329
Rationale: Treatment of gingival recession defects requires coronal advancement of the gingival margin due to patient esthetic demand, tooth sensitivity and improvement of tooth prognosis, which can be accomplished either through a flap procedure or through a tunnel. It will be desirable to determine the efficacy of Vestibular Incision Subperiosteal Tunnel Access (VISTA) to Coronally Advanced Flap (CAF) procedure and intrasulcular tunneling. Another aspect of the study is to determine whether autologous concentrate of platelets and leukocytes (leukocyte-platelet-rich fibrin; L-PRF) has equivalent efficacy to connective tissue autologous graft harvested from the palate. The overall objective of this study is to evaluate the effectiveness of therapeutic modalities for the treatment of multiple gingival recession defects. The study is designed as a prospective, randomized controlled clinical trial. Four groups will be compared: Group 1: Coronally Advanced Flap (CAF) Group 2: VISTA Group 3: Intrasulcular tunneling (IST) Group 4: VISTA + L-PRF Each of the groups will be treated without any graft material in order to examine the efficacy of coronal advancement and periodontal root coverage without the confounding variable of graft material. These techniques don't require any additional graft if there is adequate amount of keratinized gingiva The study population will be patients who present to Advanced Graduate Program in Periodontology at the University of Southern California, USA, and are deemed to require treatment of multiple gingival recession defects. A total sample of 100 participants (23 participants per group) will provide a two sided test of means with 80% power at alpha of 0.05. The calculation was carried out using PASS Version 12 (Hintze, J. (2014). NCSS, LLC. Kaysville, Utah.) The study duration will be 1 year. Follow-up visits after the surgery will occur after 3 days , 7 days and at weeks 3, 6, 12, 24, 36 and 52. These follow up visits consistent with standard of care follow up for gingival recession treatment and there will be no additional costs to the participant. The Primary Outcome variable is complete root coverage; the Secondary Outcome Variables are clinical attachment level (CAL) gain, changes in gingival thickness and volume and the Tertiary Outcomes are aesthetic outcomes, postoperative pain and Patient satisfaction survey
NCT07158541
Multiple techniques can be used for recession coverage. The most common techniques for single recessions are : tunnel technique (T) and coronally advanced flap (CAF) both combined with a palatal graft to provide sufficient gingival thickness. Recently two modifications have been described in literature, namely the tunneled coronally advanced flap and the modified tunnel. MTUN will function as the control group while people treated with the TCAF technique will function as the test group. This randomized controlled trial compares MTUN and TCAF to determine which technique provides better root coverage for receding gums at single recession in the premandible. The main question it aims to answer is: \- What is the average root coverage achieved with each technique in the short and long term? This may be clinically relevant because covering gum recession can reduce tooth sensitivity, improve aesthetics and make oral hygiene easier. Researchers will compare the modified tunnel technique (MTUN = the gum is undermined) with the tunneled coronally advanced flap (TCAF = the gum is undermined, only partially detached and repositioned higher). In both techniques, a small piece of tissue is removed from the palate, which is used to cover the recession. The purpose of the connective tissue graft under the flap/tunnel, is to increase thickness and provide support. Pain associated to the material used to cover the donorsite will be seen as the secondary research question. The site will either be covered by spongostan and multiple stitches or a palatal stent. Participants will: * Undergo surgery (MTUN or TCAF, randomly assigned) to cover recessions * Attend regular check-ups for up to 10 years after surgery * Keep a postoperative journal (recording medication use, pain levels, tooth sensitivity, etc.)

Gingival recession is a common condition and its extent and prevalence increase with age. Majority of patients probably present with localized and shallow gingival recession that need a specific treatment because they are susceptible to further apical displacement of gingival margin. So if gingival recession is detected early, removal of causative factors and non surgical treatments initiated then it can prevent more advanced mucogingival defects. Studies have shown that non surgical periodontal therapy including proper oral hygiene instructions, periodic scaling and root planning obtained successful root coverage in shallow gingival recession. Minimal invasive non surgical periodontal therapy (MINST)uses the delicate instruments and magnifying loupes performing periodontal debridement with more effective calculus and biofilm removal and less soft tissue trauma , maintain the tissue architecture, benefit the healing phase, improve the clinical results and increase visibility. There is no study to evaluate efficacy of MINST versus conventional subgingival instrumentation in the restorative capacity of marginal gingival in RT1 gingival recession , so the present study will be conducted to compare and evaluate the efficacy of minimal invasive non surgical periodontal therapy (MINST) and conventional subgingival instrumentation in the restorative capacity of marginal gingiva involving RT1 gingival recession.
