Risk association between scleroderma disease characteristics, periodontitis, and tooth loss

Evaluation of oral health in 148 patients with systemic sclerosis-data from a prospective interdisciplinary monocentric cohort

In daily rheumatology practice, systemic sclerosis is primarily regarded as a potentially life-threatening disease characterized by fibrosis of various organs. Therefore, other manifestations, such as orofacial involvement, are often not of primary concern. Furthermore, due to its rarity, the disease might not be well known by dentists, which contrasts with the increased risk of various problems in the oral cavity. Periodontitis in particular is a known risk factor for morbidity and mortality and is associated with various systemic diseases. The risk of periodontitis appears to be increased in patients with systemic sclerosis, but little is known about the gender-specific differences. This study aims to elucidate the health-conscious behaviour of patients, their dental care and the risk of periodontitis with regard to gender-specific differences. This descriptive study of the Interdisciplinary Centre of Rheumatic Diseases (INDIRA) in collaboration with the Department of Orthodontics at the University Hospital of Tuebingen, Germany, examined the data of 148 patients with systemic sclerosis with regard to their oral health using a questionnaire and evaluating the risk of periodontitis with the DG Paro self-assessment score in this cohort. Among the participating patients, 90% reported regular visits to the dentist and good dental care. Nevertheless, more than half of the patients had missing teeth and problems opening their mouths. Sicca symptoms in the oral cavity were also common (40%). The risk of periodontitis among female participants was high (around 60%), and even higher among male study participants (around 80%). Gingival bleeding as a surrogate parameter for periodontitis was associated with salivary flow and the modified Rodnan skin score (mRSS). Despite a high awareness of dental health, we observed a high risk of periodontitis, especially in male patients with systemic sclerosis. In addition, the association between xerostomia and missing teeth as well as gingival bleeding and mRSS may indicate an increased risk in patients with a more progressive disease. We would therefore recommend regular dental consultations and careful oral hygiene for patients with systemic sclerosis in addition to the-more organ-focused-regular examinations of patients.

Insights into the Relationship between Periodontitis and Systemic Sclerosis Based on the New Periodontitis Classification (2018): A Cross-Sectional Study

(1) Background: This study aimed to assess the periodontitis burden in systemic sclerosis patients and the possible association between them, and the degree to which some potential risk factors and two potential diagnostic biomarkers may account for this association. (2) Methods: This cross-sectional study included a test group (systemic sclerosis patients) and a control group (non-systemic sclerosis patients). Both groups benefited from medical, periodontal examination and saliva sampling to determine the salivary flow rate and two inflammatory biomarkers (calprotectin, psoriasin). A systemic sclerosis severity scale was established. (3) Results: In the studied groups, comparable periodontitis rates of 88.68% and 85.85%, respectively, were identified. There were no significant differences in the severity of periodontitis among different systemic sclerosis severity, or in the positivity for anti-centromere and anti-SCL70 antibodies. Musculoskeletal lesions were significantly more common in stage III/IV periodontitis (n = 33, 86.84%) than in those in stage I/II (n = 1, 100%, and n = 3, 37.5%, respectively) (p = 0.007). Comparable levels of the inflammatory mediators were displayed by the two groups. There were no significant differences in calprotectin and psoriasin levels between diffuse and limited forms of systemic sclerosis. (4) Conclusions: Within the limitations of the current study, no associations between systemic sclerosis and periodontitis, or between their risk factors, could be proven.

Orofacial Manifestation of Systemic Sclerosis: A Cross-Sectional Study and Future Prospects of Oral Capillaroscopy

BACKGROUND AND OBJECTIVES

oral alterations in Systemic Sclerosis (SSc) patients are widespread and include microstomia, periodontitis, telangiectasias, mandibular resorption, bone lesions, and xerostomia. This cross-sectional study aims to evaluate the differences between SSc patients (cases) and healthy subjects (controls) regarding oral manifestations, quality of life (QoL), and microcirculation alterations.

METHODS

plaque index (PCR), periodontal index (PSR), DMFT, salivary flow rate, and buccal opening were measured by expert clinicians. S-HAQ test, the Self-Rating Anxiety State (SAS), the Self-Rating Depression Scale (SDS), and the WHOQOL-BREF test were administered to patients to evaluate their QoL. Microvascular alterations were assessed by oral videocapillaroscopy, performed on gingival and labial mucosa. A statistical analysis was conducted to find significant differences between healthy people and SSc patients.

RESULTS

59 patients were enrolled in this study. Standard salivary flow is significantly more frequent in controls, while xerostomia, reduced flow, microstomia, lip retraction, and periodontitis are significantly more frequent in the cases. Gingival capillaroscopy showed differences concerning loop visibility, thickening of the gum, tortuosity of gingival loops, and reduced gingival density. Labial capillaroscopy demonstrates that visibility of the labial loops, the labial ectasias, and the tortuosity of the loops are significantly associated with the presence of scleroderma. Hand and facial deformities, hypomobility of the tongue, cheeks, lips, microstomia, and xerostomia significantly compromised the quality of life of SSc patients, which was significantly worse among them. Moreover, oral videocapillaroscopy could be a proper diagnostic method to detect oral microcirculation alterations. SSc patients often present ectasias, rarefaction of the reticulum, microhemorrhages, and megacapillaries, which negatively impact their oral health.

