An essential part of root canal cleaning is irrigating the system to remove any remaining debris and tissue remains. The purpose of root canal therapy is to shape and clean the endodontic space, reduce the bacterial burden, and remove the pulp tissue. In this research, several irrigation solutions with and without sonic irrigation were evaluated to see how quickly tissue dissolves.
A tissue sample was taken from a cow (68 ± 3 mg) with no statistically significant difference between groups. All five test tubes in each group were immersed in irrigant, and each group contained one subgroup with five test tubes. Separate weights were recorded for every irrigant that had been passed through the filter paper. Thus, the quantity of pulp dissolved by different irrigating solutions was quantified using a filtering technique.
It was revealed that there was a substantial difference between the groups. Sonic and non-sonic irrigation of sodium hypochlorite resulted in a substantial difference in tissue disintegration.
This research found that sodium hypochlorite was more effective than EDTA and saline in dissolving pulp. Despite several studies claiming that neem has potent antibacterial activities, tissue dissolution has not been shown in experiments using this herb.
根管清理的一个重要部分是冲洗根管系统，以清除任何残留的碎屑和组织残渣。根管治疗的目的是塑造和清理根管空间，减轻细菌负荷，并去除牙髓组织。在本研究中，评估了几种有无超声冲洗的冲洗液，以观察组织溶解的速度。
从一头奶牛身上采集组织样本（68±3毫克），各组之间无统计学显著差异。每组的所有五个试管都浸入冲洗液中，每组包含一个有五个试管的亚组。记录通过滤纸的每种冲洗液的单独重量。因此，使用过滤技术对不同冲洗液溶解的牙髓量进行了量化。
结果显示各组之间存在显著差异。次氯酸钠的超声冲洗和非超声冲洗在组织崩解方面产生了显著差异。
本研究发现，次氯酸钠在溶解牙髓方面比乙二胺四乙酸（EDTA）和生理盐水更有效。尽管有几项研究称印楝具有强大的抗菌活性，但在使用这种草药的实验中尚未显示出组织溶解现象。
