View clinical trials related to Gingival Recession.
Filter by:Treatment of gingival recession is indicated mainly for esthetic reasons and keratinized tissue augmentation (Zucchelli and Mounssif, 2015). An array of surgical techniques has been proposed by the literature to cover gingival recession defects with well-documented successful outcomes. The selection of one technique over the other depends on many factors. Some of these factors are related to the gingival recession defect itself, others are related to the anatomy of the palatal fibromucosa, or related to the patient variabilities (Zucchelli and De Sanctis, 2000). Controversy exists in the literature regarding the patient morbidity after connective tissue graft harvesting. Inconclusive postulations have been made about the post-operative patient morbidity outcomes and root coverage outcomes when comparing connective tissue graft harvesting in comparison to allograft membranes used for root coverage. The use of connective tissue graft in combination with root coverage techniques remain the gold standard for root coverage procedures. The problem with the connective tissue graft is that harvesting a graft from the palate increases morbidity, needs an extra surgical site which is more traumatic for the patient, depends on the donor tissue which could be limited, increases surgical chair-time and needs increased surgical skills (Cortellini & Pini Prato 2012). The rationale behind the use of amnion membrane is to avoid the morbidity inherent with connective tissue graft harvesting.
The goal of this clinical trial is to evaluate the effectiveness of two different surgical techniques, the Coronally Advanced Flap (CAF) and the Tunnel Technique (TT) with Connective Tissue Grafts (CTG), in treating mandibular gingival recession. This study, focusing on healthy patients with RT1 and RT2 gingival recessions, aims to determine which surgical approach offers better root coverage for mandibular recession defects. Additionally, it seeks to understand the effects of these techniques on aspects such as keratinized tissue gain, vestibular depth, gingival thickness, and patient-reported outcomes. Participants in this trial will undergo one of the two surgical procedures and are expected to attend a total of six assessment visits. Researchers will compare the results from both groups, those treated with CAF and those with TT+CTG, to discern if one method is superior in achieving more effective root coverage, enhanced aesthetic appearance, and reduced discomfort associated with gingival recession.
Palatal-tissue harvesting is a routinely performed procedure in periodontal plastic surgery. Subepithelial connective tissue graft (sCTG) is considered the gold standard in root coverage. However, over the years, several materials have been attempted to accelerate wound healing and to decrease the post-operative patient discomfort and pain, which are considered the most common disadvantages of tissue harvesting from the palate. Reharvesting from the same region could be necessary in some complicated gingical recessions. For this reason, patients may face long treatment times due to recovery periods of the palate between surgeries. Platelet-rich fibrin (PRF) which has 3-dimensional fibrin matrix structure contributes to regeneration of surgical wounds by releasing growth factors for 10-14 days and showing angiogenic properties. In medicine and dentistry, ultrasonography (USG) method can be used to measure tissue thickness, vascularization, elasticity and blood flow. USG, as a non-invasive method, can provide objective data in evaluating the effects of surgical techniques and biomaterials used on soft tissue healing dynamics and tissue perfusion. The investigators hypothesised that leukocyte rich PRF (L-PRF) application to the palatal area after sCTG harvesting could increase palatal tissue thickness and vascularity throughout 3-month follow-up period compared to the controls. Therefore, in this study, the investigators aimed to evaluate the effects of the L-PRF membrane on soft tissue donor site healing after harvesting sCTG in terms of wound healing dynamics using USG method.
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.
The goal of this observational prospective study is to objectively assess the dimensional (volume & linear variance) and clinical changes of vestibular gingival soft tissues upon treatment with laser-aided pouch roll augmentation technique and implant placement over a 12-month follow-up. Twelve patients with 16 mild horizontal ridge deficiencies in different edentulous sites scheduled for implant placement were enrolled. Digital impressions were taken with an intra-oral laser scanner and software and analyzed before (day 0) and 12 months after laser-aided pouch roll augmentation surgery. The digital files were converted to STL format and superimposed to assess peri-implant volumetric and linear dimensional variations in selected regions of interest (ROI) by a 3D analysis software. Operator-assessed clinical periodontal parameters (probing depth PD, bleeding on probing BoP, plaque index PI) were recorded. Patient-reported outcome (pain, discomfort, treatment liking) and aesthetic result were evaluated by administration of appropriate questionnaires.
Regression analysis in a recent systematic review showed significantly greater mRC and CRC values when modifications are done to the TUN procedure to achieve more coronal advancement of the flap, coronal advancement also helps in covering the underlying graft for better recession coverage outcomes (Tavelli et al., 2018), limited data is present on the possible influence of a covered or partially uncovered graft. However, it has been suggested that minimal exposure of the CTG may aid not only in achieving CRC but also a harmonious gingival margin (John et al., 2015; Rasperini et al., 2011).
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.
The overall objective of this project is to evaluate, over a period of 1 year, the outcomes of either conventional free gingival graft (FGG) or mesh-FGG to increase the width of keratinized mucosa (KM) at implant sites.
The primary objective of this randomized clinical trial is to compare the mean root coverage achieved with Coronally Advanced Flap (CAF) + Connective Tissue Graft (CTG) (control) to Gingival Pedicle Split Thickness flap (GPST) + CTG (test) for the treatment of isolated gingival recession defects in mandibular incisors. The secondary objectives are to compare the percentage of complete root coverage and keratinized tissue gain between the two techniques.
The objective of this project is to evaluate short-term and 1-year outcomes of treatment of multiple adjacent gingival recession defects (MAGRD) using the coronally advanced flap (CAF) with either conventional CTG (control group) or meshed CTG (mesh-CTG) (test group).
