Abstract

Biodentine? is currently and regularly used as a direct/indirect capping material and dentine substitute under a resin composite direct restoration. The present study investigated the influence of Biodentine? maturation time on its shear bond strength to a resin-based composite restorative material.

One hundred fifty PTFE tubes were divided into 2 groups (n?=?75), and each group of tubes was filled with a different substrate material (Biodentine? or GC Fuji IX glass ionomer cement). The tubes were subsequently divided into subgroups (n?=?25) that were used to test different substrate maturation times (early, 12?min; medium, 72?h; and delayed, 2?weeks). A resin-based composite restorative material was bonded to the substrates using a 3-step etch and rinse adhesive system (Optibond FL, Kerr), and the bond was tested for shear bond strength.

The Biodentine?/12-min group showed a very low shear bond strength of 2.796?±?2.704?MPa. The values for the Biodentine?/72-h and Biodentine?/2-weeks groups increased as the maturation time interval increased and were 7.986?±?2.100?MPa and 10.553?±?3.281?MPa, respectively. The differences between the Biodentine?/12-min group and the Biodentine?/72-h and Biodentine?/2-weeks groups are statistically highly significant (p?<?.001). The difference between the Biodentine?/72-h group and the Biodentine?/2-weeks group is statistically significant (p?<?.05).

Bonding with Biodentine? that has matured for 72?h results in a statistically significant increase in shear bond strength and yields a more clinically acceptable bond between the two materials.

硅酸钙基水泥(Biodentine™)成熟时间对树脂粘合的影响:一项体外研究

Biodentine吗?目前经常用作树脂复合材料直接修复下的直接/间接盖层材料和牙本质替代品。本研究探讨了百奥汀?成熟时间对树脂基复合修复材料剪切粘接强度的影响。150个聚四氟乙烯管分为2组(n = 75)，每组管填充不同的衬底材料(Biodentine?或GC富士IX玻璃离子水泥)。这些试管随后被分成亚组(n?= 25)，用于测试不同的底物成熟时间(早期，12?min;媒介,72 ? h;推迟了，2周半)。使用三步蚀刻和漂洗粘合剂系统(Optibond FL, Kerr)将树脂基复合修复材料粘合到基材上，并测试粘合剂的剪切强度。Biodentine吗?/12 min组剪切强度很低，为2.796±2.704 MPa。百妥定的值是多少?/72-h和biotenine ?/2周组随着成熟时间间隔的增加而增加，分别为7.986±2.100?和10.553±3.281?分别MPa。百妥定的区别是什么?/12 min组和百妥定?/72-h和biotenine ?/2周组差异有显著统计学意义(p <?.001)。百妥定的区别是什么?/72 h组和Biodentine?/2周组差异有统计学意义(p <? 0.05)。和百欧汀结合?已经成熟到72岁了?H在统计上显著增加剪切粘合强度，并在两种材料之间产生更临床可接受的粘合。
