초록

이 연구의 목적은 알카자이트 수복재와 자이오머에서 방출되는 불소가 상아질 접착층을 투과하는 유리되는 양을 측정하고 비교하는 것이었다. 알카자이트 수복재와 자이오머 및 불소 미함유 복합레진의 시편을 각 재료 당 20개씩 제작하여 그 중 10개의 시편에 상아질 접착제를 도포하였다. 만들어진 시편을 2.0 mL의 탈이온수가 들어있는 폴리에틸렌튜브에 넣고 37.0℃ 항온수조에 연구 기간동안 보관하였다. 보관 후 1일, 3일, 7일, 14일, 21일, 28일째에 불소 유리량을 측정하였으며 매 측정 후 탈이온수를 교체하였다. 상아질 접착제층 두께의 적절성은 시편을 추가로 제작하여 전계방사형 주사전자현미경으로 관찰하여 평가하였다. 알카자이트 수복재와 자이오머에 상아질 접착제를 도포한 경우 접착제가 불소의 유리를 완전히 차단하지는 않았지만, 유리된 불소의 양이 현저히 감소하였다. 28일간 측정한 알카자이트 수복재의 불소 유리량은 상아질 접착제의 유무와 관계없이 자이오머보다 크게 나타났다.

This study evaluated the fluoride release of alkasite restorative material (ARM) and giomer penetrating the dentin adhesive layer. Twenty specimens were prepared for each restorative material, and dentin adhesive with uniform thickness was applied to half of them. The prepared specimens were placed in a polyethylene tube containing 2.0 mL of deionized water and deposited in a 37.0℃ water bath for the study duration. The amount of fluoride release was measured on the 1st, 3rd, 7th, 14th, 21st, and 28th days after deposition. The dentin adhesive applied to the ARM and giomer could not completely block the fluoride release; however, it significantly reduced its amount. The cumulative amount of fluoride release of the ARM after 28 days was higher than that of the giomer regardless of the application of dentin adhesive.
