Tetanus is a fatal disease caused by the infection Clostridium tetani found in animal feces and soil. It is a vaccine-preventable disease and rarely occurs in developed countries. However, approximately 30 cases still occur annually in South Korea. Tetanus, commonly called lockjaw, cause contraction of the masseter muscles in the early stage, resulting in trismus as the first symptom. As it progresses, spasm extends to various muscles in the face, neck, shoulder, and back, leading to distorted facial expression, dysphagia, backward arching of the body, dyspnea, and even death. Early diagnosis of tetanus is critical because it can quickly become fatal if left untreated. We present a case of trismus caused by tetanus and emphasize the importance of early diagnosis of acute trismus.

Horner's syndrome as a complication of orthognathic surgery is given little attention of head and neck surgery and is a relatively benign and transient condition. A 18-year-old male referred to our department with long and anteriorly projected chin. The cephalometric evaluation revealed a skeletal Class III relationship. A 10-mm setback of the mandible to eliminate Class III relationship and 4-mm vertical reduction genioplasty were performed. Three weeks after operation, the patient was recognized anhidrosis in left face and the head, and ptosis of left eye. The trauma to cervical sympathetic nerve during left sagittal split ramus osteotomy was thought to be the cause of Horner's syndrome. Patient was treated by dermatologic and opthalmologic care.

The author has studied on the clinical features and symptomatology of 97 MPDS patients, who visited the Dept. of Dentistry, Kyungpook National University, from January to September in 1982. The results were as follow : In age and sex distribution of patients in this population, the third decades appeared to have the highest prevalence and the male to female ratio was almost 1 to 2.23. As to occupation, students and housewives were revealed to have the highest incidence of MPDS. The chief complaints of patients were pains, TMJ noises, and limitation of mouth opening in order of frequency, and the most prevalent site of symptom was that of preauricular area. In symptom sequence, the majority of initial symptoms were TMJ noise and pain but limitation of mandibular movement was progressively developed, regardless of nature of early symptoms. Chronic unfavorable oral habits were found to be the most possible predisposing factors in this study. The average maximum interincisal distance was $38.13\pm10.00mm$ in males and $30.73\pm8.75mm$ in females, and a deviation of mandible during mouth opening was observed in 60.8% of patients. In TMJ signs, tenderness of the TMJ to palpation was found in 60.8% of patients and TMJ noise was audible in 50.5% of patients with a stethoscope. The muscles of masticatory system were palpated according to usual methods, and a significant indidence of muscular tenderness was present, with the lateral pteygoid muscles being most frequently involved, followed by masseter, medical pterygoid and temporalis muscles.

Leiomyosarcoma(LMS) is a malignant tumor from smooth muscle origin that arises most commonly in the gastrointestinal tract and uterus, but rarely in the oral and maxillofacial area which lacks smooth muscles. 63 cases of oral LMS have been reported, especially LMS that occurred in the mandibular gingiva is only 2 cases. Major symptom of oral LMS is painful or painless swelling. Besides it, oral LMS has no specific characteristics. So it is difficult to diagnose the case as LMS of the oral cavity. Certain cases report that LMS of the oral cavity was misdiagnosed as periodontitis and the patients were treated with unnecessary procedures. Conventional treatment of LMS is the radical surgical excision. LMS that is infiltrative and very malignant has poor prognosis despite of well-circumscribed boundary. LMS of the oral cavity is often recurred, has high rate of distant metastasis and 5-year-survival rate is as low as 23%. This article reports LMS of the mandibular gingiva that treated with surgical intervention, had local recurrence and metastasis to the lymph node after 16-month's follow-up examination.

Objectives: This study aims to determine the relationship between sedentary behavior and oral health factors in adolescents. Methods: Based on the data from the online survey on youth health behaviors, general characteristics, sedentary behavior was classified as practiced for less than 2 hours, and not practiced for more than 2 hours, and oral health was classified brush teeth after lunch, sealant, oral symptoms. The analysis methods were complex frequency analysis, complex chi-square test, and complex logistic regression analysis. Results: In case of brush teeth after lunch during the week, those who practiced it was 1,025 times higher than those who did not practice it, and in the case of oral symptoms practice was 0.915 times lower than not practice. As a result of adjusted general characteristics, for brushing teeth after lunch during the week, practice was 1,090 times higher than no practice. Conclusions: The relationship between sedentary behavior and oral health behavior and oral symptoms could be confirmed. Therefore oral health promotion programs according to sedentary behavior are needed to promote oral health for adolescents.

