Periodontal space widening in patients with systemic sclerosis: a probable explanation

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: 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.

[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.

Orofacial manifestations of systemic sclerosis

Systemic sclerosis (SSc) is a multisystem disease of unknown aetiology characterised by microangiopathy, dysregulated immune function and tissue remodelling, which commonly involves the oral cavity. Orofacial manifestations of SSc contribute greatly to overall disease burden and yet are regularly overlooked and under-treated. This may reflect a pre-occupation amongst rheumatology clinicians on potentially life-threatening internal organ involvement, but is also a consequence of insufficient engagement between rheumatologists and dental professionals. A high proportion of SSc patients report difficulty accessing a dentist with knowledge of the disease and there is recognition amongst dentists that this could impact negatively on patient care. This review shall describe the clinical features and burden of orofacial manifestations of SSc and the management of such problems. The case is made for greater collaborative working between rheumatologists and dental professionals with an interest in SSc in both the research and clinical setting.

Review of common conditions associated with periodontal ligament widening

Purpose

The aim of this article is to review a group of lesions associated with periodontal ligament (PDL) widening.

Materials and Methods

An electronic search was performed using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as “periodontium”, “periodontal ligament”, “periodontal ligament space”, “widened periodontal ligament”, and “periodontal ligament widening”.

Results

Out of nearly 200 articles, about 60 were broadly relevant to the topic. Ultimately, 47 articles closely related to the topic of interest were reviewed. When the relevant data were compiled, the following 10 entities were identified: occlusal/orthodontic trauma, periodontal disease/periodontitis, pulpo-periapical lesions, osteosarcoma, chondrosarcoma, non-Hodgkin lymphoma, progressive systemic sclerosis, radiation-induced bone defect, bisphosphonate-related osteonecrosis, and osteomyelitis.

Conclusion

Although PDL widening may be encountered by many dentists during their routine daily procedures, the clinician should consider some serious related conditions as well.

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

Systemic sclerosis (SSc) is a rare multisystem connective tissue disorder characterized by the triad fibrosis, vasculopathy and immune dysregulation. This chronic disease has a significant impact on the orofacial region that is involved in more than two-thirds of the cases. SSc patients can show a wide array of oral manifestations, which are usually associated with a severe impairment of the quality of life. They often present a decreased the salivary flow and a reduced mouth opening that contribute substantially to the worsening of the oral health status. Therefore, SSc patients require specific and multidisciplinary interventions that should be initiated as early as possible. The identification of specific radiological and clinical signs at the early stage will improve the management of such patients. This study reviews the wide spectrum of orofacial manifestations associated with SSc and suggests clues for the oral management that remains challenging.

Periodontal status of adults with systemic sclerosis: case-control study

BACKGROUND

Systemic sclerosis (SSc) is a systemic autoimmune disease that affects connective tissue in the skin, blood vessels, and major organs of the body. This project aims to compare the periodontal status of dentate Hong Kong Chinese with and without SSc.

METHODS

Thirty-six non-smoking adults with SSc (one male and 35 females: aged 50.6 ± 11.7 years; free from Sjögren syndrome) attending a teaching hospital were age- and sex-matched to systemically healthy controls attending a dental hospital. Both groups had similar demographic characteristics but a lower proportion of patients with SSc were working or studying (P <0.05). Twenty-three (32%) of all participants were regular dental attendees. Orthopantomogram radiographs were taken. Participants were surveyed and periodontally examined.

RESULTS

Both groups had a similar number of erupted teeth, proportion of sites with detectable plaque, and mean full-mouth clinical attachment level, whereas controls had less bleeding on probing (49.3% ± 22.6% versus 78.4% ± 19.6%; P <0.001) and a shallower mean full-mouth probing depth (1.92 ± 0.44 mm versus 2.52 ± 0.58 mm; P <0.001). Radiographically, patients with SSc had wider periodontal ligament spaces (0.36 ± 0.06 mm versus 0.33 ± 0.03 mm; P <0.01).

CONCLUSIONS

Hong Kong Chinese adults with SSc seem to exhibit higher levels of periodontal inflammation and wider radiographic periodontal ligament spaces than age- and sex-matched controls. Future studies are warranted to further investigate any associations between these periodontal features and SSc.

Early diagnosis of progressive systemic sclerosis (scleroderma) from a panoramic view: report of three cases

Systemic sclerosis (scleroderma) is a multisystem disease involving the skin, lungs, heart, kidneys and gastrointestinal tract. It is probably owing to a disorder of the immune system. It may also have some oral manifestations, including limited ability to open the mouth, widening of the periodontal ligament (PDL) space and mandibular bone resorption. We report here on three asymptomatic cases that were referred to our oral and maxillofacial radiology centre for another reason, and in which we suspected scleroderma based on the widening of the PDL in the panoramic view. The early diagnosis was finally confirmed by pathological findings.

Oral health of Chinese people with systemic sclerosis

The aim was to study oral health status, salivary function, and oral features of Chinese people with Systemic Sclerosis (SSc). Chinese people with SSc attending a university specialist clinic were invited for a questionnaire survey and a clinical examination. Ethics approval was sought (UW 08-305). Gender- and age-matched individuals without SSc who attended a university dental hospital were recruited for comparison. Forty-two SSc patients with a mean age of 54.0 ± 12.2 were examined. This study found no Chinese people with systemic sclerosis were periodontally healthy and many (76%) had periodontal pockets despite most of them (93%) practiced daily tooth-brushing. They all had caries experience (DMFT = 10.5) and many (65%) had untreated decay. Mucosal telangiectasia was a common oral feature (80%). They had lower resting salivary flow rates (0.18 ± 0.17 ml/min vs. 0.31 ± 0.21 ml/min; p = 0.003) and pH values (6.90 ± 0.40 vs. 7.28 ± 0.31; p < 0.001) and reduced maximal mouth opening (40.1 ± 6.5 mm vs. 43.6 ± 7.0 mm) than people without SSc.

Periodontal Status of Adults With Systemic Sclerosis: Case-Control Study

Background: Systemic sclerosis (SSc) is a systemic autoimmune disease that affects connective tissue in the skin, blood vessels and major organs of the body. This project aimed to compare the periodontal status of dentate Hong Kong Chinese with and without SSc. Methods: Thirty-six non-smoking adults with SSc (35 women; 50.6 ? 11.7 years, free from Sjogren's syndrome) attending a teaching hospital were age- and sex-matched to systemically healthy controls attending a dental hospital. Both groups had similar demographic characteristics but a lower proportion of SSc patients were working or studying (p < 0.05). Twenty-three (32.0%) of all participants were regular dental attendees. Orthopantomogram rediograph were taken. Participants were surveyed and periodontally examined. Results: Both groups had a similar number of erupted teeth, proportion of sites with detectable plaque, and mean full-mouth probing attachment level, whereas controls had less bleeding on probing (BOP(%), 49.3 ? 22.6 vs. 78.4 ? 19.6; p < 0.001) and a shallower mean full-mouth probing pocket depth (PPD(mm), 1.92 ? 0.44 vs. 2.52 ? 0.58; p < 0.001). Radiographically, SSc patients had wider periodontal ligament spaces. (PDL (mm), 0.36 ? 0.06 vs. 0.33 ? 0.03, p < 0.01) Conclusion: Hong Kong Chinese SSc adults seem to exhibit higher levels of periodontal inflammation and wider radiographic PDL spaces than age- and sex- matched controls. Future studies are warranted to further investigate any associations between these periodontal features and SSc.
