Objectives : The purpose of this study was to examine the oral health knowledge, attitude, behavior among 918 secondary students and their needs for oral health education in Seoul, Gyeonggi Province and Choongbuk Province. Methods : The collected data were analyzed by the statistical package SPSS 18.0, and frequency analysis, correlation analysis, crosstabs, t-test and ANOVA were utilized. Results : The girls proceeded the boys in oral health knowledge, and the high school students were ahead of the middle schoolers in oral health knowledge, attitude and behavior. Those who ever received oral health education surpassed the others who didn't in oral health knowledge and behavior(p<0.01). The students hoped to be provided with oral health education by dental hygienists during regular classroom hours once per semester, 30 minutes to one hour at a once, and their favorite ways of oral health education were videotape watching and practice. As for needs for oral health education, the middle school students had higher needs for that than the high schoolers, and the former's needs scores were above the average(p<0.05). Conclusions : There were differences among the students in oral health knowledge, attitude and behavior according to their school system, gender and oral health education experiences, but oral health education was provided without taking their differences into account. It was recommended, efficient oral health education programs should be developed by focusing on how to take care of and prevent oral diseases, and videotape watching and practice that were preferred by the secondary students should be included in the programs.

구치부 교합지지가 상실되면 수직교합고경이 감소되면서 대합치의 점진적인 정출과 전치부 치아들의 전방 돌출을 초래하게 되고 결국 교합평면이 붕괴됨과 아울러 안모의 변화, 저작 효율 저하, 그리고 측두하악관절 장애 등의 문제가 발생할 수 있다. 이 경우, 정확한 진단 과 예지성 있는 치료계획 수립을 통한 교합평면 재설정 및 수직고경 회복이 필요하다. 본 증례는 71세 여성 환자로, 교합 평면이 붕괴되고 구치부 보철 수복 공간이 부족하여, 수직고경 거상을 동반한 완전구강회복을 계획하였다. 생리적 하악안정위, 연하, 발음, 안모, 전치부 평균 길이 등을 평가하는 임상적 과정을 통해 적절한 수직고경 및 3차원적 교합평면을 재설정하여 임시보철물을 제작하였고, 약 5개월 간 임시 보철물 상태로 악관절 및 저작근의 적응 여부를 관찰하고 교합을 안정화하였다. 기능적, 심미적 임상증상이 없음을 확인한 후 최종 보철 수복하였다. 이러한 환자친화적 완전구강회복 과정을 수행하여 기능 및 심미적으로 만족스러운 결과를 얻었기에 이를 보고하고자 한다.

본 연구는 악교정 환자 중 9명의 골격성 3급 부정교합 환자를 대상으로 음향학적 분석을 통하여 술전, 술후에 나타나는 발음상의 차이를 살펴보았다. 술전, 술후간 모음 조음상의 차이는 술후 혀의 후방, 하방 이동과 동시에 목젖의 후상방 이동으로 인한 구강 내 조음 공간의 극대화로 요약할 수 있다. Long-term average 스펙트라 분석 결과, /ㅅ/의 조음상의 차이는 술전에서는 마찰소음 에너지가 전 주파수대에 걸쳐 고른 분포를 보이나 술후에는 정상인과 같이 고주파수대에 집중되는 경향을 보였다. 동시에 마찰소음의 peak frequency는 술후에서가 술전에 비해 높게 나타났다.

In order to evaluate the influences of Myo-monitoring on masticatory muscles, Myo-monitoring on 31 normal persons and 30 persons with one more temporomandibular dysfunction symptoms during 45 minutes or above. The author observed velocities of mandibular opening and closing movement, variabilities of mandibular rest position and EMG activities of temporal and masseter muscles. The obtained results were as follows : 1. There were no significant differences on velocities of mandibular opening and closing movement between before and after Myo-monitoring. 2. There were significant differences on vertical dimension and total dimension form mandibular rest position to centric occlusion between before and after Myo-monitoring but no significant differences on anteroposterior and lateral dimension. 3. Activities of temporal and masseter muscles were decreased in Myo-Monitoring. 4. There were disappeared significant differences on EMG activity values between normal and symptom groups after myo-monitoring.

