Filter by:Generalized aggressive periodontitis (GAgP) is a multifactorial disease related to several aspects that influence its installation and progression. A constant microbial colonization, an altered inflammatory response, and a clear genetic factor are cited as possible factors associated with this pathology. Thus, aggressive periodontitis subjects could transmit for their descendants some genetical alterations, such as inflammatory response pattern associated with periodontal destruction and susceptibility to colonization by some pathogens, increasing the risk of develops this disease. This way, this project is aimed to evaluate the pattern of microbiological colonization and the inflammatory response pattern associated with it, comparing parents with generalized aggressive periodontitis and their children and periodontally healthy parents and their children. Thirty families will be selected and divided into two groups: Test group (n=15 families) families in which the parents (or at least one of them) present generalized aggressive periodontitis and one child (age ranging from 6-12 years old); Control group (n=15 families) families in which the parents (both of them) present periodontal healthy and one child (age ranging from 6-12 years old). The groups will be composed using a gender- and age-matched structure. The children will participate in a hygiene program and will be monitored for 3 months. All individuals (parents and children) will be clinically assessed for plaque and bleeding index, periodontal probing depth, clinical attachment level and gingival recession. During this period, samples of gingival crevicular fluid (GCF) and subgingival biofilm from periodontal pockets/sites from all subject (parents and children) will be collected. The GCF will be analyzed and the detection of interleukin (IL)-1β, IL-4, IL-6, IL-8, IL-10, IL-17, tumor necrosis factor (TNF)-α, and interferon (INF)-γ will be done using Luminex/MAGpix technology. In a subgingival biofilm, the DNA will be extracted and the microbiome and its functional characteristics will be evaluated by metagenomics and bioinformatics analysis. The data will be compared by Student's t-test, Mann-Whitney e Wilcoxon tests. The significance level for all analysis will be 5%.
This study is designed as a parallel, masked, randomized, placebo-controlled clinical trial to assess the clinical, microbiological, and immunological outcomes of scaling and root planning (SRP) or full-mouth ultrasonic debridement (FMUD) with AM (Amoxicillin + Metronidazole) for the treatment of Generalized Aggressive Periodontitis (GAgP).
The aim of the study was to compare the clinical effects of systemic use of doxycycline to amoxicillin plus metronidazole as adjunctive treatment in nonsurgical debridement of aggressive periodontitis (AgP). Twenty four patients with aggressive periodontitis were enrolled in this clinical study. They all received oral hygiene instruction and full-mouth nonsurgical debridement using manual instruments. The test group received as adjunctive antibiotic treatment 200 mg of doxycycline the first day followed by 100 mg per day during 14 days. The control group received 500 of amoxicillin and 250 of metronidazole, three times a day for 7 days.
Generalized aggressive periodontitis (GAP) is an inflammatory disease that causes the severe and rapid destruction of periodontal tissue. A relatively constant microbiological pattern, an altered inflammatory condition and familial aggregation of cases were described as important characteristics of this disease. In this vein, studies evaluating children of GAP patients were made and identified early microbiological and inflammatory alterations in this population, suggesting that these factors could favor the disease development. Thus, the aim of this project is to evaluate if the use of toothpaste with Triclosan could have a beneficial effect in control the microbiota and the inflammatory condition in children from parents with GAP, comparing them to children of periodontally healthy parents. 20 children (6-12 years old) from GAP parents and 20 children (6-12 years old) from periodontally healthy parents will be selected and will participate in a cross-over placebo study. All children will be included in a 15-day period of control of plaque to standardize the hygiene technique using only the placebo toothpaste. After this period, the children will be divided randomly into 4 groups: G1: Triclosan/health children; G2: Placebo/health children; G3: Triclosan/GAP children; G4: Placebo/GAP children and they will use the specific paste described for each group for 45 days. After this period, all children will repeat the 15 days interval, using only the placebo toothpaste, to remove the Triclosan effect and to standardize the oral hygiene again. Posteriorly, the crossing of groups will be done and children will be reallocated to change the used toothpaste. Thus, children that were in G1 will be reallocated in G2, children of G2 will be reallocated in G1, children of G3 will be in G4 and children of G4 will be in G3, staying in this new group for more 45 days. The evaluated periods will be baseline, 15 days, 30 days and 45 days while children stay in G1, G2, G3 or G4. In these periods children will be clinically evaluated for the periodontal parameter and sample collection of crevicular gingival fluid (GCF) and subgingival biofilm from incisors and molars will be done. Luminex/MAGpix technology will be used to detect IL-1β, IL-4, IL-6, IL-8, IL-10, IL-17, TNF-α, INF-γ in the GCF. The subgingival biofilm will be used to evaluate the Porphyromonas gingivalis, Tannerella forsythia, Aggregatibacter actinomycetemcomitans levels by real-time PCR.
Present study intended to compare diseased and healthy sites in chronic and aggressive periodontitis with healthy individuals. The investigators suggest that even unaffected healthy sites of both chronic and aggressive periodontitis patients exhibit subclinical inflammation and tissue destruction with decreased fibroblast cell counts and increased inflammatory cell counts. Investigators also suggest that a possible mechanism which might play a role in the disease progression might occur via a disbalance between matrix metalloproteinases and their inhibitors, and increased hypoxia in diseased sites.
Smoking is the major preventable risk factor in the initiation and progression of periodontal diseases. Periodontitis risk was found to be 3.9 times higher among smokers aged between 19-30 years and 2.8 times higher among smokers aged 31-40 years compared to non-smokers. Aggressive periodontitis (AgP), is characterized by a rapid attachment loss usually incompatible with the amount of plaque and dental calculus. It is often not possible to predict the prognosis of treatment with various treatment options in cases of aggressive periodontitis. It was hypothesized that non-smoker patients with generalized aggressive periodontitis (GAgP) will respond better to conventional mechanical non-surgical periodontal therapy compared to the smokers. Therefore, the aim of this study was to evaluate the effects of smoking on the outcomes of non-surgical periodontal treatment in terms of the clinical, biochemical and microbiological parameters.
Generalized aggressive periodontitis (GAgP) is a distinct type of periodontal disease characterized by rapid loss of attachment and alveolar bone occuring in young individuals. Photodynamic therapy (PDT) was introduced in periodontology as an adjunctive approach to non-surgical periodontal treatment (NPT) in periodontitis patients. In this trial, it was aimed that to evaluate the clinical and microbiological effects of adjunctive PDT to NPT in patients with GAgP. In this prospective controlled clinical study, 24 systemically healthy, non-smoking subjects with GAgP were enrolled. Subjects were randomly assigned to a control group (n=12) treated with NPT only or to a test group (n=12) treated with NPT and PDT. Plaque index, sulcus bleeding index (SBI), pocket depth (PD), relative attachment level, gingival recession, mobility were recorded at baseline and on day 63. Microbiological samples were obtained fom the sites with PD ≥5 mm at the same time points and evaluated for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola using micro-IDent test.
The aim of the present study is to evaluate the clinical response of proximal furcations treated with enamel matrix derivative proteins (EMD).
This study evaluates the interaction between host immune cells and bacteria associated with periodontitis. It comprises biological material from donors with and without periodontal disease. Specifically, we collect a spit and blood sample to conduct in vitro stimulations and measurements of selected parameters related to periodontitis to clarify obscure areas in the immunologic pathogenesis of this disease.
To assess the local effect of the antimicrobial therapy using clarithromycin association with photodynamic therapy (PDT) in the treatment of generalized aggressive periodontitis (GAgP).
