ROLE OF MTA IN ENDODONTICS

ROLE OF MTA IN ENDODONTICS MTA nowadays also comes in a single-use treatment kit like - Waldent Endolife MTA is a hydrophilic and biocompatible mineral trioxide aggregate cement that is capable of stimulating healing and osteogenesis. COMPOSITION- • Mineral trioxide aggregate (MTA) is composed of Portland cement and bismuth oxide in 4:1. Bismuth oxide is added for radiopacity. • So, it consists of a powder of fine trioxides such as (tricalcium oxide, silicate oxide, and bismuth oxide) and other hydrophilic particles like (tricalcium silicate and tricalcium aluminate) TYPES OF MTA- Grey MTA and White MTA Waldent endo-life MTA is a white MTA so it doesn’t cause any discoloration which makes it perfect for aesthetic purposes. INDICATIONS- MTA is used for perforation repairs, apexification, as a root-canal sealant, tooth fracture repair, regenerative procedures, apexogenesis, pulpotomies, and as pulp-capping material. FEATURES- • Waldent Endo life MTA is white in colour so it is perfect for aesthetic purposes. • The setting time is around 15 mins which is way less than the typical (grey) MTA which is around 2-4 hours • It has low compressive strength, low solubility, and high radio-opacity than dentine. • Its alkaline pH of 12.5 favours antibacterial effects, so hard tissue formation can be induced after applying this substance as an apical obturation material. • Due to the presence of bismuth oxide, it is radiopaque which makes it easy to visualize on the radiograph • It has the capacity to induce bone, dentin, and cementum formation and regeneration of periapical tissues (periodontal ligament and cementum). • As MTA expands after setting, it has a good marginal sealing property. • It is antibacterial and anti-fungal • It is also biocompatible in nature. MANIPULATION- • powder water ratio should be 3:1. Mixing can be done on a paper pad or glass slab with a plastic or metal spatula to achieve a putty-like paste consistency. This mix should be covered with a moist cotton pellet to prevent dehydration of the mix. • The mix is then placed in the desired location and condensed lightly with a moistened cotton pellet • MTA has a pH of 10.2 immediately after mixing. By the end of 3hrs, the pH increases to 12.5 similar to that of calcium hydroxide. Hence, mixing time should be less than 4 min.
