Background: Although magnetic resonance imaging is accurate, it is expensive to measure the movement of temporomandibular joint. The three-dimensional (3D) motion analysis system is an inexpensive measurement tool. Objects: This study examined the reliability of quantifying the mouth opening and lateral mandibular shift and differences between individuals with and without temporomandibular disorder (TMD) using the hygienic method of surface markers on the skin with 3D ultrasound-based motion analysis. Methods: This study included 24 subjects (12 with and 12 without TMD). Temporomandibular joint motion during mouth opening was recorded using two surface markers with 3D ultrasound-based motion analysis. An intraclass correlation coefficient [ICC (3,k)] was used to confirm the intrarater reliability of quantifying kinematic temporomandibular joint motion, and an independent t-test was used to evaluate differences in maximal mouth opening and lateral mandibular shift between the two groups. Results: Assessment of mouth opening and lateral mandibular shift showed excellent test-retest reliability with low standard error of measurement. The lateral mandibular shift and opening-lateral mandibular shift ratio were significantly increased in the TMD group during maximum mouth opening (p<.05). However, no significant difference in maximal mouth opening was observed between the groups with and without TMD (p>.05). Conclusion: This hygienic and simple surface marker method can be used to quantify the mouth opening and lateral mandibular shift at the end-range of mouth opening. The TMD group showed an increased lateral mandibular shift movement at the end-range of mouth opening. The lateral mandibular shift movement can be regarded as a symptom in the diagnosis and treatment of TMD.

Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

Headaches are one of the most common conditions associated with temporomandibular disorder (TMD). In the present paper, we evaluated the relationship between headache and TMD, determined whether headache influences the symptoms of TMD, and reported two cases of TMD accompanied by headache. Our practical experience and a review of the literature suggested that headache increases the frequency and intensity of pain parameters, thus complicating dysfunctional diseases in both diagnostic and treatment phases. Therefore, early and multidisciplinary treatment of TMD is necessary to avoid the overlap of painful events that could result in pain chronicity.

Temporomandibular disorders (TMD), involving the masticator system of temporomandibular joint (TMJ) and masticator muscle, can be characterized with the cardinal signs and symptoms of jaw pain, noises and limitation of mandibular range of motion. However, TMD requires differential diagnosis due to its heterogeneous characteristics with various causes despite the similar clinical profiles. Oral cancer involving TMJ and the masticator system, although infrequent, can be one of these causes and should be considered one of the most life-threatening disease mimicking TMDs. This report introduces a case of masticator space tumor originally diagnosed as TMD in a 73-year-old Korean female with previous history of brain tumor. The clinical signs and symptoms closely mimic that of TMD which may have disrupted differential diagnosis. We discuss here key points for suspecting TMDs of secondary origin, namely, that of cancer and the implications it has on dental clinicians.

Perforation of articular disc of temporomandibular joint is a unusual condition and diagnosed through magnetic resonance imaging (MRI), arthrography or arthroscopic surgery. We attempted to investigate the suspicious findings of articular disc perforation through examination commonly used in temporomandibular disorder (TMD) patients. We retrospectively analyzed the clinical and imaging findings of five TMD patients whose articular discs were perforated based on MRI. The most meaningful finding was the abnormal width of the joint space in cone-beam computed tomography. Thus, the clinician should perform a thorough assessment of the joint space in TMD patients and conduct additional investigation to determine what caused the abnormal joint space.

본 연구는 측두하악관절의 개구성 과두걸림과 골격적 특성 사이의 연관성을 분석하고자 개구성 과두걸림 환자를 대상으로 측두두부방사선 사진과 횡두개촬영 방사선 사진을 이용하여 두개골의 골격적 특성 및 관절 융기의 기울기를 비교 분석하였다. 개구성 과두걸림 환자를 환자군으로 하고 개구성 과두걸림은 없지만 측두하악장애 연구진단 기준(Research Diagnostic Criteria for Temporomandibular Disorder; RDC/TMD) Axis I에 따라 측두하악장애으로 진단된 환자를 측두하악장애 환자군, 개구성 과두걸림과 측두하악장애가 모두 없는 정상 환자를 정상군으로 설정하고 순차적으로 수집된 환자군 50명과 성별 및 연령이 일치하도록 무작위로 측두하악장애 환자군과 정상군, 각각 50명의 임상기록을 선별하였다. 측두하악장애에 영향을 줄 수 있는 관절염이나 외상의 병력, 악안면 기형, 악안면 수술 병력이 있는 환자는 모두 제외하였다. 세 군의 측두두부규격방사선 사진과 횡두개촬영 방사선 사진을 분석하여 골격적 특성과 관절 융기의 기울기를 측정하였다. 두개골과 하악과의 골격적 특성을 나타내는 측두두부방사선 사진을 분석한 결과 개구성 과두걸림이 있는 환자군에서 하악의 전후방적 위치를 나타내어주는 saddle angle이 더 작은 것으로 나타났으며 이는 두개골에 대해 하악이 더 전방으로 위치하고 있음을 나타낸다. 또한 횡두개촬영 방사선 사진상에서는 개구성 과두걸림 환자군이 측두하악장애 환자군과 정상군보다 관절융기의 기울기가 더 크게 관찰되었다. 이러한 결과는 두개골에 대해 측두하악관절이 더 전방으로 위치하고 관절 융기가 더 급한 경사를 가질 경우 개구성 과두걸림이 발생할 가능성이 더 크다는 것을 의미한다.

Purpose: This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. Materials and Methods: The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the $X^2$ test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Results: Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p<0.05). However, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Conclusion: Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

An association between psychological factors and temporomandibular disorders (TMD) has been extensively explored for over 40 years, and a high prevalence of depression and somatization has been consistently reported in patients with TMD. Current evidence suggests that patients' somatic awareness can serve as a primer for TMD incidence and further contribute to the transition to chronic pain. However, the current understanding of somatization from a medical perspective is limited. The best way to address patients with TMD pain who have somatization is also unclear. Therefore, this paper aims to provide an overview of somatization in the context of pain psychology and address its clinical implications in the context of TMD pain.
