This study was performed to identify the relationship between scaling behaviors and knowledge about scaling and oral health belief of worker, and to provide baseline data for developing industry oral health policy. The survey had conducted self-administered questionnaires by 326 workers in Gyeongsan and Yeongcheon areas in Gyeongbuk province. Their scaling behaviors, knowledge and oral health belief were measured. The results were as follow; The average score of knowledge about scaling was 6.44. The average oral health belief was 2.72. In detail, 'usefulness' was 3.24 as the highest and 'seriousness' was 2.25 as the lowest. The periodic scaling and scaling cycle were associated with 'seriousness' and 'barrier' as positive correlation(p<.05, .01). On the other hand, they were associated with knowledge and 'usefulness' as negative correlation(p<.01). Meanwhile, scaling motive showed positive correlation with 'cue of action'(p<.01), showed negative correlation with knowledge(p<.01). In the correlation between knowledge about scaling and oral health belief, knowledge showed negative correlation with 'barrier'(p<.01) and showed positive correlation with 'usefulness'(p<.01). Finally, we need to advertise and manage the importance of scaling politically and makes people do the voluntary scaling in six-month intervals in order to keep the periodontal health of worker.

Various nerves from many areas of body can be used as a donor of autogenous nerve graft in the microneurosurgical repair of the oral and maxillofacial region. In the grafting procedure of nerve repair, the best results will be achieved with a maximum approximation of fascicular surface at both the porximal and the distal stumps. Therefore, appropriate selection of donor nerve will bring out the best results. The sural nerve has been used as one of the most popular donor nerve in the microneurosurgical repair of the oral and maxillofacial region. The authors examined the fascicular characteristics of the human sural nerve microscopically and compare this results with our previous report of the greater auricular nerve and that of the inferior alveolar nerve.

We have to consider two parts of the evaluation and treatment for the patients with head and neck burns. The primary consideration is swallowing function for nutrition supply for them and the next is speech function for efficient communication and aesthetic impression of them. The purpose of this study is to summarize the preliminary questions of Communication Screening Protocols which can help understand comprehensively on swallowing disorder, motor speech disorder and voice disorder of patients with head and neck burns. We divided the evaluation into 4 evaluation areas including 'oral mechanism', 'respiration/voice', 'articulation', and 'swallowing' by referring to overseas studies dealing with various communication disorders caused by burns, and prepared the final questionnaires by conducting the content validity verification by five expert (speech & language pathologist). The range of Content Validity Index was shown relatively appropriate with .50~.84. There was a conflict of opinions in experts whether the items in the areas of respiration/voice and swallowing may be appropriate, whereas there was no different view of the oral mechanism and articulation area. Through the different characteristics of communication difficulties of patients with head and neck burns, we expect it will be modified appropriately according to the patients through evaluation of burn patients by type and severity.

스트레스가 질병 및 동통과 밀접하게 관련되어 있다는 것은 주지의 사실이며, 정서적으로 중요한 구강안면영역에는 측두하악관절장애증, 구강작열감증후군 등의 다양한 스트레스성 질환이 존재하는데, 이들의 병리학적 기전에 대해서는 아직도 논란의 여지가 있다. 그리고 중추신경계인 뇌는 스트레스 반응 및 동통 신호의 전달과 조절 등에서 중요한 역할을 하는 부분이다. 이에 저자는 스트레스와 신경과의 병리적관계를 조직학적으로 밝히고자 구속스트레스하의 백서 뇌조직을 채취하여 전자현미경으로 세포변화를 관찰하였다. 생후 8주된 Sprague-Dawley계 웅성 백서 (322-367 g/bw)를 대조군으로 3마리, 실험군으로 15마리를 배정하였다. 실험군은 구속스트레스를 실험 전기간에 걸쳐 부여하였다. 모든 실험동물의 뇌간을 적출하여, 전자현미경으로 조직변화를 관찰하였으며, 그 결과는 다음과 같다. 1. 정상 대조군에서는 정상적인 형태의 수상돌기 및 세포체가 관찰되었다. 2. 구속스트레스군의 5일군과 7일군에서 작은 크기의 사립체가 다수 출현하였다. 3. 구속스트레스 3일군부터 핵주위의 공포화(vacuolization)로 핵과 세포질이 이개되었으며, 7일군에서는 이러한 핵주위의 변성이 현저하였다. 구속스트레스 부여 후 뇌세포의 미세구조를 관찰한 결과, 세포내 미세구조 및 세포간극의 변화가 있었던 것은 스트레스에 의해 신경세포가 변성될 수 있다는 것을 의미하는 것으로, 이는 스트레스와 관련된 구강안면동통 등의 질병 기전을 밝히는데 도움이 되리라 사료되며, 향후 이에 대한 추가적인 조직학적, 분자생물학적인 연구가 필요하리라 생각된다.