CONCLUSIONS

periodontitis, reduced salivary flow, and microstomia could be considered SSc oral manifestations. Joint deformities, facial appearance, and comorbidities significantly reduce the QoL of SSc patients compared to healthy subjects. Oral videocapillaroscopy could be an innovative and reliable technique to detect oral microcirculation anomalies.

Periodontal health status in systemic sclerosis patients: Systematic review and meta-analysis

OBJECTIVE

The present systematic review and meta-analysis aimed to evaluate the periodontal health of systemic sclerosis patients compared with non-systemic sclerosis controls.

MATERIALS AND METHODS

Online databases were searched for eligible studies on February 24, 2023. The primary outcomes of interest in systemic sclerosis patients and controls included the clinical attachment level, periodontal probing depth, recession depth, plaque index, bleeding on probing score, gingival index, number of teeth with periodontitis, prevalence of periodontitis and gingivitis, and extent and severity of periodontitis.

RESULTS

Fourteen studies met inclusion criteria and were incorporated in the qualitative and quantitative analysis. In comparison with the controls, systemic sclerosis patients had a higher prevalence of periodontitis (OR = 7.63 (1.74-33.50), p = 0.04, I2 = 69%), including more severe forms of periodontitis (OR = 6.68 (3.39-13.15), p = 0.85, I2 = 0%), as well as higher periodontal probing depth ((0.88 (0.45-1.31), p = 0.02, I2 = 99%)), clinical attachment level (1.22 (0.8-1.64), p = 0.003, I2 = 98%), and plaque presence (0.83 (0.13-1.53), p = 0.03, I2 = 96%). There was no statistically significant difference in gingival inflammation (1.14 (0.07-2.21), p = 0.04, I2 = 98%).

CONCLUSIONS

The systematic review and the meta-analysis showed that systemic sclerosis patients suffer from worse periodontal health than non-systemic sclerosis individuals.

High prevalence and risk factors for osteoporosis in 1839 patients with systemic sclerosis: a systematic review and meta-analysis

OBJECTIVES

Osteoporosis is prevalent in patients with systemic sclerosis (SSc). Updated evidence is required to complement the previous systematic review on this topic to provide best practices. This systematic review and meta-analysis aimed to quantitatively synthesize data from studies concerning the prevalence and risk factors for osteoporosis among patients with SSc.

METHODS

We searched PubMed, EMBASE, Web of Science, and ScienceDirect databases for potential studies published from inception to May 31, 2022. Eligibility screening, data extraction, and quality assessment of the retrieved articles were conducted independently by two reviewers. Then meta-analyses were performed to determine osteoporosis prevalence and risk factors in patients with SSc. Meta-regression analysis was conducted to explore the sources of heterogeneity.

RESULTS

The pooled prevalence of osteoporosis in patients with SSc was 27% (95% CI, 24-31), with moderate heterogeneity (I² = 61.6%). Meta-regression revealed no significant difference among all variables. And the presence of SSc increased the likelihood of having osteoporosis (OR = 3.05, 95% CI, 2.32-4.01) compared to controls. These significant risk factors for osteoporosis in SSc patients were age > 50 years (OR = 2.94, 95% CI, 1.52-5.68), menopause (OR = 3.90; 95% CI, 1.94-7.84), aging (MD = 8.40; 95% CI,6.10-10.71) and longer disease duration (MD = 4.78; 95% CI,1.83-7.73). However, female (OR = 1.45; 95% CI, 0.75-2.77), pulmonary arterial hypertension (OR = 0.50; 95% CI, 0.17-1.54), and diffuse cutaneous SSc (OR = 1.05; 95% CI, 0.75-1.48) were not significant risk factors for osteoporosis in SSc patients.

CONCLUSIONS

Osteoporosis was highly prevalent in patients with SSc, and the prevalence seemed to be high and similar in many countries. The age > 50 years, menopause, aging, and longer disease duration were identified as risk factors for osteoporosis in patients with SSc.

Current Perspectives on Periodontitis in Systemic Sclerosis: Associative Relationships, Pathogenic Links, and Best Practices

Systemic sclerosis is a chronic, autoimmune, multisystemic disease characterized by aberrant extracellular matrix protein deposition and extreme progressive microvasculopathy. These processes lead to damage within the skin, lungs, or gastrointestinal tract, but also to facial changes with physiognomic and functional alterations, and dental and periodontal lesions. Orofacial manifestations are common in SSc but are frequently overshadowed by systemic complications. In clinical practice, oral manifestations of SSc are suboptimally addressed, while their management is not included in the general treatment recommendations. Periodontitis is associated with autoimmune-mediated systemic diseases, including systemic sclerosis. In periodontitis, the microbial subgingival biofilm induces host-mediated inflammation with subsequent tissue damage, periodontal attachment, and bone loss. When these diseases coexist, patients experience additive damage, increasing malnutrition, and morbidity. The present review discusses the links between SSc and periodontitis, and provides a clinical guide for preventive and therapeutical approaches in the management of these patients.

