Abstract

Deterioration of long-term dentin adhesion durability is thought to occur by hydrolytic degradation within hydrophilic domains of the adhesive and hybrid layers. This study investigated the hypothesis that priming the collagen network with an organic solvent displace water without collapse and thereby obtain good bond strength with an adhesive made of hydrophobic monomers and organic solvents. Three experimental adhesives were prepared by dissolving two hydrophobic monomers, bisphenol-A-glycidylmethacrylate (Bis-GMA) and triethyleneglycol dimethacrylate (TEGDMA), into acetone, ethanol or methanol. After an etching and rinsing procedure, the adhesives were applied onto either wet dentin surfaces (wet bonding) or dentin surfaces primed with the same solvent (solvent-primed bonding). Microtensile bond strength (MTBS) was measured at 48 hrs, 1 month and after 10,000 times of thermocycles. The bonded interfaces were evaluated using a scanning electron microscope (SEM). Regardless of bonding protocols, well-developed hybrid layers were observed at the bonded interface in most specimens. The highest mean MTBS was observed in the adhesive containing ethanol at 48 hrs. With solvent-primed bonding, increased MTBS tendencies were seen with thermo cycling in the adhesives containing ethanol or methanol. However, in the case of wet bonding, no increase in MTBS was observed with aging.

장기적인 상아질 접착의 내구성 악화는 접착층과 혼성충의 친수성 부위에서의 가수분해에 의해 일어나는 것으로 보고 되고 있다. 본 연구의 가설은 콜라겐 망상체를 유기용매로 프라이밍하면 콜라겐 조직을 붕괴시키지 않고 수분을 밀어내고 소수성 단량체와 유기용매로 이루어진 접착제가 침투하여 접착강도를 얻을 수 있다는 것이다. 두 소수성 단량체인 Bisphenol-A-glycidylmethacrylate (Bis-GMA)와 triethyleneglycol dimethacrylate (TEGDMA)를 아세톤, 에탄올 또는 메탄올에 용해시켜 세 가지의 실험용 접착제를 준비하였다. 산 부식과 수세과정 후에, 접착제를 습윤 상아질 표면(습윤 접착)이나 동일한 용매로 프라이밍 된 상아질 표면(용매 프라이밍 접착)에 적용하였다. 48시간 후와 1개월 후, 및 10,000회의 열순환 후에 미세인장결합강도를 측정하였다. 접착계면은 주사전자현미경을 이용하여 관찰하였다. 접착 방법에 무관하게 대부분의 시편의 접착계면에서 잘 발달된 혼성층을 관찰할 수 있었고, 가장 높은 평균 미세인장결합강도는 에탄올을 포함하는 접착제의 48시간 후 시편에서 관찰되었다. 용매를 이용하여 프라이밍하는 접착 방법에서는 에탄올이나 메탄올을 포함하는 접착제에서 열순환 후에 미세인장접착강도가 증가하는 경향을 보였다. 그러나, 습윤 접착의 경우에는 시효처리 후 미세인장결합강도의 증가가 관찰되지 않았다. 본 연구에서 에탄올을 이용한 상아질 프라이밍으로 우수한 접착력을 얻을 수 있었고, 열순환 후 접착력 이 더욱 증가하였다.
