An Epidemiologic study was carried out on 77 TMD patients with degenerative joint disease who had visited the Orofacial Pain Clinic in Pusan National University Hospital. Al subjects were interviewed and examined clinically and radiologically using a standardized examination form. As related to gender and duration, subjective and objective sysmptoms in DJD patients were studied. The obtained results were as follows : 1. There were much more patients in the twenties or thirties, women and histories such as chronic duration and microtrauma. 2. Most patients responded positively more often to the questions of jaw function, unilateral chewing in habits, poot appetite and depression in behavioral response and shoulder pain in worsening prognosis 3. While the most common reasons for treatment were pain, noise, and limitation of opening, the associated symptoms such as headache, neckache, earache, jaw dysfunction, neck dysfunction, acute bite change and dizziness, ringing or fullness in the ears as secondary CNS excitatory effects were complained. 4. Opening the mouth in 25 to 40mm, soft end feel and deflective incisal pathway were seen and more tenderness to lateral or dorsal capsule of joint than intra or extra oral muscles were complained. 5. While there appeared no click, crepitus and single click in acute group, in chronic group, crepitus, single click and no click appeared in order of sequence. 6. Tomogram or bone scan revealed more bony changes than panorama and transcranial view.

Purpose: To investigate the relationship between headache and sleep by evaluating sleep quality, daytime sleepiness, and specific features related to sleep-disordered breathing (SDB). Methods: One hundred one subjects with headache and 118 healthy controls were enrolled. To collect various information on headache attacks, headache group completed self-reported questionnaire about the characteristics of headache attacks and the migraine disability assessment (MIDAS) questionnaire. The subjective quality of sleep was evaluated in all of the subjects using the Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale (ESS). In addition, the following specific features of sleep were evaluated in 28 subjects selected randomly from each group: apnea-hypopnea index (AHI), prevalence of SDB, nocturnal oxygen saturation (SaO2), and oxygen desaturation index (ODI) as measured using a portable monitoring device. Results: The global PSQI and the prevalence of poor sleeping (global PSQI >5), ESS scores and the prevalence of daytime sleepiness (ESS score >10) were significantly higher in the headache group (both p<0.0001, respectively). The mean scores on the numerical rating scale and the MIDAS were significantly higher in the poor-sleeper group than in the good-sleeper group (p=0.0347 and p=0.0016, respectively). The global PQSI and prevalence of daytime sleepiness were significantly higher in the chronic-headache group than in the acute-headache group (p=0.0003 and p=0.0312, respectively). Conclusions: There is a significant association between headache and sleep. Especially, severity and chronicity of headache were significantly associated with sleep quality and daytime sleepiness.

Purpose: This study aimed to investigate whether and how the biopsychosocial features of myofascial pain (MFP) differ from those of local myalgia (LM) in temporomandibular disorder (TMD). Methods: Patients with TMD were retrospectively evaluated using the Diagnostic Criteria for TMD. All patients completed a series of self-administered questionnaires on pain severity and pain interference (Brief Pain Inventory, BPI), pain disability (Graded Chronic Pain Scale, GCPS), psychological distress (Symptom Check List-90-Revised, SCL-90R), pain cognition (Pain Catastrophizing Scale, PCS), and subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI). Among all the TMD diagnoses, muscle pain was classified into the MFP group and LM group. Results: This study included 917 patients with myalgia (MFP: 266, LM: 651). Significant differences were observed in the female ratio (78.9% for MFP, 60.9% for LM, p<0.001) and the mean pain duration (MFP: 25.3 months, LM: 15.8 months, p=0.001) between the two groups. Patients with MFP exhibited higher pain severity (p=0.003) and pain interference (p<0.001) of BPI than those with LM. Furthermore, the global scores of the PCS (p<0.001) and PSQI (p<0.001) were higher in the MFP group than in the LM group. The MFP group had higher global symptom index (p=0.017) and five subscales of the SCL-90R than the LM group. Compared with the LM group (33.4%), the greater proportion of high disability of GCPS was observed in the MFP group (44.9%) (p<0.001). Multiple regression analysis revealed that sex (p=0.002), pain duration (p=0.019), pain disability (p=0.010), and subjective sleep quality (p=0.008) significantly differed between the two groups. Conclusions: The findings of this study indicated that MFP presents a higher biopsychosocial burden than LM in TMD.

Burning mouth syndrome (BMS) is a chronic idiopathic orofacial pain. BMS is currently classified as a neuropathic pain condition, but it is difficult to pinpoint the precise neuropathic mechanisms involved in each patient. It is challenging to complete the cure for BMS. Clinicians should treat BMS patients based on evidence. There is pharmacological and non-pharmacological therapy in the treatment modalities of BMS. The provision of objective information and reassurance as part of cognitive behavioral therapy is critical in the treatment of BMS. This paper will review the evidence-based treatment of BMS and discuss what we need to do.

