Abstract:

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.

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
