The aim of this study was to evaluate the biocompatibility of the root canal sealer Epiphany in rat subcutaneous tissues.
Polyethylene tubes were filled with the sealer (I: Epiphany; II: photoactivated Epiphany; III: Epiphany associated with self-etch primer; IV: photoactivated Epiphany associated with primer; and V: control group) and later implanted into 4 different regions of the dorsum of 15 adult male rats (Rattus novergicus, Albinus Wistar). After 7, 21, and 42 days, 5 animals were killed, obtaining 4 samples per group, in addition to the control group, at each analyzed time.
In all periods, Epiphany induced a mild inflammatory reaction. However, in group II, in which the primer was not used, extensive necrosis and a moderate to intense inflammatory reaction were observed, mainly after 7 and 21 days.
Epiphany sealer appears biocompatible when tested on rat subcutaneous tissues.
本研究旨在评估根管封闭剂Epiphany在大鼠皮下组织中的生物相容性。
将聚乙烯管填充密封剂(I组:Epiphany;II组:光活化Epiphany;III组:Epiphany与自酸蚀底漆联合使用;IV组:光活化Epiphany与底漆联合使用;V组:对照组),随后植入15只成年雄性大鼠(挪威大鼠,白化Wistar大鼠)背部的4个不同区域。在7天、21天和42天后,每组处死5只动物,除对照组外,在每个分析时间点每组获取4个样本。
在所有时间段,Epiphany均引发轻度炎症反应。然而,在未使用底漆的II组中,观察到广泛坏死以及中度至重度炎症反应,主要出现在7天和21天后。
在大鼠皮下组织进行测试时,Epiphany封闭剂表现出生物相容性。