악관절 잡음과 동통,과두 흡수를 동반한 퇴행성 측두하악장애는 교합 불안정과 개구장애 를 동반하기도 한다. 진단을 위해 CT나 MRI를 이용해 과두 형태 및 디스크 위치를 파악하 는 것이 유용한 접근법이다. 퇴행성 측두하악관절 환자는 CT나 MRI를 이용하여 진단하고, 과두-원판 재위치와 근 기능 개선을 위해 장기간 교합 안정장치 사용이 필요하므로 교정치료 기간에 변형된 교합 안정장치의 병용이 필요하다. 이에 본 연구에서 교합 안정장치를 병용하여 교합 재구성 증례를 CT나 MRI로 고찰해 보고자 한다.

Objectives : The aim of this study was conducted that CRE (Coptidis Rhizoma Extract) induces apoptosis in YD-10B cells, human oral squamous carcinoma cell line. Methods : In this study, YD-10B cells were exposed to CRE (0.03-0.30 mg/ml), for 6-24 hours. We measured the effects of CRE on the changes of cell viability and cell membrane, TUNEL assay of CRE-treated YD-10B cell. Results : In this study, CRE caused a decrease of viability in YD-10B cells, human oral squamous carcinoma cell line. When YD-10B cells were treated with CRE, cells showed dose-dependent manner apoptotic cell death. Conclusions : These results suggest that CRE may be potential therapeutic approach in the clinical management of oral squamous cell carcinoma.

In order to study of muscle fiber proportion of masticatory muscle, 6 rabbits masticatory muscles (masseter, temporal, internal pterygoid, external pterygoid) were excised. Muscle specimens were fixed in 10% neutral buffered formalin fixer and sectioned $5{\mu}$ for PAS staining. With the light microscopic photograph the proportion of muscle fibers of each muscle were computed. The results were as follow; 1. Average classical red fiber proportion of rabbit masticatory muscles was 85.7% 2. Masseter muscle revealed 90.3% of classical red fiber in the rabbit masticatory muscles.

Myoepithelioma is histologically composed exclusively of myoepithelial cells. Myoepithelial cells are present in the major and minor salivary glands. Salivary gland neoplasms that frequently contain myoepithelial cells are the pleomorphic adenoma, adenoid-cystic carcinoma, and epithelial myoepithelial carcinoma of intercalated duct origin. Neoplasms composed exclusively of myoepithelial cells are rare. Myoepitheliomas may be composed of spindle-shaped cells, plasmacytoid(hyaline) cells, or combination of both in varying proportions. A case is reported of plasmacytoid myoepithelioma with ultrastructural confirmation, together with reviews of the English literature.

The authors have observed clinically and histopathologically on two cases of rhabdomyosarcomas occurred in the oral cavity. The results were as follow: 1. A case of adult pleomorphic rhabdomyosarcoma, involving the right mandibular third molar area of 52 year old male, revealed pathological fracture of the right mandibular angle area. Microscopically, sections of this tumor showed cross striations by staining of phosphotungstic acid hematoxylin. 2. A case of embryonal alveolar rhabdomyosarcoma, involving the right buccal area of one year and ten months old female, revealed severe bone destruction on the right mandibular body area. Microscopically, sections of this tumor did not show cross striations.

다른 근골격성 질환에서와 같이, 측두하악장애의 징후와 증상은 일시적이거나 자기 한정적(self-limiting)인 경우가 많다. 따라서 복잡한 교합 치료나 수술과 같은 비보존적, 비가역적 치료를 초기치료로 선택하는 것은 가급적 피해야 한다. 또한 자가요법, 행동 수정, 물리치료, 약물요법, 장치치료 등과 같은 보존적, 가역적 치료가 측두하악장애의 초기치료로 추천된다.
