It is difficult to completely eradicate microorganisms from the infected root canal system. Intracanal irrigants seem necessary for eradication of infected tissues and microorganisms in addition to mechanical debridement. Continuous use of chemical antimicrobial agents leads to serious side effects. Therefore, the need arises for alternative agents to overcome the disadvantages of their chemical counterparts.
To evaluate and compare the antimicrobial efficacy of three endodontic irrigants against clinically isolated bacteria found in root canals containing necrotic pulp.
Preirrigation sample were collected using sterile paper points and sent for microbial count. Chemomechanical preparation was performed, and the root canals were irrigated with 5 mL of test samples. After 3 days, the patient was recalled, and a postirrigation sample was collected and sent for microbial count.
Both 3.8% silver diamine fluoride (SDF) and 3% sodium hypochlorite (NaOCl) showed a superior capacity to sterilize the root canals compared to the neem group.
The use of SDF as an endodontic irrigant is feasible as it effectively removes the microbes present in the canal.
Silver diamine fluoride has not been shown to be cytotoxic or carcinogenic, unlike NaOCl, suggesting it could be used as a potential endodontic irrigant. However, few studies have evaluated the antimicrobial efficacy of SDF as an endodontic irrigant.

从感染的根管系统中完全根除微生物很困难。除了机械清创外,根管冲洗剂似乎对于根除感染组织和微生物是必要的。持续使用化学抗菌剂会导致严重的副作用。因此,需要替代剂来克服其化学同类物的缺点。
评估和比较三种根管冲洗剂对含有坏死牙髓的根管中临床分离细菌的抗菌效果。
使用无菌纸尖收集冲洗前样本并送去进行微生物计数。进行化学机械预备,并用5毫升测试样本冲洗根管。3天后,召回患者,收集冲洗后样本并送去进行微生物计数。
与印楝组相比,3.8%氟化银氨(SDF)和3%次氯酸钠(NaOCl)在根管消毒方面表现出更强的能力。
使用SDF作为根管冲洗剂是可行的,因为它能有效清除根管中的微生物。
与NaOCl不同,氟化银氨未显示出细胞毒性或致癌性,这表明它可作为一种潜在的根管冲洗剂。然而,很少有研究评估SDF作为根管冲洗剂的抗菌效果。
