Abstract：
UNASSIGNED: The present study evaluated the effect of a bioceramic intracanal medicament (Bio-C Temp) on the push-out bond strength of bioceramic cements.
UNASSIGNED: Forty-eight human single-canaled premolars were prepared and randomly divided into three groups: Group (A) received no intracanal medicament; Group (B) calcium hydroxide (CH); and Group (C) Bio-C Temp. After medicament removal, the roots were sectioned transversely. The slices in each group were separated into two subgroups (n = 16): in Subgroup (1), mineral trioxide aggregate (MTA) was placed, and in Subgroup (2) Bio-C Repair. Push-out bond strength was determined using a universal testing machine, applying a constant compressive force on the cement until bond failure. The failure mode was also evaluated. Data were analyzed using the Chi-square test and two-way ANOVA followed by Tukey\'s post hoc tests. The level of significance was set at 5%.
UNASSIGNED: The pushout bond strength of Bio-C Repair was significantly higher than that of MTA irrespective of intracanal medication (p = 0.005). The placement of Bio-C Temp was associated with significantly lower bond strength (p = 0.002, p = 0.001).
UNASSIGNED: Bio-C Repair showed better bond strength compared to MTA, irrespective of intracanal medication. Bio-C Temp intracanal medicament, however, decreased the bond strength of both these cements.

摘要：
■本研究评估了生物陶瓷腔内药物（Bio-CTemp）对生物陶瓷水泥的挤出粘结强度的影响。
■制备了48个人类单管前磨牙，并随机分为三组：组（A）不接受肛门内药物；组（B）氢氧化钙（CH）；和组（C）Bio-CTemp。取出药物后，根部被横切。每组切片分为两个亚组(n=16):亚组(1),放置矿物三氧化物骨料（MTA），亚组（2）Bio-C修复。使用万能试验机确定推出粘结强度，在水泥上施加恒定的压缩力，直到粘结破坏。还评估了故障模式。数据采用卡方检验和双向方差分析，然后进行Tukey的事后检验。显著性水平设定为5%。
■无论肛门内用药，Bio-C修复的推出粘结强度均显着高于MTA（p=0.005）。Bio-CTemp的放置与显着降低的粘结强度相关（p=0.002，p=0.001）。
■与MTA相比，Bio-C修复显示出更好的粘结强度，不管肛门内药物。Bio-CTemp肛门内药物，然而,降低了这两种水泥的粘结强度。
