The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth, when obturated using a combination of zinc oxide and iodoform paste (Endoflas F.S.).
A group of 29 patients aged 3-9 years and a total of 64 teeth were selected. These 64 teeth (32 anterior teeth=32 canals, and 32 posterior teeth=80 canals) were randomly divided into 4 groups. Teeth were obturated with Lentulo spiral, pressure syringe, bi-directional spiral and Pastinject. Post-operative evaluation was done for: quality of canal obturation, (underfilled, optimally filled, overfilled) and presence of voids.
Pastinject exhibited the highest number of optimally filled canals, while the highest number of underfilled canals were observed with bi-directional spiral, and the highest number of overfilled canals were observed with pressure syringe. A minimum number of voids was present in canals filled with the Pastinject technique and pressure syringe.
These results suggest that Pastinject was the most effective technique for obturation of primary teeth.
本体内研究旨在评估和比较使用氧化锌和碘仿糊剂(Endoflas F.S.)联合填充时,用于乳牙的不同封闭方法的效果。
选择了一组 29 名 3-9 岁的患者,共 64 颗牙齿。这 64 颗牙齿(32 颗前牙=32 个根管,32 颗后牙=80 个根管)随机分为 4 组。使用 Lentulo 螺旋、压力注射器、双向螺旋和 Pastinject 进行根管填充。术后评估包括:根管填充质量(欠填、适填、过填)和有空腔存在的情况。
Pastinject 显示出最佳填充根管数量最多,而双向螺旋观察到的欠填根管数量最多,压力注射器观察到的过填根管数量最多。使用 Pastinject 技术和压力注射器填充的根管中存在的空腔最少。
这些结果表明,Pastinject 是乳牙封闭最有效的技术。
