OBJECTIVES An interrelationship between rheumatoid arthritis (RA) and periodontitis has been suggested due to their common pathogenic mechanisms. Protein carbamylation and neutrophil extracellular traps (NETs) formation have been shown to be related to autoimmune conditions, including RA, but their association with periodontitis has not been elucidated. Therefore, we assessed whether or not cir...

Background: The observational relationship between obesity and periodontitis is widely known, yet causal evidence is lacking. Our objective was to investigate causal associations between periodontitis and body mass index (BMI). Methods: We performed Mendelian randomization analyses with BMI-associated loci combined in a genetic risk score (GRS) as the instrument for BMI. All analyses were condu...

Periodontal diseases are a collection of inflammatory processes that affect the periodontium, that is, the teeth supporting tissues. Gingivitis (infected red swollen and easily bleeding gums) is a mild reversible form of periodontal disease. Almost 100% of the population suffers from time to time from gingivitis. Gingivitis can develop into periodontitis, which is a chronic inflammatory disease...

Periodontitis is one of the most prevalent oral diseases. In this study, we probed the nationwide registered database to assess the time trends of prevalence of periodontitis in Taiwan.A retrospective study was conducted to analyze the registered database compiled by the National Health Insurance provided by the Department of Health, Taiwan, from 1997 to December 2013.We found that the prevalen...

Results from epidemiological studies suggest that there is an association between periodontitis and prediabetes, however, causality is not known. The results from our previous studies suggest that induction of periodontitis leads to hyperinsulinemia glucose intolerance and insulin resistance, all hallmarks of prediabetes. However, global effects of periodontitis on critical organs in terms of m...

Background Diabetes and periodontitis are interrelated, and patient education and guidance are important. Therefore, we conducted a periodontitis care program for patients with type 2 diabetes to provide education about diabetes and periodontitis and to promote self-care skills, and we evaluated the effectiveness of this program. Methods This was a randomized controlled trial. Thirty-eight an...

BACKGROUND/AIMS This study examined prevalence and risk factors of periodontitis in representative samples of Korean adults, with and without diabetes mellitus (DM). METHODS Data from the 2012 Korean National Health and Nutritional Examination Survey were analyzed. A total of 4,477 adults (≥ 30 years old) were selected from 8,057 individuals who completed a nutrition survey, a self-reported g...

Objective. Alanine Aminotransferase is an enzyme associated with not only liver diseases, liver conditions, and metabolic syndrome, but also inflammation. Periodontitis is associated with increased cytokines and other markers of inflammation. The purpose of this study is to determine if an independent association between Alanine Aminotransferase and periodontitis exists. Methods. Data from the ...

BACKGROUND Proinflammatory and anti-inflammatory cytokines play a key role in the pathogenesis of periodontal diseases. Secretion of bioactive IL-35 has been described by T regulatory cells (T(regs)) and is required for their maximal suppressive activity. T(regs) are involved in the modulation of local immune response in chronic periodontitis patients. OBJECTIVE Hence, the present study was a...
