Filter by: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. In this study, the investigators selected six periodontal disease-associated bacteria strains, including Porphyromonas gingivalis (Pg), Fusobacterium nucleatum (Fn), Actinobacillus actinomycetemcomitans (Aa), Tannerella forsythia (Tf), Treponema denticola (Td) and Prevotella intermedia (Pi) as diagnostic markers. Using real-time PCR and MALDI Biotyper, the investigators will establish the database of oral microorganisms in Taiwanese people, 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.
This study aimed at understanding the impact of educational pamphlet on Risk Perception of Periodontal Disease using A Randomised Clinical Trial model among patients in a Nigerian outpatient dental clinic
Due to the phenomenon of bacterial resistance, photodynamic therapy (PDT) has been studied as an alternative to the use of antibiotics on the periodontal treatment. However, the studies show several discrepancies between the parameters adopted for PDT, which makes it difficult to compare the results and measure their efficacy. The objective of this research was to investigate the tissue dosimetric parameters used in PDT for the treatment of periodontal disease. In order to achieve this objective, the scattering pattern of light in periodontal tissue, the concentration of methylene blue in the periodontal pockets and the number of viable microorganisms were evaluated. This clinical trial included 30 patients with chronic periodontitis according to the eligibility criteria. The patients were in periodontal treatment at the Dental Clinic at the University of Nove de Julho, where the research was carried out. Three incisors from each patient were selected for the experimental procedures. The pattern of light scattering was observed through intraoral photographs. A laser with emission of radiation with wavelength of 660 nm and 100 mW of power was used. The concentration of the photosensitizer (PS) in the periodontal pockets was evaluated by spectrometer before irradiation. Methylene blue was used as PS at the concentration of 100 μM in two different formulation and vehicles to evaluate the drug dimerization. Then, the procedures of irradiation of the PDT were carried out, with 3 irradiation times of 1, 3 and 5 min. The microbiological evaluation was performed from subgengival biofilms of the periodontal pockets of the experimental sites, before and immediately after the irradiation procedures.
In this randomized, controlled study, 18 patients with peri-implantitis were included. A total of forty dental implants were debrided with either ultrasonic instruments (test, n=20) or plastic scaler (control, n=20). Gingival recession depth (RD), keratinized tissue width (KTW), probing depth (PD), Gingival Index (GI) were evaluated at baseline and after 6 months. CBCT radiographs were used to evaluate peri-implant bone loss. Supportive and nonsurgical periodontal therapies were firstly consulted to reduce the inflammation, occurring due to the surgical treatments of the defects. The formation of bacterial biofilm on implant surfaces was removed by ultrasonic scaler and air polishing using abrasive powders or conventional plastic scaler with klorhegsidin combination.
The present study is an effort to investigate the hypothesis that Platelet Rich Fibrin/Biphasic Calcium Phosphate may play a role in inhibiting osteoclasts differentiation and in bone loss.
