One among the various reasons for root canal failure in endodontics is the leakage of an intracanal medicament due to improper coronal sealing.
To assess the coronal leakage of two intracanal medicaments sealed with two different temporary filling materials.
An study was done on 55 teeth where they were divided into three groups with two root canal medicaments namely calcium hydroxide + 0.2% chlorhexidine solution, triple antibiotic paste, and a control group. These three groups were restored temporarily with MD Temp and IRM, and these samples were checked for coronal leakage after 30 days.
The group, triple antibiotic paste with IRM stayed for more number of days without leakage with the mean of 24.5 days, followed by group triple antibiotic paste with MD Temp. The least coronal leakage was seen in group MD Temp without Intracanal medicament with the mean of eight and half days followed by group IRM without Intracanal medicament. When comparing the two temporary filling materials without any medicament, there was no significant difference between the same. When comparing within MD Temp group, the least microleakage was seen with Triple antibiotic paste with MD Temp. In the IRM group, the least microleakage was seen with Triple antibiotic paste with IRM.
Triple antibiotic paste was found to be the most promising intracanal medicament with an appropriate seal.
The best intracanal medicament, which is triple antibiotic paste in the present study could prevent microorganism leakage and inhibit bacterial growth.

牙髓病学中根管治疗失败的各种原因之一是由于冠部封闭不当导致根管内药物渗漏。
评估用两种不同的临时充填材料密封的两种根管内药物的冠部渗漏情况。
对55颗牙齿进行研究,将其分为三组,使用两种根管内药物,即氢氧化钙+0.2%氯己定溶液、三联抗生素糊剂,以及一个对照组。这三组分别用MD Temp和IRM进行临时修复,30天后检查这些样本的冠部渗漏情况。
三联抗生素糊剂与IRM组保持无渗漏的天数更多,平均为24.5天,其次是三联抗生素糊剂与MD Temp组。在无根管内药物的MD Temp组中,冠部渗漏最少,平均为8.5天,其次是无根管内药物的IRM组。比较两种无任何药物的临时充填材料时,两者之间无显著差异。在MD Temp组内比较时,三联抗生素糊剂与MD Temp的微渗漏最少。在IRM组中,三联抗生素糊剂与IRM的微渗漏最少。
三联抗生素糊剂被发现是最有前景的根管内药物,具有适当的密封效果。
本研究中最佳的根管内药物三联抗生素糊剂可防止微生物渗漏并抑制细菌生长。巴拉吉S、库马尔K、文卡特桑R、克里希纳穆尔蒂S、马诺哈兰V、马里穆图S。两种根管内药物暴露于人类唾液后的冠部渗漏评估——一项研究。《国际临床儿科牙科学杂志》,2018年;11(5):406 - 411。
