Objectives: Headache is the most common complaint of patients suffering from temporomandibular joint disorders (TMDs). Thus, temporomandibular joint (TMJ) examinations maybe necessary in patients with headache. Considering the high prevalence of bruxism and TMDs in patients with headache the effects of conservative TMD treatment on headache should be assessed. Materials and Methods: Patients were questioned about headaches in the past three months. Those responding affirmatively to this question were examined for TMD and bruxism. After the examinations, 219 patients remained in the study and received self-management instructions. Patients were requested to modify oral habits except when eating or sleeping. The degree of pain (visual analogue scale), headache disability index (HDI), frequency of headaches (FH) per month and TMD intensity were evaluated. Results: The median levels of pain, HDI, FH, and TMD intensity were 8, 44, 8, and 7, respectively, before modifying oral habits and decreased to 4, 24, 2, and 3, respectively, after intervention. These decreases were statistically significant. Conclusion: Having patients maintain free space between the teeth and relax muscles can be an efficient method to treat headache and TMD, especially when repeated frequently.

Background: The options for stabilization appliance therapy for masticatory muscle pain include soft occlusal and hard stabilization appliances. A previous study suggested that hard stabilization appliance therapy was effective for patients with local myalgia who developed long facets on their occlusal appliances. The objective of this study was to identify patients in whom a soft occlusal appliance should be used to treat masticatory muscle pain by analyzing the type of muscle pain present and patient factors that influenced the effectiveness of this treatment. Methods: The study included 42 patients diagnosed with local myalgia or myofascial pain according to the Diagnostic Criteria for Temporomandibular Disorders Diagnostic Decision Tree. The analysis of patient factors included variables believed to be associated with temporomandibular disorders. First, a temporary screening appliance was used for 2 weeks to assess each patient for bruxism during sleep. Soft appliance therapy was then started. For each patient, the effectiveness of the appliance was evaluated according to the intensity of tenderness during muscle palpation and the treatment satisfaction score at one month after starting treatment. Results: Data from 37 of the 42 patients were available for analysis. Twenty-five patients reported satisfaction with the appliance. In logistic regression analysis, the odds ratio for reduction of facet length was 1.998. Nineteen patients showed at least a 30% improvement in the visual analog scale score. The odds ratio for local myalgia was 18.148. Conclusion: Soft appliance therapy may be used in patients with local myalgia. Moreover, patients who develop short facets on the appliance surface are likely to be satisfied with soft appliance therapy. Soft appliance therapy may be appropriate for patients with local myalgia who develop short facets on their occlusal appliance.

The usages of botulinum toxin were most commonly for the treatment of spasmodic dysphonia in the otolaryngology field. It has been not only widely used in otolaryngology-Head Neck surgery but also plastic surgery, ophthalmology, rehabilitation medicine, and orthopedics. Now botulinum toxin is used such as blepharospasm (excessive blinking), strabismus, cosmetic, muscle spasms, upper motor neuron syndrome, severe primary axillary hyperhidrosis (excessive sweating), cervical dystonia (spasmodic torticollis), chronic migraine, bruxism, and achalasia. The indication of this drug still gradually expanding with the times. In this articles, the author will demontrate how to use the botulinum toxin for treating cricopharyngeal spasm, arytenoid dislocation, sialocele, Frey syndrome, contact granuloma, bilateral vocal fold paralysis, and mutaional falsetto instead of conventional surgical treatment.

We tend to consider only static occlusion such as molar relationship, canine key, and interdigitation at finishing stage. Of course, this static occlusion is important for post-orthodontic stability. But we should remember that mandible is always on the move during its various functions. If no pressure or too much pressure is put on during its functions, untoward tooth movement could occur. And tooth mobility, periodontitis, wear facet, bruxism, and far worse temporomandibular disorder could occur. After many studies have been done on what is a desirable occlusal scheme to strengthen post-orthodontic stability, today, "mutually protective occlusion" is recommended. If an orthodontist does not have understanding about this occlusal scheme during orthodontic treatment, the following conditions will be resulted after orthodontic treatment. I. Centric discrepancy 1. centric prematurity 2. sunday bite 3. molar fulcrum II. Eccentric discrepancy 1. posterior interference 2. anterior interference If we have deep understanding about these discrepancies that can happen after orthodontic treatment and their causes, corrections, and especially preventions against them, post-orthodontic stability could be strengthened and further temporomandibular disorder could be prevented.

