5급와동 복합레진 수복물에서 충전방법이 변연부접합성에 미치는 영향을 평가하기 위해

서, 발거된 소구치 30개를 대상으로 치경부에 5급와동을 형성하고 광중합 복합레진인 Hel

iosit**(R) 을, 한번에 충전하는 방법(bulk-pack placement), 치경부에서 교합면부로 첨

가하면서 충전하는 방법(apical to occlusal layering placement) 협설측으로 첨가하면서

충전하는 방법(buccolingual layering placement)에 의하여 충전하고 수복물과 치질사이

의 접촉면에서의 접합성을 주사전자현미경으로 관찰하여 다음과 같은 결론을 얻었다.

1. 법랑질에서의 변연부접합성은 충전방법에 관계없이 모두 우수하게 나타났다.

2. 상아질에서의 변연누출은 충전방법에 관계없이 모두 관찰되었다.

3. 광중합 복합레진에서 충전방법에 따른 변연부접합성의 차이를 관찰할 수 없었다.





A Scanning Electron Microscopic Study for the Effect of the Filling Techniques of

Composite Resin on the Marginal Adaptation



Hyun kyung Cho, D.D.S.

Department of Dentistry, Graduate School, Yonsei University

(Directed by Professor Chung Suck Lee D.D.S., Ph.D.)



The purpose of this study was to evaluate the marginal adaptation of Class V

resin restorations by the filling techniques. The cavities were filled with

Heliosit**(R) light curing composite resin system in accordance with the following

three filling techniques-bulk-pack placement technique, apical to occlusal layering

placement techique, and buccolingual layering placement technique.

And the interface between the restoration and the tooth structure was observed

with scanning electron microscope.

The following results were obtained.

1. Marginal adaptation of enalmel showed excellent irrespective of the filling

techniques.

2. Marginal leakage of dentin was observed irrespective of the filling

techniques.

3. No difference of marginal adaptation according to the filling techniques was

observed in light curing composite resin.
