NCT05533528
The objective of this study will be to evaluate a new protocol for the surgical treatment of periodontal disease with two novelties: to make a single incision in the midline of the interproximal area to respect the vascular supply and preserve the granulation tissue with regenerative potential. The investigators will carry out a controlled and randomized clinical trial with a control group (n=25; modified Kirkland flap) and a test group (n=25; experimental surgical protocol: incision in the mid-interproximal area of the papilla and preservation of the granulation tissue). Clinical parameters will be taken at the time of surgery and 12 months follow-up: bleeding on probing (BoP), clinical attachment level (CAL), residual probing depth (rPD),Probing pocket depth reduction (PPDr), recession (REC), interproximal gingival recession (iGR), width of keratinized gingiva (KT), gain of supra-alveolar clinical attachment (SUPRA-AG), early wound healing index (EHI).
NCT07254117
The goal of this observational study is to distinguish the infectious, healing, and regeneration-related characteristics of two types of gingival granulation tissues, namely infra-osseous and supra-osseous granulation tissues, in people with severe periodontitis (gum disease). Researchers aim to denote if these tissues may play role in healing after periodontal treatment. Researchers will also compare smokers and non-smokers to see if smoking disrupts the healing potential or infectious properties of granulation tissue. Participants will provide gingival fluid (before) and granulation tissue samples (at the time of) periodontal surgery. The main questions this study aims to answer are: 1. Do infra- and supra-osseous granulation tissues have different healing potential and infectious properties? 2. How do these tissues differ in people who smoke compared to people who do not smoke?
NCT07230522
The goal of this clinical trial is to learn whether hyaluronic acid (HyaDent® BG) provides similar benefits to Emdogain® when both are used with Bio-Oss® Collagen during periodontal surgery in adults with periodontal (intrabony) defects. The main questions it aims to answer are: Does the treatment reduce probing pocket depth? Does the treatment increase clinical attachment level? Does the treatment increase radiographic bone fill? Does the treatment change the gingival margin position? Researchers will compare Bio-Oss Collagen + HyaDent BG with Bio-Oss Collagen + Emdogain to see whether HyaDent BG achieves similar improvements in clinical and radiographic outcomes as Emdogain. Participants will: Undergo periodontal surgery to treat the vertical bone defect(s), with either Bio-Oss Collagen + HyaDent BG or Bio-Oss Collagen + Emdogain. Attend follow-up visits for periodontal measurements and radiographs.
NCT07183631
Objective: To evaluate clinically the long-term results following treatment of deep intrabony defects with either platelet-rich fibrin gel (PRF) or an enamel matrix derivative (EMD). Methods: Twenty six patients diagnosed with advanced chronic periodontitis, and each of whom displaying one deep intrabony defect were randomly treated with open flap debridement and with either PRF (test) or EMD (Emdogain, Straumann, Basel, Switzerland) (control). The clinical outcomes were evaluated at baseline, at six months and three years after treatment. The primary outcome variable was the clinical attachment level (CAL).
NCT07146776
The use of injectable platelet-rich fibrin (i-PRF) in both surgical and non-surgical dental treatments has become increasingly widespread. Hard tissue grafts can produce "sticky bone," and bone gain can have a positive effect on intrabony defects frequently seen in periodontal disease, compared to grafts alone. This study aims to clinically and radiographically evaluate the effectiveness of using bovine-derived xenogenic bone grafts in combination with i-PRF and bovine-derived xenogeneic bone grafts alone in patients with intrabony defects and stage III periodontitis.
NCT03978962
The evaluation of the clinical data has demonstrated the conformity of the Resorbable Collagen Membrane (RCM), EZ CureTM, with the relevant essential requirements for its use in periodontal applications. The RCM is intended for Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR) procedures. It acts as a barrier against the migration of epithelial cells within the bone defect (performance) and thus complies with several surgical indications in the treatment of maxillofacial bone defects. It has been concluded that the risks associated with the use of this device are acceptable when weighted against the benefits to the patients. In order to improve the clinical data on the RCM, the manufacturer, Biomatlante, decided to assess that the performance and safety of the device are maintained until the reaching of its intended use. In this objective, the goal of this study will be to observe the following parameters: 1. Tissue regeneration (mucosa health on the site of implantation) 2. Safety (report of any adverse event) 3. Radiographic analysis of periodontal tissues
NCT05932017
This study is being performed to compare different methods of visualization during routine gum surgery. The gum surgery is standard of care. This study will compare the use of a small camera (videoscope) in conjunction with magnification glasses during surgery vs. surgery only using magnification glasses. Both methods are routinely used and are standard of care methods of visualization. The small camera (videoscope) is a device which allows us to see the area under high magnification and projects live video feed on a computer screen. The study is a split-mouth design pilot study. The patients are only receiving treatment that was previously diagnosed prior to entering the study. The treatment performed is standard treatment that fits in the routine standard of care. No interventional treatment is being performed. The only difference is the method of visualization/observation by the practitioner used during the surgical procedure. One side of the mouth will be treated with just loupes while the other side of the mouth will be treated with loupes and the videoscope.
