An in vitro study of the Sealing Ability of Materials Used for Furcation Perforation Treatment

Neringa Skucaite, Kastytis Busauskas


The aim of the study was to determine the sealing ability in vitro of the materials used for furcation perforation (FP) treatment, using Methylen blue dye. Thirty extracted human molar multi-rooted teeth and a synthetic bone substance (Bioplant HTH), amalgam, and MTA (mineral trioxide aggregate) were used in this study. The access openings to all teeth canals were made, and 1.5 mm diameter FPs were drilled. A sponge and wax were used to surround FP , and the teeth were plastered. The teeth were randomly divided into three groups: A (filled with amalgam), B (amalgam and HTR as internal matrix), C (filled with MTA). The whole surface of the teeth was covered in nail varnish, except for the site of the perforation. The teeth were immersed in Methylen blue dye for 4 days, in temperature +37°C. Vertical incisions were made and excess of the amalgam were measured in Groups A and B, dye penetration(mm) in all groups. The dye leakage was observed in all teeth groups, however, in Group C (filled with MTA) it was significantly less (p<0.001). Synthetic bone substance, using it as an internal matrix, reduced the penetration of filling material into the periodontium to the minimum.

Key words: Furcation perforation, MTA (mineral trioxide aggregate), sealing ability, internal matrix.
