将45颗离体牙随机分为3组，每组10颗。在第一组中，仅使用树脂改性的玻璃离子材料（Vitrebond）进行根分叉穿孔。第二组和第三组分别使用硫酸钙和羟基磷灰石作为Vitrebond下的人工地板。纸浆室和入口用复合树脂填充。在2%亚甲蓝溶液中浸泡2周后，将牙齿切片，并使用NIH Image 1.47 Macintosh程序在立体显微镜下测量染料渗透。结果表明，硫酸钙和羟基磷灰石人工地板显着提高了Vitrebond的密封能力，并提供了成功的屏障，防止其过度延伸。
Access openings and furcation perforations were prepared in 45 human extracted teeth randomly divided into three equal groups. Furcation perforations were obtruded using only a resin-modified, glass-ionomer material (Vitrebond) in the first group. Calcium sulfate and hydroxylapatite were used as artificial floors under the Vitrebond in the second and third groups, respectively. Pulp chambers and access openings were filled with composite resin. After immersion in 2% methylene blue solution for 2 wk, the teeth were sectioned and dye penetration was measured under a stereomicroscope using a NIH Image 1.47 Macintosh program. Results indicated that calcium sulfate and hydroxylapatite artificial floors significantly improved the sealing ability of Vitrebond and provided successful barriers against its overextension.
