TL;DR: Increased loss of periodontal attachment and alveolar bone can be detected in patients with ERA, therefore it is proposed that the consulting rheumatologists inform the patients that they have a higher risk ofperiodontal disease.
Abstract: Objective. Patients with RA suffer from a higher risk of periodontal attachment loss and increased oral inflammation. We hypothesize that there are pathogenetic and immunological interactions between these diseases that go beyond impaired manual dexterity accompanying advanced RA. The primary objective of the present study was to determine whether a loss of alveolar bone can be detected in RA patients during the early course of the disease. Methods. In this cross-sectional, epidemiological casecontrol study, 22 patients with early RA (ERA) were compared with 22 matched healthy controls. Oral and periodontal status, clinical activity, and sociodemographic parameters were determined. Oral microbiota were analysed using real-time quantitative PCR specific for leading oral pathogens. Results. More advanced forms of periodontitis were found in ERA patients compared with controls. ERA patients had a greater number of missing teeth [ERA 5.7 (S.D. 5.0), controls 1.9 (S.D. 1.0), P = 0.002], deeper periodontal pockets [clinical attachment level: ERA 3.4 (S.D. 0.5 mm), controls 2.7 (S.D. 0.3 mm), P < 0.000], and greater bleeding on probing [ERA 18.6% (S.D. 9.0%), controls 10.5% (S.D. 5.1%), P = 0.001] despite comparable oral hygiene. Tannerella forsythia (6.77-fold, P = 0.033) subgingivally and Streptococcus anginosus (3.56-fold, P = 0.028) supragingivally were the characteristic pathogens in ERA. Conclusion. Increased loss of periodontal attachment and alveolar bone can be detected in patients with ERA, therefore we propose that the consulting rheumatologists inform the patients that they have a higher risk of periodontal disease. It would be beneficial if these patients were referred directly for intensive dental care.

TL;DR: Having IBS and being overweight, rather than IBS-subtypes, was the most important factor in describing the severity of visceral pain and variation in the microbiome, suggesting the potential of the oral microbiome in diagnosis and patient phenotyping.
Abstract: Irritable bowel syndrome (IBS) is a poorly understood disorder characterized by persistent symptoms, including visceral pain. Studies have demonstrated oral microbiome differences in inflammatory bowel diseases suggesting the potential of the oral microbiome in the study of non-oral conditions. In this exploratory study we examine whether differences exist in the oral microbiome of IBS participants and healthy controls, and whether the oral microbiome relates to symptom severity. The oral buccal mucosal microbiome of 38 participants was characterized using PhyloChip microarrays. The severity of visceral pain was assessed by orally administering a gastrointestinal test solution. Participants self-reported their induced visceral pain. Pain severity was highest in IBS participants (P = 0.0002), particularly IBS-overweight participants (P = 0.02), and was robustly correlated to the abundance of 60 OTUs, 4 genera, 5 families and 4 orders of bacteria (r2 > 0.4, P < 0.001). IBS-overweight participants showed decreased richness in the phylum Bacteroidetes (P = 0.007) and the genus Bacillus (P = 0.008). Analysis of β-diversity found significant separation of the IBS-overweight group (P < 0.05). Our oral microbial results are concordant with described fecal and colonic microbiome-IBS and -weight associations. Having IBS and being overweight, rather than IBS-subtypes, was the most important factor in describing the severity of visceral pain and variation in the microbiome. Pain severity was strongly correlated to the abundance of many taxa, suggesting the potential of the oral microbiome in diagnosis and patient phenotyping. The oral microbiome has potential as a source of microbial information in IBS.

TL;DR: This study was undertaken to investigate the association between elevated serum levels of IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults.
Abstract: Objective Alterations in the microbiome, including the periodontal microbiome, may be a risk factor for rheumatoid arthritis (RA). Most studies that have analyzed this association are relatively small, focus primarily on a single periodontal pathogen (Porphyromonas gingivalis), and are not population based. This study was undertaken to investigate the association between elevated serum levels of IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults. Methods The Third National Health and Nutrition Examination Survey (NHANES-III) is a cross-sectional sample of the noninstitutionalized US population (n = 33,994). Our study population included all dentate participants who were 60 years and older, did not have RA as defined by a modified version of the American College of Rheumatology 1987 criteria, and had complete data for both serum IgG antibodies against periodontal bacteria and serum RF antibody titer (n = 2,461). Results Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) summarizing the relationship between the 19 periodontal serum IgG antibodies and RF seropositivity ranged from 0.53 (95% CI 0.29–0.97) to 1.27 (95% CI 0.79–2.06), and 17 of the 19 observed ORs were <1.0. The ORs for RF seropositivity among participants with elevated Prevotella intermedia (0.53 [95% CI 0.29–0.97]) and Capnocytophaga ochracea (0.54 [0.31–0.95]) IgG levels were statistically significant. Conclusion Our findings indicate that elevated levels of IgG antibodies to periodontal bacteria are mostly unassociated with RF seropositivity in the nationally representative NHANES-III. Elevated levels of antibodies to P intermedia and C ochracea are associated with lower odds of RF seropositivity.

TL;DR: Rheumatoid arthritis medication is associated with periodontal inflammation, without differences inperiodontal disease severity, and combination of MTX + TNF-α shows an increased potential to periodontAL inflammation.
Abstract: 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.

TL;DR: A better understanding of the pre-RA stage will be useful in developing screening programs for early detection of RA and identifying and modifying risk factors such as smoking, periodontitis, obesity, viral infections, and hormonal or dietary factors will be helpful in preventing RA in susceptible population.
Abstract: Pre-rheumatoid arthritis (pre-RA) is the preclinical period of the disease that precedes the onset of clinically apparent RA. It includes the interaction between genetic and environmental risk factors and development of disease-related autoantibodies and joint symptoms and signs, which may be considered nonspecific or unclassified for RA. A better understanding of the pre-RA stage will be useful in developing screening programs for early detection of RA. Identifying and modifying risk factors such as smoking, periodontitis, obesity, viral infections, and hormonal or dietary factors will be useful in preventing RA in susceptible population.

