Active clinical trials for "Periodontitis"

Snuff use and smoking associated with poor periodontal health, especially if used together.

The aim is to study whether participants at risk could be identified using an aMMP-8 chairside mouth rinse test and to study if oral health and health behaviour is linked to the test result in Finnish adolescents.

Currently, the investigators are unaware of any previous studies that have analyzed the relationship between the prevalence of thyroid disease and chronic periodontitis among adults utilizing a retrospective, cross-sectional design. This study will review approximately 2000 patient records and compare the prevalence of thyroid disease in three groups with increasing severity of chronic periodontitis.

Post-treatment apical periodontitis is a fairly prevalent condition frequently caused by a persistent endodontic infection due to failure of the endodontic treatment. Microbial species in treated or untreated root canals were found to be different, with the former being less diverse and mainly characterized by Gram positive, facultative anaerobes bacteria than the latter. Enterococcus faecalis is the most frequently detected species in root-filled teeth in many studies (Zhang et al., 2015). In fact, E. Faecalis retains many virulence factors allowing adhesion to host cells and extracellular matrix, tissue invasion and damage through toxins release, as well as the ability to survive even in harsh environmental conditions. Further studies are needed to clarify E. faecalis prevalence among the different forms of pulpal and periapical lesions as well as its correlation with clinical symptoms.

The research question was to investigate whether non-surgical periodontal therapy could reduce cardiovascular risk markers in Coronary heart disease (CHD) patients.

Periodontitis is a prevalent inflammatory condition that destroys tooth-supporting structures. This condition is associated with pro-inflammatory mediators that utilize STAT3 as an activator of specific genes related to inflammation and tissue destruction. STAT3 has not been studied in the context of periodontitis in humans. We propose that STAT3 is associated with periodontitis. This knowledge might help to further our understanding of periodontitis pathology

Aim of the current study was to evaluate Endocan biomarker level in gingival crevicular fluid of patients with stage 1 or 2 (mild to moderate) periodontitis with controlled type 2 diabetes mellitus (DM) and compare it to that in DM free periodontitis patients.

To assess the association between periodontal parameters, serum lipid profile and Lp-PLA2 level in systemically healthy Chronic Periodontitis subjects and healthy controls.

Recent data found that peri-implantitis may differ from periodontitis at the histological level in terms of extent and composition of the cellular components. From human biopsies, it has been shown a deeper apical extension of the inflammatory cell infiltrate and a larger proportion of granulocytes and macrophages in peri-implantitis lesions compared to periodontitis lesions. Following experimental peri-implantitis, it has been observed a continuing bone loss around dental implants after ligature removal; whereas, such a progression was not observed around teeth after cessation of the experimental periodontitis. The factors influencing the recruitment and the activation of osteoclasts in both diseases have not been compared yet. Hypothesis : The more rapid and more severe alveolar bone destruction occurring in peri-implantitis compared to periodontitis is due at least in part to differences in the inflammatory process in these diseases. Aim: to study the cytokine profile produced by gingival explants from periodontitis or peri-implantitis sites and to test the consequences on alteration of bone remodelling activity using in vitro approach. Materials and methods The investigators will establish a collection of human gingival samples from patients undergoing surgical treatment of periodontitis or peri-implantitis. The investigators will test pro-inflammatory cytokines and chemokines release and consequences on osteoclast differentiation and activity.

Background and Objective: It has been reported that peripheral blood mononuclear cells (PBMC) from periodontal patients have a different profile of cytokine release when compared to the ones of healthy patients. Cigarette smoking is a recognized risk factor for periodontitis and is known to affect the systemic and local immune responses. Thus, the aim of the present study was to obtain preliminary data about the interaction of periodontal condition and smoking in the secretion of some cytokines by PBMC. Material and Methods: PBMC samples were isolated from 19 donors, divided into generalized chronic periodontitis (P; n=10) and periodontal health (H; n=9) groups. In addition, the smokers and non-smokers of each group were separately evaluated: SP- smokers with severe generalized chronic periodontitis (n=5); SH- periodontally healthy smokers (n=5); NSP- non-smokers with severe generalized chronic periodontitis (n=5) and NSH- periodontally healthy non-smokers (n=4). Cells were incubated for 24-48 hours in 500 µL wells containing RPMI 1640 and stimulated with 1.0 ng/mL of E. coli LPS. Supernatants were used to quantify the amounts of TNF-α, IL-6, IL-8 and IL-10 released using ELISA kits.
