使用染料提取渗漏法评价了两种矿物三氧化物聚合物（MTA）化合物和中间修复材料（MEBO）封闭大型分叉穿孔的能力。在放置修复材料之前，使用和不使用内部基质修复分叉穿孔。选取80颗离体下颌第一磨牙，根据修复材料的不同分为阳性组（n = 10）、阴性组（n = 10）和3个实验组（n = 20）。每个实验组根据是否使用内基质分为两个亚组（n = 10）。染料泄漏测试从正交方向，并使用全浓度硝酸进行染料提取。使用分光光度计在550 nm处测量染料吸光度。具有和不具有内部基质的ProRoot MTA（Maillfer，Dentsply，Switzerland）和具有内部基质的MTA-Angelus（Angelus，Londrina，PR，Brazil）显示最小的染料吸光度。没有内部基质的染料（Caulk，Dentsply，米尔福德，DE）显示最高的染料吸光度。内基质组与无内基质组之间差异不显著，处于中间水平。
The ability of two mineral trioxide aggregate (MTA) compounds and Intermediate Restorative Material (IRM) to seal large furcation perforations were evaluated using a dye-extraction leakage method. The furcation perforations were repaired with and without the use of internal matrix before placement of repair material. Eighty extracted human mandibular first molars were divided into positive (n = 10), negative (n = 10), and three experimental groups (n = 20) according to the repair material used. Each experimental group was divided into two subgroups (n = 10) according to whether internal matrix was used or not. Dye leakage was tested from an orthograde direction, and dye extraction was performed using full concentration nitric acid. Dye absorbance was measured at 550 nm using spectro photo meter. ProRoot MTA (Maillfer, Dentsply, Switzerland) with and without internal matrix and MTA-Angelus (Angelus, Londrina, PR, Brazil) with internal matrix showed the least dye absorbance. IRM (Caulk, Dentsply, Milford, DE) without internal matrix showed the highest dye absorbance. IRM with internal matrix and MTA-Angelus without internal matrix had insignificant difference and came at intermediate level between the other groups.