Salivary Antioxidant Profile in Patients with Systemic Sclerosis and Periodontitis

Objective

The aim of the present study was to compare periodontal status and antioxidant profile in unstimulated saliva of systemic sclerosis (SSc) patients with periodontitis and systemically healthy periodontitis patients.

Design

Twenty patients with established diagnoses of systemic sclerosis and periodontitis (SSc group) and 20 systemically healthy individuals with periodontitis (P group) were enrolled in the study. Clinical periodontal parameters (clinical attachment level (CAL), gingival recession (GR), periodontal probing depth (PPD), and gingival index (GI)) and concentration of uric acid (UA), superoxide dismutase (SOD), and glutathione peroxidase (GPX) in unstimulated saliva samples were assessed.

Results

There were significantly higher mean values of CAL (4.8 ± 0.21 mm versus 3.18 ± 0.17 mm; p ≤ 0.001) and GR (1.66 ± 0.90 mm versus 0.46 ± 0.54 mm; p ≤ 0.001) in the SSc group when compared to the P group. Significantly higher level of GPX (p ≤ 0.001) and SOD (p ≤ 0.001) in unstimulated saliva was detected in the SSc group in comparison with the P group. The specific activity of UA did not significantly differ between the two groups (p = 0.083).

Conclusion

The results may indicate higher periodontal destruction and antioxidant perturbations in unstimulated saliva of SSc patients with periodontitis compared to systemically healthy periodontitis patients.

Diet in Scleroderma: Is There a Need for Intervention?

Systemic sclerosis (SSc) patients exhibit a plethora of risk factors for nutritional decline, including the presence of chronic inflammation and the progressive nature of disease-related multisystem involvement. The prevalence and consequences of nutritional decline in scleroderma are frequently underestimated, its management currently remaining a subject of debate. The main objective of the present study was to perform a detailed assessment of scleroderma patients' diet as well as their eating habits and to describe the relationships with weight loss and malnutrition risk in the absence of professional nutritional counseling.

METHODS

We used a translated and validated version of the EPIC-Norfolk FFQ (European Prospective Investigation into Cancer and Nutrition Norfolk Food Frequency Questionnaire) to evaluate the patients' diet and MUST (Malnutrition Universal Screening Tool) to investigate the risk of malnutrition. Disease activity was estimated using the EUSTAR-AI (European Scleroderma Trials and Research group Activity Index).

RESULTS

We included 69 patients with SSc, of which 42 underwent a detailed dietary assessment. Dietary factors were connected to body composition and digestive symptoms. We found high sodium intake and frequent suboptimal energy consumption in our study group, including patients with cardiopulmonary involvement. Liver transaminases were inversely correlated with the consumption of nuts and seeds. Malnutrition and weight loss were significantly associated with pulmonary hypertension, heart failure, albumin levels, and the extent of skin fibrosis, but not advanced age. Although the patients with EUSTAR-AI ≥ 2.5 were more frequently included in the moderate and high malnutrition risk categories, these results did not reach statistical significance.

CONCLUSIONS

Currently, there is an unmet need for longitudinal and interventional research focusing on the long-term significance, ramifications, and management of nutritional impairment in SSc patients with various clinical manifestations. Our results indicate that scleroderma patients could benefit from personalized nutritional counseling in an interdisciplinary setting.

Influence of Gestational Hormones on the Bacteria-Induced Cytokine Response in Periodontitis

Periodontitis is an inflammatory disease that affects the supporting structures of teeth. The presence of a bacterial biofilm initiates a destructive inflammatory process orchestrated by various inflammatory mediators, most notably proinflammatory cytokines, which are upregulated in the gingival crevicular fluid, leading to the formation of periodontal pockets. This represents a well-characterized microbial change during the transition from periodontal health to periodontitis; interestingly, the gestational condition increases the risk and severity of periodontal disease. Although the influence of periodontitis on pregnancy has been extensively reviewed, the relationship between pregnancy and the development/evolution of periodontitis has been little studied compared to the effect of periodontitis on adverse pregnancy outcomes. This review is aimed at summarizing the findings on the pregnancy-proinflammatory cytokine relationship and discussing its possible involvement in the development of periodontitis. We address (1) an overview of periodontal disease, (2) the immune response and possible involvement of proinflammatory cytokines in the development of periodontitis, (3) how bone tissue remodelling takes place with an emphasis on the involvement of the inflammatory response and metalloproteinases during periodontitis, and (4) the influence of hormonal profile during pregnancy on the development of periodontitis. Finally, we believe this review may be helpful for designing immunotherapies based on the stage of pregnancy to control the severity and pathology of periodontal disease.

