The aim of this study was to evaluate the effects of newly proposed irrigants; the pomegranate, apple cider, and grape vinegars in comparison with contemporary irrigants; sodium hypochlorite (NaOCl), chlorhexidine gluconate (CHX), and octenidine-hydrochloride (OCT) on microhardness and surface roughness of human root canal dentin.
The crowns of the 105 mandibular incisor teeth were removed, and roots were separated longitudinally. Root halves were embedded in acrylic-resin and were ground flat. The specimens were randomly divided into following six test groups ( = 30); pomegranate vinegar, apple cider vinegar, grape vinegar, 2.5% NaOCl, 2% CHX, OCT and a control group based on the treatment time, samples were then divided into two subgroups (15 min or 30 min). Each specimen was first subjected to surface roughness and then Vickers microhardness testing. The data were statistically analyzed.
Pomegranate, apple cider, and grape vinegars exhibited similar roughness values ( > 0.05) and presented higher results than other groups ( < 0.05). There was no statistically significant difference between the microhardness values of the irrigant groups ( > 0.05). The microhardness decreased when the exposure time increased from 15 min to 30 min ( < 0.05).
The use of vinegar for endodontic irrigation may have a softening effect on root canal dentin with time and may increase dentin roughness.
本研究旨在评估新提出的冲洗剂——石榴醋、苹果醋和葡萄醋，与当代冲洗剂——次氯酸钠（NaOCl）、葡萄糖酸氯己定（CHX）和盐酸奥替尼啶（OCT）相比，对人根管牙本质显微硬度和表面粗糙度的影响。
拔除105颗下颌切牙的牙冠，将牙根纵向分开。将半根牙根嵌入丙烯酸树脂中并磨平。根据治疗时间将标本随机分为以下六个试验组（每组n = 30）：石榴醋组、苹果醋组、葡萄醋组、2.5% NaOCl组、2% CHX组、OCT组，以及一个对照组。样本再分为两个亚组（15分钟或30分钟）。每个标本首先进行表面粗糙度测试，然后进行维氏显微硬度测试。对数据进行统计学分析。
石榴醋、苹果醋和葡萄醋表现出相似的粗糙度值（P > 0.05），且比其他组的结果更高（P < 0.05）。冲洗剂组的显微硬度值之间无统计学显著差异（P > 0.05）。当暴露时间从15分钟增加到30分钟时，显微硬度降低（P < 0.05）。
根管冲洗使用醋随着时间推移可能会对根管牙本质产生软化作用，并可能增加牙本质粗糙度。
