OBJECTIVES: To discern in advanced uterine cervical cancer whether the hyperfractionation is more effective in tumor control and in reducing radiation complication rates than the simple fractionation. METHODS: We retrospectively reviewed the medical records of 184 patients with advanced cervical cancer at our hospitals from January 2000 to December 2004. All patients were treated with radiation, 114 patients with simple fractionation, and 70 patients with hyperfractionation. RESULTS: Mean age was 55.4 years at baseline study. Complications were occurred in 90 patients of the 184 patients who treated with radiation therapy. Of these, 48 patients suffered from gastrointestinal complications, 24 patients suffered from genitourinary complications and 18 patients had both complications. Complications were occurred in 72 cases in simple fractionation group and 40 cases in hyperfractionation group. 77 patients had acute complications and 13 patients had chronic complications. There was no statistically significant difference between two groups (P = 0.772). Mild complication were occurred in 75 patients and severe complication were occurred in 15 patients, there was no statistically significant difference in two groups (P = 0.495). 66 patients had gastrointestinal complications and 42 patients had genitourinary complications, there was no statistical significance in two groups (P = 0.910). CONCLUSION: Many complications were occurred in patients who treated with radiation therapy, but there was no statistically significant survival and complication difference in two groups. Further research is needed.

성지영,강경화 대한치과교정학회 2009 대한치과교정학회지 Vol.39 No.4

본 연구의 목적은 세라믹 브라켓 제거 후 재접착 시에 브라켓의 종류, 브라켓의 제거 방법, 브라켓 베이스의 처리방법에 따른 전단 결합 강도를 평가하여 임상에서 적절한 전단 결합 강도를 얻을 수 있는 세라믹 브라켓의 재접착방법을 찾고자 하는 것이었다. 총 312개의 치아로, 144개는 재접착을 위한 브라켓을 만들기 위해 이용되었고, 나머지 168개는 재생 브라켓의 베이스 처리 후 접착을 위해 사용되었다. 브라켓의 종류(단결정 세라믹 브라켓, 다결정 세라믹 브라켓), 브라켓의 제거 방법(만능 시험기를 이용한 전단력에 의한 제거, 레이저에 의한 제거), 브라켓 베이스의 처리 방법(저속 라운드 버로 선택적 삭제, 샌드블라스팅 처리, 샌드블라스팅 후 실란 처리)에 따라 12개의 실험군과 2개의 대조군(단결정, 다결정 새 브라켓)으로 분류하여 각 군당 12개의 치아를 할당하였다. 각 실험군의 조건에 따라 브라켓을 재접착한 후에 전단 결합 강도와 접착제 잔류 지수를 평가하고 베이스 처리 방법에 따른 브라켓 베이스의 변화를 관찰하였다. 연구 결과, 단결정 세라믹 브라켓군은 샌드블라스팅 처리하고 재접착한 군에서만 다결정 세라믹 브라켓군보다 전단 결합 강도가 유의하게 높았다 (p < 0.05). 전단력으로 브라켓을 제거하고 재접착한 군과 레이저로 브라켓을 제거하고 재접착한 군 간에 전단 결합 강도는 유의한 차이가 없었다. 브라켓 종류와 제거 방법에 관계없이 샌드블라스팅 후 실란 처리하고 재접착한 군은 저속 라운드 버로 선택적 삭제하고 재접착한 군과 샌드블라스팅 처리하고 재접착한 군보다 전단 결합 강도가 유의하게 높았다 (p < 0.001). 베이스 형태는 전단력으로 제거한 군보다 레이저로 제거한 군에서 더 잘 유지되었으며, 재접착을 위해 베이스 처리된 모든 브라켓에서 새 브라켓보다 부드러운 표면을 나타내었다. 이상의 결과를 토대로, 제거된 세라믹 브라켓에 샌드블라스팅 후 실란을 처리하고 재접착는 것이 전단 결합 강도를 증가시켰으며, 저속 라운드 버를 이용한 선택적 삭제나 샌드블라스팅만 처리하여 재접착하는 방법도 임상적으로 수용 가능한 결합 강도를 보였다고 할 수 있다. Objective: The purpose of this study was to evaluate the shear bond strength of rebonded ceramic brackets according to each condition and find an appropriate method to rebond ceramic brackets with proper shear bond strength in clinical practice. Methods: The study consisted of 12 experimental groups, according to the types of brackets, debonding methods, and treatment methods of the bracket base. Shear bond strength was measured, and adhesive residues left on the tooth surface were assessed. The base of the bracket was examined under scanning electron microscopy. Results: The shear bond strength of the monocrystalline ceramic bracket group was significantly higher than thatof the polycrystalline bracket group with only sandblasting (p < 0.05). There was no significant difference in shear bond strength between groups that used rebonded brackets which were debonded with shear force and debonded with laser (p > 0.05). The shear bond strength of the sandblasted/ silane group was significantly higher than that of the selectively grinded group with a low-speed round bur and the sandblasted only group (p < 0.001). The retentive structure was more presented in groups where laser was applied than in groups where shear force was applied to debond brackets prior to rebonding. The bracket bases which were treated before rebonding presented smoother surfaces than new brackets. Conclusions: Shear bond strength could be increased by applying a silane coupling agent after sandblasting before rebonding. Also, the bond strength of the selectively grinded group with a low-speed round bur and the sandblasted group showed acceptable bond strength for clinical orthodontic treatment.

