The spectrum of orofacial manifestations in systemic sclerosis: a challenging management

Oral health and dental care challenges in scleroderma-perspectives of dentists, rheumatologists and patients

Objectives

The oral healthcare challenges of people living with scleroderma are poorly understood, yet frequently reported. This mixed methods study aimed to investigate oral health and dental care challenges associated with scleroderma from the perspective of dentists, rheumatologists and patients.

Methods

Dentists, rheumatologists and scleroderma patients in the UK completed a survey about their experiences of oral health, dental care and quality of life. People with scleroderma were also interviewed. We conducted descriptive analysis of quantitative data and used thematic analysis to examine qualitative data.

Results

A total of 95.5% of patients reported oral and dental manifestations of scleroderma (ODMS); 57.1% reported high physical impacts, 53.8% high psychological impacts and 47.7% high social impacts. Only 13% of patients were informed of ODMS at diagnosis. No dentist or rheumatologist felt fully confident in managing ODMS. The most frequent suggestion for improvement among patients and dentists was increased information for dentists. We identified three key themes: significant negative impact on quality of life, barriers to accessing dental care and characteristics of good dental care.

Conclusion

ODMS are prevalent issues, constituting a significant burden on quality of life. Rheumatologists should inform scleroderma patients of ODMS and embed oral health inquiries into annual reviews. Communication between medical and dental practitioners should be encouraged to facilitate early identification and management of ODMS.

Reciprocal effects of scleroderma and temporomandibular dysfunction between patient cohorts

OBJECTIVE

To estimate the prevalence of temporomandibular dysfunction in scleroderma patients according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and to correlate it with disease variables.

METHODS

Temporomandibular dysfunction was evaluated in 75 scleroderma patients and 74 healthy controls using DC/TMD. Gastrointestinal symptoms were evaluated through the University of California Los Angeles (UCLA) score in scleroderma patients.

RESULTS

There was no difference of prevalence in temporomandibular dysfunction [30 (40%) vs 30 (40.5%); p > 00.05] between scleroderma patients and healthy controls. Scleroderma patients had a significant reduction in all oral movements compared to healthy controls. Scleroderma patients with temporomandibular dysfunction had a statistically higher score in the UCLA distention/bloating item [1.75 (0.5-2.38) vs 0.75 (0.25-1.75); p < 0.05] than scleroderma patients without temporomandibular dysfunction.

DISCUSSION

Temporomandibular dysfunction prevalence between scleroderma patients and healthy controls is similar. In scleroderma patients, temporomandibular dysfunction reduces oral mobility and opening, which worsens distension/bloating.

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.

Clinician and patient experiences of managing and living with oral and dental manifestations of scleroderma: A scoping review

Oral and dental manifestations of scleroderma are extremely common, yet they are often overlooked within rheumatology and poorly understood within dentistry. Previous research has indicated the need to understand the oral and dental experiences of people living with scleroderma and those involved in their care. This scoping review aims, for the first time, to comprehensively map what is known regarding the identification and management of oral and dental manifestations of scleroderma, how these are experienced by people living with scleroderma, and to explore key characteristics of barriers and enablers to good oral and dental care in scleroderma. A scoping review was conducted using six databases (Embase, PubMed, PsychINFO, ASSIA, Scopus and SSCI), according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses - extension for Scoping Review. Grey literature was also included. Studies were eligible for inclusion if the full text and abstract were available in English, published between 2002 and 2022, and focused on the concept of oral and dental care in adults with scleroderma, either relating to identification and management, enablers and barriers to best practice, or patient experiences and well-being. Qualitative research which seeks to understand patients' lived experiences was a notable gap in the literature. Similarly, there was a significant lack of focus on the oral and dental manifestations of scleroderma in rheumatology. Three key features were identified which would facilitate best practice in research and clinical contexts: the necessity of multidisciplinary care; the necessity of centralising patient experience; and the necessity of mitigating barriers to dental care. We conclude that increased awareness of scleroderma within dentistry and streamlining referral procedures between the disciplines of dentistry and rheumatology, to enable the early identification and management of scleroderma, are crucial.

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.

Oral health education for systemic sclerosis patients: A booklet report

Purpose/objectives

Systemic sclerosis (SSc) is a rare chronic autoimmune disease characterized by vascular abnormalities and connective tissue disorders. In 2021, the multidisciplinary team of the university hospital recognized a demand for oral health information among SSc patients. This study aims to describe the development of an SSc oral health booklet and its validation by people with SSc.

