PURPOSE: This study examined the effects on the upper extremity function, muscle strength, and hand function of a task-oriented training approach using a percussion instrument for patients with chronic stroke. METHODS: Twenty-four chronic stroke patients accompanied with upper extremity hemiplegia were selected for research and were classified randomly into 12 experimental groups and 12 control groups. The experimental group performed a task-oriented approach, and the control group performed upper extremity occupational therapy. Stroke upper extremity test, Jebsen-Taylor Hand Function test, upper extremity muscle strength test, and hand muscle strength test were measured before and after training in the evaluation process. RESULTS: In the upper extremity test and Jebsen-Taylor test, there were no significant differences between the groups. In the upper extremity muscle strength test, there were significant differences in shoulder flexion, internal rotation, and elbow flexion in the experimental group. In the hand muscle strength test, there were significant differences in the grip, tip Pinch, lateral Pinch, and 3-jaw chuck in the experimental group and significant differences in only grip, tip pinch, and lateral pinch in the control group. In addition, there were significant differences in the lateral pinch compared to the amount of change. CONCLUSION: Task-oriented approach using percussion instruments for upper extremity rehabilitation in stroke patients is effective in the upper extremity function and strength, hand function, and strength.

목적: 일반적으로 총의치는 환자의 구내에서 제거 시 물에 담가 보관하도록 설명하는데, 수중에서의 총의치의 보관이 상온의 공기중에서 총의치를 보관하는 것과 비교해 체적 안정성에 장점이 있는지에 대한 연구는 부족하다. 본 연구는 의치의 올바른 보관 방법을 규정하는 데에 참고가 될 수 있도록, 수중에서 보관하는 경우와 공기중에 보관하는 경우에 의치상의체적 변화량과 양상을 평가하는 것을 목적으로 한다. 재료 및 방법: 초경석고로 제작한 주모형을 디지털 스캔하여, computer-aided design (CAD) 소프트웨어를 이용해 총의치 의치상을 디자인하고, 3D printing 기법을 이용하여 상악과 하악 각 6개의 시편을 제작하였다. 이를 매몰한 후 열중합 방식으로 온성하여 제작한 레진의치상을 상악과 하악 각 3개씩 그룹 A와 그룹 B로 나누었다. 그룹 A는 상온의 공기중에서 보관되었고, 그룹 B는 상온의 물에 담가 보관하며 24시간 간격으로 28일 동안 스캔하여 stereolithogrphy (SLA) 파일로 저장하였다. 이를 분석하여 한달 간의 체적변화를 측정하였고, best-fit 알고리즘을 이용하여 중첩시켜 3차원 비교 컬러맵을 이용하여 의치상 인상면의 변화 양상을 관찰하였다. 측정한 값은 Kruskal-Wallis test를 이용하여 분석하였다. 결과: 보관방법에 상관없이 총 체적에는 유의한 변화가 없었으나, 공기 중에서 보관한 의치상의 경우 상악 구개부와 하악 구치부 설측 변연에서 조직과 멀어지는 방향으로, 상악 결절부와 하악 후구치 삼각 융기 부위에서는 조직을 압박하는 방향으로 통계적으로 유의한 변화를 보였다. 결론: 수중에서의 의치 보관은 공기중에서의 의치 보관에 비해 의치상 인상면의 변화가 적게 나타났다.

The patient, 21 years and 3 months female, complained of protrusion of lower face. There was severe procumbency of upper & lower anterior teeth. Cephalometric analysis revealed that the anteroposterior jaw relationship was normal, but the teeth was foreward on their respective basal bones, so diagnosed as bimaxillary dental prognathism. The patient underwent extraction of four Ist premolar and was treated with multibanded & direct bonding system. After 14 months, She gained good interdigitation of buccal segment and attractive facial profile.

Twenty three year old soldier, was referred to me because of extreme mandibular prognathism. Eight years before, the patient had become aware of some protrusion of his mandible. Up until this time, his jaws seemed to have been developing normally. The oblique osteotomy of the mandible was performed. Risdon cable wiring was used in the upper and lower jaw in order to immobilize the mandible by intermaxillary wiring. The patient recovered from the operation, and was discharged from the 1st Army Hospital after 6 months with good functional mandibular relationship. The appearance of the patient was greatly improved.

The pain was induced on upper and lower incisor of the rat based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'. Such acupoints as ST36 and LI4 were used for alleviation of upper and lower incisor pain. The digastric myogram (dEMG) was utilized for the pain measurement. The upper incisor pain was gradually decreased during ST36 stimulation and significant differences were observed at 20 and 25 minute point during 60 minutes study. The upper incisor pain was gradually decreased during LI4 acupuncture and 20 minute was the only point that showed a significant difference. The alleviation of lower incisor pain was not obvious during the ST36 acupuncture. The lower incisor pain was gradually decreased during LI4 stimulation with significant differences at 15, 20 and 40 minute point. In conclusion, the upper incisor pain was relieved with ST36 and LI4 acupuncture while LI4 was effective on the lower incisor pain alleviation based on the theory of 'connections of upper incisor pain with stomach meridian and lower incisor pain with large intestine meridian'.