14 patients, whose were attacked pain dysfunction syndrome of temporomandibular joint in Dental College Infirmary, Seoul National University from June 1970 to Dec. 1971, were examined regarding to clinical observation and electromyographical analysis. This paper established the followings: 1. Especially young female was more frequently attacked by pain dysfunction syndrome of Temporomandibular joint. 2. It is suggested that most of joint pain was occurred initially in opening mouth and forcible bite, and left side is more attacked than right side. 3. It was possible that this dysfunction can be occurred by open-bite, premature contact and ill-fitting prosthetic restoration. 4. Hoby, habit and bruxism as causal factors are not markedly related with this dysfunction. 5. Pain attacked regions, in most patients, are preauricular, joint itself, infra-auricular, cervical and external auditory meatus region. 6. In electromyographical studis, the musle activities of affected side of pain dysfunction syndrome are more strong than that of opposite side.

Temporomandibular joint osteoarthritis (TMJ OA) causes destruction of the temporomandibular joint (TMJ) and can lead to occlusal changes such as anterior open bite in some patients. Consequently, these patients may experience difficulty in chewing food items and exhibit abnormal functional habits such as bruxism, preventing healing of the TMJ condyles. Treatment protocols include the use of traction appliances to reduce stress on the condyles. Unstable occlusions can lead to weakness of the masticatory muscles which, in turn, worsen the occlusal changes and complicate pain management. Therefore, the current study evaluated the condition of the masseter muscle using ultrasonography and educated patients on the execution of gum-chewing exercises for muscle strengthening. It also aimed to assess the effects of traction appliances and strengthening exercises on the masticatory muscles of patients with occlusal changes caused by TMJ OA.

본 연구에서는 치아교모도에 의한 연령감정법을 이용하여 측두하악장애환자의 치아연령을 일반 정상인과 비교하고, 측두 하악장애환자의 구강습관이 치아교모에 미치는 영향을 조사하고자 하였다. 단국대학교 치과병원 구강내과에 측두하악장애를 주소로 내원한 환자 65명을 실험군으로 하고, 측두하악장애증상이 없는 정상인 22명을 대조군으로 하였다. 문진 및 설문조사를 통해 대상자의 구강습관을 조사하였으며, 임상 및 방사선검사후 치아교모도를 조사하여 치아연령을 산출하였다. 실험군과 대조군의 치아교모도의 차이 및 각각의 구강습관이 치아교모에 미치는 정도를 분석하기 위해 t-test 및 one-way ANOVA, multiple comparison t-test를 이용하였다. 연구 결과 대조군에 비해 실험군의 치아교모도가 유의성 있게 증가했으며, 조사된 구강습관중 이갈이, 이악물기, 식사습관(단단하고 질긴 음식)순으로 치아교모도에 영향을 주었다. 따라서, 측두하악장애환자의 연령감정시 증가된 치아교모도에 의해 나타날 수 있는 실제 연령과의 차이를 고려해야 한다. 특히, 20-30대의 연령감정시에 측두하악장애환자의 경우 약 3.5세, 이중 특히 이갈이의 습관이 있는 경우에는 약 5.3세의 감정연령의 증가가 있을 수 있음을 감안해야 한다. 또한, 측두하악장애환자는 일반 정상인보다 치아 교모가 심한 경향이 있고 이는 치아와 턱관절에 더 많은 하중이 가해지고 있음을 의미하므로 측두하악장애환자의 치료시에는 반드시 이러한 요인을 제거하는 치료술식을 병행해야 할 것으로 사료된다.

Purpose: The purpose of this study is to determine factors influencing the duration of occlusal appliance (OA) treatment for patients with temporomandibular joint (TMJ) internal derangement. Methods: Ninety patients were included for this study, who satisfied the following including criteria: (i) those who were diagnosed as disc displacement of TMJ by taking magnetic resonance imaging (MRI) and (ii) those who were finished OA treatment. The subjects were classified into three groups according to the period of OA treatment: (i) early response group (<6 months), (ii) moderate response group (6 months-1 year), and (iii) delayed response group (>1 year). Demographic data, data from chief complaints and past history of temporomandibular disorder, data from clinical examination and diagnostic imaging including panoramic view and TMJ MRI were compared among groups. One-way ANOVA and chi-square analysis were used to test statistical significance. Results: There were no significant differences in demographic data, data from chief complaints and TMJ imaging. However, only the prevalence of oral parafunctional habits including bruxism, clenching, and unilateral chewing showed significant differences among groups. Conclusions: Oral parafunctional habits could be factors to influence the duration of OA treatment in the patients with TMJ internal derangement.