Methods

For the development of the booklet, the project creators employed the action research methodology involving ten stages. SSc patients evaluated the material by filling out a digital form.

Results

One hundred and thirty-one people with SSc evaluated the booklet. It received an average score of 9.73 (SD: 0.80) in relevance, 9.82 (SD: 0.47) in explicitness, and 9.49 (SD: 0.93) in aesthetics. The final version was emailed to the participants and posted on social media.

Innovation

This is the first booklet that deeply addresses these issues in Portuguese and constitutes a soft technology to instruct and assist patients with SSc.

Conclusion

The production of high-quality educational materials on oral health for patients with SSc is necessary. The online distribution increased its reach and had great importance in the context of the COVID-19 pandemic.

Influence of systemic sclerosis on periodontal health: A case-control study

AIM

Patients with systemic sclerosis (SSc) present various clinical and radiological oral manifestations. However, precise evaluation of the oral features associated with diffuse cutaneous SSc (dcSSc) and limited cutaneous SSc (lcSSc) is limited. The objective of this study was to evaluate the periodontal ligament (PDL) surface in SSc patients in comparison with controls. Assessment of oral-health-related quality of life (OHRQoL) and the levels of different biomarkers in the gingival crevicular fluid (GCF) was performed.

MATERIALS AND METHODS

SSc patients and matched controls underwent standardized oral examination and cone-beam computed tomography (CBCT). Levels of interleukin-6 (IL-6), chemokine (C-X-C motif) ligand 4 (CXCL-4) and matrix metalloproteinase-9 (MMP-9) in the GCF were determined by enzyme-linked immunosorbent assay. PDL surface was measured on CBCT axial views. OHRQoL was quantified using the Mouth Handicap in SSc Scale (MHISS).

RESULTS

Thirty-nine SSc patients and 39 controls were included. SSc patients exhibited increased PDL surface, higher number of missing teeth as well as elevated IL-6, MMP-9 and CXCL-4 levels. Reduced mouth opening was observed in dcSSc but not in lcSSc patients. MHISS score was higher in dcSSc than in lcSSc patients. Although worse periodontal parameters were found in both subgroups compared with controls, dcSSc patients presented lower gingival inflammation.

CONCLUSIONS

SSc is associated with PDL space widening, impaired oral health and OHRQoL.

Systemic sclerosis gastrointestinal dysmotility: risk factors, pathophysiology, diagnosis and management

Nearly all patients with systemic sclerosis (SSc) are negatively affected by dysfunction in the gastrointestinal tract, and the severity of gastrointestinal disease in SSc correlates with high mortality. The clinical complications of this dysfunction are heterogeneous and include gastro-oesophageal reflux disease, gastroparesis, small intestinal bacterial overgrowth, intestinal pseudo-obstruction, malabsorption and the requirement for total parenteral nutrition. The abnormal gastrointestinal physiology that promotes the clinical manifestations of SSc gastrointestinal disease throughout the gastrointestinal tract are diverse and present a range of therapeutic targets. Furthermore, the armamentarium of medications and non-pharmacological interventions that can benefit affected patients has substantially expanded in the past 10 years, and research is increasingly focused in this area. Here, we review the details of the gastrointestinal complications in SSc, tie physiological abnormalities to clinical manifestations, detail the roles of standard and novel therapies and lay a foundation for future investigative work.

Gastrointestinal Tract Considerations Part I

The upper gastrointestinal (GI) tract is frequently involved in systemic sclerosis (SSc) and may impact quality of life, physical function and survival. Although we are currently very proactive in terms of screening for heart and lung involvement, patients with SSc are not routinely screened for GI involvement. This review details the available investigations for common upper GI symptoms in SSc, including dysphagia, reflux and bloating and provides advice as to how to integrate these investigations into current clinical care.

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.

Systemic Diseases with Oral Manifestations and Their Impact on Health-Related Quality of Life

Health-related quality of life is a multidimensional concept established to evaluate the physical, psychological, and social impacts of health conditions on individuals’ well-being. Various tools for measuring health-related quality of life can be categorized into two subsets: generic and disease–specific instruments. The oral cavity can be stricken by a broad range of local and systemic diseases and their systemic treatment modalities. The most common systemic illnesses associated with oral lesions are hematologic disorders, endocrinopathies, neurological disorders, gastrointestinal conditions, mucocutaneous and rheumatic diseases, and neoplastic processes. Their manifestations in the oral cavity are, in most cases, rather nonspecific but should not be overlooked. Oral health is one of the most important parts of overall health, thus it has been proposed that poor oral health may affect health–related quality of life. The presence of oral manifestations of systemic diseases has a negative impact on the daily functioning of patients, decreasing their overall well-being. This article will review the most common systemic diseases with oral manifestations and their impact on the health–related quality of life. Oral health researchers should put a stronger emphasis on the patient-reported quality of life as a primary outcome in future clinical trials. The significance of this area has still not been widely understood in the current dental literature even though it could help improve patients’ health-related quality of life.

