MTA Carrier Straight is a kind of dental material used for mending and filling teeth that have been chipped, cracked, or infected. It is constructed of mineral trioxide aggregate (MTA), a mix of tiny Portland cement, bismuth oxide, and other mineral particles. The straight carrier is intended to be administered using a specific applicator to give a smooth and precise application in straight, narrow root canals.
