The ideal root end filling material should form a tight seal in the root canal by adhering to the cavity walls. Several materials have been used for root end filling. The present study aims to find out and compare the bioactivity of Neo MTA Plus, Pro Root MTA White, BIODENTINE & glass ionomer cement as root end filling materials using 1% methylene blue as tracer.
80 extracted human permanent maxillary anterior teeth were used in the study. They were divided into four groups. Specimens were sectioned transversely in the cervical area to separate the crown from the root. The root canal was obturated with gutta percha and zinc oxide eugenol sealers. Thereafter, each sample was resected apically by removing 3 mm of the apex and filled with different materials. Samples were kept in buffering solution at 37 °C until the recommended evaluation periods. The specimens were then suspended in 1% methylene blue for 24 h, prior to the analysis. The teeth were then sectioned, and dye penetration was examined, photographed, and evaluated under a stereomicroscope.
Vertical dye penetration showed significant differences across different groups. The minimum dye penetration was seen in Neo MTA plus followed by BIODENTINE, Pro Root MTA and maximum in GIC. There was no significant difference in dye penetration between Neo MTA plus and BIODENTINE both at fifteen days and one-month intervals.
The present study suggests Neo MTA plus and BIODENTINE should be the preferred material for root end filling.
理想的根尖充填材料应通过粘附于根管壁在根管内形成紧密密封。已有多种材料用于根尖充填。本研究旨在使用1%亚甲蓝作为示踪剂,找出并比较Neo MTA Plus、Pro Root MTA White、BIODENTINE和玻璃离子水门汀作为根尖充填材料的生物活性。
本研究使用了80颗拔除的人类上颌恒前牙。将它们分为四组。在颈部区域横向切割标本,将冠部与根部分离。根管用牙胶尖和氧化锌丁香酚封闭剂充填。此后,每个样本在根尖处切除3mm的根尖,并填充不同材料。样本在37℃的缓冲溶液中保存至推荐的评估期。然后在分析前将标本悬浮于1%亚甲蓝中24小时。然后将牙齿切片,在体视显微镜下检查、拍照并评估染料渗透情况。
不同组之间垂直染料渗透显示出显著差异。Neo MTA plus组的染料渗透最小,其次是BIODENTINE、Pro Root MTA,玻璃离子水门汀组最大。在15天和1个月的间隔时,Neo MTA plus和BIODENTINE之间的染料渗透没有显著差异。
本研究表明Neo MTA plus和BIODENTINE应是根尖充填的首选材料。