Systemic sclerosis in adults. Part I: Clinical features and pathogenesis

Systemic sclerosis (SSc), also referred to as systemic scleroderma or scleroderma, is a rare, complex immune-mediated connective tissue disease characterized by progressive skin fibrosis and other clinically heterogenous features. The etiopathogenesis of SSc involves vasculopathy and immune system dysregulation occurring on a permissive genetic and epigenetic background, ultimately leading to fibrosis. Recent developments in our understanding of disease-specific autoantibodies and bioinformatic analyses has led to a reconsideration of the purely clinical classification of diffuse and limited cutaneous SSc subgroups. Autoantibody profiles are predictive of skin and internal organ involvement and disease course. Early diagnosis of SSc, with commencement of disease-modifying treatment, has the potential to improve patient outcomes. In SSc, many of the clinical manifestations that present early signs of disease progression and activity are cutaneous, meaning dermatologists can and should play a key role in the diagnosis and management of this significant condition. The first article in this continuing medical education series discusses the epidemiology, clinical characteristics, and pathogenesis of SSc in adults, with an emphasis on skin manifestations, the important role of dermatologists in recognizing these, and their correlation with systemic features and disease course.

Paul Klee's gastrointestinal maladies: A series of historical and clinical vignettes, part IV

Paul Klee (1879-1940), the 20th century Swiss-German artist, suffered and died from complications of systemic sclerosis (SSc, scleroderma). In a series of clinical and historical vignettes the various symptoms and complications of Klee's scleroderma are described. Here, I present evidence of Klee's multiple gastrointestinal (GI) symptoms and the significant impact they had on the quality of his life.

Dysphagia, reflux and related sequelae due to altered physiology in scleroderma

Systemic sclerosis is a connective tissue disease that presents with significant gastrointestinal involvement, commonly in the esophagus. Dysphagia is a common clinical manifestation of systemic sclerosis and is strongly related to esophageal dysmotility. However, there are multiple other contributing factors in each step in the physiology of swallowing that may contribute to development of severe dysphagia. The oral phase of swallowing may be disrupted by poor mastication due to microstomia and poor dentition, as well as by xerostomia. In the pharyngeal phase of swallowing, pharyngeal muscle weakness due to concurrent myositis or cricopharyngeal muscle tightening due to acid reflux can cause disturbance. The esophageal phase of swallowing is most commonly disturbed by decreased peristalsis and esophageal dysmotility. However, it can also be affected by obstruction from chronic reflux changes, pill-induced esophagitis, or Candida esophagitis. Other contributing factors to dysphagia include difficulties in food preparation and gastroparesis. Understanding the anatomy and physiology of swallowing and evaluating systemic sclerosis patients presenting with dysphagia for disturbances in each step can allow for development of better treatment plans to improve dysphagia and overall quality of life.

Gastrointestinal manifestations of systemic sclerosis: An updated review

Systemic sclerosis is an autoimmune disease characterized by vascular disease, fibrosis of the skin, and internal organ dysfunction. Gastrointestinal involvement is the most frequent complication of internal organs, impacting up to 90% of patients. Gastrointestinal involvement can affect any region of the gastrointestinal tract from the mouth to the anus, with a predominance of disorders being observed at the level of the upper digestive tract. The gastrointestinal involvement primarily involves the esophagus, small bowel, and rectum. The severity of gastrointestinal involvement affects quality of life and is a marker of worse prognosis and mortality in these patients. In this review, we describe the current findings regarding gastrointestinal involvement by this entity.

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.

