Cardiovascular diseases, chronic obstructive pulmonary diseases, diabetes, rheumatoid arthritis, and cancer are the most common noncommunicable diseases (NCDs). These NCDs share risk factors with periodontal disease (PD), a preventable risk factor linked to lifestyle. The discussion regarding the association between these chronic diseases is more complex. There is still a significant knowledge gap particularly of the causal relationship between PD and NCDs. In this paper, we present fundamental knowledge of the mechanisms and roles of putative periodontal bacteria to gather several hypotheses, evidence that clinical studies thus far have not produced. Although the causal hypotheses are not yet clearly established on a biological basis, prevention and prophylactic measures are recommended to prevent even the possibility of such potential risk factors.

Periodontal Pathogens as Risk Factors of Cardiovascular Diseases, Diabetes, Rheumatoid Arthritis, Cancer, and Chronic Obstructive Pulmonary Disease-Is There Cause for Consideration?

The effect of periodontal treatment on patients with rheumatoid arthritis: The ESPERA randomised controlled trial.

BACKGROUND The association of periodontitis (PD) with the prevalence of rheumatoid arthritis (RA) remains controversial. Therefore, the aim of this study was to evaluate their correlation and investigate the effects of non-surgical periodontal treatment on RA. MATERIAL AND METHODS A total of 64 patients were enrolled in this study and divided into 4 groups: 18 PD patients (PD+RA-), 18 RA patients (PD-RA+), 18 RA with PD patients (PD+RA+), and 10 healthy controls (PD-RA-). Periodontal and rheumatologic parameters were examined at baseline and 1 month following non-surgical periodontal treatment. RESULTS Our results showed that RA patients had similar periodontal status. However, patients in the PD+RA+ group had significantly higher levels of rheumatologic parameters such as C-reactive protein (CRP), anti-cyclic citrulline peptide antibody (ACPA), erythrocyte sedimentation rate (ESR), and Disease Activity Score 28 (DAS28) than those in the PD-RA+ group. In addition, non-surgical periodontal treatment was efficacious in improving rheumatologic parameters of patients in the PD+RA+ group. CONCLUSIONS The presence of PD might contribute to the progression of RA, while RA might have little effect on accelerating the development of PD. In addition, RA patients with PD receiving non-surgical periodontal treatment resulted in noteworthy improvement in the clinical outcome for RA.

Association of Periodontitis with Rheumatoid Arthritis and the Effect of Non-Surgical Periodontal Treatment on Disease Activity in Patients with Rheumatoid Arthritis.

BACKGROUND The aim of this cross-sectional study was to investigate clinical periodontal findings as well as prevalence of selected potentially periodontal pathogenic bacteria in patients with rheumatoid arthritis (RA) treated with different immunosuppressive rheumatic medications. METHODS One hundred sixty-eight patients with RA undergoing different immunosuppressive medications were included and divided into subgroups according to their medication, which was taken in the past 6 months, in detail, 1) non-steroidal anti-inflammatory drugs (NSAID) and glucocorticoids combined, and the following different disease modifying anti-rheumatic drugs (DMARDs): 2) methotrexate (MTX), 3) leflunomide, 4) MTX and TNF-α antagonists combined, 5) interleukin-6 (IL-6) antagonist, 6) MTX and rituximab combined, and 7) combination therapies of > 2 of these DMARDs. Periodontal examination consisted of papilla bleeding index (PBI), periodontal status with periodontal probing depth (PD), bleeding on probing (BOP), and clinical attachment loss (AL). Periodontitis was classified as none/mild, moderate, or severe. Samples obtained from gingival crevicular fluid were analyzed for presence of 11 periodontal pathogenic bacteria. RESULTS Patients with MTX + TNF-α antagonists therapy showed higher PBI and BOP values compared with leflunomide (P < 0.01) and higher BOP than MTX + rituximab (P = 0.02). Porphyromonas gingivalis (P < 0.01), Treponema denticola (P < 0.01), Fusobacterium nodatum (P = 0.02) and Capnocytophaga species (P = 0.05) was associated with medication subgroup, whereby post hoc testing confirmed singular differences for several medication subgroups. CONCLUSIONS RA medication is associated with periodontal inflammation, without differences in periodontal disease severity. Thereby, combination of MTX + TNF-α shows an increased potential to periodontal inflammation. Additionally, several differences in prevalence of selected bacteria were detected.

Association of different immunosuppressive medications with periodontal condition in patients with rheumatoid arthritis: Results from a cross-sectional study

Objectives: The aim of this systematic review was to assess the oral-health-related quality of life (OHRQoL) of adult patients with rheumatic diseases. Material and Methods: A systematic literature search was performed, including clinical studies on adults (aged at least 18 years) with a verified diagnosis of rheumatic disease. Results: 26 out of 41 clinical studies including rheumatoid arthritis (RA, seven studies), systemic sclerosis (SSc, five), Sjogren syndrome (SS, eight), Behcet disease (BD, four), systemic lupus erythematosus (SLE, one) and ankylosing spondylitis (AS, one) were found. In 15 studies, a healthy control group was recruited. The short form of the Oral Health Impact Profile (OHIP 14) was most frequently applied. The majority of studies (14/15) reported worse OHRQoL in patients with rheumatic disease compared to healthy individuals. In particular, patients with SS (salivary flow and composition) or BD (oral ulcers) showed a relation between OHRQoL and disease-specific oral manifestations. Most studies investigating subscales of OHRQoL (5/6) found the subscale physical disability to be predominantly affected in patients with rheumatic diseases. About half of the studies reported impaired psychosocial aspects. Conclusion: Patients with rheumatic diseases exhibit reduced OHRQoL, especially in diseases with oral manifestations like SS and BD. Physical affections due to oral diseases and psychosocial impairments caused by disease-related parameters must be recognized within patient-centered dental care.

Oral-Health-Related Quality of Life in Adult Patients with Rheumatic Diseases-A Systematic Review.

The aim of this study was to evaluate the oral health-related quality of life (OHRQoL) in patients with rheumatoid arthritis (RA) depending on their oral health in comparison with healthy controls (HCs). One hundred three RA patients (55.5 years, female 58) were included. A healthy control group (HC n = 104; 56.7 years, female 68) was matched according to age, gender, and smoking habits. The OHRQoL was determined by Oral Health Impact Profile (OHIP)-G14 questionnaire. Oral examination included dental findings (DMF-T), gingival inflammation (PBI), periodontal probing depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BOP). Based on CAL and/or PPD, periodontitis was categorized as healthy/mild, moderate, or severe. Statistical analysis: trend test (Cochran-Armitage) and Wilcoxon rank-sum test (α = 5%). For DMF-T (RA 17.6 ± 6.1, HC 16.0 ± 6.5) and PBI (RA 0.10 ± 0.18, HC 0.08 ± 0.18), no significant differences between both groups were found (p > 0.05). Approximately 65% of RA group and 79% of HC group showed moderate to severe periodontitis (p = 0.02); RA patients showed significantly higher BOP values (p   0.05). RA patients showed a worse OHRQoL than HC patients, which was independent of dental and periodontal conditions. RA patients require a more intensive care in consideration of dental, medical, and psychological factors. Interdisciplinary collaboration between dentists and rheumatologists is necessary, whereby psychological factors should be considered.
