目的:一个intracanal药剂用于:(i)运河仪器后消除任何剩余的细菌;(2)减少根尖周的炎症组织和纸浆残余;(3)使运河内容惰性和中和组织碎片;(iv)作为一个障碍对泄漏从临时灌装;(v)帮助干持续湿运河。本研究进行评估和识别不同的车辆使用Ca (OH) 2在释放更多有效钙和羟基离子以更少的其他组件使用的为病人提供最大利益。材料andMethods:使用高效液相色谱法(HPLC),少量的液体样品在25前磨牙浸人的牙齿被评估。氢氧化钙是保存在不同的车辆:组1聚乙二醇和树脂;组2甘油,樟脑para-monochlorophenol (PMCC) PMCC和樟脑;组3 PMCC; group Group 4 glycerin Tricresol formal (TCF – 19% formaldehyde, 10% cresol); Group 5 Anesthetic solution Lignox. Five polyethylene tubes were filled with each of these pastes and placed unsealed in similar bottles. At the end of this period, HPLC analyses of the aqueous medium related to each group were performed to detect the diffusion pattern of Ca(OH) 2 along with other substances that had diffused from pastes used in the canals of the teeth other than calcium and hydroxyl ions. Results: Although the groups presented different maximum peaks when there was no barrier, they all showed higher values than when the tooth was present. At least maximum number of substances other than Calcium and hydroxyl ions were detected in the group 4. Conclusion: Considerable quantities of other components of the pastes used to deliver Ca (OH) 2 diffused through the dentine and reached the external root surface along with calcium and hydroxyl ions. Further studies will be needed to understand whether there are any adverse effects of such diffusing components on periodontium.
