One of the most important factors for successful endodontic therapy is root canal cleaning. The difficulty involved in eliminating microorganisms, as well as their residual presence, warrants the use of root canal dressings after bio-mechanical preparation.
The aim of the study was to compare the diffusion ability between nonalcoholic calcium hydroxide-propolis paste, calcium hydroxide-saline paste, and calcium hydroxide-propylene glycol paste.
For this proposed study, single-rooted extracted permanent teeth were randomly divided into three groups to fill the canals: group I: Calcium hydroxide-propylene glycol paste, group II: Calcium hydroxide-saline paste, and group III: Calcium hydroxide-propolis paste. After complete filing of the root canal, the pH values of the solutions in the flasks are measured at an interval of 3, 24, 72, 168 hours.
After 168-hour interval, it was noticed that the mean pH obtained by calcium hydroxide-propolis paste was 10.54 (± 0.38), which was greater than calcium hydroxide-propylene glycol paste 9.70 (± 0.45) and calcium hydroxide-saline paste 9.16 (± 0.30) consecutively.
The nonalcoholic calcium hydroxide-propolis paste used during the study was able to diffuse through the dentinal tubules. Thus, it can be used as a vehicle for calcium hydroxide.

根管清理是牙髓病治疗成功的最重要因素之一。清除微生物及其残留存在的困难性,使得在根管机械预备后需要使用根管敷料。
本研究旨在比较非酒精性氢氧化钙-蜂胶糊剂、氢氧化钙-盐水糊剂和氢氧化钙-丙二醇糊剂的扩散能力。
对于本研究,将单根拔除的恒牙随机分为三组进行根管充填:第一组:氢氧化钙-丙二醇糊剂,第二组:氢氧化钙-盐水糊剂,第三组:氢氧化钙-蜂胶糊剂。根管完全充填后,每隔3、24、72、168小时测量烧瓶中溶液的pH值。
168小时后,发现氢氧化钙-蜂胶糊剂的平均pH值为10.54(±0.38),依次大于氢氧化钙-丙二醇糊剂的9.70(±0.45)和氢氧化钙-盐水糊剂的9.16(±0.30)。
本研究中使用的非酒精性氢氧化钙-蜂胶糊剂能够通过牙本质小管扩散。因此,它可作为氢氧化钙的载体。Baranwal R、Duggi V、Avinash A、Dubey A、Pagaria S、Munot H。蜂胶:一种用于根管内药物的智能补充剂。《国际临床儿科学牙科杂志》2017年;10(4):324 - 329。
