Randomized Controlled Trial Comparative Study Observational Study
Orofacial Manifestations and Temporomandibular Disorders of Systemic Scleroderma: An Observational Study.
Scleroderma is a disorder involving oral and facial tissues, with skin hardening, thin lips, deep wrinkles, xerostomia, tongue rigidity, and microstomia. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in Systemic Sclerosis (SSc) patients compared with healthy people. Eighty patients (6 men, 74 women) fulfilling ACR/EULAR SSc Criteria were enrolled. ⋯ SSc patients complained more frequently (78.8%) of oral symptoms (Xerostomia, dysgeusia, dysphagia and stomatodynia) than controls (28.7%) (χ² = 40.23 p = 0.001). TMD symptoms (muscle pain on chewing, difficulty in mouth opening, headaches) were complained by 92.5% of SSc patients and by 76.2% of controls (χ² = 8.012 p = 0.005). At the clinical examination, 85% of SSc patients showed restricted opening versus 20.0% of controls (χ² = 67.77 p = 0.001), 81.2% of SSc showed reduced right lateral excursion versus 50% of controls (χ² = 17.316 p = 0.001); 73.8% of SSc showed limited left lateral excursion versus 53.8% of controls (χ² = 6.924 p = 0.009); and 73.8% of SSc had narrow protrusion versus 56.2% of controls (χ² = 5.385 p = 0.02).
