RESUMEN
Objective: To compare the levels of non-specific physical symptoms and pressure pain threshold (PPT) found in patients with masticatory myofascial pain with those found in patients with temporomandibular arthralgia alone. Methods: The study followed an observational and cross-sectional protocol. A total of 64 female patients were evaluated for the presence of painful TMD, non-specific physical symptom levels, and PPT. Results: The group of patients with masticatory myofascial pain presented a lower mean for PPT as well as a higher mean for standardized T-Scores for non-specific physical symptom levels. Conclusion: Statistically significant differences were found in non-specific physical symptom levels and PPT between patients with an exclusive diagnosis of masticatory myofascial pain and patients with a diagnosis, also exclusive, of temporomandibular arthralgia.