Upper dysphagia in patients affected by systemic sclerosis: prevalence and features

Herein, we describe the prevalence and features of dysphagia in patients affected by systemic sclerosis (SS). We analysed the data of 19 patients obtained by administering the M.D. Anderson Dysphagia Inventory (MDADI) scale that measures dysphagia symptoms and by physical assessment consisting of judging specific lip, mandible and tongue performances (scale 0-3) and diadochokinesis, respiratory and phonatory functions (scale “poor”, “fair”, “good”, “normal”) according to Robertson’s method. Subjects also underwent flexible endoscopic examination of swallowing. MDADI showed that 74% of answers were included in “mild” class of disability, 21% as “moderate” and 5% as “severe”. The performance of lips, mandible and tongue that most frequently scored 1 were the opening (52.6% for the lips and 47.4% for the mandible) and the pop of the tongue (52.7%). The percentage of compromised respiratory, phonatory and diadochokinesis tests (“poor” or “fair”) was 81%, 70.1% and 74%, respectively. Flexible endoscopic examination of swallowing revealed pharyngolaryngeal sensory deficit and signs of oropharyngeal dysphagia in more than half of cases (58% and 53%, respectively). This study highlights the presence of dysphagia in SS patients and demonstrates the importance of a multidimensional approach that includes subjective and objective evaluation to characterise specific features of swallowing alterations that have a high-impact on upper dysphagia.

Prevalence of Oral and Maxillofacial Disorders in Patients with Systemic Scleroderma-A Systematic Review

BACKGROUND

Systematic scleroderma is a rare chronic autoimmune disease of unknown aetiology. The aim of this study was to identify the prevalence of orofacial pathognomonic conditions in patients with systemic scleroderma using only randomised prospective studies that investigated the treatment of oral and maxillofacial changes, highlighted associations between the disease and Sjogren's syndrome, and/or analysed the effect of oral hygiene.

METHODS

The literature was systematically reviewed based on Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science articles published up to March 2020. The primary endpoint of this analysis was defined as an estimation of the prevalence of oral mucosal changes in different areas of the oral cavity (oral mucosa, tongue, lip, periodontal status, bones, and other regions) in patients suffering from scleroderma. Therefore, a systematic literature search (Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science) was conducted and limited by the publication date (1950-03/2020) and the publication language (English). Extracted frequencies were pooled using methods for meta-analysis. In order to obtain the highest level of evidence, only prospective study reports were considered to be eligible.

RESULTS

After full-text screening, 14 (766 patients) out of 193 publications were eligible for the final analysis. Twelve studies produced reliable results in the final data sets. Calculation of the pooled effect estimate (random effects model) revealed a prevalence of 57.6% (95% CI: 40.8-72.9%) for the main area "lip". For the area "oral mucosa", a prevalence of 35.5% (95% CI: 15.7-62.0%) was calculated. The prevalence for "other regions" was only based on studies with salivary changes and was calculated to be 25.4% (95% CI: 14.2-41.3%).

CONCLUSION

The most pathognomonic conditions in the orofacial region in patients with systemic scleroderma affect the lips, oral mucosa, and salivary glands.

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.

Measuring the impact of systemic sclerosis on oral health-related quality of life in a UK population

BACKGROUND

The objective of the present study was to identify the impact of systemic sclerosis (SSc) upon oral health-related quality of life (OHRQoL) of affected individuals resident in the UK.

METHODS

A total of 100 patients and their partners or carers were invited to complete questionnaires regarding the impact of SSc on quality of life and psychological well-being using valid and reliable patient-reported outcome measures (OHIP-14, MHISS, OIDP, MDAS and HADS). A total of 50 patients with SSc and 18 partners or carers who acted as controls returned the completed questionnaires. Statistical analyses were performed for comparisons of different variables.

RESULTS

All the mean scores of OHIP-14 (SSc [16.5 ± 12.4] Vs controls [6.06 ± 7.6, p = 0.001]) and MHISS components were significantly higher in patients than those of control group (SSc [21.26 ± 12] Vs controls [4.8 ± 7.3, p < 0.0001]). Majority of OIDP mean scores were significantly worse in patients compared with controls [SSc (10 ± 8.7) Vs controls (1.72 ± 3.4, p < 0.0001)]. The mean of total MDAS [SSc (11.7 ± 5.3) Vs controls (9.5 ± 4.4)] and HADS scores were higher in patients compared to controls (SSc depression [4.8 ± 3.3] and anxiety [6 ± 4.6] Vs controls [3.7 ± 3.1] [4.7 ± 3.9]).

CONCLUSIONS

Although the present study is limited by the low response rate and its cross-sectional design, present results highlighted that systemic sclerosis has a negative impact on OHRQoL of the affected individuals; hence, the evaluation of associated psychological impact including anxiety and depression symptoms is needed to better understand, monitor and evaluate the disease comorbidity in patients with SSc.

