本研究的目的是探讨牙本质剩余厚度（RDT）和长期水分储存对牙本质结合强度的影响。27颗三磨牙随机分为3组：Clearfil Bond SE ONE组（SE1, Kuraray Noritake Dental，冈山，日本）、G-Bond plus组（GB， GC，东京，日本）和Clearfil Mega Bond组（MB, Kuraray Noritake Dental）。粘接试样在37℃的水中保存24小时。然后将牙齿垂直于粘接界面切割成梁。采用数字卡尺测量各光束的RDT。在24 h和1年的水储存后，以1 mm/min的十字头速度进行微拉伸粘结强度测试。除了24 h MB组外，较厚的RDT在一/两步自蚀刻材料中产生更高的结合强度。然而，所有材料的水储存时间和RDT都会影响µTBS。
The purpose of this study was to investigate the effect of remaining dentin thickness (RDT) and long term water storage on dentin bond strength in-vitro. Twenty-seven third molars were randomly divided into 3 groups: Clearfil Bond SE ONE (SE1, Kuraray Noritake Dental, Okayama, Japan), G-Bond plus (GB, GC, Tokyo, Japan) and Clearfil Mega Bond (MB, Kuraray Noritake Dental). Bonded specimens were stored in water at 37ºC for 24 h. The teeth were then sectioned perpendicular to the adhesive interface to produce beams. RDT of each beam was measured digital calliper. Microtensile bond strength testing was carried out at a crosshead speed of 1 mm/min after 24 h and 1 year water storage. Thicker RDT produced higher bond strengths with one/two-step self-etch materials tested except for the group of 24 h MB. Nevertheless water storage time and RDT affected µTBS in all materials used.
