N1N,'-十亚甲基-N4N4'-十亚甲基-双-4氨基茚二乙酸酯 (Salvizol) 是一种化疗和杀菌化合物（默克索引，第 8 版，1968 年），与 EDTA 类似，已被发现可有效用于根管的化学机械制备（KAUFMAN，IADR 摘要）。在本研究中，比较了牙本质粉在 Salvizol 中的溶解度与 EDTA 中的溶解度。研究了处理后的牙本质在酸中的溶解度，并与用十二烷基硫酸钠 (SLS) 预处理的牙本质进行了比较。将 30 毫克等份的粉碎牙本质（100 目）暴露于 5 毫升 Salvizol（0.5%，pH = 4.7）、EDTA（0.5%，pH = 6.8）、盐水（pH = 6.8）、去离子水（pH -5.1）和 SLS（0.5%，pH = 6.6）中 1、2、18 和 30 小时。室温。吸去上清液后，将处理过的牙本质用3ml去离子水洗涤3次，在90℃下干燥并称重。 10毫克等份
N1N,'-decamethylene-N4N4'-decamethylene-bis-4aminochinaldinium diacetate (Salvizol), a chemotherapeutic and bactericidic compound (Merck Index, 8th ed, 1968) has been found, similar to EDTA, effective for chemomechanical preparation of root canals (KAUFMAN, IADR abstract). In the present study, the solubility rate of dentin powder in Salvizol is compared with that in EDTA. The subsequent solubility of the treated dentin was studied in acid and compared to that of dentin pretreated with sodium lauryl sulfate (SLS). Thirty mg aliquots of pulverized dentin (100 mesh) were exposed to 5 ml of Salvizol (0.5%, pH = 4.7), EDTA (0.5%, pH = 6.8), saline (pH = 6.8), deionized water (pH -5.1) and SLS (0.5%, pH = 6.6) for 1, 2, 18 and 30 hours at room temperature. After drawing off the supernatant liquid, the treated dentin was washed 3 times with 3 ml deionized water, dried at 90 C and weighed. 10-mg aliquots of the
