Active clinical trials for "Periodontitis"

Periodontal diseases are chronic diseases that occur as a result of a violation of the balance between microbial dental plaque and the host response. Gingivitis is a disease characterized by inflammation of the gums that occurs in one or more areas without loss of attachments.1 in periodontitis, an inflammatory event that begins in the gum along with gingivitis spreads to the periodontal ligament, alveolar bone and soft tissues that support the tooth, causing the destruction of these structures.2 Cytokines are low molecular weight proteins that participate in the initial and active stages of inflammation and immunity. In periodontal disease pathogenesis, cytokine response has been reported to play a very critical role in determining disease progression.3 IL-1beta, MIP-1alfa and G-CSF are key cytokines in chronic inflammatory diseases and have the potential to initiate bone loss and tissue destruction seen in periodontal disease.4the purpose of this study; it is to determine the degree of inflammation and periodontal destruction by determining the levels of IL-1beta, MIP-1alfa, G-CSF cytokines in the gum groove fluid of periodontal healthy and diseased individuals.

The role of micro-RNAs in chronic periodontitis associated with CAD is still in an incipient stage needs to be explored further. The investigators attempt to quantify and compare the levels of micro-RNA 146a and micro-RNA 126 in subgingival as well as coronary plaque samples obtained from patients diagnosed with chronic periodontitis with and without coronary artery disease.

Healing of post-extraction alveolus is a complex process that involves soft and hard tissues regeneration. Pain, swelling, difficulty of opening the mouth, delayed healing of bone tissue, alveolitis and horizontal or vertical resorption of bone tissue are the main problems that have impact on consequent treatment. Blood concentrates PRGF (plasma rich in growth factors) and PRF (platelet-rich fibrin), which are rich in growth factors, create better conditions for post-extraction alveolus healing and enhance quality of soft tissues and bone regeneration. Our study objective was to compare physiological healing of post-extraction zone, PRF and PRGF induced changes of healing process. Methods that we used: 43 patients were randomly divided into 3 groups: I control group - lower molar extraction and filling of post-extraction alveolus with hemostatic sponge containing gentamicin, II group - post-extraction alveolus is filled PRGF and III group - post-extraction alveolus is filled with PRF. Bone regeneration was evaluated in CBCT scans after 1 month. Pain was evaluated using visual analogical scale (VAS).

Preeclamptic women with and without chronic periodontitis were recruited for the study. Subgingival plaque samples and placental tissue samples(postpartum) were obtained from the participants for the microbial analysis(bacteria, viruses) and MIR155 levels and comparison was done among groups. this study was designed in order to evaluate the role of periodontal microorganisms in preeclampsia and to find compare the MIR155 levels among participants, so as to check its importance as a biomarker for inflammatory disease like preeclampsia.

Inflammation is a common factor of chronic periodontitis and diabetes. However, to date, there is no scientific evidence supporting a causal effect of the inflammation created by apical periodontitis on the onset of insulin resistance and on metabolic derangement in the condition of pre-diabetes or diabetes. A case control study has been designed in order to evaluate serum levels of pro-diabetes inflammation factors in a sample of healthy patients between 25 and 55 years of age, with or without apical periodontitis,before endodontic treatment and at 6 and 12 months post-treatment. The aim of the study is to evaluate any relation between the presence of chronic endodontic lesions and pro-diabetes inflammation factors that can promote the onset of insulin resistance, and whether endodontic treatment can reduce these factors, thus preventing a pro-diabetes status.

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%.

Periodontitis is a chronic oral infection that results in the breakdown of connective tissue and alveolar bone that support the teeth. Non-surgical sanative therapy using a combination treatment of hand and ultrasonic instrumentation is the primary treatment option for patients with periodontitis. However, the hand-held instrumentation requires continuous sharpening for optimal outcomes, which introduces tremendous variability as well as a large increase in time spent by the treating dental hygienists. Therefore, this study aimed to determine if ultrasonic instrumentation alone can provide similar improvements to periodontal outcomes compared to ultrasonic plus hand instrumentation.

This case control-study measures the levels of Interleukin-17 in gingival crevicular fluid and placental tissue samples of pregnant females as a possible marker in determining whether or not an association exists between chronic periodontitis and preterm labor. Interleukin-17 is a pro-inflammatory cytokine whose levels have been proven to increase in periodontal disease.

Aim The Aim of the current study is to establish the association between periodontitis and adverse pregnancy outcomes in metabolic syndrome (Mets) patients and to evaluate the effect of intervention. Objectives To evaluate the changes in periodontal status of pregnant women with metabolic syndrome after non surgical periodontal therapy (NSPT) To evaluate the inflammatory marker levels in serum of pregnant women with metabolic syndrome after non surgical periodontal therapy To evaluate the effect of NSPT on adverse pregnancy outcomes of women with metabolic syndrome

Melasma is a commonly pigmention characterized by melanotic patches on the face. literature searched revealed that periodontitis and vitamin D deficiency have occurred along with anemia. Actinic associated factors may be indirectly related to vitamin D, melasma contributes to sun exposed area of face.To correlate melasma with clinical evidence of periodontitis and vitamin D serum analysis along side hb %. Patients with facial melasma between 30-70yrs of either gender formed Group A (95). Anaemia and periodontitis were Clinically checked. Additionally serum analysis of vitamin D and hb percentage were analysed. Similar procedure was carried out on controls which had Group B (95) patients with no melasma on face. The study revealed significant correlation between melasma and periodontitis with vitamin D abnormalities (p value<.05), where as insignificant correlation between melasma and Hb%. The correlation between melasma, vitamin d changes and periodontitis may prompt the clinician to check for any such changes in any patient. Melasma in patients with periodontitis and serum vitamin D changes might be a considered as a syndrome.
