Comparative Study
TMD in patients with primary Sjögren syndrome: a comparison with temporomandibular clinic cases and controls.
The aim of this study was to investigate the prevalence of temporomandibular disorders (TMD) in patients with primary Sjögren syndrome (1 degree SS), analyze the impact of the disease on mandibular function, and assess psychosocial distress. ⋯ Both 1 degree SS and chronic TMD may be associated with appreciable physical discomfort and psychosocial dysfunction. However, the underlying mechanisms of the oral dysfunction of 1 degree SS and TMD are quite different and essentially unrelated.

The purpose of this project was to test the within-day and between-days reproducibility of a new and inexpensive algometer. Twelve symptom-free men and nine women participated. Pressure pain thresholds (PPTs) of the bilateral masseter and temporalis muscles were assessed during four sessions (mornings and afternoons of days 1 and 3). ⋯ When the within-session reproducibility for all muscles was considered, only the PPT values between measurements 2 and 4 were not significantly different. Analysis of variance showed that the interindividual variability of PPT was 1.4 to 6.8 times higher than the variability observed within or between sessions and days. No gender difference was found.

Recently developed Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) have been shown to be reliable for diagnosing and assessing TMD in U. S. and Swedish adult populations; however, few studies have focused on clinical examination methods and diagnostic criteria for use with children and adolescents. ⋯ Interexaminer and intraexaminer reliability was assessed for clinical examination, questionnaire items, and diagnosis. Reliability values ranged from acceptable to excellent for the RDC/TMD clinical exam and questionnaire, and from good to excellent reliability for measuring virtually all modified clinical parameters of TMD assessed in these young patients.
