Abstract

Background and objective: The choice of different root canal sealers can influence the amount of apical microleakage. This study aims to assess the microleakage of four different sealants used in root canals.

Methods: This l in vitro study was conducted from June 2022 to June 2023 in Duhok city in research medical lab at college of medicine. A total of eighty human extracted 1^st premolar teeth were extracted and used. The crowns were removed, and the root canals were prepared. The specimens were assigned at random to four groups (n=10) according to the type of sealer used and the two obturation techniques applied. The outer sides of the samples were coated with nail polish to provide insulation. Following the completion of the endodontic procedure, the samples were immersed in methylene blue dye for a duration of 72 hours. Each group was assessed for microleakage using graduated microscope.

Results: The study showed that maxima Mineral trioxide aggregate bioceramic had the lowest level of microleakage of 0.5mm, on other hand, Zinc Oxide Eugenol-Single Cone exhibited the greatest level of microleakage of 2.5mm, the difference was significant with p-value <0.0001, and for the thermafill technique the mean value was 0.68 while for the single cone was 2.19 with the p- value < 0.0001 which was also significant.

Conclusion: maxima showed the best results in microleakage however, there is no technique or materials that completely eliminate leakage at all.
