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.