Investigation of the Expression of Inflammatory Markers in Oral Biofilm Samples in Patients with Systemic Scleroderma and the Association with Clinical Periodontal Parameters-A Preliminary Study

BACKGROUND

Systemic scleroderma (SSc) has multiple orofacial effects. The aim of this study was to analyze the expression of inflammatory mediators in biofilm samples. It was hypothesized that different expression levels and clinical associations might be drawn.

METHODS

A total of 39 biofilm samples from group 1 = SSc and group 2 = healthy control were examined for the expression levels of interleukin (IL)-2,-6, and -10; matrix metalloprotease (MMP)-9; and surface antigens CD90 and CD34 by quantitative real-time PCR and clinical parameters. Relative quantitative (RQ) gene expression was determined using the ∆∆CT method.

RESULTS

The mean bleeding on probing values (p = 0.006), clinical attachment loss (CAL) (p = 0.009), gingival recession (p = 0.020), limited mouth opening (p = 0.001) and cervical tooth defects (p = 0.011) were significantly higher in group 1. RQ expressions of IL-2 and CD34 were significantly lower, IL-6, MMP-9, and CD90 were significantly higher. There was a significant positive correlation of IL-6/MMP-9 and negative correlation of mouth opening/CAL and IL-6/CAL.

CONCLUSION

Different expression levels of IL-2, IL-6, MMP-9, CD34 and CD90 were detected in biofilm samples from patients with SSc compared to control. An immunological correlation to the clinical parameters of mouth opening and CAL was shown; thus, we conclude that SSc might have an impact on periodontal tissues.

Digestive Dysbiosis in Systemic Scleroderma: a Review

Systemic sclerosis (SSc) is a rare autoimmune disease characterized by widespread microvasculopathy, inflammation, and fibrosis of the skin and internal organs. The involvement of the gastrointestinal tract is associated with a wide variety of symptoms and affects circa 90% of patients during the course of the disease. The gastrointestinal microbiota contains trillions of microbial cells and has been found to contribute to both local and systemic homeostasis. In both health and disease, a dynamic interrelationship between gut microbiome activity and the host immune system has been identified. Gastrointestinal dysbiosis has been described as having an important role in obesity, diabetes mellitus, liver disease, cardiovascular and neuropsychiatric disorders, neoplasia, as well as autoimmunity. Recent scientific data indicates a notable role of dysbiosis in the pathogenesis of SSc-related digestive involvement together with various other clinical manifestations. The present review aims to summarize the recent findings regarding digestive dysbiosis as well as the relationship between gastrointestinal microbiota and certain features of SSc.

Endocan and Circulating Progenitor Cells in Women with Systemic Sclerosis: Association with Inflammation and Pulmonary Hypertension

Background: Systemic sclerosis (SSc) is characterized by early vasculopathy and fibrosis in the skin, lungs, and other tissues. Vascular manifestations of SSc include Raynaud’s phenomenon, digital ulcers, and pulmonary artery hypertension (PAH). PAH is the second most common cause of mortality in SSc. Circulating CD34+ cells associated with cardiovascular health status in several conditions, including chronic immune-inflammatory disease. CD34+ cell numbers have been found inconstantly reduced in SSc. Endocan, a proteoglycan expressed by endothelial cells, was recently suggested as a marker of vascular stress. We tested the relationships among CD34+ cells, endocan, inflammatory markers, vitamin D levels, and clinical parameters in SSc patients with PAH. METHODS: Standard echocardiography was performed. Vitamin D levels, CD34+ cells, inflammatory markers, endocan plasma levels were determined in 36 female SSc patients (24 diffuse/12 limited) and 36 matched controls (HC). RESULTS: We found no difference in CD34+ and vitamin D levels in SSc as compared to controls; ESR, CRP, fibrinogen, endocan, sPAP were higher in SSc with respect to controls. We found a correlation between endocan and: CD34+ cells (r: −0.540, p = 0.002), pulmonary arterial pressure (sPAP) (r: 0.565, p < 0.001), tricuspid annular plane excursion (TAPSE) (r: −0.311, p < 0.01), and E/A ratio (r: −0.487, p < 0.001), but not with ejection fraction (r: −0.057, p = 0.785) in SSc. CD34+ cells correlate with fibrinogen (r: −0.619, p < 0.001), sPAP (r: −0.404, p = 0.011), E/A (r: 0.470, p < 0.005 in SSc. CONCLUSION: CD34+ cell number was significantly correlated with endocan levels and with sPAP in SSc; endocan and CD34+ progenitor cells might be suggested as a potential marker of disease status.

Oral manifestations of patients with systemic sclerosis: a meta-analysis for case-controlled studies

Background

Systemic sclerosis (SSc) is a multisystem rheumatic disease. Orofacial manifestations are commonly in SSc but maybe usually ignored and overshadowed by other systemic complications. Multiple comparative studies have been conducted to investigate the possible links between SSc and oral manifestations. The present study aimed to investigate the oral health status in patients with SSc.

