초록

본 연구에서는 접착레진의 부가적인 도포가 레진 시멘트의 결합강도에 미치는 영향을 연구하였다. One-Step Plus와 Choice, Single Bond와 Rely X ARC, One-Up Bond F와 Bistite II DC를 사용하였고 접착레진으로 D/E Bonding resin과 Pre-Bond Resin을 선택하였다. 적용 및 광중합 유무에 따라 12개의 군을 설정하였다. 제 3대구치의 건전한 상아질 면에 간접 복합레진 수복물을 제작하여 접착을 시행하고$1\;{\times}\;1\;mm^2$의 시편을 만들어 미세인장강도를 측정하였다. 또한 투과전자현미경으로 접착계면을 관찰하였다. 그리하여 다음과 같은 결론을 얻을 수 있었다. 1. Single Bond와 Rely X ARC, 그리고 One-Step Plus와 Choice를 조합하고 광중합을 시행한 군에서, 접착 레진을 부가적으로 도포할 경우 미세인장강도가 증가하였다. 2. One-Up Bond F와 Bistite II DC를 조합한 군에서 접착레진의 부가적인 도포에 의한 미세인장강도의 차이는 나타나지 않았다. 3. 광중합을 시행한 군들 중, One-Step Plus와 Choice를 조합한 군이 다른 군보다 높은 미세인장결합강도를 보였다. 4. 자가중합만을 시행한 군간에는 접착레진의 부가적인 도포에 의한 차이가 나타나지 않았다. 투과전자현미경 관찰을 시행하여 광중합을 시행하고 접착레진을 부가적으로 도포한 실험군에서 미세누출이 감소하고 접착층의 두께가 증가한 것을 확인할 수 있었다. 본 연구결과 완전산부식 상아질 접착제와 이중중합 레진 시멘트를 사용할 경우 부가적인 접착레진의 도포가 임상적으로 유용할 수 있다는 사실을 확인할 수 있었다.

The objective of this study is to evaluate the effect of an additional application of bonding resin on the bond strength of resin luting cements in both the light-cure (LC) and self-cure (SC) modes by means of the ${\mu}TBS$ tests. Three combinations of One-Step Plus with Choice, Single Bond with Rely X ARC, and One-Up Bond F with Bistite II were used. D/E resin and Pre-Bond resin were used for the additional application. Twelve experimental groups were made. Three mandibular $3^{rd}$ molars were used in each group. Indirect composite blocks were cemented on the tooth surface. $1\;{\times}\;1\;mm^2$ dentin-composite beam for ${\mu}TBS$ testing were made and tested. When total-etching dentin adhesives were used, an additional application of the bonding resin increased the bond strength (P < 0.05). However, this additional application didn't influence the bond strength of self-etching dentin adhesives (P > 0.05). In conclusion, the results suggest that an additional application of the bonding resin increases bond strength and enhances quality of bonding when using total-etching dentin adhesives.
