Periodontitis and rheumatoid arthritis (RA) are both widespread multifactorial diseases, characterized by chronic inflammation leading to tissue and bone destruction around teeth or joints, respectively. An association between periodontitis and RA has been proposed, suggesting that the periodontal pathogen Porphyromonas gingivalis (P. gingivalis) may be involved in the generation of anti-citrul...

Background: Rheumatoid Arthritis and Chronic Periodontitis are two chronic inflammatory disorders which share a similar pathophysiology. Previously many studies have proposed a relationship between both the diseases. Therefore, the aim of the study was to explore the co-relation between grading of Rheumatoid arthritis and severity of chronic periodontitis in south Indian population. Material An...

Both periodontitis and osteoporosis have similar sign of bone resorption in nature. However, the relationship of the severity between these 2 bone-loss diseases is still uncertain.The aim of this study was to investigate the association between the severity of osteoporosis and periodontitis regarding the impact of oral hygiene maintenance. In total, 35,127 osteoporosis patients and 50,498 compa...

Objectives: Periodontal pathogens need acidic environments to proliferate in periodontium, and their growth is affected by the salivary flow rate and pH of the mouth. Alterations in flow and acidity of saliva have an important effect on oral diseases such as periodontitis. This study was designed to compare salivary pH and flow rate before and after using green tea, black tea and coffee in pati...

For the problem of stabilization of mildly nonlinear systems with saturated control, a simple and computationally attractive method of designing a stabilizing gain scheduled output feedback is proposed. The resulting controller is characterized by an eecient use of the actuator capacity (\agressive" control), and is supplied with rigorously proven input/output performance bounds. In particular,...

Periodontitis and osteoporosis are primary concerns in public health and clinical management. The aim of this study was to investigate the association between periodontitis and osteoporosis by gender.Data were retrieved from the National Health Insurance Research Database, Taiwan. A diagnosis of periodontitis was defined on the basis of subgingival curettage, periodontal flap operation, and gin...

AIM Assess the association of flossing with periodontitis. MATERIALS AND METHODS This was a cross-sectional study using the National Health and Nutrition Examination Survey (NHANES) years 2011-2014. We used three categories of flossing: 0-1, 2-4 and ≥5 days in the past week and the CDC definition of periodontitis. We calculated odds ratios controlling for age, gender, smoking, drinking, incom...

AIM Periodontitis is one of the major problems slowly progressing and could affect 70% of the global population. The prevalence of periodontitis differs from mild to moderate forms of race and geographic region. The aim of this study is to determine the acid phosphatase (ACP) activity in the gingival tissues of periodontitis subjects. In this study, the activity of ACP in the gingival tissue of...

AIM Periodontitis is a chronic inflammatory disease, characterized by irreversible destruction of tooth-supporting tissue including alveolar bone. We recently reported mucin 4 (MUC4) and matrix metalloproteinase 7 (MMP7) as highly associated with periodontitis in gingival tissue biopsies. The aim of this study was to further investigate the levels of MUC4 and MMP7 in saliva and gingival crevicu...

BACKGROUND The aim of the present study was to identify the long-term major adverse cardiovascular events (MACE) in treated periodontitis patients in Taiwan. METHODS From the National Health Insurance Research Database (2001-2010), adult patients (≥ 18 years) with treated periodontitis were identified. Comparison was made between patients with mild form and severe form of treated periodontiti...
