Active clinical trials for "Periodontitis"

The purpose of this study is to determine whether ST266 will reduce pocket depth (PD) as an adjunctive to scaling and root planing (SRP) in subjects with moderate to severe periodontal disease.

Chronic periodontitis (CP) is an infectious disease resulting in inflammation of the supporting structures of the teeth, progressive loss of bone loss and insertion. The aim of this study is to evaluate the effects of antimicrobial Photodynamic Therapy (aPDT) as adjuvant to periodontal surgery treatment (PST) in patients diagnosed with generalized severe chronic periodontitis (GSCP). Twenty patients with a clinical diagnosis of CP will be treated in a split-mouth design study to either aPDT associated with surgical access for scaling and root planning (SASRP) or SASRP only. aPDT will be performed by using a laser light source with 690 nm wavelength associated with a phenothiazine photosensitizer. The applications will occur in only one episodes. All patients will be monitored for 30 and 90 days after PST. Clinical assessment of plaque index, probing depth, clinical attachment level and bleeding on probing will be performed at baseline (pre-intervention period) and 30 and 90 days after the PST. Subgingival plaque samples will be collected (at baseline and 30 and 90 days after the PST) and the counts of 40 subgingival species will be determined using DNA-DNA checkerboard hybridization. Data obtained will be statistically analyzed.

The objective in this case-control intervention study, therefore, was to explore the effect of nonsurgical periodontal therapy on the GCF levels of chemerin and IL-6 in patients with chronic periodontitis in order to determine the usefulness of chemerin as a diagnostic and prognostic biomarker of periodontal disease.

The aim of this study is to investigate the effects of Azithromycin (systemic and locally) on the clinical and microbiological parameters of periodontal in patients with chronic periodontitis.

This is a 9 month randomised controlled clinical comparing the clinical efficacy of 1%metformin and 1%alendronate in chronic periodontitis subjects.

In the past few years, studies have evaluated the effect of systemic use of sodium alendronate, especially in the treatment of structural bone defects caused by periodontal diseases. This study evaluated the effects of non-surgical periodontal treatment associated with the topical application of 1% sodium alendronate on clinical and topographical parameters. Chronic periodontitis patients were recruited for the present study and were monitored at 3 and 6 months after baseline examinations. A placebo gel was used as control.

Gum disease is a common disease, which affects 45% of the UK adult dentate population. It is caused by bacteria in dental plaque, which produces inflammation and a deepening of the natural crevice between the gum and the tooth surface. A crevice of 3mm is considered to be within the normal range, but anything ≥4mm is considered to be abnormal and is called a "pocket". Standard treatment of gum disease is mechanical cleaning aimed at removing bacteria off the root surfaces of the teeth. For most teeth, in the majority of patients, this can be achieved by root surface debridement (RSD), which involves passing instruments into the gum pockets to clean the roots. Previous studies have shown that the outcome of treatment is less effective when the pockets are deeper, or where there is bone or root anatomy which makes access for RSD difficult. In such instances additional approaches, such as repeating RSD, surgical access, or the additional use of antibiotics are considered. This clinical study will investigate the benefits and drawbacks of using a light source and dye (photodynamic therapy - PDT) as an additional treatment compared to the standard treatment of RSD alone. Patients with chronic gum problems who have undergone 1 cycle of RSD, but have residual pockets will be invited to join the study. All residual pockets will be treated with the conventional treatment of RSD. Following a random allocation process the residual pockets in half the mouth will receive additional treatment with PDT at the same appointment. Patients will be followed up for 3 months to evaluate the clinical benefits and any side effects. The aim of the study is therefore to evaluate if this localised, simple treatment can add benefit to RSD alone, thus reducing the need for antibiotics or surgery to treat residual pockets.

The aim of this study is to evaluate the additional effect of antimicrobial photodynamic therapy regeneration treatment of mandibular furcation lesions when associated to bovine bone and porcine collagen membrane.

The present study is designed to evaluate the combined efficacy of Platelet Rich Fibrin (PRF) and 1.2% Rosuvastatin (RSV) with open flap debridement (OFD) in treatment of intrabony defects in chronic periodontitis patients

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.
