The objective was to investigate the prevalence of temporomandibular dysfunction-TMD-in severe and moderate hemophiliac A and B patients and healthy men as control group. Hemophilia complication is chronic arthropathy that results from repeated joint bleeding, leading to limited movement. Limitation of jaw movement is present in patients with TMD. Hemophiliac patients were recruited in the Hemophilia outpatient clinic at
SUMMARY:The jaw muscles are essential components in the stomatognatic system. Their complex architecture allows them to execute several motor tasks. One of the structural peculiarities is the presence of hybrid and neonatal fibers.We studied the differences of the fiber-type in masseter and temporalis muscles along the first to nineth decades in both genders. Seventy-four (74) samples were analyzed by immunohistochemistry. Slow and fast muscle fibers distribution was similar in both muscles in both genders. Hybrid fiber was observed in all decades, and its frequency decreased significantly (p<0.001) with aging in masseter. Neonatal myosin expression was observed in all decades, its expression was more frequent in masseter (p=0.01), and males in temporalis (p=0.025). Decrease of the cross sectional area of fast and slow fibers, and decrease of capillary density were detected with aging. These morpho-immunohistochemical alterations on masseter and temporalis muscles correlated to the decrease in bite force with aging.
BACKGROUND AND OBJECTIVES:To relate biopsychosocial variables of Research Diagnostic Criteria for Temporomandibular Disorders to groups of patients with temporomandibular disorders, temporomandibular disorders and migraine and a control group. METHODS: This is a cross-sectional observational study where 280 consecutive patients were evaluated and distributed in three groups: group I (140 control individuals); group II (65 individuals with muscle temporomandibular disorders) and group III (75 individuals with migraine and muscle temporomandibular disorders). Exclusion criteria were individuals with clinical history of muscle inflammatory processes, muscle spasms, contractures and acute temporomandibular joint traumatic injury. RESULTS: Group III individuals had association with severe depression (p<0.001), level 4 in pain severity (p=0.004), unspecific physical symptoms without severe pain (p<0.0001) and unspecific symptoms with severe pain (p<0.00001). There has been significant difference between females and males in group III (Z=2.59; p=0.001), with longer pain duration among females. The percentage of females in group III was significantly higher as compared to males (p=0.004).
CONCLUSION:The relationship between variables and the three groups has shown a higher number of individuals with more severe symptoms in group III. So, it is understood that migraine is a morbid condition often associated to temporo- There is the need for multidisciplinary evaluation of these individuals to optimize treatment and minimize morbidity, costs and the number of medical visits.
