Active clinical trials for "Periodontal Diseases"

There is a relationship between depression and periodontal disease. This relationship may be double-sided. A psychological state such as anxiety, depression, body image, and self-esteem may be affected from the symptoms of periodontal disease.

Amino acids (AAs) are organic molecules that are associated with inflammation and innate immunity diseases with critical roles in the cell repair and protection process. Our aim was to identify the free amino acids in saliva of a group of periodontitis patients and healthy individuals and additionally to assess their levels in different periodontal disease types and compare it to the healthy individuals.

Dental caries and periodontal disease are the two most common diseases in dentistry. Caries was caused by the acidic environment produced through the interaction of oral flora (biofilm) and fermentable food residues on the tooth surface over time thus to destroying the tooth structure. Periodontal disease was also highly associated with microorganisms in the periodontal tissues and the inflammatory response of the host that irritate and destruct periodontal and bone tissues. Recent studies have found that both stress and eating habits are associated with decline in oral health. Probiotics have been traditionally used for prevention and treatment of gastrointestinal diseases. In the past decade, accumulated studies further indicate that imbalance of oral microflora is highly related to oral diseases thus probiotics has been suggested for maintaining oral health. It is thus conceivable that probiotics as a buccal tablet may potentially restore the balance of oral flora providing a novel strategy to combat oral diseases. Such strategy may also harbor great opportunities for the long-term management of dental caries and periodontal infections. In order to evaluate the efficacy of probiotics buccal tablet in rebalancing oral flora and control to reduce the incidence of dental caries and periodontal diseases, the investigators aimed to conduct a comprehensive clinical trials for subsequent product optimization. Grape King Biotechnology Co., Ltd. has successfully developed oral tablet mainly composed of Lactobacillus plantarum GKD7 and Pediococcus acidilactici GKA4. These two probiotics were found to inhibit caries through producing protective biofilms thus are more effective than commercially available anti-tooth decay products. To evaluate the future potential of clinical applications of the related products series and the impact on oral health-related indicators, the investigators will explore the changes in the the following disease associated indexes before and after using the oral tablet. These include periodontal pocket depth, the gingival inflammation index, the plaque index, and the ratio of Firmicutes, Bacteroidetes, Streptococcus mutans, and Porphyromonas gigivalis, as well as quantification of total bacteria. This clinical study will be performed in Department of Stomatology in NCKUH in collaboration with periodontics session and Family Dentistry session. A total of 50 healthy individuals within the range of 20~65 years old will be enrolled.

The purpose of this study is to determine if regular rinsing with chlorhexidine is effective as a long-term preventive method for reducing the incidence of tooth loss in low income older adults. The true end-point of the study is tooth loss after five years of regular rinsing with chlorhexidine or a placebo; surrogate endpoints are periodontal disease, root and coronal decay.

The aim of the present study was to study if there are interactions and reduced clinical effect between chlorhexidine and fluoride when they are combined in the same mouthrinse.

This study aims to determine Oncostatin M (OSM), Leukemia inhibitory factor (LIF), and Interleukin-11 (IL-11) levels in gingival crevicular fluid (GCF), saliva, and serum in periodontally healthy individuals and those with gingivitis and chronic periodontitis before and after periodontal treatment and to evaluate the relationship between these cytokine levels and clinical periodontal parameters.

This is a phase 2 randomized controlled trial of pre-chemotherapy periodontal deep cleaning in Acute Myelogenous Leukemia (AML) patients with asymptomatic periodontitis. Once eligibility is confirmed, participants with periodontitis will be randomized in a 1:1 ratio to undergo treatment by scaling and root planing (SRP, "deep cleaning") (arm A) or receive no periodontal treatment (arm B). We will compare the incidence of Blood Stream Infection (BSI) during chemotherapy between the two arms. Study participation will continue until day 28 of chemotherapy or discharge from hospital, whichever occurs first.

The use of chlorhexidine or ozonized water in periodontal pockets accompanying NPT can provide a significant improvement in probing pocket depths compared to conventional treatment. However, the effect of subgingival ozonized water applications on VEGF and IGF levels, which are thought to play a role in the pathogenesis of periodontal disease and periodontal regeneration, should be examined.

This study aimed to investigate gingival crevicular fluid (GCF) and serum ErbB4 and Nrg4 levels in periodontal health and disease. A total of 80 individuals, 20 patients with stage II grade B periodontitis, 20 patients with stage III grade B periodontitis, 20 with gingivitis and 20 periodontally healthy individuals were included. Whole-mouth and site-specific clinical periodontal parameters including probing depth, clinical attachment level, bleeding on probing, gingival index, plaque index and papillar bleeding index were recorded. GCF and serum ErbB4 and Nrg4 levels were measured by enzyme-linked immunosorbent assay. Statistical analysis was performed by using non-parametric tests.

The aim of this study is; detection of leucine rich α-2 glycoprotein1 (LRG1), c-reactive protein (CRP) levels in saliva samples of periodontally healthy, gingivitis and periodontitis patients and the possible correlation between these values and clinical parameters of periodontal diseases. Materials and methods: Samples of saliva were obtained from 60 systemically healthy non-smoker individuals with periodontitis (P, n=20), gingivitis(G, n=20) and healthy periodontium (S, n=20). Full-mouth clinical periodontal measurements including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI) and plaque index (PI) were also recorded. Enzyme-linked immunosorbent assay (ELISA) was used to determine LRG and CRP levels in the biological samples.