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.

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.

Dental management of scleroderma patients using pentoxifylline plus vitamin E with and without TheraBite® to reduce trismus: Two case reports and brief review of literature

To provide evidence supporting the off label use of pentoxifylline and vitamin E especially by dentists with TheraByte to reduce trismus in scleroderma patients.

Multiple External Root Resorption of Teeth as a New Manifestation of Systemic Sclerosis-A Cross-Sectional Study in Japan

BACKGROUND

Multiple external root resorption (MERR) has been reported in systemic sclerosis (SSc) patients in Japan and Spain. To establish whether MERR is a new manifestation, we investigated the prevalence of MERR and systemic and oral manifestations to be associated with MERR in patients with SSc.

METHODS

Root resorption was detected by dental X-rays, panoramagraphy or cone beam computed tomography (CBCT). The prevalence of systemic and oral manifestations was examined by rheumatologists and dentists, respectively. Autoantibodies were investigated using laboratory tests.

RESULTS

MERR was detected in four out of the 41 patients (9.8%) who participated in the present study. The prevalence of digital ulcers was significantly higher in patients with MERR (MERR vs non-MERR, 75% vs 16.2%, p < 0.05), whereas that of other systemic manifestations was not. The prevalence of face skin sclerosis (100% vs 10.8%, p < 0.01), calcinosis at the facial region (75% vs 0%, p < 0.01), limited mouth opening (75% vs 18.9% p < 0.05), temporomandibular disorder symptoms (50% vs 2.7%, p < 0.05), and tongue rigidity (75% vs 2.7%, p < 0.05) was significantly higher in patients with MERR.

CONCLUSION

SSc patients with MERR had highly homogenous maxillofacial manifestations. Further clinical and basic studies are needed to elucidate the mechanisms underlying MERR in SSc patients.

Volumetric Cone Beam Computed Tomography for the Assessment of Oral Manifestations in Systemic Sclerosis: Data from an EUSTAR Cohort

Background: Oral health issues are commonly reported in systemic sclerosis (SSc), comprising a broad spectrum of manifestations, e.g., reduced mouth opening, periodontal disease, increased periodontal ligament (PDL) space width, and mandibular resorption. We aimed to assess oral radiographic abnormalities, particularly PDL space widening and erosions, and to identify potential relations with disease measures. Methods: cross-sectional study in 43 SSc and matching controls receiving systematic oral assessments (full mouth dental/periodontal) and imaging (radiographs and cone beam computed tomography (CBCT)). Associations between disease variables and radiologic findings were investigated by univariate and multivariate analysis (SPSS-v.20, p < 0.05). Results: CBCT demonstrated generalized PDL space widening in up to half SSc, with at least one tooth involved, essentially in the posterior region (p < 0.05). Significant correlations between number of teeth with PDL space widening and disease severity, skin score, disease subset, topoisomerase I specificity, age, and disease duration were reported (p < 0.05). Additionally, mandibular erosions were described in one out of four patients, commonly condylar erosions. Conclusions: Tridimensional CBCT approach confirmed widening of PDL and mandibular erosions as common dental findings in scleroderma. Furthermore, widened PDL spaces correlated with several disease characteristics including severity, skin extent, and antibody profile.

[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.

Mandibular resorption and vocal cord paralysis: a catastrophic form of systemic sclerosis

Sudden respiratory distress in association with severe weight loss are unusual features of systemic sclerosis (SSc). We report the case of a 56-year-old Caucasian woman with a 9-year history of a diffuse form of SSc who presented with acute stridor due to vocal cord paralysis and required an emergency tracheostomy. She had sought medical attention only after 4 years of disease onset, presenting with a mask-like face, diffuse skin thickening, acro-osteolysis and severe interstitial lung disease. Even though skin tightness improved after immunosuppressive treatment, several spontaneous facial fractures and episodes of dysphagia and choking occurred in the years that followed. At the time of stridor, she was severely malnourished and a percutaneous endoscopic gastrostomy was required for feeding. Permanent vocal cord damage in combination with severe loco-regional bone resorption resulted in severe disability and impaired nutrition. We hereby highlight the features of SSc for which therapy remains challenging.

Impact of systemic sclerosis oral manifestations on patients' health-related quality of life: A systematic review

BACKGROUND

Oropharyngeal features are frequent and often understated in the treatment clinical guidelines of systemic sclerosis in spite of important consequences on comfort, aesthetics, nutrition and daily life. The aim of this systematic review was to assess a correlation between the oropharyngeal manifestations of systemic sclerosis and patients' health-related quality of life.

