Abstract

The purpose of this study is to compare the shear bond strength of repaired composite resin with different bonding agents and evaluate the effect of bonding agents on composite repair strength. Forty composite specimens (Z-250) were prepared and aged for 1 week by thermo cycling between 5 and $55^{\circ}C$ with a dwell time of 30s. After air abrasion with $50\;{\mu}m$ aluminum oxide, following different bonding agents were applied (n = 10); SB group: Scotchbond multipurpose adhesive (3 step Total-Etch system); XE group: Clearfil SE bond (2 step Self-Etch system); XP group: XP bond (2 step Total-Etch system); XE group: Xeno III (1 step Self-Etch system). After bonding procedure was completed, new composite resin (Z-250) was applied to the mold and cured. For control group. 10 specimens were prepared. Seven days after repair, shear bond strength was measured. Data was statistically analyzed using one-way ANOVA and Tukey's test (p<0.05). The means and standard deviations of shear bond strength (MPa ${\pm}$ S.D.) per group were as follows: SB group: 17.06; SE group: 19.10; XP group: 14.44; XE group: 13.57; Control Group: 19.40. No significant difference found in each group. Within the limit of this study, it was concluded that the different type of bonding system was not affect on the shear bond strength of repaired composite resin.

이 연구의 목적은 서로 다른 접착제들로 수리된 복합 레진의 전단 결합 강도를 비교하고, 접착 시스템이 복합레진의 수리 강도에 미치는 영향을 평가하기 위한 것이다. 40개의 복합 레진 시편 (Z-250)을 준비하였으며, 1주일 동안 열순환을 시행한 후, $50\;{\mu}m$ 알루미나 입자로 샌드 블라스팅 하였다. 이 시편들을 네 개의 그룹으로 나누었으며 (n = 10), 다음과 같은 서로 다른 종류의 접착제를 각각 적용하였다; SB 그룹 : Scotchbond multipurpose ; SE 그룹 : Clearfil SE bond ; XP 그룹 : XP bond ; XE 그룹 : Xeno III. 접착 과정을 완료한 후에, 새로운 레진 (Z-250, 3M ESPE)을 몰드에 적용하여, 광조사 하였다. 대조군으로, 접착 과정 없이 10개의 시편을 준비하였다. 7일 동안 열순환을 시행한 후 전단 결합 강도를 측정하였고, 파절 양상을 조사하였으며, 다음과 같은 결과를 얻었다. 1. 기존 복합 레진과 수리용 복합 레진 사이의 전단 결합 강도는 접착제 종류에 따른 유의한 차이를 보이지 않았다. 2. 재료의 응집 강도 (대조군)와 수리한 결합 강도 (실험군) 사이에 유의한 차이를 보이지 않았다. 3. 파절 양상은 대부분 응집성 파절 또는 혼합 파절을 보였다.
