Microorganisms are the main cause of failure of endodontic treatment. When retreatment fails periapical surgery followed by retrograde filling is done to seal the apex. A root-end filling material should have antimicrobial property as well as bioactive properties necessary for healing, repair, and regeneration of the apex.
The aim of this study was to evaluate the antibacterial and antifungal efficacy of three bioactive root-end filling materials: mineral trioxide aggregate (MTA) Plus, Biodentine, Endosequence root repair material (ERRM) against and .
and standard bacterial strains were used. 100 μl was taken from liquid cultures of and planted in Mueller-Hinton agar and the same amount of was planted in Sabouraud dextrose agar by lawn culture. MTA Plus, Biodentine, and ERRM were aseptically filled into the opened pits. Following this, the media were kept in the drying oven at 37°C for 24, 48, and 72 h and the diameters of the inhibition zones were measured.
Statistical analysis was carried out by Kruskal-Wallis, (Mann-Whitney), Friedman, and (Wilcoxon-sign) test.
Among the three groups, the antimicrobial activity of Biodentine against was statistically higher than MTA Plus and ERRM ( < 0.05). Antifungal activity of MTA Plus against was statistically higher than Biodentine and ERRM ( < 0.05). ERRM showed the smallest inhibition zone against and among the three groups ( < 0.05).
Biodentine exhibited the greatest antimicrobial activity and MTA Plus exhibited the greatest antifungal activity among the three groups. ERRM exhibited the least antibacterial and antifungal activity among the three groups.
微生物是牙髓治疗失败的主要原因。当再治疗失败时,需进行根尖手术并随后进行倒充填以封闭根尖。根尖充填材料应具有抗菌性能以及根尖愈合、修复和再生所需的生物活性特性。
本研究的目的是评估三种生物活性根尖充填材料:矿物三氧化物凝聚体(MTA)Plus、BioDentine、Endosequence根修复材料(ERRM)对[具体细菌名称1]和[具体细菌名称2]的抗菌和抗真菌效果。
使用[具体细菌名称1]和[具体细菌名称2]标准菌株。从[具体细菌名称1]和[具体细菌名称2]的液体培养物中取100μl,通过平板培养接种到穆勒-欣顿琼脂中,同样量接种到沙氏葡萄糖琼脂中。将MTA Plus、BioDentine和ERRM无菌填充到开放的凹坑中。此后,将培养基置于37°C干燥箱中24、48和72小时,测量抑菌圈直径。
采用Kruskal-Wallis、[具体检验方法1](Mann-Whitney)、Friedman和[具体检验方法2](Wilcoxon符号)检验进行统计分析。
在三组中,BioDentine对[具体细菌名称1]的抗菌活性在统计学上高于MTA Plus和ERRM(P<0.05)。MTA Plus对[具体细菌名称2]的抗真菌活性在统计学上高于BioDentine和ERRM(P<0.05)。ERRM在三组中对[具体细菌名称1]和[具体细菌名称2]显示出最小的抑菌圈(P<0.05)。
在三组中,BioDentine表现出最大的抗菌活性,MTA Plus表现出最大的抗真菌活性。ERRM在三组中表现出最小的抗菌和抗真菌活性。