NCT05237739
Periodontitis, a microbially-driven inflammatory disease has been shown to be the sixth most common disease of mankind. The 2009 UK Adult Dental Health Survey found that 54% of adults experience gum bleeding (gingivitis) with 45% of these suffering from periodontitis. Periodontitis begins at the gingival margins of teeth and over time, in susceptible individuals, the presence of a plaque biofilm can lead to the loss of the supporting connective tissue and alveolar bone associated with the teeth. This leads to the formation of a pathological periodontal pocket between the gingiva and tooth root, measurable by the use of a periodontal probe and recorded as the probing pocket depth (PPD). The associated loss of alveolar bone support is measurable radiographically and often leads to tooth mobility and if allowed to persist, can eventually lead to tooth loss. Periodontitis is classified into 4 stages (I-IV) based on disease severity and 3 grades (A-B-C) based on risk of disease progression. The treatment of periodontitis involves a non-specific reduction of the bacterial load below the gingival margin. This is achieved by effective oral hygiene procedures and non-surgical periodontal therapy (NSPT), both of which are aimed at the removal of calculus (tartar) deposits and the disruption of the plaque biofilm from the affected root surfaces. In some cases, this treatment may then be followed by more invasive treatments such as periodontal surgery and if successful, patients can then be followed and maintained with supportive periodontal maintenance therapy (SPT). It should be noted that certain periodontal lesions in some patients do not however always respond favourably to treatment.
NCT05631600
The goal of this split-mouth clinical trial is to evaluate the effects of Manuka honey applied into periodontal pockets after initial periodontal therapy (NSPT) in the treatment of stage 3 periodontitis. The main question it aims to answer is: • does the adjunct of Manuka honey improve the outcome of the non-surgical periodontal treatment. The intervention in this study was conducted in a split-mouth design, meaning that after completing the NSPT for each subject, Manuka honey was administered as an adjunct to the periodontal treatment in two randomly selected quadrants of the oral cavity around the teeth with a specially designed cannula. This was followed by oral hygiene instructions and training. The home-performed oral hygiene procedures were focused on interdental cleaning using dental floss and toothbrushing with regular fluoride-containing toothpaste. The subjects were also instructed not to use any form of oral antiseptic (e.g., chlorhexidine) or antibiotic during the follow-up period.
NCT05496608
For patients having periodontal intrabony lesions, three treatment modalities were executed to evaluate the effect of protecting Leukocyte rich -Platelet Rich Fibrin harvests (applied in the bony defects) with resorbable collagen membranes. Clinical Outcomes recorded were the Plaque index (PI), Gingival index (GI), probing depth reduction (PD), Clinical attachment level (CAL), and radiographic defect depth changes. For the biochemical evaluation: levels of PDGF-BB and VEGF obtained from crevicular fluid by Perio-Paper strips were assessed using ELIZA.
NCT03715374
The primary outcome of periodontal reconstructive therapy is to regenerate all tissues of the periodontium including a functional periodontal ligament, alveolar bone and cementum. A number of treatment modalities including the use of bone grafts, guided tissue regeneration (GTR), and the addition of biological agents have been used with large heterogeneity in the clinical and histological outcomes. The rationale of using a filling material when treating unfavorable and large intrabony defects (IBDs) with membranes or biological agents consists of sustaining the overlying soft tissues in the presence of a non-contained defect's architecture, at the same time enhancing the stability of coagulum; and facilitating the proliferation of mesenchymal progenitor cells. Among bone grafts available, anorganic bone bone (ABB) have been widely used in periodontics for the treatment of IBDs In recent years, the increasing understanding of the role of growth factors (GFs) in the wound healing process suggested the use of these biological agents in the regenerative treatment of periodontal bony defects. Noninferiority trials are designed to demonstrate that the effect of a new treatment is adequately similar to an active control by more than a specified margin The aim of this study is to verify if the combined use of PRF (Platelet Rich Fibrin) and ABB in the management of IBDs may be a treatment modality that is clinically "not inferior" compared to the membrane + ABB one, since the combined periodontal regenerative technique has been already tested in literature as a "gold standard" periodontal regenerative technique.

NCT03227367
The present study is an effort to investigate the hypothesis that Platelet Rich Fibrin/Biphasic Calcium Phosphate may play a role in inhibiting osteoclasts differentiation and in bone loss.
NCT02218515
The present study aimed to evaluate the effects of enamel matrix derivatives either alone or combined with autogenous bone graft applied to intrabony defects in chronic periodontitis patients on clinical/radiographic parameters and gingival crevicular fluid transforming growth factor-β1 level and, to compare with open flap debridement. Our hypothesis is to test whether the use of autogenous bone graft and enamel matrix derivative combination in the treatment of intrabony periodontal defects enhance the clinical, radiographic and biochemical parameters in comparison to the use of open flap debridement alone.
