Sealing efficiency of MTA, accelerated MTA, Biodentine and RMGIC as retrograde filling materials

Background/Aim: This in-vitro study evaluated the apical-sealing ability of MTA, MTA+10% CaCl2, Biodentine™ and RMGIC when used as retrograde material. Material Methods: A total 80 single-rooted bovine incisors were decoronated, instrumented, divided into 4 groups according to material, follows: Group 1: MTA (ProRoot Dentsply); 2: Dentsply) + 10% CaCl2; 3: Biodentine (Biodentine®, Septodont); 4: (Nova Glass - LC, Imicryl). Root surfaces isolated with nail Polish, teeth immersed in 2% methylene blue dye at 37°C for 48 h. The extent penetration (mm) was measured under a stereomicroscope. Results: had highest mean-rank score (MP=49.05), followed by (MP=43.65), (35.95) MTA+CaCl2 (MP=33.35). results paired comparison tests found mean microleakage value CaCl2 (Group 3) be significantly lower than that (respectively; p=0,020, p=0,019). No significant difference other group comparisons (p> 0.05). Conclusions: These suggest addition an accelerator may reduce following endodontic surgery. can alternative on obturation.