METHODS

A systematic search was conducted using four databases [PubMed® , Cochrane Database® , Dentistry & Oral Sciences Source® and SCOPUS® ] up to January 2018, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Grey literature and hand search were also included. Study selection, risk bias assessment (Newcastle-Ottawa scale) and data extraction were performed by two independent reviewers. The review protocol was registered on PROSPERO database with the code CRD42018085994.

RESULTS

From 375 screened studies, 6 cross-sectional studies were included in the systematic review. The total number of patients included per study ranged from 84 to 178. These studies reported a statistically significant association between oropharyngeal manifestations of systemic sclerosis (mainly assessed by maximal mouth opening and the Mouth Handicap in Systemic Sclerosis Scale) and an impaired quality of life (measured by different scales). Studies were unequal concerning risk of bias mostly because of low level of evidence, different recruiting sources of samples and different scales to assess the quality of life.

CONCLUSION

This systematic review demonstrates a correlation between oropharyngeal manifestations of systemic sclerosis and impaired quality of life, despite the low level of evidence of included studies. Large-scaled studies are needed to provide stronger evidence of this association.

Gastrointestinal and Hepatic Disease in Systemic Sclerosis

Although classification criteria for systemic sclerosis (SSc) do not incorporate gastrointestinal tract (GIT) manifestations often present in this disease, the GIT is the most common internal organ involved. Pathophysiology of GIT involvement is thought to be similar to other organs in SSc with fibroproliferative vascular lesions of small arteries and arterioles, increased production of profibrotic growth factors, and alterations of innate, humoral, and cellular immunity. These processes result in neuropathy progressing to myopathy with eventual fibrosis. Proper diagnostics and therapeutics for SSc-GIT involvement require the treating physician to have an understanding of an integrated approach and potential medication adverse effects.

Gastrointestinal Manifestations of Systemic Sclerosis

Systemic sclerosis (SSc) is a rare autoimmune disease characterized by fibroproliferative alterations of the microvasculature leading to fibrosis and loss of function of the skin and internal organs. Gastrointestinal manifestations of SSc are the most commonly encountered complications of the disease affecting nearly 90% of the SSc population. Among these complications, the esophagus and the anorectum are the most commonly affected. However, this devastating disorder does not spare any part of the gastrointestinal tract (GIT), and includes the oral cavity, esophagus, stomach, small and large bowels as well as the liver and pancreas. In this review, we present the current understanding of the pathophysiologic mechanisms of SSc including vasculopathy, endothelial to mesenchymal transformation as well as the autoimmune pathogenetic pathways. We also discuss the clinical presentation and diagnosis of each part of the GIT affected by SSc. Finally, we highlight the latest developments in the management of this disease, addressing the severe malnutrition that affects this vulnerable patient population and ways to assess and improve the nutritional status of the patients.

Orofacial consequences of systemic sclerosis: A systematic review

Orofacial involvement is common and often understated in the treatment clinical guidelines of systemic sclerosis. It impairs daily life by having repercussions on comfort, nutrition, aesthetics and self-confidence. This review aimed at describing exhaustively the different orofacial consequences of systemic sclerosis. A systematic search was conducted using four databases (PubMed, Cochrane Library, Dentistry & Oral Sciences Source and SCOPUS) up to December 2016 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Grey literature and hand search were also included. To be eligible for the inclusion, studies needed to meet the following criteria: randomised controlled trials, cross-sectional studies, case-control studies, pilot studies or cohort studies and full text available in English or French, with abstract. The studies had to concern at least 30 patients suffering from systemic sclerosis and having clinical and radiological oropharyngeal examination. The diagnosis of systemic sclerosis had to be determined according to precise recommendations; the retrieved oropharyngeal manifestations had to affect hard or soft tissues of the mouth and/or pharynx and needed to be evaluated with clinical measures. Study selection, risk bias assessment (Newcastle-Ottawa scale) and data extraction were performed by two independent reviewers. The retrieved features were microstomia and xerostomia associated with real hyposialia, temporomandibular joint symptoms, high caries experience, periodontal diseases as well as an increased risk of oral cavity and pharynx cancer. Early diagnosis enabling early management, prevention and oral hygiene is the key to avoid complicated and invasive procedures. Studies with higher level of evidence remain necessary to create standardised protocols.
