Background: The purpose of this study was to investigate the effect of taping applied to the lower trapezius on the upper trapezius muscle tone, pain intensity, cervical rotation range of motion in chronic upper trapezius pain patients. Design: Case-control study. Methods: Twenty subjects with chronic upper trapezius pain were classified into an experimental group and a control group. The experimental group applied lower trapezius facilitation taping and the control group applied sham taping. Taping Before and after the application of taping, muscle tone, pain intensity, and cervical rotation range of motion of the upper trapezius were measured. Results: In the experimental group, there were significant differences in the pressure pain threshold and muscle tone before and after taping. In the comparison between groups, there was a significant difference in muscle tone between the experimental group and the control group. Conclusion: The application of the lower trapezius facilitation taping was found to be effective in reducing the pressure threshold and muscle tone of the upper trapezius. Therefore, it is expected that more effective treatment can be provided by adding lower trapezius facilitation taping to the treatment protocol for patients with chronic shoulder pain.

Purpose: The characteristics of oxidized titanium (Ti) surfaces varied according to treatment conditions such as duration time and temperature. Thermal oxidation can change Ti surface characteristics, which affect many cellular responses such as cell adhesion, proliferation, and differentiation. Thus, this study was conducted to evaluate the surface characteristics and cell response of thermally treated Ti surfaces. Methods: The samples were divided into 4 groups. Control: machined smooth titanium (Ti-S) was untreated. Group I: Ti-S was treated in a furnace at 300°C for 30 minutes. Group II: Ti-S was treated at 500°C for 30 minutes. Group III: Ti-S was treated at 750°C for 30 minutes. A scanning electron microscope, atomic force microscope, and X-ray diffraction were used to assess surface characteristics and chemical composition. The water contact angle and surface energy were measured to assess physical properties. Results: The titanium dioxide (TiO2) thickness increased as the treatment temperature increased. Additional peaks belonging to rutile TiO2 were only found in group III. The contact angle in group III was significantly lower than any of the other groups. The surface energy significantly increased as the treatment temperature increased, especially in group III. In the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, after 24 hours of incubation, the assessment of cell viability showed that the optical density of the control had a higher tendency than any other group, but there was no significant difference. However,the alkaline phosphatase activity increased as the temperature increased, especially in group III. Conclusions: Consequently, the surface characteristics and biocompatibility increased as the temperature increased. This indicates that surface modification by thermal treatment could be another useful method for medical and dental implants.

Resin-bonded bridge has been an alternative to conventional bridge, since resin-bonded bridge has many attractive advantages such as minimal tooth preparation, short chair time and low cost over conventional bridge. Unfortunately, however, it was reported that resin-bonded bridge showed high failure rate from debonding of retainer in spite of consecutive advances in preparation and materials. And it was shown that multiple abutments were more likely to fail. The majority of debonding failure was considered due to the mobility of the abutment during function. In this view, recently, modification in resin-bonded bridge design was tried. Single retainer, single pontic. 2-unit cantilevered resin-bonded bridge was applied to clinical performance and was shown as retentive or more retentive than fixed-fixed type resin-bonded bridge. This was consistent with the results of studies in 2-unit cantilevered resin-bonded bridges made with all ceramic, In-ceram. The purpose of this article was to overview principles of design and to analyze clinical results of 2-unit cantilevered resin-bonded bridge in comparison with the reports of fixed-fixed resin-bonded bridge.