Stellate ganglion block is extensively performed in pain closing to treat a diversity of diseases. Stellate ganglion phenol neurolysis, however, has not been not popular because of risk and complications such as: permanent horner's syndrome, hoarseness, pneumothorax and intravascular or intraspinal injection. But Racz recently performed stellate ganglion phenol neurolysis successfully, under fluoroscopic guide, minus significant complication. Three patients were recently treated at our pain clinic by repeated stellate ganglion block with local anesthetics. Patients showed immediate signs of improvement but prolonged pain relief was not achieved. Therefore we reported to performing stellate ganglion phenol neurolysis following Racz's technique. We successfully treated: two cases of reflex sympathetic dystrophy of the upper extremity, and a case of postherpetic neuralgia of jaw, neck and upper chest wall, by stellate ganglion phenol neurolysis, devoid of any significant complications.

The diagnostic value of a intra oral film is related to projecting technic and interpretation. The intra-oral film is a single plane representation of a three dimensional object, therefore superimposition is inevitablly present. The purpose of this article is to show how foreign objects in the jaw may be localized. The author used double exposure technics, that are changed angulation of vertical or horizontal to one film. The obtained results are as fallow: 1. In the upper anterior region, the moving distance of the labially impacted reference object was greater than that of the palatally impacted one. 2. In the upper molar region, the moving distance of the mesiobuccal root apex was the greatest and that of palatal root apex was the shortest. 3. In the lower molar region, the change of the alveolar bone level in the buccal side was greater than that of lingual side.

치면열구전색술이 건강보험급여 항목에 포함된 이후 진료경향을 분석하여 치아우식예방을 파악하고자 2009년 12월 1일부터 2014년 12월 31일까지 건강보험심사평가원 대전지원에 접수된 요양급여비용 명세서를 분석하였다. 연도별 치면열구전색술 현황을 살펴보면, 2010년에 수진자 수와 수진자 처치 치아수가 가장 많았고, 1인당 평균 처치 치아수는 2013년에 3.39개로 가장 높게 나타났다. 일반적 특성에 따른 2010년 제1대구치 치면열구전색술을 분석한 결과 남자가 여자보다 높았고, 연령별에서는 7세에서 가장 높게 나타났고 계절별로는 여름이 가장 높았다. 각 제1대구치 분포에서는 상악좌측 제1대구치가 가장 높았으며 그 외는 상악우측 제1대구치, 하악우측 제1대구치, 하악좌측 제1대구치 순으로 나타났다. 2010년에 상악 우측 제1대구치에 치면열구전색술한 후 치아우식이 발생되어 2011년부터 2014년에 충전을 시행한 치아를 분석한 결과, 남자가 여자보다 높게 나타났고, 연령별에서는 7세에서 가장 많은 충전을 실시하였으며, 계절별로는 여름에 가장 많이 실시한 것으로 나타났다. 2009년 12월부터 2014년 11월까지의 치료 치아수를 토대로 2015년 12월까지 치아 치료수를 예측한 결과 2015년도 8월에 가장 높은 수요가 나타날 것으로 예측되고 2014년에 비해 감소될 것으로 예측된다. 따라서, 칫솔질만으로는 치아우식증 예방에 한계가 있으므로 높은 예방효과를 보이는 치면열구전색술 실시를 영유아 및 초,중,고 구강보건실등에서 정기적인 실시한다면 치아우식 예방효과가 있을것으로 기대된다.

To prevent musculoskeletal disorders(MSD) for dental hygiene students, who will potentially be at high risk of developing MSD while performing oral prophylaxis practice, an MSD prevention education program was designed and was offered to a group of dental hygiene students to find whether the program is effective. Before the program started and three months after the program ended, changes in the students' posture were filmed to observe them. The final subjects for analysis included 30 students in the experimental group and 41 students in the control group. To verify differences between the experimental and the control groups, repeated measures ANOVA was carried out before and after the program. After the education program, the experimental group's RULA scores for neck, left upper arm, right forearm, and wrist, RULA A score on both left and right side, RULA B score on left side, and total RULA score were significantly lowered during the operation on the upper jaw, compared with that of the control group. And, during the operation on the lower jaw, the experimental group's RULA A score, RULA B score, and total RULA score were very significantly lowered. The results of this study suggest the MSD prevention education program is effective in preventing the disorder. Thus, the program can be utilized as an education program for preventing MSDs during dental hygiene students' oral prophylaxis practice and clinical practice.
