Abstract

The purpose of this study was to evaluate the effect of increasing application time of single bottle adhesives (SBA) to microtensile bond strength (MTBS) of dried dentin. To expose the superficial dentin surfaces, human molars were sectioned perpendicular to the long axis of tooth. $32\%$ phosphoric acid gels were applied for 15s and rinsed. The teeth were randomly assigned to 3 groups ; S group (Single Bond), O group (One-Step), P group (Prime & Bond NT). Each group was divided to 3 subgroups (W: dentin wipe with wet gauge and light cured immediately, D, dentin dried for 30s and light cured immediately, 30: dentin dried for 30s and light cured after applying SBA for 30s). Composite resin was built up on the dentin surface and sectioned to obtain 20 specimens with $1mm^2$ cross sectional area and the MTBS was measured. For Single Bond, the mean MTBS of S-W and S-30 group were higher than that of S-D group statistically (P<0.05). For One-Step, the mean MTBS of O-D group was statistically lower than that of O-W group (P<0.05). For Prime & Bond NT, the mean MTBS of P-30 group was statistically lower than that of P-D group (P<0.05).

본 연구는 친수성 용매가 함유되어 있는 3종의 단일병 접착제의 적용 시간을 증가시켰을 때, 건조 상아질에 대한 재습윤의 효과가 있는지를 미세인장 결합강도의 측정을 통해 알아보고자 시행하였다. 실험대상은 최근에 발거한 상하악의 대구치로, 교합면 1/3부위의 치질을 치아 장축에 수직으로 절단하여 상아질을 노출시킨 후, $32\%$인산 (Unietch, Bisco Inc., Schaumburg, IL, USA)으로 15초간 산부식 하고 수세하였다. 치아는 무작위로 S군 (Single Bond), O군 (One-Step), P군 (Prime & Bond NT)으로 분류하였고, 각 군은 다시 3군 (W: 상아질 표면의 남아있는 과잉의 물을 수분에 적신 거즈를 이용하여 제거한 후, 즉시 단일병 접착제를 적용하고 광중합, D : 30초간 건조 한 후 즉시 단일병 접착제를 적용하고 광중합, 30: 30초간 건조 한 후 단일병 접착제를 30초간 적용하고 광중합)으로 소 분류하였다. 접착제 도포 후, 복합레진을 축조하고 접착계면이 $1mm^2$가 되도록 절단하여 각 군당 20개의 표본을 사용하여 미세인장 결합강도를 측정하였다. 5군,0군의 30초 적용군 (S-30, O-30)은 건조군 (S-D, O-D)보다 높은 미세인장 결합강도를 보였으며, S-30군의 경우 S-D군보다 통계학적으로 유의성 있게 높았다 (P<0.05). 하지만, P군의 30초 적용군 (P-30)은 건조군 (P-D)에 비해 미세인장 결합강도가 통계학적으로 유의성 있게 감소하였다 (P<0.05).
