Aim: To compare and evaluate the microleakage in the apical portion after placement of apical plug using Portland cement, mineral trioxide aggregate (MTA), and Biodentine.
Materials and methods: About 36 maxillary central incisors were disinfected with 5.25% NaOCl. The apices were trimmed by 3 mm, and the coronal portions were reduced to a 15 mm working length. Canals were prepared with ISO #80 K-file and step back to ISO #120 K-file, irrigated with 3% NaOCl, 17% ethylenediaminetetraacetic acid (EDTA), and saline. The samples were subsequently categorized into three distinct groups: group I = 4 mm apical plug with Portland cement, group II = 4 mm apical plug with MTA, group III = 4 mm apical plug with Biodentine. After setting, canals were obturated using gutta-percha and AH Plus sealer, and access cavities were restored with glass ionomer cement (GIC). Teeth were stored in 100% humidity, submerged in 2% methylene blue for 72 hours, and thereafter divided into sections to assess dye penetration using a stereomicroscope. One-way ANOVA was used in the statistical analysis to identify significant differences among the groups at an alpha level of 5%.
Results: Biodentine (0.38 ± 0.27 mm) demonstrated superior performance to stop microleakage in comparison to Portland cement (2.1 ± 0.74 mm) and MTA (1.1 ± 0.42 mm).
