Abstract

Objectives: This study aimed to assess the characteristics of temporomandibular disorder (TMD) symptoms and to determine the correspondence between TMD symptoms and clinical examination findings. Material and methods: A total of 218 patients (143 females and 75 males; age=$31.3{\pm}14.0$) were enrolled in this study who completed a questionnaire and underwent a clinical examination and radiographic assessment. Patients were asked about all the symptoms and complaints, including onset or duration, and locations of the symptoms. Clinical examination included amounts of mouth opening, palpable temporomandibular joint (TMJ) sounds, and tenderness to palpation of the TMJ and all masticatory muscles. Tenderness scores obtained from palpation of the masticatory system were summated to define the variables for further analysis. Results: Pain was the most frequently reported symptom (78.9%), followed by joint sounds (45.4%), and limitation in mouth opening (17.0%). Jaw pain comprised 91.9% of pain complaints. The subjective intensity of jaw pain was low to medium in most patients (93.7%), but it was poorly correlated with the sum of tenderness scores of the TMJ and masticatory muscles (Kendall tau = 0.084). In contrast, the side in which pain was reported by patients was well associated with the clinical examination results (pain of the right side, p < 0.001, and left side, p < 0.001). There was moderate agreement in TMJ sounds between the side identified by patients as symptomatic and clinical examination findings (kappa = 0.482). Finally, patients who complained of restricted mouth opening showed about a 10 mm less opening in all three measurements, compared to other patients (p < 0.001). Conclusion: The most frequent symptoms reported by TMD patients were jaw pain, TMJ sounds, and mouth opening limitation. The side of jaw pain, the side of TMJ sounds, and the presence of opening limitation were highly concordant between symptom reports and examination findings.

목적: 측두하악장애 환자에서 다양한 증상의 양상을 평가하고, 측두하악장애 증상과 임상검사 소견 간의 일치 정도를 평가하고자 하였다. 재료 및 방법: 총 218명의 환자(여자 143명, 남자 75명, 평균 연령 $31.3{\pm}14.0$세)를 대상으로 하였으며, 설문지 작성, 임상검사 및 방사선 검사를 수행하였다. 증상의 발생 시기 및 위치를 포함하여 주소와 관련된 모든 증상을 문진하였다. 임상검사로는 개구량 측정, 악관절 잡음 촉진, 악관절 및 저작근 촉진 검사를 하였다. 촉진에 의한 압통검사 결과수치를 이용하여 압통점수합을 구하였다. 결과: 통증이 가장 흔한 증상이었으며(78.9%), 다음으로 악관절 잡음(45.4%), 그리고 개구 제한(17.0%) 순으로 흔하였다. 턱의 통증이 통증 증상 부위의 91.9%를 차지하였다. 주관적인 턱의 통증 강도는 대부분의 환자에서 낮거나 중등도였으며 (93.7%), 이것과 악관절과 저작근의 압통 점수 합과의 상관성은 낮았다(Kendall tau = 0.084). 이와 대조적으로 환자가 보고하는 통증의 좌우측 위치는 임상검사 결과와 관련성이 높았다(우측 통증 p<0.001, 좌측 통증 p<0.001). 악관절 잡음은 환자가 증상으로 인지하는 측과 임상검사 소견 간에 상당한 일치를 보였다(kappa = 0.482). 개구제한을 호소하는 환자는 세가지 개구량 측정값 모두에서 그렇지 않은 환자보다 약 10 mm가 적은 개구량을 보였다(p<0.001). 결론: 턱의 통증, 악관절 잡음 및 개구제한은 측두하악장애 환자의 주소와 관련된 주요한 증상이었다. 환자가 보고하는 통증 부위와 악관절 잡음 및 개구제한이 임상검사 결과와 중등도 내지 높은 일치성을 보임으로서 가장 신뢰할 만한 항목으로 평가되었다.
