MPDS 患者의 臨床的 樣相

崔在甲,鄭雲夏 慶北大學校 齒科大學 1984 慶北齒大論文集 Vol.1 No.1

The author has studied on the clinical features and symptomatology of 97 MPDS patients, who visited the Dept. of Dentistry, Kyungpook National University Hospital, 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 ± 10.00 mm in males and 30.73 ± 8.75 mm 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 incidence of muscular tenderness was present, with the lateral pterygoid muscles being most frequently involved, followed by masseter, medial pterygoid and temporalis muscles.

This study evaluated whether substantial airflow resistance changes occurred by changing jaw position in normal and snoring subjects. A case-control design was utilized to assess group differences. Subjects included 11 snoring patients and 10 non-snoring subjects. Airway resistance was assessed using a whole body plethysmograph. Subjects in this study had their mouth opening standardized to a position of 7 mm of vertical separation and the resistance was measured under the following conditions; normal jaw position and 2/3 maximum protrusive jaw position. The results were as follows : 1. The airway resistance was higher in snoring group than in non-snoring group. 2. Both groups had a significant decrease in their airflow resistance upon jaw protrusion. In conclusion, these data document that airflow resistance can be significantly influenced by jaw positioning. Moving the jaw in a protrusive position produced reduction of resistance.

수면과 치의학

Dental sleep medicine is an up-and-coming discipline of dentistry, more specifically an offshoot of oral medicine. It traditionally focuses on sleep-related breathing disorders, such as snoring and bstructive sleep apnea. However, everyday practice shows that also other sleep disorders touch on dentistry, including orofacial pain, xerostomia, and bruxism. Therefore, a new definition has been formulated for dental sleep medicine as following; ‘Dental sleep medicine is the discipline concerned with the study of the oral and maxillofacial causes and consequences of sleep-related problems’. It is this article’s aim to further introduce the emerging discipline of dental sleep medicine to all professionals working in sleep medicine. This article briefly describes the different dental sleep disorders with special focus on the more remarkable associations between orofacial pain and sleep. "이상에서 살펴본 바와 같이 수면과 치의학은 매우 밀접한 관계에 있으며, 치과수면의학의 관심 분야가 점차 확장되고 있음을 알 수 있다. 또한 구강안면통증, 수면이갈이, 폐쇄성 수면무호흡증의 인식과 관리에 있어서 치과의사의 역할이 더욱 확대되고 중요해지고 있음이 명백해졌다. 따라서 치과 의사들은 여러 가지 치과수면장애가 개인의 전반적인 건강 과 삶의 질에 심각한 결과를 초래할 수 있다는 점을 염두에 두고 치과수면장애의 해결을 위해서 보다 적극적인 노력을 기울일 필요가 있다고 생각한다. 이를 위해서 치과대학 교 육과정에 치과수면의학을 필수 교과목에 포함시켜야 하고, 치과수면의학에 대한 졸업 후 훈련과정과 치과수면의학 전문가 자격인정제도의 도입이 필요할 것으로 생각한다. 그러나 치과수면의학이 발전하기 위해서는 무엇보다도 치과수면의학에 접근하는 치과의사의 마음가짐이 중요하다고 본다. 즉, 코골이나 폐쇄성 수면무호흡증에 대한 구강 장치요법을 사용하려는 치과의사는 단순히 장치 제작 방법 과 사용법을 익히려고 하지 말고, 수면생리와 수면장애의 전반적인 내용을 이해하고, 수면과 관련된 구강 질병이나 장애를 진단하고 치료하는 의료인으로서의 역할을 더 중요 시 여기는 자세가 필요할 것 같다. 특히 수면은 인간생활의 모든 부분에 영향을 미치고 수면장애는 인체의 거의 모든 영역에 다양한 효과를 나타내기 때문에, 수면문제의 해결을 위해서는 다학제적 접근이 필수적이라고 할 수 있다. 따라서 치과의사로서 수면과 관련된 다른 전문가 그룹과의 협 력과 소통 능력을 갖추는 것도 중요한 일이라고 하겠다."

Korean Janggi and Western plow to have developed for a long time in the east and west were tested and compared in their draft resistance. The charaderistic of Korean Janggi and plow to be able to make deep plowing, on of the most important factors influeneed the increased yield, were ofserved. The study was undertaken to obtain these basic factors' to device and construct the deep plowing Janggi. The results were as follow; 1. The draft resistance of Korean Janggi far less than that of plow and on the dry field, the influence of soil moisture contant to the draft resistance was larger in the Korean Janggi than in the western plow, but on the rice paddy, there was not differences between them. 2. The plow was more stable than that of Janggi in their operation. 3. The relation ship between the specific draft resistance and plowing depth was shown bygthe carved equation. $$K=Ax+\frac{B}{x}+C$$(K ; specific draft restance, x; plowing depth) A, B, C; Constant controled by soil and instrument factor) 4. Minimam values of the specific draft resistance were as follow; a. On the dry field; Korean Janggi; x = $8{\sim}14cm$ $4K=280{\sim}330gr/cm^2$$ Westean plow; x=$10{\sim}12cm$ $$K=480{\sim}490gr/cm^2$$ 6. On the rice paddy; Korean Janggi; x=$8{\sim}12cm$ $$K=255{\sim}280gr/cm^2$ Western plow; x=$7{\sim}10cm$ $$K=415{\sim}420grc/m^2$$
