Filter by:The purpose of the study was to evaluate, from a microbiological point of view, microbiota around teeth and implants in the same patient affected by periodontal disease and peri-implant disease, all compared with a healthy tooth. From the identification of particular bacterial species in the examined sites, it is intended to be traced back to the identification of a clear etiopathogenic process, which may shed light on the similarities and differences between the two diseases. In recognition of these mechanisms, the investigators think to develop new therapeutic strategies for the future.
Recent studies have shown that the systemic inflammation caused by periodontal disease (PD) can determine important changes in the coronary arteries, favoring atherosclerosis progression and development of acute coronary syndromes (ACS). The aim of ATHERODENT study is to assess the interrelation between PD, inflammation and progression of coronary atherosclerosis in patients with ACS. Material and methods: This case-control observational study will enroll 100 patients (group 1 - ACS and associated PD, and group 2 -ACS and no PD), in whom the following data will be collected: (1) demographic and clinical data, (2) cardiovascular risk factors, (3) full characterization of PD markers, (4) systemic inflammatory biomarkers, (5) imaging biomarkers derived from transthoracic echocardiography, computed tomography, coronary angiography, optical coherence tomography and intravascular ultrasound, and (6) assessment of the presence of specific oral bacteria in samples of coronary plaques collected by coronary atherectomy, which will be performed during percutaneous revascularization interventions, when indicated in selected cases, in the atherectomy sub-study. The follow-up will be performed at 1, 3, 6, 12, 15, 18 and 24 months. The primary endpoint of the study will be represented by the rate of major adverse cardiovascular events (MACE rates) in PD vs non-PD patients and in correlation with: (1) the level of systemic inflammation triggered by PD and/or by ACS at baseline; (2) the vulnerability degree of atheromatous plaques in the coronary tree (culprit and non-culprit lesions); and (3) the presence and burden of oral bacteria in atheromatous plaques. Secondary endpoints will be represented by: (1) the rate of progression of vulnerability degree of non-culprit coronary plaques; (2) the rate of progression of atheromatous burden and calcium scoring of the coronary tree; and (3) the rate of occurrence of left ventricular remodeling and postinfarction heart failure.
The quantification of the proteomes : L-plastin, lipocalin and adiponectin was analysed in the subgingival tissue samples of generalized severe chronic periodontitis patients with and without diabetes mellitus.The demographic and the periodontal parameters were assessed and the correlated with the quantification of the proteins. The mRNA expression was analyzed with RT-PCR and the quantification of protein was done using ELISA.
The goal of this study is to evaluate if dental pulp stem cells (DPSCs) delivered into intrabony defects in a collagen scaffold would enhance the clinical and radiographic parameters of periodontal regeneration.
Periodontitis is related to host genetics, constitution of the dental biofilm and environmental factors such as smoking. DNA methylation is a mechanism of genetic expression that can inhibit or silence gene expression. In this way several researchers have been dedicated to study the genetic influence on the susceptibility and / or increased risk to periodontal disease. Studies have reported association between several epigenetic biomarkers with periodontal inflammation. Considering the hypothesis that there is an association between smoking and methylation in genes related to periodontal disease, the objective of this study was to verify the DNA methylation pattern in oral epithelial cells of patients with chronic periodontitis (CP) in the promoter of a specific gene involved in the control of inflammation, as suppressor of cytokine signaling (SOCS) 1 in smokers and nonsmokers patients.
Background: Melatonin is an endogenous indoleamine synthesized mainly by pineal gland and showed anti-inflammatory and antioxidant properties. Moreover, melatonin promotes osteoblastic differentiation and suppresses osteoclastic formation. This randomized clinical trial (RCT) was aimed to assess the additive effect of melatonin supplementation in generalized chronic periodontitis (gCP) patients with insomnia who received scaling and root planing (SRP). Methods: Seventy four gCP patients with primary insomnia participated in this 6-month RCT and randomly distributed between two groups. Melatonin group (MTN+SRP group, n=38) included patients who were subjected to SRP with a 2- month regimen of 10 mg oral melatonin supplementation capsule once daily at bed-time. In the control group (Placebo+SRP group, n=36), SRP was performed for participants provided with matching placebo capsules. The primary treatment outcome included the clinical attachment gain (CAG) after 3 and 6 months of therapy, whereas, the changes in pocket depth ,bleeding on probing (BOP%) and salivary tumor-necrosis factor-α (TNF-α) levels represented the secondary outcomes.
The purpose of this study was to demonstrate in patients with generalized chronic periodontitis that switching from cigarette smoking to using IQOS improves the response to periodontal therapy and the overall oral health status compared to continuing cigarette smoking. Note: "IQOS" is the Tobacco Heating System (THS) with Marlboro Heatsticks, marketed in Japan under the brand name IQOS
More than ninety percent of adults in Taiwan are suspected to carry periodontal disease, which causes bad breath, swollen and bleeding gums, plaque and even tooth loss. Half of the patients, however, are ignorance these clinical syndromes because of no obvious pain. A lot of researches show that periodontal disease is related to diabetes mellitus. Periodontal disease causes rise of blood sugar, and more than 3 times as diabetes mellitus patients as healthy people have serious periodontal disease.In this study, the investigators collect periodontal pocket and saliva samples of participants, and selecting six periodontal disease-associated bacteria strains, including Porphyromonas gingivalis (Pg), Fusobacterium nucleatum (Fn), Actinobacillus actinomycetemcomitans (Aa), Treponema denticola (Td), Prevotella intermedia (Pi) and Tannerella forsythia (Tf) as diagnostic markers. Participants will get bacteriostasis mouthwash at mouth 2. The investigators will compare the differences of blood biochemistry value and oral bacteria strains after using the mouthwash.Using real-time PCR and MALDI Biotyper, the investigators will establish the database of oral microorganisms in diabetes mellitus patients, providing periodontal disease clinical markers of high-risk groups and the basis for personal medicine of therapy in the future.

Background: The purpose of the present study is to research whether stress scale scores alter with relationship to gingival inflammation and examine the impact of non-surgical periodontal therapy during pregnancy on the levels of cytokines in gingival crevicular fluid (GCF) and on salivary stress-related hormones. Methods: 30 non-pregnant (control group) and 30 pregnant women (test group) who fulfilled the study inclusion criteria were chosen. The participants with moderate/severe gingivitis were included. Clinical data and samples of GCF and salivary were collected at baseline and after periodontal therapy. The levels of cytokines interleukin-1 beta (IL-1β) and IL-10, and concentration of salivary chromogranin A (Cg A) hormone were analyzed by enzyme-linked immunosorbent assay kits.
