Furcal perforations are one of the most challenging causes of endodontic failures. Several materials including MTA have been used for non surgical repair of these perforations. The aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using Root MTA and ProRoot MTA.
This in vitro study was conducted on 54 primary first molars that were randomly divided into the two experimental groups of 24 teeth each and two control groups (n=6). After preparation of access cavities, perforations were made and the perforation areas were repaired using either Root or ProRoot MTAs. After staining and preparation of mesiodistal longitudinal sections, dye leakage was measured using a stereomicroscope. The data was analyzed by the Mann Whitney statistical test. Significant level was set at 0.05.
The data indicated that the dye leakage of ProRoot MTA is significantly lesser than Root MTA (P=0.001).
ProRoot MTA showed good sealing ability in repairing furcal perforations of primary molars.
髓室底穿孔是导致牙髓治疗失败的最具挑战性的原因之一。包括MTA在内的几种材料已被用于这些穿孔的非手术修复。本研究的目的是比较使用Root MTA和ProRoot MTA治疗乳磨牙髓室底穿孔的治疗效果。
本体外研究对54颗乳上颌第一磨牙进行，随机分为两个实验组，每组24颗牙，两个对照组（n = 6）。制备开髓洞形后，制作穿孔，并使用Root MTA或ProRoot MTA修复穿孔区域。染色并制备近远中纵剖面后，使用体视显微镜测量染料渗漏情况。数据采用Mann Whitney统计检验进行分析。显著性水平设定为0.05。
数据表明，ProRoot MTA的染料渗漏明显少于Root MTA（P = 0.001）。
ProRoot MTA在修复乳磨牙髓室底穿孔方面显示出良好的封闭能力。
