Abstract

The aims of this study was to investigate the clinical and radiographic features of temporomandibular dysfunction in the patients with RA to elucidate whether the RA patients would be a risk group for TMD. The 35 patients with temporomandibular joint dysfunction were included for this study, of which 15 had rheumatoid arthritis diagnosed by a rheumatologist, and other 20 was control group and they didn't have any history or clinical signs related to it. Clinical symptoms and signs of temporomandibular joint disorders, radiographic and MRI findings of temporomandibular joint were investigated. The results were compared between two groups. In RA group bilateral pain, morning stiffness, reduced opening range, and crepitations were more frequently reported than control group. Radiologic findings such as sclerosis and flattening of condylar head, marginal proliferation, and erosion of glenoid fossa were more frequently observed in RA group than control group. Disk destruction, cortical bone erosion, and intraarticular enhancement were more prominenet in RA group. From theses results, it can be concluded that many RA patients will develop TMD symptoms and the structural changes of TMJ is more extensive than the usual TMD cases.

이 논문의 목적은 류마티스성 관절염 환자에게서 나타나는 측두하악관절장애에 대하여 임상적 및 방사선학적 특징을 평가하는 것이다. 경북대학교병원 류마치스내과에서 류마치스성 관절염을 가지고 있는 것으로 판명된 환자 중에 측두하악관절 기능장애의 증상을 나타내는 환자 15명을 실험군으로 하고, 경북대학교병원 구강내과에서 측두하악관절장애로 진단된 환자 20명을 대조군으로 하였다. 류마티스성 관절염 환자에서 근막동통, 아침경직감, 측두하악관절 운동범위의 감소, 염발음의 발생빈도가 각각 86.7%, 73.3%, 80.0%, 73.3%이었으나, 대조군에서는 각각 55.0%, 15.0%, 40.0%, 30.0%로 나타나 류마티스성 관절염 환자에서 측두하악관절장애의 증상의 발생 빈도가 훨씬 높게 나타났다. 방사선학적 특징 중에 두 군 간에 발생빈도에 있어서 유의한 차이를 나타내는 소견은 과두의 평탄화와 경화, 변연골증식, 관절와의 침식 등이었으며 모두 류마티스성 관절염 환자에게서 많이 나타났다. 또한 MRI 사진에 의해서 확인된 바에 의하면, 관절원판의 변위와 관절원판의 파괴, 피질골의 침식이나 증식 등의 소견이 류마티스성 관절염 환자에게서 유의하게 높은 빈도로 나타났다. 결론적으로 류마티스성 관절염 환자에서 측두하악장애의 발생빈도가 매우 높고 관절의 구조적 변화도 일반적인 측두하악장애 환자에 비해 더 심하게 나타남을 알 수 있었다.
