Sealing Efficiency of MTA, Accelerated MTA, Biodentine and RMGIC as Retrograde Filling Materials

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