TL;DR: RA patients showed a worse OHRQoL than HC patients, which was independent of dental and periodontal conditions, and interdisciplinary collaboration between dentists and rheumatologists is necessary.
Abstract: 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.

TL;DR: This new classification system redefines the current paradigm of RA by focusing on features at earlier stages of disease that are associated with persistent and/or erosive disease, rather than defining the disease by its late-stage features.
Abstract: Objective The 1987 American College of Rheumatology (ACR; formerly the American Rheumatism Association) classification criteria for rheumatoid arthritis (RA) have been criticised for their lack of sensitivity in early disease. This work was undertaken to develop new classification criteria for RA. Methods A joint working group from the ACR and the European League Against Rheumatism developed, in three phases, a new approach to classifying RA. The work focused on identifying, among patients newly presenting with undifferentiated inflammatory synovitis, factors that best discriminated between those who were and those who were not at high risk for persistent and/or erosive disease—this being the appropriate current paradigm underlying the disease construct ‘RA’. Results In the new criteria set, classification as ‘definite RA’ is based on the confirmed presence of synovitis in at least one joint, absence of an alternative diagnosis better explaining the synovitis, and achievement of a total score of 6 or greater (of a possible 10) from the individual scores in four domains: number and site of involved joints (range 0–5), serological abnormality (range 0–3), elevated acute-phase response (range 0–1) and symptom duration (two levels; range 0–1). Conclusion This new classification system redefines the current paradigm of RA by focusing on features at earlier stages of disease that are associated with persistent and/or erosive disease, rather than defining the disease by its late-stage features. This will refocus attention on the important need for earlier diagnosis and institution of effective disease-suppressing therapy to prevent or minimise the occurrence of the undesirable sequelae that currently comprise the paradigm underlying the disease construct ‘RA’.

TL;DR: How the new classification for periodontal diseases and conditions presented in this volume differs from the classification system developed at the 1989 World Workshop in Clinical Periodontics is summarized.
Abstract: Classification systems are necessary in order to provide a framework in which to scientifically study the etiology, pathogenesis, and treatment of diseases in an orderly fashion. In addition, such systems give clinicians a way to organize the health care needs of their patients. The last time scientists and clinicians in the field of periodontology and related areas agreed upon a classi- fication system for periodontal diseases was in 1989 at the World Workshop in Clinical Periodontics.1 Subsequently, a simpler classification was agreed upon at the 1st European Workshop in Periodontology.2 These classification systems have been widely used by clinicians and research scientists throughout the world. Unfortunately, the 1989 classification had many shortcomings including: 1) considerable overlap in disease categories, 2) absence of a gingival disease component, 3) inappropriate emphasis on age of onset of disease and rates of progression, and 4) inadequate or unclear classification criteria. The 1993 Europea...

TL;DR: The purpose of the present investigation was to attempt to define communities using data from large numbers of plaque samples and different clustering and ordination techniques, which related strikingly to clinical measures of periodontal disease particularly pocket depth and bleeding on probing.
Abstract: It has been recognized for some time that bacterial species exist in complexes in subgingival plaque. The purpose of the present investigation was to attempt to define such communities using data from large numbers of plaque samples and different clustering and ordination techniques. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 +/- 16 years) with (n = 160) or without (n = 25) periodontitis. The presence and levels of 40 subgingival taxa were determined in 13,261 plaque samples using whole genomic DNA probes and checkerboard DNA-DNA hybridization. Clinical assessments were made at 6 sites per tooth at each visit. Similarities between pairs of species were computed using phi coefficients and species clustered using an averaged unweighted linkage sort. Community ordination was performed using principal components analysis and correspondence analysis. 5 major complexes were consistently observed using any of the analytical methods. One complex consisted of the tightly related group: Bacteroides forsythus, Porphyromonas gingivalis and Treponema denticola. The 2nd complex consisted of a tightly related core group including members of the Fusobacterium nucleatum/periodonticum subspecies, Prevotella intermedia, Prevotella nigrescens and Peptostreptococcus micros. Species associated with this group included: Eubacterium nodatum, Campylobacter rectus, Campylobacter showae, Streptococcus constellatus and Campylobacter gracilis. The 3rd complex consisted of Streptococcus sanguis, S. oralis, S. mitis, S. gordonii and S. intermedius. The 4th complex was comprised of 3 Capnocytophaga species, Campylobacter concisus, Eikenella corrodens and Actinobacillus actinomycetemcomitans serotype a. The 5th complex consisted of Veillonella parvula and Actinomyces odontolyticus. A. actinomycetemcomitans serotype b, Selenomonas noxia and Actinomyces naeslundii genospecies 2 (A. viscosus) were outliers with little relation to each other and the 5 major complexes. The 1st complex related strikingly to clinical measures of periodontal disease particularly pocket depth and bleeding on probing.

TL;DR: Examination systems for oral hygiene status use either selected teeth or the highest score for a group of teeth within a segment as the basis for their scores, which are of limited value for the clinician treating an individual patient.
Abstract: A N U M B E R OF examination systems have been developed to record the oral hygiene status of an individual. Most systems use either selected teeth or the highest score for a group of teeth within a segment as the basis for their scores. When used for epidemiological studies or for evaluating the results of treatment in a study group these methods yield useful information. A numerical score, however, is of limited value for the clinician treating an individual patient. He is concerned with the locations where plaque accumulates and in the patient's progress in learning how to effectively clean these surfaces.