Methods

Pubmed, Embase, Web of Science, and Scopus were searched up to July 2020. Following outcomes were evaluated: Probing depth (PD), Attachment loss (AL), Bleeding on probing (BOP), Number or percentage of Sites with PD ≥ 4 mm, Prevalence of periodontitis, Number of teeth, Decayed Teeth, Missing teeth, Filled teeth, DMFT index, and the interincisal distance. Newcastle-Ottawa Scale (NOS) were applied for quality assessment. The statistical analysis was processed using the software STATA.

Results

11 eligible studies were included. The maximum interincisor distance was significantly restricted in SSc patients (SMD − 1.061; 95 %CI [− 1.546, − 0.576]; Z = 4.29, P = 0.000).The prevalence of Periodontitis (OR 7.007; 95 %CI [3.529, 13.915]; Z = 5.56, P = 0.000), PD (SMD 3.101; 95 %CI [1.374, 4.829]; Z = 3.52, P = 0.000), AL(SMD 2.584; 95 %CI [0.321, 4.846]; Z = 2.24, P = 0.025), sites with PD ≥ 4mm (SMD 2.071 ; 95 %CI [0.267, 3.875]; Z = 2.25, P = 0.024) and the number of decayed teeth (SMD, 0.186; 95 %CI [0.007, 0.365]; Z = 2.04, P = 0.041) were increased significantly in SSc population in comparison with the controls.

Conclusions

SSc patients have limited mouth opening, higher periodontitis prevalence, and worse periodontal status, as well as an increased number of decayed teeth. Routinely oral hygiene instruction and initial periodontal treatment is recommended for SSc patients.

Implant-based oral rehabilitation in systemic sclerosis patients: a systematic review

Systemic sclerosis is a rare multisystem autoimmune disorder that significantly impacts the orofacial region. Several oral features including microstomia and increased tooth loss contribute to the mouth-related disability. Prosthetic rehabilitation is very challenging in these patients. As the spectrum of dental implants indications has been recently extended to patients with various systemic disorders, the aim of this systematic review was to evaluate the outcome of dental implants in patients with systemic sclerosis. A literature search was conducted in Medline/PubMed database to identify eligible case-reports. 10 publications were included in qualitative synthesis. A total of 71 implants have been reported in 10 patients with systemic sclerosis with a mean of 7.1 +/- 3.8 implants per patient. Pre-implant surgeries have been described for 3 patients. Implant survival rates were higher than 98% but the mean follow-up time was only 28.3 +/- 18.6 months. Complications have been observed in 3 patients with 1 implant failure and peri-implant bone resorption in 2 patients. Although implant survival rates were high, an individualized assessment of risk-benefit balance is mandatory before indicating implant-based rehabilitation in patients suffering from systemic sclerosis and a scrupulous maintenance program has to be implemented. Further studies are strongly required to establish clinical guidelines.

Association of Systemic Sclerosis and Periodontitis with Vitamin D Levels

The aim of the present study was to analyze the association among systemic sclerosis (SSc), periodontitis (PT); we also evaluated the impact of PT and SSc on vitamin D levels. Moreover, we tested the association with potential confounders. A total of 38 patients with SSc, 40 subjects with PT, 41 subjects with both PT and SSc, and 41 healthy controls were included in the study. The median vitamin D levels in PT subject were 19.1 (17.6-26.8) ng/mL, while SSc + PT group had vitamin d levels of 15.9 (14.7-16.9) ng/mL, significantly lower with respect to SSc patients (21.1 (15.4-22.9) ng/mL) and to healthy subjects (30.5 (28.8-32.3) ng/mL) (p < 0.001). In all subjects, vitamin D was negatively associated with c-reactive protein (CRP) (p < 0.001) and with probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque score (PI) (p < 0.001 for all parameters) and positively related to the number of teeth (p < 0.001). Moreover, univariate regression analysis demonstrated an association among high low-density lipoproteins (LDL) cholesterol (p = 0.021), CRP (p = 0.014), and PT (p < 0.001) and reduced levels of vitamin D. The multivariate regression analysis showed that PT (p = 0.011) and CRP (p = 0.031) were both predictors of vitamin D levels. Subjects with PT and SSc plus PT had significant lower vitamin D values with respect to SSc and to healthy subjects. In addition, PT seems negatively associated with levels of vitamin D in all analyzed patients.

Systemic sclerosis: Update for oral health care providers

Systemic sclerosis (SSc), also known as scleroderma, is an autoimmune disease of unknown origin characterized by an uncontrolled inflammatory process resulting in fibrosis of the skin, internal organs and vasculopathy. Manifestations of SSc are heterogenous and can include pulmonary, cardiac, neural, renal, muscular, cutaneous and orofacial complications. Recent scientific advances have led to a better understanding of disease etiopathogenesis and the development of a new classification system. Therapeutic management is often multidisciplinary and targeted toward the affected organs. Oral health care providers (OHCPs) should be familiar with SSc, particularly as it relates to its impact on the orofacial region and modifications to delivery of oral health care for patients with this condition.

