To determine in a representative sample of the Australian adult population the relationship between age, gender, and two components of perceived stress (distress and control) and to investigate whether the relationship of perceived stress and temporomandibular disorder (TMD)-related orofacial pain symptoms was modified by gender or age. ⋯ The higher prevalence of TMD-related orofacial pain symptoms in females was better explained by their lower perception of control than from a greater perception of distress.
-
To describe the cause, clinical signs, and symptoms of patients presenting to a tertiary care center with iatrogenic lesions to the mandibular branches of the trigeminal nerve. ⋯ Neuropathic pain, as well as anesthesia, frequently occurs following iatrogenic trigeminal nerve injury similar to other posttraumatic sensory nerve injuries. This must be acknowledged by clinicians as a relatively common problem and informed consent appropriately formulated for patients at risk of trigeminal nerve injuries in relation to dentistry requires revision.
-
To compare prevalences of self-reported comorbid headache, neck, back, and joint pains in respondents with temporomandibular joint and muscle disorder (TMJMD)-type pain in the 2000-2005 US National Health Interview Survey (NHIS), and to analyze these self-reported pains by gender and age for Non-Hispanic (NH) Whites (Caucasians), Hispanics, and NH Blacks (African Americans). ⋯ TMJMD-type pain was most often associated with other common pains, and seldom existed alone. Two or more comorbid pains were common. Gender, race, and age patterns for pains with TMJMD-type pain resembled the specific underlying comorbid pain.
-
To establish a quantitative sensory testing (QST) profile in the trigeminal (V) area and test for site and gender differences in healthy humans. ⋯ Application of this standardized QST protocol may allow for a better understanding of the underlying mechanisms from somatosensory phenotypes and provide basic information for the study of sensory dysfunctions in the V area.
-
To examine the effect of decreased estrogen level and altered diet hardness on condylar cartilage morphology of the rat temporomandibular joint (TMJ) and on the expression of condylar cartilage estrogen receptor alpha (ERa) and matrix metalloproteinase-8 (MMP-8). ⋯ The rat TMJ condylar cartilage is sensitive to changes in estrogen levels and altered diet hardness.
