Abstract

The purpose of this study was to evaluate the effect of Er,Cr:YSGG laser irradiation with hypersensitivity mode on microtensile bond strength of composite resin. Twenty extracted permanent molars were randomly assigned to six groups, according to the irradiation of Er,Cr:YSGG laser, adhesive system (Optibond FL or Clearfil SE bond) and application time of etchant (15 sec or 20 sec). Then composite resin was build up on each conditioned surface. The restored teeth were stored in distilled water at room temperature for 24 h and twelve specimens for each group were prepared. All specimens were subjected to microtensile bond strength and the fracture modes were evaluated. Also, the prepared dentin surface and laser irradiated dentin surface were examined under SEM. The results were as follows: 1. The microtensile bond strength of laser irradiated group was lower than that of no laser irradiated group. 2. Regardless of laser irradiation, the microtensile bond strength of Optibond FL was higher than that of Clearfil SE bond. And the microtensile bond strength of 20 sec etching group was higher than that of 15 sec etching group when using Optibond FL. 3. The SEM image of laser irradiated dentin surface showed prominent peritubular dentin, opened dentinal tubules and no smear layer.

이 연구의 목적은 상아질 지각과민증 모드의 Er,Cr:YSGG 조사가 복합레진 수복물의 미세인장 결합강도에 미치는 영향을 평가하는 것이다. 20개의 발거된 대구치를 사용하여 Er,Cr:YSGG 레이저 적용 유무와 사용된 접착제 시스템(Optibond FL과 Clearfil SE bond), 산의 적용 시간(15초와 20초)에 따라 여섯 그룹으로 나누었다. 노출된 교합면 상아질에 레이저 조사 후 접착제를 도포하고 복합레진으로 수복하였다. 24시간 동안 실온의 증류수에 보관 후 각 그룹 당 12개의 시편을 준비하였다. 모든 시편의 미세인장 결합강도를 측정하고 파절 양상을 관찰하였다. 더불어 레이저를 조사한 시편과 조사하지 않은 시편을 주사현미경을 이용하여 관찰하여 다음과 같은 결과를 얻었다. 1. 레이저를 조사한 그룹은 레이저를 조사하지 않은 그룹보다 낮은 미세인장 결합강도를 나타내었다. 2. 레이저 조사 유무와 관계없이, Optibond FL이 Clearfil SE bond보다 높은 미세인장 결합강도를 나타냈으며, Optibond FL을 사용했을 때 산부식 시간이 20초인 경우가 15초인 경우보다 더 높은 값을 나타내었다. 3. 레이저를 조사한 상아질의 SEM 사진은 관간상아질보다 관주상아질이 더 두드러져 보이며, 상아세관이 열려있으며 도말층은 관찰되지 않았다.
