Diastema closure with direct composite: architectural gingival contouring
김연화,조용범,Kim, Yeon-Hwa,Cho, Yong-Bum The Korean Academy of Conservative Dentistry 2011 Restorative Dentistry & Endodontics Vol.36 No.6
전치부 치간이개를 치료할 때 가장 어려운 것은 레진으로 축성 후 치아 사이의 "black triangle"없이 치간공극을 메우는 것이다. 이를 위해서는 치경부 형태와 접촉점의 위치에 기초하여 치은 형태를 결정하는 것이 중요하다. 이 증례보고는 적절한 접촉점을 형성하기 위해 비침습적 방법을 사용하여 접촉점의 위치를 설정하였다. 또한 치은-치아 사이에 위치한 Mylar strip을 이용한 기존의 방법을 바꾸어 자연스러운 형태를 갖도록 변형하였다. Mylar strip을 치은연 상방으로 약 1 mm 정도 되게 치은열구에 위치시키고 작은 면구를 치은과 그 사이에 위치시켜 출현윤곽(emergence contour)을 부여하였다. 이와 같은 변형된 방법은 적절한 출현윤곽과 치은형태를 형성하는데 유용하였으며, 임상적용에 유효하였다. One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.

찻주전자가 지닌 조형성은 조형예술의 새로운 의미이고 형상이며 이것의 조형이념과 조형형식은 새로운 생활환경을 개선하는 최선의 방법이라 볼 수 있다. 또한 찻주전자와 같은 실용적인 욕구와 심미적인 이념을 충족시키기 위한 현실적 형상으로서의 인공적인 조형물은 구성과 구조의 유기적이며 기능적인 관계에 영향을 주게 된다. 따라서 이것의 관계를 상관적 의미로 재해석하여 새로운 만듦의 세계를 창출하는 문제는 중요한 의미를 지닌다. 조형구조와 조형의 개념과 표상을 이해하기 위하여 찻주전자를 해석, 진단하는 것은 이것이 지니고 있는 조형성에 나타난 물질적 표현성과 구조로서의 형식과 시각요소로서의 상징을 대상으로 상호관계의 변화를 이해하는 것이다. 형태를 이루는 것과 재료의 설정 및 기법 개발을 통한 선행적, 창조적 조형표현을 인식하게 되는 것이다. 연구방법으로는 찻주전자의 조형 개념과 실체를 분석하고 형상적 형태로서의 구조해명을 통해 이것이 지니고 있는 유형과 문양의 실체적 조형 형식을 진단하였다. 이를 통해 찻주전자가 지니고 있는 자연미, 의식성, 기하학적 조형미와 함께 정갈하고, 명확한 인위적 조형성의 실용 가치를 확인하였다. 그럼으로써 찻주전자에 나타난 조형의 이념과 형식의 체계를 이해하는 것이 조형창조 과정에 새로운 형상과 가치로 존재하고 있음을 확인 하게 되었다. The metaphysical formality of teapot is a new meaning in formative arts and its idea and forms of formality are the best way to improve life environment. Artificial sculpture like teapot which satisfies both practical use and aesthetic desire has impact on the functional and organic relations between construction and structure. In that sense, it is an important thing to reinterpret the making of the physical concept a metaphysical structure has through their correlational meaning and to create another possible world of the making. In interpreting and analyzing teapot to understand the concept and idea of formality and formal structure, we focus on the understanding of changing correlations about symbols as materialistic expressivity shown on metaphysical formality and forms as a structure and emblem as visual element and as a result, we could recognize creative and preceding expression activities of structure through selections of elements and techniques development and combinations of forms. Through the analysis of the formality concept and essence of teapot and the explanation of its structure as a formal structure, a comprehensive formality of types or patterns of tea pot was studied. Through this, it has been identified that teapot shows the balance among its natural beauty, consciousness beauty and geometrical beauty of formality and also gives a value as practical use of simple and clear artificial formality accompanied by artless art. The result is that to understand a system of structure and the idea of formality expressed on teapot exists as new shapes and values in the course of creation of structure.

A survey on primary school pupils' recognition on dental hygiene education and the 1st molar health capacity of them was made in 1997. This study has been performed following continuous dental sanitary education for primary school pupils for five years from 1997 through 2001 based on the '97 survey. Following results were drawn through comparative analyses of data obtained during the survey period 1. Approx 70.77% of the examinees have experienced decay missing feeling (DMF) in the year 2001, suggesting a good effectiveness of dental hygiene education compared with 92.1% of DMF rate in 1997. 2. Primary school pupils' knowledge and recognition on dental hygiene and management were found to be enhanced through dental sanitary education, resulting in change of their eating habits and their consciousness on dental health. 3. It has been found that the 1st molar health capacity improved and the rate of DMF significantly decreased every year during the period. 4. Improvement of dental health was observed in pupils who gave a right answer to the question "what is plaque?" considering the 1st molar health capacity and DMF rate. It has been found that the 1st molar health capacity of pupils who recognize plaque were not correlated with primary dental conservation or maintenance of permanent dentals (P<0.05). 5. Grade level analysis revealed that low degree of the 1st molar health capacity was observed in a higher grade, but significant improvement of dental health capacity was observed in the same grade level rather in 2001 than in 1997.
