초록
이 연구는 와동이 형성된 초기 우식 병소를 재현하여 레진 침투법 처리 후 복합 레진과 레진 강화형 글라스아이오노머 시멘트로 수복을 시행하고 그에 따른 미세누출의 정도를 평가하기 위해 수행되었다. 건전한 20개의 발치된 제3대구치에 인공 우식을 유발하고 무작위로 I군과 II군으로 나누었다. 각 치아의 근원심면에 각각 와동을 형성하여 무작위로 실험군과 대조군으로 설정하였다. 실험군에는 레진 침투법 전처리를 시행하였고 대조군에는 전처리 없이 수복하였으며, I군은 유동성 레진을, II군은 레진 강화형 글라스아이오노머 시멘트로 수복하였다. 열순환 및 질산은 침지 후 μ-CT로 미세누출 양상을 확인하였다. 질산은 침투 깊이는 I군과 II군 모두에서 실험군이 대조군에 비하여 낮았으나, 통계적 유의성은 II군에서만 확인되었다. 재료 별로 비교 시 실험군과 대조군 모두 I군에 비해 II군의 침투 깊이가 통계적으로 유의하게 낮았다. 인공적으로 재현한 와동성 초기 우식 병소에 대하여 수복 전 레진 침투법 전처리를 하는 것은 치면과 수복물 계면에서의 미세누출을 감소시켰다. 레진 침투법 전처리 후 레진 강화형 글라스아이오노머 시멘트로 수복하였을 때 유동성 레진에 비하여 미세누출이 감소하는 결과를 얻었으며 실험적인 한계를 고려할 필요가 있다.
Abstract
This study was performed to evaluate the restoration combined with resin infiltration (RI) of early cavitated smooth surface caries lesion in terms of microleakage. Flowable resin and resin-modified glass ionomer cement (RMGIC) were compared. Sound 20 extracted 3rd molars were divided into 2 groups randomly. Artificial decalcified lesion was induced. Cavities were prepared on the mesial and distal surfaces, and randomly set as experimental and control group. RI was applied to the experimental group before cavity restoration. The control group was restored without RI. In group I and II, flowable resin and RMGIC was used for restoration respectively. After thermocycling and silver nitrate immersion, microleakage was assessed by μ-CT. Depth of microleakage was lower in experimental group than control group only in group II (p = 0.05). Microleakage depth was lower in group II than group I in both experimental and control groups (p = 0.05). RI pretreatment before restoration of early cavitated caries lesions might reduce the microleakage and help long-term maintenance of restoration. In this study, RMGIC was less polymerization shrinkage. Restoration with RMGIC after RI pretreatment reduced the microleakage of the restoration compared to the flowable resin.