Purpose: Temporomadibular disorders (TMDs) can result in chronic pain, which is often associated with psychological and sleep disturbance. Increased levels of psychological and sleep impairments are often related with poor treatment outcomes. The purpose of the present study was to evaluate clinical features, psychological profiles and the prevalence of clinical insomnia in TMD patients with chronic pain and to suggest an effective treatment approach. Methods: A total of 200 TMD patients who had visited the Pusan National University Hospital dental clinic for treatment of their pain were recruited from June 2018 through December 2019. TMD patients were classified into an acute (n=100) and chronic (n=100) group and compared the clinical symptoms. The primary diagnosis of TMD were categorized as TMD with joint pain group (TMD_J), TMD with muscle pain group (TMD_M) and TMD with joint-muscle mixed pain group (TMD_JM). Self- report measures of sleep quality and psychological profiles were evaluated via the Insomnia Severity Index (ISI) and the Korean Stress Response Inventory (SRI). Independent t-tests, Mann-Whitney U-tests, and chisquared test were used for the statistical analysis. Results: Chronic TMD patients showed higher pain intensity, as well as higher prevalence of related symptoms (headache, musculoskeletal pain) and myogenous pain. They also had significantly higher scores in all SRI parameters and a higher percentage of clinical insomnia than acute TMD patients. Conclusions: Based on the above results, psychological profiles and sleep quality assessments are necessary to provide essential data that will allow for improved treatment of chronic TMD patients.

The present study investigated the role of spinal glutamate recycling in the development of orofacial inflammatory pain or trigeminal neuropathic pain. Experiments were carried out on male Sprague-Dawley rats weighing between 230 and 280 g. Under anesthesia, a polyethylene tube was implanted in the atlanto-occipital membrane for intracisternal administration. IL-$1{\beta}$-induced inflammation was employed as an orofacial acute inflammatory pain model. IL-$1{\beta}$ (10 ng) was injected subcutaneously into one vibrissal pad. We used the trigeminal neuropathic pain animal model produced by chronic constriction injury of the infraorbital nerve. DL-threo-${\beta}$-benzyloxyaspartate (TBOA) or methionine sulfoximine (MSO) was administered intracisternally to block the spinal glutamate transporter and the glutamine synthetase activity in astroglia. Intracisternal administration of TBOA produced mechanical allodynia in naïve rats, but it significantly attenuated mechanical allodynia in rats with interleukin (IL)-$1{\beta}$-induced inflammatory pain or trigeminal neuropathic pain. In contrast, intracisternal injection of MSO produced anti-allodynic effects in rats treated with IL-$1{\beta}$ or with infraorbital nerve injury. Intracisternal administration of MSO did not produce mechanical allodynia in naive rats. These results suggest that blockade of glutamate recycling induced pro-nociception in na?ve rats, but it paradoxically resulted in anti-nociception in rats experiencing inflammatory or neuropathic pain. Moreover, blockade of glutamate reuptake could represent a new therapeutic target for the treatment of chronic pain conditions.

수면과 통증과의 상호 작용은 여러 연구들에 의해 밝혀져 왔고 그 기전에 대해서는 현재도 다양한 연구들이 이루어지고 있으나 앞선 연구들은 대부분 류마티스질환이나 섬유근통과 같은 전신적 질환을 갖는 환자들을 대상으로 하고 있으며 측두하악질환을 포함한 안면통증 환자들을 대상으로 한 연구는 거의 없다. 본 연구에서는 구강내과, 턱관절 및 안면통증 클리닉에 내원한 229명의 측두하악장애 환자를 대상으로 수면설문 및 간이 수면검사를 시행하여 측두하악장애 환자에서의 통증양상과 수면과의 관계를 분석해 보았다. 1. PSQI설문에 의한 수면의 질 평가에서는 통증이 있는 측두하악장애 환자군이 통증이 없는 군에 비하여 수면의 질이 저하된 환자의 비율이 높게 나타났으며 수면의 질이 저하된 정도도 더 크게 나타났다. 특히 통증이 6개월 이상 지속된 만성 측두하악장애 환자에서는 뚜렷하게 수면의 질 저하가 나타났다. 2. ESS설문에 의한 주간졸리움증의 평가에서도 통증이 있는 측두하악장애 환자군이 통증이 없는 군에 비하여 주간졸리움증을 호소하는 환자의 비율이 더 높았으며 6개월이상 통증이 존재하는 만성 측두하악장애 환자군에서 더욱 높았으며 주간 졸리움증의 정도 또한 더 심하였다. 특히 통증이 있는 만성 측두하악장애 환자군 중에서 global PSQI가 5이상인 수면이 저하되어 있는 환자에서만 평균 ESS 수치가 10이상을 기록하여 주간졸리움증의 판단 기준에 해당하였다. 3. 통증의 강도에 따른 수면의 질과의 관련성이나 주간졸리움증과의 관련성의 결과는 상관관계가 없는 것으로 나타났다. 4. 수면관련 호흡장애를 검사하기 위한 간이수면검사기기인 ApnealinkTM를 사용하여 수면시 호흡상태를 측정한 결과 검사를 시행한 총 19명의 환자중 1명만이 수면무호흡저호흡지수(AHI)>5인 수면무호흡증을 나타내었다. 다른 만성통증질환과 마찬가지로 만성통증을 나타내는 측두하악장애 환자에서도 수면의 질이 저하되었으며 주간졸리움증이 심한 것으로 나타났다. 수면장애가 있는 경우 통증에 대한 역치를 낮추고 통증과 수면장애가 순환적인 상호작용을 일으켜 치료를 어렵게 하므로 측두하악질환을 진단하고 관리하는 데 있어 수면설문지를 이용한 수면 상태의 평가는 유용할 것으로 사료된다. 특히 치료가 장기화 되고 치료에 대한 반응이 적은 환자에게 있어서 수면장애에 대한 평가가 반드시 이루어져야 할 것으로 사료된다. 간이수면검사기기 또한 치과에서 진단하기 어려운 호흡관련 수면장애의 초기 검진 시 유용한 도구가 되리라 생각되는 바이다.