Objectives: This study aimed to determine the relationship between hours of smartphone use and oral disease symptoms in Korean adolescents. Methods: In this study, data from the 2022 Youth Health Behavior Online Survey were used. The final analysis was conducted on students who responded that they have used a smartphone (N=50,375). Chi-squared test and multivariate logistic regression analysis were used to analyze the relationship between oral disease symptoms and smartphone use time (p<0.05). Results: Consequent to examining the effect of smartphone use on oral disease symptoms, it was found that oral symptoms, such as pain during chewing and tingling throbbing, increased as smartphones were used for >4 h (p<0.05). Additionally, oral symptoms, such as gingivalgia bleeding and bad breath, appeared to increase as smartphones were used for >6 h (p<0.05). However, using smartphones for <0-2 h or 2-4 h had no effect on oral disease symptoms. Conclusions: In adolescents, oral disease symptoms increased significantly with increasing hours of smartphone use. Therefore, adolescents should be guided so that they use smartphones for <2 h or >4 h. Moreover, guidance on forming the habit of tooth brushing after eating food should be provided to prevent oral disease symptoms.

본 연구의 목적은 서울시 돌봄 서비스 노동자들의 직무스트레스와 정신건강 요인이 구강 증상에 미치는 영향에 대하여 살펴보고자 한다. 연구 방법은 돌봄 서비스 노동자 150명을 대상으로 7월 24일부터 8월 6일까지 설문조사를 시행하였다. 조사항목으로는 직무스트레스, 정신건강(신체증상, 불안, 불면), 주관적 구강 증상을 조사하였으며, 연구 결과 다음과 같다. 직무스트레스(p=0.001)는 구강 증상에 유의한 영향을 주는 것으로 나타났다. 또한, 신체증상(p<0.001), 불안 증상(p<0.001), 불면 증상(p<0.001) 모두 구강 증상에 유의한 영향을 주는 것으로 나타났다. 위험 요인 중 신체 증상이 구강 증상에 가장 큰 영향을 미치는 것으로 나타났다. 또한 직무스트레스, 불안 증상, 불면 증상, 구강 증상의 상관성 결과, 직무스트레스가 증가할수록 신체 증상(p<0.001), 불안 증상(p<0.001), 불면 증상(p<0.001), 구강 증상(p<0.01)이 모두 증가하는 양의 상관성을 나타냈다. 돌봄 서비스 노동자들은 돌봄 대상자를 신체적·정신적으로 보살펴야 하는 업무를 수행하므로 육체적·심리적 노동력 소진이 크다. 자신의 건강과 구강건강 상태가 좋아야 업무수행력을 높일 수가 있기에 노동자들의 정신건강을 위한 제도적 확대 방안이 필요하며, 구강건강 증진을 위한 맞춤별 구강보건교육 프로그램 도입이 매우 필요하다고 사려된다.

This is a case report about patient who had suffered from degenerative joint disease and treated by TMJ reconstruction with condylar prosthesis. The patient visited Korea University An-am hospital on 2007 complaining symptom about both TMJ pain, mouth opening limitation and open bite. From CT view there was severe resorption of both condylar head, therefore condylar prosthesis reconstruction was planned. After 3D RP model analysis for preparation, the patient was operated under general anesthesia for condylar prosthesis reconstruction and the symptom was alleviated. (increased mouth opening, reduced anterior open bite, full mouth occlusal contact achieved) Follow up was carried out monthly, but after this, patient refused follow up. After 26 months from the operation, the patient revisited for anterior open bite. In clinical evaluation, occlusal contact was remained, but anterior open bite was relapsed. From cephalometry analysis, severe resorption of glenoid fossa was found. Therefore, Autogenous disc reconstruction with alloplastic material was planned on August 2009. After another surgery, condylar prosthesis was regained its normal position in glenoid fossa, and occlusion was recovered properly.
