MTA和氢氧化钙添加剂对AH +密封胶的粘结强度有影响吗?
本研究的目的是通过在AH Plus中加入不同水平的MTA和Ca(OH)2,并与未改性的AH Plus、Total Fill和MTA Fillapex进行比较,以评估AH Plus和Ca(OH)2的粘结强度。制备了91颗单根人上颌中牙,并对粘结强度进行了评估(n=70): AH Plus;MTA Fillapex;TotalFill;4种实验密封剂(AH + + 5% Ca(OH)2;AH + 5% MTA;AH + 10% Ca(OH)2;AH + 10% MTA) (n=10)。从每个根样品中获得3片厚度为1mm的薄片,并使用推出试验测量测试材料的粘结强度。数据分析采用单因素方差分析和事后Tukey检验(p=0.05)。AH + +10% MTA组和MTA圆尖组平均推出值最高,最低(p<0.05)。 No statistically significant difference was found between AH-plus and the experimental sealers (p>0.05). It was observed that adding 5% or 10% of Ca(OH)2 or MTA to AH-plus had no negative effect on the bond strength of AH plus.
