Perturbação do sono e disfunção temporomandibular

: estudo clínico

Abstract

TMD (Temporomandibular Dysfunction) is assumed as a group of non-pathological signs and symptoms affecting a high percentage of the general population. The TMD can affect the temporomandibular joint, as well as the muscles of the stomatognathic system. The DTM has multifactorial etiology. Sleep is a complex behavior, essential to the human organism, and displays a complementary state with the wakefulness. Serious changes of this physiological state can lead to a high number of complaints / problems for individuals, just as depressive states, mood swings, chronic pain, psychological and psychosocial conditions and stress. A high percentage of the population that has sleep disorders, take on pharmacological treatment to quell the disturbance of the circadian cycle, although there are alternative treatments. The present work aims to study the relationship between the use of sleep medication and decreased temporomandibular pain intensity as well as the presentation of joint and muscle pain for the patient, depending on the subjective perception of sleep. For this study, 49 patients were randomly selected from the Dental Clinic of the University ‘Universidade Católica Portuguesa – Centro Regional das Beiras’. These patients underwent various surveys at the end of each dental appointment. The surveys are restricted to Index RDC / TMD ('Research Diagnostic Criteria for Temporomandibular Disorders') - axis I/ axis II and the Pittsburgh Sleep Quality Index (PSQI). The results showed that, given the small number of patients studied under influence of pharmaceutical components, it is necessary a study with larger order subgroups to achieve draw reliable conclusions. Thus, it is emphasized that this study allowed the comprehension that there are no statistically significant relationships between the proposed objectives.