Clinical Assessment of Gastrointestinal Involvement in Patients with Systemic Sclerosis

Systemic sclerosis (SSc) has the potential to affect any component of the gastrointestinal (GI) tract. GI involvement in SSc is a leading cause of morbidity and overall decreased quality of life in this patient population, identifying a need for a concise approach to work-up. This literature review aims to present a systematic, anatomical approach and differential diagnosis of GI involvement in SSc for the general internist and rheumatologist. Each component of the luminal GI tract has its own specified section, beginning with a review of a clinical approach to diagnosis that includes a differential for clinicians to consider, followed by a discussion of the literature surrounding objective evaluation of these conditions (i.e. serologic studies, imaging, endoscopy). Additionally there is a focused discussion on an approach to GI bleeding in the patient with SSc.

Reduced salivary flow and caries status are correlated with disease activity and severity in patients with diffuse cutaneous systemic sclerosis

Objective

To analyze the correlations of saliva production and pH value with disease activity, disease severity, and oral health-related quality of life in patients with diffuse cutaneous systemic sclerosis (dcSSc) without concomitant Sjögren’s syndrome (SS) or SS-related antibodies.

Methods

This cross-sectional study included 28 patients with dcSSc and matching healthy controls. Sialometric assessment and caries status were compared between the two groups. Clinical and laboratory parameters were used to evaluate disease severity, in accordance with the Medsger Severity Scale.

Results

In patients with dsSSc, reduced saliva production and higher pH value were associated with disease activity and severity; moreover, caries status was correlated with SSc disease characteristics, including disease duration and disease severity. Oral health-related quality of life was negatively correlated with mean salivary flow rate.

Conclusions

These findings contradict the existing notion that reduced saliva production in patients with SSc is linked to SS-related antibodies or caused by underlying SS. In addition, patients with dcSSc exhibit elevated risk of cardiovascular disease and invasive dental treatment has been shown to enhance the rates of stroke and heart attack in the general population; therefore, oral health is particularly important in patients with SSc.

Etiology and characteristics of halitosis in patients of a halitosis center in Northern Italy

BACKGROUND

As there are few studies in Europe describing characteristics of breath malodor for large groups of patients, this retrospective study was designed to analyse the etiology of halitosis among patients attending a breath malodor center in Northern Italy.

METHODS

Clinical records of 547 consecutive patients were reviewed and data on self-perceived halitosis, organoleptic scores, volatile sulphur compound (VSC) levels, and oral health condition were extracted and analysed.

RESULTS

The prevalence of intra-oral halitosis was 90.7%. In 21 patients no objective signs of breath malodor could be found. Periodontitis and gingivitis were the main cause of bad breath in 33.9% of subjects and in combination with tongue coating in 55.2%. Only eight subjects have tongue coating as the only cause of halitosis. Ear, nose and throat (ENT)/extra-oral causes were found in 5.2% of the patients. VSC concentrations were lower in the psychogenic halitosis group, whereas no statistically significant differences were detected when comparing intra-oral and extra-oral halitosis except for (CH3)2S.

CONCLUSIONS

Psychogenic halitosis is a rare condition among subjects complaining of suffering from bad breath. The most prevalent cause of halitosis is intra-oral, in particular a combination of tongue coating and periodontal disease. Tongue coating is rarely the primary cause of oral malodor.

A Full Diagnostic Process for the Orthodontic Treatment Strategy: A Documented Case Report

The need for extractions in orthodontic treatment has always been a controversial topic. However, to date there is not a specific clinical guideline that can help the clinicians deciding to plan an extractive or a non-extractive orthodontic treatment. In this respect, clinicians must deal with patients’ occlusal, functional, periodontal and aesthetics characteristics before planning an orthodontic treatment including extraction. Considering the absence of specific guidelines, the choice to extract teeth or not is complicated, particularly in borderline cases. In this case report, we present a borderline case of a patient with the skeletal Class III pattern and significant crowding in both arches that could be treated with or without extraction, illustrating the diagnostic and decision-making processes that were conducted for the orthodontic treatment strategy.

The Efficacy of Retention Appliances after Fixed Orthodontic Treatment: A Systematic Review and Meta-Analysis

The purpose of this article is to evaluate the amount of the relapse of anterior crowding and the efficacy of retention appliances by reviewing the best available scientific evidence. A survey of articles published up to November 2019 about the stability of dental alignment and retention after fixed orthodontic treatment was performed using seven electronic databases. Study Selection: Only randomized clinical trials investigating patients previously treated with multi-bracket appliances with a follow-up period longer than 6 months were included. Data Extraction: Two authors independently performed the study selection, data extraction, and risk of bias assessment. All pooled data analyses were performed using a random-effects model. Statistical heterogeneity was evaluated. In total, eight randomized clinical trials (RCTs) were included, grouping data from 987 patients. The ages of the patients varied across the studies, ranging between 13 and 17 years. The observation period ranged between 6 and 24 months. The data showed no significant intercanine width modifications during the retention period with both fixed and removable retainers. A significant modification of Little’s Index was found for the mandibular removable retainers with a mean difference of 0.72 mm (95% Cl, 0.47 to 0.98) and for the maxillary removable retainers with a mean difference of 0.48 mm (95% Cl, 0.27 to 0.68). No significant changes were found by evaluating Little’s Index modification for the mandibular fixed retainers. The results of this meta-analysis showed that all the considered retainers were effective in maintaining dental alignment after fixed orthodontic treatment. However, fixed retainers showed greater efficacy compared to removable retainers.