Alagille syndrome is an autosomal dominant genetic disorder and occurs in approximately 1 in 100,000 live births. Diagnostic criteria was established by Alagille. It is mainly caused by a mutation in the Jagged1 gene. Major clinical features of this syndrome are paucity of intrahepatic bile duct with cholestasis, characteristic facies, cardiac murmur, defects of vertebrae, and embryotoxon. And minor clinical features are mental retardation, renal involvement, growth retardation, other skeletal abnormalities, a high-pitched voice. The surviving prognosis of Alagille syndrome patients depends on the severity of cardiovescular malformation in the early ages of infant. However, with the increasing years, it depends on the severity of the liver disease. Cholestasis causes congenital jaundice, malnutrition and growth retardation. Also, the increase of serum cholesterol level cause xanthoma and pruritus. Even though the severity of these problems are reduce with age, there is cases where there is no way but liver transplantation. For oral features of Alagille syndrome patients, green discoloration of entire dentition, induced by bilirubin infiltration into dentinal tubules, is especially. Also, xanthoma on gingiva and partial hypodontia have been reported. This report is on the oral features of an Alagille syndrome patient who visited to Kyung-Pook University Hospital.

치의학 분야에서 디지탈 근적외선 체열측정 장치(digital infrared thermographic imaging; DITI)의 응용이 미미한 것은 과거 열측정장치의 기술력이 부족한 것이 주된 요인이었다. 그러나 최근들어 기술이 진보함에 따라 실시간 열영상을 재현할 수 있게 되었고 이는 치의학 및 의학계에 많은 관심을 일으키고 있다. 지금까지의 연구를 보면 두개하악장애시 구강영역의 온도변화의 임상적 효용 가능성을 제시하였으나 안면 및 두경부에 대한 실제 기기 및 측정방법의 신뢰도에 대한 연구는 이루어지지 못한 상태이다. 본 연구에서는 DITI에 대한 신뢰도를 조사하였다. DITI의 모니터 상에서 비활동성 발통점의 부위를 찾아내기가 쉽지 않다. 따라서 모니터상에서 안면발통점(joint, temporalis anterior, masseter anterior, masseter inferior)의 부위를 찾아 온도를 찾아내는 방법과 미리 발통점 피부상에 링모양의 마크를 부착하여 모니터상에서 쉽게 찾아내는 방법을 사용하여 신뢰도를 조사하여 비교한 결과 다음과 같다. 1. 조사한 발통점 중에서 temporalis anterior, joint, masseter anterior과 masseter inferior의 순서로 피부온도가 유의하게 온도가 높았으나(p<0.05) masseter 내에서는 유의한 차이를 보여주지 않았다. 2. 4개의 발통점 모두에서 높은 열적 대칭성을 보였으며, 좌우 온도차이는 $0.1^{\circ}C$미만이었다. 3. 다른 시기에 조사한 조사자내 신뢰도는 두 조사자 모두 높은 상관관계를 보여주지 않았으며 대조군과 마크를 사용한 군간에는 뚜렷한 차이를 볼 수 없었다. 4. 동일한 시기에 조사한 조사자간 신뢰도는 두 시기 모두 joint 부위의 일부를 제외하고 높은 상관관계를 보여주었으며, 마크를 사용한 경우 사용하지 않은 경우 보다 훨씬 신뢰도가 높은 상관관계를 나타내었다. 이상의 결과로 보아 DITI는 두개하악장애환자에 대한 두경부 발통점의 온도변화를 측정하는 데 있어 시간에 따른 신뢰도는 결여되었으나 동일 시기의 측정에는 매우 유익할 것으로 사료되며, 특히 발통점에 대한 표시를 사용하는 경우 매우 정확한 온도를 조사할 수 있을 것으로 판단된다.

