View clinical trials related to Chronic Periodontitis.
Filter by:Periodontal diseases are complex chronic pathologies presenting a high prevalence worldwide. Etiopathological process involved in initiation and progression of these multifactorial diseases are not well understood, explaining the huge clinical forms variability and the complexity of the currently used classification of periodontal diseases. Recently, the implication of antimicrobial peptides (AMPs) have been suggested as potential track of explanation for periodontal diseases pathogeny. The here presented study explore the level of expression of genes coding those peptides by studying periodontal smears obtained from healthy and periodontitis patients.
The purpose of this study is to determine whether Lactobacillus reuteri-containing lozenges (Prodentis) are effective in treatment of halitosis in patients with chronic periodontitis.
The aim of this study was to formulate a mucoadhesive gel of grapes seed extract (GSE) followed by short-term clinical study for the effectiveness of this gel onto the pocket depth (PD), plaque index (PI), gingival index (GI), and bleeding on probing (BOP) when applied in periodontal pockets as an adjunct treatment for chronic periodontitis.
The study was aimed to investigating changes in periodontal parameters and superoxide dismutase activity after root surface debridement with and without Omega 3 fatty acids (ω-3 FAs) supplementation in postmenopausal women. Adjunctive Omega 3 fatty acids supplements reduce periodontal inflammation and improve the status of systemic enzymatic antioxidants in postmenopausal women.
The purpose of this double-masked, randomized, controlled clinical trial was to evaluate the effects of subgingival delivery of boric acid gel as an adjunct to scaling and root planing (SRP) on clinical and radiographic parameters and compare this method with SRP plus placebo gel alone in patients with chronic periodontitis (CP).
The aim of this study was to compare the clinical and microbiological outcomes of different dosages of metronidazole (MTZ) and of the duration of the systemic administration of MTZ and amoxicillin as adjunct to scaling and root planing (SRP) in the treatment of generalized chronic periodontitis (GChP).
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.
Summary The aim of this study is to evaluate through clinical, microbiological and immunological parameters using PLGA microspheres (lactic-co-glycolic acid polyacid) containing doxycycline in periodontal therapy in smokers with chronic periodontitis. For this study, 40 patients will be selected, with an average age between 30 and 59 years old of both genders (male and female), who spontaneously seek the clinic graduate of the Piracicaba Dental School -FOP / UNICAMP, and exhibiting at least four bleeding sites, including 2 sites with a probing depth (PD) between 5 and 6 mm and two sites PS ≥7 mm in uniradiculares teeth. Patients should have a minimum of 20 teeth. Will be excluded from relevant systemic disease carriers or antibiotics used in the 6 months preceding the study. All patients will receive oral hygiene instruction and will undergo a pre-treatment, which will be held supragingival sweeps and removal of plaque retentive factors. Patients will be divided into 2 groups (DB + DOX: Debridement + Doxycycline, test group and DB: only debridement, control group) of 20 patients who will receive the following treatments: periodontal debridement ultrasound for 45 minutes associated with the local administration of 1 mg microspheres containing doxycycline, or just mechanical debridement, for each selected site. Will be assessed the following clinical parameters: gingival index (GI) Plaque Index (PI), Bleeding on Probing (BOP), Position of the gingival margin (PGM), Probing Depth (PD) and Relative Clinical Attachment Level (RCAL). The microbiological evaluation will be made by means of polymerase chain reaction - real time ( "real time" - PCR) to detect bacteria: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans and Prevotella intermedia. The enzyme immunoassay (LUMINEXMAGPIX) allow the detection of cytokine levels of GM-CSF, INF-γ, IL-10, IL-12, IL-13, IL-1β, IL-4, IL-6, IL-8 and TNF-α. The analysis of the proteolytic enzyme activity is accomplished by using zymography to assess MMP-8 and MMP-9. The described parameters will be evaluated at baseline, 45 and 90 days after the initial visit. The results are compared statistically by analysis of variance with repeated measures with 5% significance level.
The investigators primary objective in this clinical intervention study, therefore, was to explore the impact of omega-3 PUFAs in conjunction with scaling and root planing on salivary markers (in patients with chronic periodontitis.
Patients visiting National Hospital of Odonto-Stomatology for treating periodontitis used a food supplement (lozenge) containing chicken egg antibody (IgY) against Porphyromonas gingivalis gingipains as an adjunct to conventional scaling and root planing (SRP). After 8 weeks the patients were examined against. Parameters including probing depth (PD), bleeding on probing (BOP), number of P. gingivalis in periodontal pockets were evaluated and compared to the control group that had used placebo lozenges.
