本研究的目的是确定五种修复系统与牙本质/牙骨质结合时的相对微渗漏。为了测定微渗漏，我们在65颗牙（每种材料10-15颗）牙髓-牙釉质交界处以下的面表面制备V类空腔制剂并修复。根尖密封，牙齿涂上指甲油，除了修复体周围1毫米外，标本在2%亚甲基蓝溶液中热循环（x500）。将包括修复体在内的根切片溶解在酸中，用分光光度法测定染料的浓度。微漏值排序为：Dyract < OptiBond < AeliteBond < All-Bond 2 < ScotchBond。综上所述，Dyract在牙本质/牙骨质交界面处的微渗漏最小，在临床情况下可以增加修复体的寿命，没有或减少继发龋。
The purpose of this study was to determine the relative microleakage of five restorative systems when bonded to dentine/cementum. For the microleakage determination Class V cavity preparations were prepared on the facial surfaces of 65 teeth (10-15 for each material) below the cemento-enamel junction and restored. The root apices were sealed, the teeth coated with nail varnish except for 1 mm surrounding the restorations and the specimens were thermocycled (x500) in 2 per cent methylene blue solution. Root sections including the restorations were dissolved in acid and the concentrations of the dye determined spectrophotometrically. The sequence of the microleakage values were: Dyract < OptiBond < AeliteBond < All-Bond 2 < ScotchBond. It is concluded that Dyract had the lowest microleakage at dentine/cementum interface, which may increase the longevity of the restorative in the clinical situation, with no, or less secondary caries.
