Sealing efficacy of titanium-doped versus conventional MTA in access perforation repair: An in vitro study

Mineral trioxide aggregate (MTA) is known for good sealing and also for its biocompatibility. However, limitations such as extended setting time and potential leakage persist. Therefore, it is of interest to compare the sealing efficacy of titanium-doped MTA and conventional MTA in the repair of access perforations using in vitro dye penetration model fourty extracted human mandibular premolars were used. Titanium-doped MTA showed significantly less dye penetration (mean 0.92 mm) compared to conventional MTA (mean 1.46 mm) (p = 0.001), indicating superior sealing efficacy. Thus, Titanium-doped MTA demonstrates better sealing capability than conventional MTA and may serve as an improved material for perforation repair.