The purpose of this study was to examine the health segment of the 7th national physical education curriculum in an effort to grasp the state of oral health education in the school curriculum. And it's also meant to investigate the relationship between oral health education and the oral health awareness of some high schoolers to check into any possible problems with oral health education as part of health education. The subjects in this study were 240 students from two different girls' high schools in Seoul, on whom a survey was conducted to find out their oral health knowledge, behavior and awareness. And the health category of the current P.E. curriculum announced by the Ministry of Education was analyzed. The findings of the study were as follows: Oral health education provided by the high schools as part of health education in P.E. class wasn't linked to P.E. theories and practice. The weight of oral health education was extremely small in the health segment, and there was no sequence, continuity and integration among the content systems of oral health education for different grades. When some high schoolers were investigated, they weren't properly oral health conscious, though it was very important for students to receive oral health education to prevent and manage dental diseases. And they didn't consequently take care of their own oral health. Future research efforts should be channeled from diverse angles into developing oral health education curriculums to bolster school oral health education to improve national oral health.

This study is a convergence study attempted to understand the learning effects of oral health education class applying action learning on the communication ability and problem-solving ability in dental hygiene students. The subjects of this study were 37 students in the third year of dental hygiene department. As a result, the learning effects of oral health education class applying action learning on the communication ability(p<0.001) and problem-solving ability(p<0.001) showed positive changes in the pre and post comparison. The changes in the scores of sub-dimensions of the communication ability and problem-solving ability were also significant in the pre and post comparison. As the class applying action learning is effective in improving the learner's communication ability and problem-solving ability, it should be utilized as the leaner participation-oriented teaching method for design and operation of dental hygiene education.

Behcet's disease(BD) is a multisystem vasculitis that almost any organ in the body may be involved. Its diagnosis bases on clinical criteria in the absence of any specific laboratory test to confirm it. The clinical criteria proposed for the diagnosis for BD include recurrent oral and genital ulceration, skin lesion, ocular changes, and positive response to pathergy test. Besides these essential features, BD may manifest itself on the gastrointestinal tract, central nervous system, and other systemic involvements. Among these clinical features, recurrent oral ulcers are present in most BD patients, often as the initial symptom, preceding other manifestations by many years. Therefore, dentists are in the important position for the early detection and diagnosis of BD. In this case report, we are presenting a case of 6 year-old girl, who came to the pediatric dentistry department for evaluation and treatment of pain and dysphagia caused by severe recurrent oral ulcers. Through taking detailed dental and medical history and clinical examination, we reported the possibility of BD to the medical team and prescribed topical lidocaine to relief pain during swallowing. The medical team, which involved pediatrics, ophthalmology, dermatology, and gastroenterology, finally confirmed BD through various examinations. Detection of the possibility of BD in the dental field helped early diagnosis and proper management by the medical team.

Recently, bisphosphonate-associated osteonecrosis of the jaw(BONJ) is added to the list of diseases of the oromaxillofacial region. BONJ is defined as exposed bone in the jaw that does not heal within 8 weeks after identification, in a patient who has been received to bisphosphonates and has not taken radiation therapy to the craniofacial region. Bisphosphonates binded to bone mineral are concentrated in highly active remodeling site, reside in the skeleton for a long time, and do a role as powerful inhibitors of bone resorption. As the patients receiving bisphosphonates therapy grow in number, the patients of BONJ would go on increasing in Korea. We would like to present two patients who were suspected to BONJ, describe the outline of BONJ, and mention importance of our understanding about BONJ. BONJ is rare disease, but once it develops, its prognosis is very poor. Our adequate understanding of BONJ is necessary to prevent it and cope with it properly.