Purpose : We evaluated the clinical features of Norovirus gastroenteritis compared with Rotavirus gastroenteritis in hospitalized children. Methods : We detected causative agents in 3,261 samples of children hospitalized with gastroenteritis symptoms at a single center of pediatrics between 2005 and 2006. Among 266 and 303 samples which tested positive for Norovirus and Rotavirus, we selected 73 and 182 samples of children with relatively pure gastroenteritis symptoms and retrospectively analyzed the corresponding medical records. Results : The male-to-female ratio of the Norovirus (+) and Rotavirus (+) groupswas 1.43:1 and 1.56:1 both groups were predominantly in males. The mean age of the Norovirus (+) and Rotavirus (+) groups was 36.7 and 24.4 months, respectively the children in the former group were older than the children in the latter group. The incidence in the Norovirus (+) group was more concentrated in the winter. The symptoms in the Norovirus (+), in decreasing order, included vomiting, diarrhea, and fever. The duration of vomiting, diarrhea, and fever was 2.1, 1.2, and 1.2 days. The maximum number of episodes of vomiting and diarrhea per day was 3.5 and 4.5, respectively. The severity score was 10.16. The symptoms inthe Rotavirus (+) group, in decreasing order, included diarrhea, vomiting, and fever. The duration of diarrhea, vomiting, and fever was 2.2, 4.3, and 2.2 days, respectively. The maximum number of episodes of vomiting and diarrhea per day was 3.3 and 6.5, respectively. The severity score was 11.9. The severity in the Norovirus (+) group was somewhat lower than the Rotavirus (+) group. The younger the child, the more severe the symptoms in the Norovirus (+) group. There was no difference between mono-and co-infection in severity and between the two groups regarding the hematologic findings. Conclusion : Based on the findings reported herein, additional studies about prophylaxis, as well as the epidemiology and clinical features of pediatric Norovirus gastroenteritis, are required. 목 적: 저자들은 입원 중인 환아들을 대상으로 노로바이러 스 장염의 임상 특징을 로타바이러스 장염과 비교하여 조사하였다. 방 법: 2005년부터 2006년까지 한 소아과에 입원 중인, 위장관염 증세를 보여 대변 검사를 시행했던 3,261 검체의 원인체를 검출하였다. 노로바이러스 양성인 266개와 로타바 이러스 양성인 303개의 검체 중, 비교적 순수하게 장염 증세 만 보였던 노로바이러스 감염 73명과 로타바이러스 감염 182 명의 검체를 선별하여 환아들의 임상 기록을 후향적으로 분석 했다. 결 과: 노로바이러스 양성군의 남녀비는 1.43:1, 로타바이 러스 양성군은 1.56:1로 두 군 모두 남아에서 검출률이 높았 다. 평균(중간)연령은 각각 36.7 (22)개월과 24.4 (19)개월로 노로바이러스 양성군의 호발 연령이 더 많았다. 계절적으로 노로바이러스 양성군이 겨울에 국한되어 발생했다. 노로바이 러스 양성군의 임상 증상은 구토, 설사, 발열 순이었고, 평균 구토기간은 2.1일, 설사기간은 1.2일, 발열기간은 1.2일, 하루 최대 구토 횟수는 3.5회, 설사 횟수는 4.5회로 전체적인 Severity score는 10.16점이었으며, 로타바이러스 양성군은 설사, 구토, 발열 순이었고, 평균 설사기간은 4.3일, 구토기간 은 2.2일, 발열기간은 2.2일, 하루 최대 설사 횟수는 6.5회, 하루 최대 구토 횟수는 3.3회로 전체적인 Severity score는 11.9으로 나타나 노로바이러스 양성군이 증상의 중증도가 다 소 낮았다. 노로바이러스 양성군은 어릴수록 증상의 중증도가 심하게 나타났으나, 로타바이러스 양성군은 연령에 따른 중증 도의 차이를 보이지 않았다. 단독감염과 혼합감염의 중증도는 차이를 보이지 않았다. 혈액 검사 상 두 군 간에 유의한 차이는 없었다. 결 론: 소아 노로바이러스 장염의 역학, 임상 증상 뿐만 아니라 예방에 대한 더 많은 연구가 필요하다.

Dental implantation is a method restoring missing teeth, especially in the case of severely resorbed edentulous patient. But the direct contact between bone and implant surface, induces stress concentration to the bone and eventually becomes a cause. The purpose of this study was to compare the stress distribution patterns between following two cylindrical implant models. One group has implant apex located in the inferior cortical bone and the other in the cancellous bone. Anterior edentulous mandible was modeled with two dimensional 953,878 nodes, 995,918 elements and compared the deflection and stress distribution under the 70 N,4 load cases for 26 models having variant mandibular height and length. The result were as follows; 1. The stress concentration was more affected by the height of the mandible than implant length. 2. Bicortication mitigates the stress of upper cortical and cancellous bone area at the same height of the mandible 3. Perforation of the inferior mandibular cortex significant stress concentration. 4. Stud type porstheses induced less stress concentration to the cortical and cancellous bone than bar type prostheses. 5. Stress of implant apex for stud type was larger than that of bar type.

Ceromers, new indirect resin system, are now being adopted for esthetic restorations. Despite of its translucency and good color matching, color stability after long-term use was unknown till now. This in vitro study was designed to evaluate color stability of some ceromers when subjected to brushing after thermocycling. Three types of ceromers: Scupture, Targis, Artglass and a direct resin system, Z100 were prepared to disks 12 mm in diameter, 2.5 mm in thickness. All specimens were polished, and Sculpture and Targis specimens were divided two groups, respectively. Then, half of them were glazed according to manufacturer's instructions. All specimen were brushed 20,000 times after 10,000 cycle thermocycling. Color was measured with spectrophotometer after 1,000, 3,000, 10,000 times thermocycling and 20,000 time brushing, respectively. Color difference (${\Delta}E$) was calculated according to CIE LAB system. During thermocycling, Sculpture & Targis system with polished surface showed greater color change than any other groups. After brushing, color difference was reduced significantly. Mean values of ${\Delta}E$ ranged 0.98 to 2.98. All Ceromers were considered clinically acceptable after thermocycling and brushing, and color change mechanism was affected by the brands and finishing methods. It might be concluded that color change of ceromer is due to surface alteration.
