Abstract

Aim; The purpose of this study was to evaluate the sealing ability of a newly introduced adhesive root canal sealer (MetaSEAL™, Parkell, USA) and other root canal filling materials. Materials and methods; Thirty-two single-rooted human mandibular premolars were used. The crowns were removed and the root lengths were standardized to 12mm. Four teeth were used as controls: two teeth were used as negative controls and the other two as positive controls. The remaining 28 teeth were randomly divided into 4 groups of 7 teeth each and filled with one of the following methods: Group A: Resilon™ (Pentron, USA)+Epiphany™ sealer (Pentron) using lateral condensation Group B: Gutta-percha point (GC)+Sealapex sealer (SybronEndo, USA) using lateral condensation Group C: Gutta-percha point+Superbond sealer (SunMedical) using single-cone technique Group D: Gutta-percha point+MetaSEAL™ using single-cone technique After the canal sealers set, a polypropylene tube that contained 0.06% methylene blue dye solution was attached to the coronal portion of each root. Two millimeters of the apical portion was immersed in distilled water within a glass bottle. The amount of dye emerging through the root into the water was measured with a spectrophotometer at 1, 4, 8, 15 and 30 days after the immersion. Data obtained were statistically analyzed using ANOVA and Tukey-Kramer at the 5% significance level. Results; There were significant differences among the groups and experimental time intervals (p<0.05; 2-way ANOVA). Statistical analysis revealed that the amount of leaked dye in the MetaSEAL™ group on the 30th day was significantly less than that in the other three groups (p<0.05). Conclusions; Under the conditions of this study, the sealing ability of MetaSEAL™ was significantly better than that of the other three different types of sealers.