The crown-root fracture is defined as a fracture of tooth that contains enamel, dentin and cementum with or without pulp exposure. Generally the fracture lines place obliquely from labial surface, between incisal edge of the crown and marginal gingiva, to palatal surface subgingivally. If the fracture line is located supragingivally, the removal of tooth fragment and supragingival restoration can be performed. In subgingival fracture line, the surgical exposure, orthodontic eruption or surgical eruption can be considered. If the fracture line is too deep to restorate, extraction or decoronation can be selected. In children and adolescents, the extraction should be the last option. Another option to select before extraction is the restoration using fiber-reinforced post and the reattachment of tooth fragment. The fiber-rainforced post enhances the retention and the durability of tooth fragment. The reattachment of crown fragment using resin adhesive system is considered minimal invasive treatment biologically. This case reports the treatment of crown-root fracture using the reattachment of crown fragment and the insertion of fiber-reinforced post. 치관-치근 파절은 법랑질, 상아질, 백악질이 모두 포함된 치아의 파절로, 파절선이 대부분 절단연이나 순측의 변연부 치은 에서 구개측 치은열구 하방으로 사선으로 진행된다. 파절선의 위치가 치은 연상이라면 파절편의 제거 및 치은연상 수복을 시 행하고, 치은 연하라면 파절면의 외과적 노출술, 교정적 정출술, 외과적 정출술을 이용한 치아의 수복이 이루어진다. 그 외에 섬유 강화형 포스트를 삽입하여 치관 수복물의 유지력을 높이고, 레진 접착 시스템을 사용하여 치관 파절편을 재부착함으로 써 생물학적으로 최소한으로 침습적인 치료를 하는 방법도 있다. 만약 파절의 정도가 치은 연하로 깊은 경우 발치나 치관절제 술을 이용한 치근의 유지 등을 고려할 수 있다. 본 증례는 치관-치근파절로 내원한 12세 환아로 섬유강화형 포스트를 사용하여 치관 파절편 재부착을 시행하였으며 양호 한 경과를 보여 이를 보고하는 바이다.

For hot operation of advanced spent fuel conditioning process(ACP), the analysis of radiation-resistant Requirements effect and the system design process are required to design equipment to operate to operate reliably in a gamma radiation environment such as hot cell. To analysis the effects of radiation for ACP, we used the SCALE codes which were certified by Nuclear Regulatory Commission(NRC). The source term was calculated which reflects the features of target nuclear fuels using ORIGEN-S, a module of the SCALE code, and the gamma dose rates were calculated by using the QADS modules, considering the geometry of process equipment respectively. the results are shows that the value was maximum 3.03 ㏉/h from the rod storage box in hot cell, maximum 0.6 ㏉/h from the metallizer, and maximum 72.0 ㏉/h from the vol-oxidizer. Considering those values, the design methods for shielding and repositioning the major equipments and components should be induced, and, the preventive maintenance for components before failure actually occurs should be minimized the effects of radiation.