A Comparative Assessment of Pain Caused by the Placement of Banded Orthodontic Appliances with and without Low-Level Laser Therapy: A Randomized Controlled Prospective Study

Patients still refuse or discontinue orthodontic treatment due to related pain and discomfort. In this study, we investigate if low-level laser therapy (LLLT) can reduce pain caused by orthodontic bands. Sixty subjects who needed bands placed on the upper permanent first molars were assigned randomly to the LLLT group, placebo, and control groups. Inclusion criteria were: age range 10–14 years, fully erupted upper first molars in healthy condition, presence of tight mesial proximal contact. Exclusion criteria were: systemic or metabolic diseases, chronic pain or neurological or psychiatric disorders, use of pharmacological agents interfering with pain perception, previous orthodontic treatment or the simultaneous presence of other devices in the patient’s mouth. The assessment of pain was performed by using a numeric rating scale (NRS) considering different time intervals, i.e., immediately after bands placement, 6 h, 24 h, and from day 2 to day 5. Differences in the maximum pain and in pain experienced at each time-point, among the three groups, was assessed by using the Kruskal–Wallis H. The final sample included 56 patients, 29 males, and 27 females, with a mean age of 12.03 ± 1.3 years. Patients were randomly allocated into three groups (tested, control, and placebo group) with each group consisting respectively of 19, 20, and 17 individuals. Subjects in the LLLT experienced less pain at each time interval as well as the maximum pain score being lower in the LLLT compared to control and placebo groups. These findings were all statistically significant (p < 0.05). LLLT can alleviate the intensity of pain after the placement of orthodontic bands.

[Oral health in patients with systemic sclerosis]

The aim of this study was to conduct literature review about oral manifestations of scleroderma. Systemic sclerosis is a multisystem autoimmune disorder characterized by widespread fibrosis, vascular alterations and inflammation. Systemic sclerosis mainly affects people in age from 30 to 50 years, but the onset of disease can occur in any age. The disturbance of microcirculation with the activation and proliferation of endothelium and smooth muscle cells plays an important role in pathogenesis of sclerodrma. These changes lead to sclerosis and fibrosis of various part in human body. Orofacial manifestations of scleroderma include: reduced mouth opening, widening of periodontal ligament, teleangiectasia, bone lesions. Systemic scleroderma is often accompanied by Sjogren's syndrome. Oral manifestations of Sjogren's syndrome are recurrent parotitis, angular cheilitis, xerostomia and multiple caries. Sjogren's syndrome leads to negative impact on patients health and mental status. Orofacial manifestations of systemic sclerosis are still poorly known, that is why more researches should be made to improve dental treatment of patients with systemic sclerosis.

Th17 Cells and the IL-23/IL-17 Axis in the Pathogenesis of Periodontitis and Immune-Mediated Inflammatory Diseases

Innate immunity represents the semi-specific first line of defense and provides the initial host response to tissue injury, trauma, and pathogens. Innate immunity activates the adaptive immunity, and both act highly regulated together to establish and maintain tissue homeostasis. Any dysregulation of this interaction can result in chronic inflammation and autoimmunity and is thought to be a major underlying cause in the initiation and progression of highly prevalent immune-mediated inflammatory diseases (IMIDs) such as psoriasis, rheumatoid arthritis, inflammatory bowel diseases among others, and periodontitis. Th1 and Th2 cells of the adaptive immune system are the major players in the pathogenesis of IMIDs. In addition, Th17 cells, their key cytokine IL-17, and IL-23 seem to play pivotal roles. This review aims to provide an overview of the current knowledge about the differentiation of Th17 cells and the role of the IL-17/IL-23 axis in the pathogenesis of IMIDs. Moreover, it aims to review the association of these IMIDs with periodontitis and briefly discusses the therapeutic potential of agents that modulate the IL-17/IL-23 axis.

Main Oral Manifestations in Immune-Mediated and Inflammatory Rheumatic Diseases

Oral manifestations are frequent in patients with rheumatic diseases. The aim of this review is to offer readers practical advice concerning the onset, diagnosis and treatment of the main oral manifestations encountered in rheumatological and dental clinics. Signs and symptoms such as oral hyposalivation, xerostomia, temporomandibular joint disorders, periodontal disease, and dysphagia may be the first expression of a number of rheumatic diseases. Some of these manifestations are aspecific and very frequent, such as oral aphthosis, which can be the first manifestation in patients with systemic lupus erythematosus; some are potentially dangerous, such as jaw claudication during the course of giant cell arteritis; and some are very rare but peculiar, such as strawberry-like gingivitis in patients with granulomatosis with polyangiitis. Other oral manifestations are due to adverse reactions to disease-modifying anti-rheumatic drugs. Oral alterations in rheumatic diseases are frequently overlooked in clinical practice, but their prompt recognition not only allows the local lesions to be appropriately treated, but also makes it possible to identify an underlying systemic disease.

