Comparative evaluation of setting time and sealing ability of two root end filling materials: An In vitro Study

Purpose: Incomplete root formation caused due to trauma can lead to problems in future. Treating such open apices teeth pose a challenge. Apexification is one of the treatment options for such teeth with open apex. Thus, this in vitro study intended to assess and compare two commercially available root-end filling materials mineral trioxide aggregate (MTA)-Angelus and Biodentine™ for their setting time and sealing ability. Materials and Methods: This in vitro study assessed the setting time and sealing ability of the two materials; MTA-Angelus and Biodentine™. For setting time evaluation, 30 rings were made and divided into two groups. The evaluation was done using Vicat apparatus. For sealing ability, sixty single rooted teeth were used and were divided into four groups (two experimental and two control). The assessment was done using the linear dye penetration method. Results: Mean setting time of Biodentine and MTA was 29.2 ± 3.84 min and 15.2 ± 2.11 min, respectively. The mean linear dye penetration in MTA group was found to be 0.808 ± 1.094 mm, 3.76 ± 1.05 mm in Biodentine group, 5.28 ± 1.73 mm and 0.05 mm in positive control group. Conclusion: MTA-Angelus demonstrated a faster setting time when compared to biodentine, while biodentine showed to have a superior sealing ability.
