Active clinical trials for "Periodontal Pocket"

The purpose of this study is to compare the clinical and radiographic effectiveness of Leukocyte-Platelet Rich Fibrin (L-PRF) and L-PRF combined with dental pulp stem cell (DPSC) application to the extraction socket of mandibular third molars.

Rheumatoid arthritis and periodontitis are two inflammatory diseases that share many pathophysiological similarities as some inflammatory mediators like TNF-alpha, IL-1, Il-6, Il-17, Il-12 et Il-17, RANK-L, or OPG The most severe or progressive forms of rheumatoid arthritis require in 10-30% of cases, the use of biotherapies such as anti-TNF-alpha, anti CD-20 and anti-lL-6. All these treatments results in, among other things, an increased risk of infection, both viral and bacterial. These new biotherapies could have an impact on periodontal status either by favouring sub gingival colonization of root surfaces by periodontal pathogenic bacteria and initiate periodontitis or exacerbate pre-existing periodontitis, or a positive modulation of the host response by inhibiting bone resorption of the alveolar process. To date, very few studies have been conducted on this subject which is really a translational research, involving several medical specialties.

A Randomized, controlled clinical trial and split-mouth design was performed to assess and compare the effect of platelet-rich fibrin (PRF) on soft tissue healing, periodontal pocket depth and alveolar bone height distal to second molar of the study and control groups after third molar surgical removal. Sample include of participants who had indication of impacted lower third molars extraction on both sides with symmetrically orientation and same difficult index. All participants had same extraction protocol on both side at Department of Oral surgery, Faculty of Odonto-stomatology, University of Medicine and Pharmacy, Ho Chi Minh City. Soft tissue healing, periodontal pocket depth and distal bone height were evaluation by an independent investigator.

Chronic periodontitis is an inflammatory and polymicrobic disease characterized by the irreversible loss of alveolar bone and connective tissue attachment of the teeth. Chronic periodontitis is the most prevalent type of periodontitis and it is seen in the great majority of the adult population. The main objective of periodontal treatment is to heal the inflammatory tissue, to eliminate unhealthy periodontal pockets, and to reduce the number of pathogenic bacteria. The traditional treatment of chronic periodontitis is debridement performed with hand tools and ultrasonic devices. However, in deep pockets, which are difficult to access, mechanical root surface debridement is not sufficient to remove the biofilm via root instrumentation. The regeneration of the periodontium aims at the reconstitution of the periodontal ligament, alveolar bone, and cementum. Platelet concentrates have gained popularity in regenerative periodontal therapy due to their autologous nature. Their regenerative potential is associated with growth factors such as TGFβ-1, PDGF, EGF, IGF-I, and VEGF, stimulate cell proliferation and regulate matrix remodeling and angiogenesis. Growth factors are naturally occurring proteins that regulate cell growth and development. They also modulate cell proliferation, migration, extracellular matrix formation and other cellular functions in epithelization. In addition, some growth factors may function as cell differentiation factors. These functions of the growth factors support epithelization following surgical periodontal treatment and reduce postoperative pain and swelling with their anti-inflammatory properties. Furthermore, studies have reported their antibacterial potentials. Different platelet concentrates such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are obtained when whole blood is centrifuged at different speeds and for different durations. When the literature is reviewed, it is seen that these platelet concentrates are frequently used in regenerative therapies in dentistry. In 2010, Sohn et al. obtained autologous fibrin glue (AFG), an injectable platelet concentrate, by centrifuging venous blood for two minutes in a special centrifuge device (Medifuge, Silfradent, Italy; 2400-2700 rpm). AFG is used, by mixing it with bone grafts, in the production of sticky bone, which could be an alternative to titanium mesh and bone block procedures that enable grafts to remain more stable in defects. It was found in the literature review that studies on AFG, which is a second-generation platelet concentrate, are limited in number. It was also found that these studies were conducted on sticky bone, obtained by mixing AFG with bone grafts, and there are no studies in which AFG is used alone to treat periodontal diseases. The purpose of this study is to investigate the effect of AFG, an injectable platelet concentration, on clinical parameters in the nonsurgical treatment of chronic periodontitis.

The purpose of this study was to demonstrate in patients with generalized chronic periodontitis that switching from cigarette smoking to using IQOS improves the response to periodontal therapy and the overall oral health status compared to continuing cigarette smoking. Note: "IQOS" is the Tobacco Heating System (THS) with Marlboro Heatsticks, marketed in Japan under the brand name IQOS

This is a controlled, randomized, single-blinded, multicenter, prospective clinical study. In addition to the standard periodontal treatment procedure on all teeth that need to be treated, the 4 teeth with the deepest pockets (between 4 and 6 mm) will be randomized to either PERIOSYAL® FILL and oral hygiene or oral hygiene alone. The pocket depth will be measured at six sites around each tooth, and only the deepest pocket sites of each tooth will be taken into account.

Periodontal diseases are among the most common medical conditions that may influence humans; 50% of the adult population can be affected by this illness. The condition is usually initiated by lack or reduction in oral hygiene which is then aggravated by the presence of microorganisms within biofilm which will induce a sequel of events that will lead to periodontitis. Scaling, root planning, and polishing (SRP) are the golden standard procedures in the treatment. Systemic antibiotics as adjunctive therapy has been established to be an excellent modality in controlling the bacterial virulence, hence, supporting the conventional SRP therapy. in order to avoid and limit the harmful effect of systemic antibiotics different locally applied preparations have been introduced including antioxidants. The aim of this prospective clinical study is to compare between the effect of Minocycline hydrochloride (HCL) microsphere and Lycopene gel when they are applied intrapocket subgingival with conventional SRP therapy

Assessment of the efficacy of BMG0703 in the treatment of periodontitis and control of supragingival plaque, compared to Chlorhexidine and a placebo product

Periodontal disease is a chronic inflammatory disease of the tissues surrounding the teeth and is one of the leading causes of tooth loss. Sanative therapy (ST) is a non-surgical procedure that allows for removal of bacteria from the deep pockets that form around teeth and is the frontline treatment for periodontal disease. Post-ST, patients require ongoing maintenance appointments to maintain their oral health, though whether risk factors for periodontal disease remain a predictor of periodontal health post-ST has not been comprehensively investigated. Risk factors to be examined include physical activity, exercise, sedentary time, flavonoid intake, protein intake, BMI, sex, age, smoking status, and number of sites with periodontal probing depth (PPD) ≥ 4mm at baseline.

The purpose of this clinical trial is to both clarify the efficiency of autologous periodontal ligament (PDL) stem cells to regenerate periodontal tissue in periodontitis patients with deep intraosseous defects (>5 mm) and to confirm the safety of using autologous stem cells in clinical periodontal regenerative medicine. This is a single-centre, randomized, placebo-controlled study. This study has been approved by the ethical committees of School of Stomatology, Fourth Military Medical University. The study will be conducted according to the Declaration of Helsinki.