Assessment of the Dental Age of Children in the Polish Population with Comparison of the Demirjian and the Willems Methods

Background

Dental age is less affected than the bone age by nutritional and hormonal factors. The assessment of dental age in children is of value in clinical and forensic practice. The aims of this study were to compare the Demirjian method and the Willems method in the assessment of dental age in children in Poland and to consider the need to standardize dental age assessment.

Material/Methods

Polish children of Caucasian ethnicity (n=1,002) who were treated at a single orthodontic center between 1994–2016 included girls (n-540) and boys (n=462) aged between 4–17 years, and 1,002 panoramic radiographs were reviewed. Dental age was assessed using the Demirjian method and the Willems method, the findings of the two methods were compared with the chronological age of the study participants.

Results

Following statistical analysis, both the Demirjian method and the Willems method overestimated the dental age of the younger study participants, and underestimated the dental age of the older study participants. Both the Demirjian method and the Willems method had similar accuracy in estimating the chronological and dental age in the Polish population.

Conclusions

In the assessment of dental age in Polish children from panoramic radiographs, both the Demirjian method and the Willems method were accurate and should still be used as a method of choice. However, it seems reasonable to create international standards for the assessment of dentition maturity for this population to obtain a more acceptable range of error values between the dental age and chronological age.

The sensitive detection of ODAM by using sandwich-type biosensors with a cognate pair of aptamers for the early diagnosis of periodontal disease

This research aims to develop biosensors which could diagnose periodontal diseases in early phases and predict the illness stage of patients, in order to give them adequate treatment timely. Human odontogenic ameloblast-associated protein (ODAM) is considered to be a potential biomarker for periodontal diseases, based on high correlation between the level of ODAM in gingival crevicular fluid (GCF) and the degree of periodontitis. Many aptamers, including a cognate pair of aptamers which can bind to the different sites of ODAM, were successfully screened in a very stringent condition employing saliva as a counter target through the graphene oxide-based systemic evolution of ligands by exponential enrichment (GO-SELEX). For the characterization of the aptamer candidates, GO-based fluorescence resonance energy transfer (GO-FRET) and surface plasmon resonance (SPR) assays were conducted. The sandwich-type binding of a cognate pair of aptamers to ODAM was additionally confirmed by employing circular dichroism (CD) and magnetic beads-based fluorescence imaging methods. The resulting cognate pair of aptamers, OD64 and OD35, were found to have their dissociation constant (Kd), 47.71 nM and 51.36 nM, respectively. The minimum detectable concentrations of a sandwich-type SPR biosensor were found to be 0.24 nM and 1.63 nM, respectively, for both buffered and saliva samples. Finally, using this cognate pair of aptamers, a sandwich-type lateral flow strip biosensor was successfully realized. This research shows the potential for implementation of a cognate pair of aptamers on point-of-care biosensors which enables simple, rapid, and non-invasive saliva-based diagnosis of periodontal-related diseases that can overcome current diagnostic methods and improve health care system.

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

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.

Malnutrition and sarcopenia in a large cohort of patients with systemic sclerosis

Systemic sclerosis (SSc) is an autoimmune disease which may lead to malnutrition. Previous studies have defined it with different criteria. No thorough evaluations of sarcopenia in SSc are available. The aim of the present study was to assess the prevalence and the potential association of malnutrition and sarcopenia in a large cohort of SSc cases. A total of 141 SSc consecutive outpatients were enrolled. Body composition was analyzed by densitometry. Malnutrition was defined according to recently published ESPEN criteria, whereas sarcopenia was diagnosed in patients with reduced skeletal muscle index. Malnutrition was diagnosed in 9.2% of patients (95% CI, 4.4-14.0%). Malnourished patients had worse gastrointestinal symptoms according to UCLA SCTC GIT 2.0 questionnaire (p = 0.007), lower physical activity (p = 0.028), longer disease duration (p = 0.019), worse predicted DLCO/VA and FVC (p = 0.009, respectively), worse disease severity according to Medsger severity score (p < 0.001), lower hemoglobin (p = 0.023), and fat-free mass (p < 0.001) and were more often sarcopenic (p < 0.001). In multivariate analysis, only FVC (p = 0.006) and disease severity (p = 0.003), in particular for the lungs (p = 0.013), were confirmed to be worse in malnourished patients. Sarcopenia was diagnosed in 29\140 patients (20.7%; 95% CI, 14.0-27.4%); 11\29 were also malnourished. In multivariate analysis, sarcopenic patients had longer disease duration (p = 0.049), worse DLCO/VA (p = 0.002), and lung (p = 0.006) and skin (p = 0.014) involvement. In SSc, malnutrition defined with ESPEN criteria was found to be lower than previously reported. Sarcopenia was found to be somewhat common. Lung involvement was significantly associated with nutritional status and may not be explained only by muscle weakness.
