Resumo
O Bruxismo do Sono (BS) é uma atividade oral caracterizada pelo ranger e/ou apertar dos dentes durante o sono, usualmente associado com microdespertares. Muitos estudos têm investigado a relação entre Bruxismo do Sono e Disfunção Temporomandibular (DTM), mas os resultados não são conclusivos e a inter-relação entre as duas entidades ainda não foi explicada. Além disso, os estudos também mostram forte associação entre Bruxismo do Sono e Cefaleias, mas ainda não há conclusão definitiva. O objetivo do presente estudo foi estimar o risco da ocorrência de DTM dolorosa e cefaleias primárias em pacientes com ou sem bruxismo do sono. A amostra foi composta por 301 indivíduos (253 mulheres e 48 homens), com a idade variando de 18 a 76 anos (Média de idade de 37,45 anos). O Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) foi usado para o diagnóstico e classificação da DTM. O Bruxismo do Sono foi diagnosticado de acordo com os critérios clínicos propostos pela American Academy of Sleep Medicine e a cefaleia foi diagnosticada por meio de um questionário baseado na Classificação Internacional de Cefaléias (CIC, 2004). A amostra foi dividida em 4 grupos: 1) Pacientes sem DTM dolorosa e sem BS (15,9%); 2) Pacientes sem DTM dolorosa e com BS (6,3%); 3) Pacientes com DTM dolorosa e sem BS (24,6%); 4) Pacientes com DTM dolorosa e com BS (53,2%). Os resultados mostraram que os pacientes com bruxismo do sono apresentam um risco aumentado para a ocorrência de DTM dolorosa quando comparado aos pacientes sem bruxismo do sono (OR=5,5 95% IC: 3,3-9,9, p<0,001), sendo esse risco significativo somente para dor miofascial (OR= 5,4 95% IC: 1,6-18,2, p=0,0047). Houve um risco aumentado para migrânea nos grupos 3 (p=0,0003, OR= 5,3, IC: 2,2-12,9) e 4 (p<0,0001, OR=11,7, IC: 5,0-27,3). Para cefaleia do tipo tensional houve risco aumentado somente para o grupo...
Sleep bruxism is an oral activity characterized by grinding or clenching of the teeth during sleep, usually associated with sleep arousals. Many studies have investigated the relationship between sleep bruxism and Temporomandibular Disorders (TMD), but the findings are not conclusive and their inter-relationship is still far from being explained. Furthermore, studies also show a strong association between BS and headaches, but were not yet established any definitive conclusions. The aim of this study was to estimate the risk of occurrence of painful temporomandibular disorders and primary headaches in patients with or with no sleep bruxism. The sample consisted of 301 individuals (253 women and 48 men), with ages varying from 18 to 76 years (average of 37.45 years). The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were used to diagnose TMD patients, SB was diagnosed by clinical criteria proposed in the literature and HA were diagnosed based on the International Classification of Headache Disorders. The sample was divided into four groups: 1) Patients without painful TMD and without SB (15,9%); 2) Patients without painful TMD and with SB (6,3%); 3) Patients with painful TMD and without SB (24,6%) and 4) Patients with painful TMD and SB (53,2%). The results showed that patients with sleep bruxism had an increased risk for the occurrence of painful temporomandibular disorders compared to patients with no sleep bruxism (OR=5.5, 95% CI: 3.0-9.9, p<0,001), this risk was significant only for miofascial pain (OR= 5.4, 95% CI: 1.6-18.2, p=0,0047). There was an increased risk for migraine in groups 3 (OR= 5.3, 95% CI: 2.2-12.9, p=0.0003) and 4 (OR=11.7, 95% CI: 5.0-27.3, p<0.0001). For tension type headache had an increased risk only for group 4 (OR=5.9, 95% CI: 2.2-15.8, p=0.0007). Unable to establish a cause and effect relationship between sleep bruxism, temporomandibular...
